Sunshine, Summer and Yellow Shirts

It’s been a busy summer here at GrowIt! headquarters. Actually you could say that GrowIt! headquarters itself has been on the road. We’ve been busy traveling across the country showing people what we’re up to, and connecting people to gardeners in their area.

Most recently, we took a trip out to the Washington, D.C. area, and had the chance to see our friends at Greenstreet Gardens! They’ve been uploading photos this spring and trying to help people with their plant problems. We also stopped by the Union Market in D.C. on Saturday and Sunday to hand out some free cucumber plants along with some t-shirts and good vibes! It was a great crowd, and we think we inspired some potential growers.

Earlier this summer we held a student contest. The idea was to see which students could get the most followers on GrowIt! We selected and interviewed five finalists, and then chose two winners from that group. Please join us in congratulating Brett Weiss and Sarah Swofford!

Brett is a student at Ferrum College, who had the awesome opportunity to intern with Disney this summer in their horticulture department. Brett sees the app as a cool way to find new plants and to show off his own collection!

Sarah is a student (and soon to be Graduate) at Texas A&M University. Sarah is what we would call an “ultra-fan” of GrowIt! as she was also a recipient of our student scholarship last fall. Sarah fell in love with horticulture almost by accident several years back. She’s now looking to find a career in the industry connecting people with plants.

Both of these students will be joining us in attending the Independent Garden Center Show in Chicago later this month. If you happen to be in attendance as well, please reach out to them and congratulate them!

As you may have seen throughout the summer, many brands have been holding photo contests on the GrowIt! platform. Some lucky users have actually won some hefty gift cards. Tomorrow, August 7^th, another contest begins. Suntory flowers is giving people the chance to win up to $100 for uploading a picture of a Sun Parasol Mandevilla onto GrowIt! with the hashtag #SunParasolRocks. It’s that easy to enter. While GrowIt! does not recommend any specific plants to all of its users, we do recommend that if you like/have a Sun Parasol Mandevilla that you upload it for a chance at some casshhhhhhh!

Power Picks – Indoor Plants

It’s The FINAL COUNTDOWN! Duh duh duh da da da……….

Yesterday Seth and I unleashed our top plant picks for the yard and for containers. By no means are those the only options. They might not even be the best options for your plantings. They are just plants that Seth and I believe in and like.

Today is the final round of our co-founder matchup.  Now that we’ve discussed the yard and containers, there’s only one major arena left: Indoor Plants.

Some of you will call them house plants or potted plants, but that doesn’t really sum it up. The plants we’re talking about today don’t discriminate. They don’t care if you live in a house, an apartment, or even that van down by the river! We’re talking about those plants that are staples in your scenery. Think of them more like plant pets.

So who has the better plant picks Seth or myself? You decide in this final (for now) roundup!

-Mason, Co-Founder of GrowIt! (mday55 on the app!)

The picks are in! Which Indoor Plants are your favorites?

Seth’s Top 3:

1. Used Orchids – The plant business guy in me encourages people to throw plants like orchids, poinsettias, and other potted plants away after they are done blooming. The plant nerd in me likes buying orchids that are discounted, just to see if I can bring them back to life, and get them to bloom.  Surprisingly, they are rather easy to care for; give them a bright indirect light (so don’t put them in the window, just a bright room), water them thoroughly once a week (I put them in my shower for a few minutes), and a lot of patience.  Summer is a good time for these types of projects because the light levels are really high.
2. Umbrella Plant – Ok, so this plant may be considered to be rather boring, BUT, this plant is  SO easy to take care of, I doubt anyone can kill it (I don’t mean for that to be a challenge). Another great thing about this plant, is you can easily keep it at any size that you want, just by snapping off its new growth. The plant in the photo has been that same size for the last 4 years. It’s easy! And I really do believe the green color adds an element to the living room that lacks when it isn’t there. The plant can also be found it brighter colors.
3. Echeveria – this is an easy to grow succulent that has been popping up on the app more and more. It has a nice blue hue to the foliage. The blooms’ bright orange color contrast the foliage in and exciting way that you just don’t get from a green plant. The plant nerd in me really likes the architecture of the plant and how it is completely different than most other plants.  It doesn’t require much water, so you will see it in many interesting containers.

Mason’s Undeniable Top 3:

1. Cyclamen – I really like Cyclamen because they are versatile. For most of us that live in the frozen north, cyclamen are considered a houseplant that we can bring outside for some well-deserved sunshine. However, in some parts of the country, cyclamen can be considered perennials that bloom year after year. The growth habit on these is awesome because it’s so controlled and the flower has to be one of the most beautiful on the planet.
2. Succulents and Cacti of ANY kind – Want to start gardening, but don’t know what to grow? Go to your nearest garden center and ask them to show you their succulent display. Even though you won’t find lots of blooms, you are going to see more shapes and textures than you thought possible from plants. You’ll see plants that look like rocks (lithops), plants that look like dishes (paddle plant), even plants that look like Shrek’s ears! These are the ultimate gateway plants.
3. Cylindrical Snake Plant – Snake Plants are common fixtures in office buildings around the world. However, the Cylindrical Snake Plant is a rarer beast. This thing looks like something straight out of Jumanji. Sometimes growers even “train” their plants with string and wire to get them to intertwine. Again, all about texture here and a very easy plant to care for.

Power Picks – Container Edition

Ding Ding Ding! It’s time for Round Two! In our last post you learned what plants Seth and I consider to be top performers in the yard. You also had the chance to see how Seth clearly isn’t as refined in his plant selections as I am.

It’s ok we still love him.

Now we’re bringing you our Top 3 picks for container use. These are plants that rock all summer long on the patio or balcony.

Again you get to decide which one of us has the better taste in plants!

-Mason, Co-founder of GrowIt!

The Picks are In! Who is King of the Container?!

Seth’s Top 3:

1. Mandevilla – This plant has vibrant colored flowers that love the full sun and can make a great center piece to any container.  Put this plant along with some sort of trellis and combine it with some plants that will trail to create an awesome combination container.  New breeding on this plant has helped create less vigorous plants that allow you to have the same great flower on a much smaller plant.
2. Tropical Hibiscus – If you think flowering plants are too boring for your taste, then I dare you to try out a hibiscus plant as the centerpiece for your containers.  These tropical plants are not hardy unless you live in the south, but are exquisite for summer.  They bloom all summer long and have big & bright flowers.  You can get these plants small or big; as a bush or as standard (this means it has the stem and then the ball of growth at the top, this is better if you are mixing it with other plants). They do well by themselves in a smaller container, or you can put them in a bigger container and add some flowers around it to create a nice combination.
3. Banana Plant – No, you will not get any bananas from this plant, but you will be adding a nice tropical feel to your containers.  A good banana plant can add some visual structure and appeal to a container.  They have some great varieties that have some darker colors in the leaves that can contrast your flowers.  It also adds come good height to a container.  Plus for me, adding that tropical feel to the Midwest just makes me happier! These plants love sun, so keep it in the sunniest spot and watch them flourish.

Mason’s Top Notch Picks:

1. Cannas – Want something tropical looking that won’t cost you an arm and a leg? Go with a Canna! These things are great centerpieces for any mixed container, and they come in a variety of colors. Red is the classic, but you can find pink, orange, and yellow as well! Putting some mixed containers by the pool? You definitely need to try a Canna or two.
2. Heuchera – You didn’t see that one coming did you?!?! One of the more recent trends has actually been to start bending the rules when it comes to mixed containers. You don’t have to plant strictly annuals in containers anymore. Swap out that coleus for a Heuchera. At first people might look at you like you’re crazy, but then they’re going to realize that you’re a friggin’ genius!
3. Ornamental Pepper – Color is cool, but texture is better! There’s no better way to “spice” up a container than to throw in some Ornamental Peppers. They come in all shapes, sizes, and colors. I also love these because they’re extremely heat tolerant. If you want something that can handle the summer burn, go with an Ornamental Pepper. If you’re really bold, maybe just use an edible variety in your containers. That’s what we call dual purpose!

We’d love to know your favorite plants for containers. Leave a comment or upload them to the app!  

Power Picks – Yard/Landscape Edition

At GrowIt! we see a lot of plants. I mean A LOT of plants. Seth and I literally travel the country to see plants. If we’re not checking out plant photos on the app, we’re out in the garden taking photos of our own.

Over the last year, one thing has become clear. Everyone has their own opinions on plants. Some of that depends on where you live. Plants that perform in Florida, just might not cut it in the tundra that is the upper Midwest. However, some of the opinions out there are just based on who you are.

To highlight examples of differing opinions, Seth and I thought we would give you our top 3 plant picks for landscape, container, and indoor use. I’ll let you be the judge at who has the better taste in plants….. but clearly it’s me.

-Mason, Cofounder of GrowIt!

The Picks for Yard/Landscape Use are in!

Seth’s Top 3:

1. Whopper (large) or Dragon Wing (medium) Begonia – These plants are dynamite! They thrive in shade and in sun. They have bright red or pink flowers that cover most of the plant. This plant pretty much looks awesome every time I see it.
2. Angelonia/Summer Snapdragon – If you are in the northwest, I apologize for picking this plant as it may not do too well for you. This plant loves heat and loves sun, and if it has enough of both can look really good in the landscape.  They have a bunch of great colors and it can get you outside the normal petunias if you are looking for something different.
3. Butterfly Bush – If you are a sucker for butterflies, then you have to try this plant out! It comes in an array of colors and many different sizes from a small 3′ bush to a large 8′ bush. It’s flowers are very fragrant, and butterflies love landing on the cone like flowers. It is a perennial for much of the country. It really has been one of my favorites for quite a few years.

Mason’s Even Better Top 3:

1. Lantana – The Michael Jordan of plants. Lantana is a garden champ. Here in the northern states it adds great color all summer and provides good coverage. Down South, Lantana is even better. It can actually grow into a small hedge! Some blooms even give you three colors at once. What more could you ask for?
2. Dusty Miller – No garden is complete without “The Dusty”. Dusty Miller is the single greatest accent plant on the market. Possibly the most underappreciated plant out there, Dusty Miller can grow almost anywhere, and can take a beating. From far it just looks like a white plant, but up close you see that there is a texture there like none other.
3. Salvia ‘Black and Blue’ – I will challenge you to find a truer blue in the plant kingdom. There are tons of purples and even some navy blues out there, but none is as blue as ‘Black and Blue’. This plant is a killer. It does well in the occasional dry spell and provides color all summer long. It’s also great in the fact that it gets pretty big and can provide some height in combination with all of those groundcovers.

For more pictures of these plants, search for them in the app in the Search feed under the “Plants” Tab.

5 Plants for Early Spring!

At GrowIt! we stand by the ideal that all men and women were created equal. However, we also believe that all plants were not. Some plants bloom all summer long, but don’t bloom in the cooler parts of spring. Whereas some plants like it cool, but stop flowering in June.

Here are 5 plants that you’ve probably been seeing quite a bit of recently. They perform best in the earlier spring months before it gets too hot. If you’re looking for some last minute color for your gardens, through May these might be ok for you. However, these plants are not going to last all summer… and that’s ok! Basically what we’re saying is: take pictures of these plants when you see them, because they are in their prime now, and they’re only going to decline from here.

1. Hellebores – These early spring blooming perennials are favorites in a lot of collector gardens. Very popular in the Pacific Northwest and are generally hardy up to Zone 5 with some varieties even managing to over winter in Zone 4. So as long as you aren’t seeing temps lower than -15 to -25 degrees Fahrenheit your chances are good at this popping up every year. Some varieties have an awesome lime green bloom color which is not easy to find in the plant world!

2. Erysimum or Wallflower – A great flower for beginner gardeners looking to dabble in those early spring bloomers. Erysimum offers a great range of colors. Also, it’s one of the spring-bloomers that prefers the sunny spots. If you live in a warmer area (not the tundra of the Midwest) you might even see this come back for you!

From User: chaletnursery

3. Bleeding Heart or Dicentra – This perennial has one of the most unique flowers. It actually looks like a heart! Beautiful pink and white blooms year after year. However, they often stop flowering when the summer heat starts setting in.

From User: sidraisch

4. Tulips and Daffodils – We couldn’t leave out these bulbs! While tulips and daffodils are some of the most famous plants across the globe, many forget that they do not last into the summer. This is why tulip festivals are always held in the early parts of spring. Sometimes even as soon as mid-May these will begin to go out of flower. Take photos of these ASAP before it’s too late!

From User: nickflax1

From User: mrsjenclarke

5. Osteospermum – Sometimes referred to just as “Osteos” these can be a little tricky. Most varieties on the market prefer the cooler spring temps over the heat of the summer. However, some companies are working on varieties that can stand up to the heat! Before you buy this one, be sure to check the tag to make sure you know whether you’re getting something for spring interest or something that might last a little longer.

From User: cleigh

Another spring flower of note is Pericallis or Cineraria. You might have seen a lot of these on GrowIt! recently! This is because Suntory Flowers is giving away $200 in total prizes to people who upload a picture of their Senetti brand pericallis onto GrowIt! with the hashtag #SenettiRocks in the comments! One winner will receive $100 and two second place winners will receive $50. How cool is that? You could win some cash for your garden just by uploading a photo!

Be sure to stay tuned as we’ll be getting ready to see even more color in the garden as the temps get warmer! Next time we’ll be talking about all those plants that love the heat!

It Doesn’t Get Any Better Than That!

Over the past weekend we were invited to be a part of Chalet Nursery’s Garden Faire event in Wilmette, Illinois. The first weekend in May is the grand opening of spring in the Midwest. When we showed up to the garden center, it was about a quarter to eight in the morning and there was already a line of people waiting to get inside! It’s clear that people had enough of Old Man Winter and wanted to get some plants in the ground.

We couldn’t have asked for a better weekend. It was 70 degrees and sunny for the most part. Also, we were able to camp out next to the popcorn guy so that wasn’t bad either!

Plants looked great as well, and the selection was fantastic. Even though some of the more prominent summer annuals weren’t available yet, the wallflowers looked fantastic and so did the lobelia baskets.

We held a raffle as well! Four lucky people are set to win $25 gift certificates to Chalet Nursery and four luckier people are set to win GrowIt! t-shirts. We also had an AMAZING run-in with one of our GrowIt! fans this weekend as well!

Google Maps, Facebook, Twitter, Pandora, Youtube.

Those are all examples of mobile apps that are the first thing downloaded when someone gets a new phone. This past weekend, we learned that you can now add GrowIt! to that list!

Last summer while we were doing events in the Chicagoland area we had the chance to talk to a lot of people about what we are doing with GrowIt! Because we are currently only a mobile platform some people couldn’t use GrowIt! from the beginning because they didn’t have a smartphone. Turns out that we left an impression on those folks too!

We actually had one fan stop by – in a GrowIt! t-shirt no less – and tell us that last summer she was unable to use the app because she did not have a smartphone. However, she said that back in December she finally upgraded to an iPhone. Can you guess what the first app she downloaded was? Yep! It was GrowIt! We honestly, thought she was kidding at first but she assured us that she downloaded it right at the Apple Store! How cool is that?

She now uses the GrowIt! app as username “booter13”, and really enjoys helping people identify plants that they have questions about. She said that it’s a lot of fun and that she enjoys spreading her passion for gardening.

At the end of the day that’s what GrowIt! is all about: Spreading a passion for plants. We’re just glad we can make people smile while doing it. It truly was a great weekend capped by an AWESOME interaction with one of our users.

Bring On Spring!

It is getting hot out there!!! Have you looked at the temps lately? Spring is breaking down the front door.  As we get further into the planting season we thought it would be a great idea to check in with everyone and fill you in on what we’ve been up to!

Have you seen us this spring? Seth and I have been covering a lot of ground this past month telling everyone about GrowIt!

One of our latest events was the Chicago Flower & Garden Show. We had an awesome time and had the chance to make some new friends. We also had the chance to check out some new plant trends first hand.

Small space gardening was featured in many ways at the show. There were vendors selling small succulent terrariums. There was a whole display of window box gardens. There were even some planter boxes designed to get the most out of the limited space that you might have.

One of the other major themes of the show was children’s gardening. We learned that flower shows aren’t just for your grandmother anymore. The Chicago Flower & Garden Show was loaded with activities for kids. It’s not like they cornered off a jungle-gym and labeled it the “Kids Corner” either; they had multiple gardens where kids could interact and learn. Whether they were planting pansies and learning about bugs, or planting veggies and learning about the benefits of fresh food, there were smiles from ear to ear.

The smells in the building were terrific. There were hyacinths EVERYWHERE. Along with planted hyacinths and even a planted rose garden (yes it was awesome), there was also a large floral presence at the show. Mariano’s sponsored the show and had a fantastic display of cut flowers to be purchased right on the show floor. This way people could take home some color even if the temps weren’t the nicest quite yet. There were also some very interesting “tablescapes” as well. These seemed to blend a wide variety of ideals. It was like a floral type of landscaping, mixing ideas from the garden and the kitchen.

Seth and I also had the chance to talk about what’s coming in the world of gardening. The first thing that we proposed is that since after years of effort, we haven’t been able to come up with a better word to replace gardening, we just have to change the definition. Gardening isn’t just about having a backyard and a massive flower bed. Gardening refers to the act of growing any plant. Are you growing a cactus on your coffee table? Guess what… you are a gardener. Aside from trying to start a “Garden Revolution”, we also talked about how a new wave of technology was sweeping the garden world.

All in all it was a fantastic week and we met a lot of people. Keep an eye out for us this spring as we continue to travel the country spreading the colorful message of GrowIt!

Do You Believe in Magic?!

GrowIt! Co-founder Seth Reed recently had the opportunity to go to Disney World with his family. The plants caught his eye for sure. This is what he had to say:

I’m going to take a wild guess that you’ve probably visited Disney at least once in your lifetime.  If you haven’t had the opportunity yet, you have to put it on your list.  If you have kids, wait till they are about 5, and then take them and their faces will light up in ways you could never have imagined! A few weeks ago I took my family including our 4 year old daughter, and we had a blast.

I’m from the Midwest, and the months of November through February just suck.  The weather is cold, the trees have no leaves, and generally speaking the landscape is kind of dismal – unless you’re one of those people that see 3 feet of snow as a winter wonderland.  Disney World on the other hand is in Orlando, Florida. I should have known better, I guess you could say I was expecting warmer temperatures, but the same grey landscapes. Boy was I wrong! I was pleasantly surprised how green and colorful it was for November.  Below I want to share with you a few ways that Disney makes plants magical…

1. Poinsettias in the landscape – I wasn’t expecting this to be a landscape plant, but it worked fantastically and provided Christmas color everywhere. Much better than how we use it in the Midwest. Poinsettias in large plots look way better than the lonely individual poinsettias we’re used to.

2. Amazing Green Topiarys – ok sometimes having just green creations is a bit boring, but when they are shaped as Disney characters, it brings an area to life! Too Cool!

3. Hanging Baskets – Even with limited options they tend do find something creative to show off.

4. Green is everywhere – everywhere I looked there were trees and plants to help set the mood, and transform the setting into the magical world that they want you to experience.

Perhaps Disney is already aware that plants make people calmer, or that plants provide better oxygen, or that the plant life provides a cooler temperature in the region, or that the shade extends the life of the concrete that it encompasses.  Whatever the reason, it appears that plant life is an integral part of the Disney experience, and that is all part of the magical plan.

I would love to hear comments about your own trips and the plants you saw.

Love Is In The Air… Plant!

At GrowIt! we’re always looking for creative, outside of the box ideas!

Our friends at Plant Jungle have provided us with another fantastic how-to guest blog!

Roses are a traditional Valentine’s day gift, but if your S.O. is not traditional, you may want to get them something that is not as standard as roses. How about a Tillandsia driftwood centerpiece? Or a Tillandsia coral centerpiece? It is the perfect gift for the minimalist plant lover.

Items for customized centerpiece:

*   Waterproof glue
*   Tillandsia
*   Driftwood or dry coral skeleton
*   Lichen
*   Moss
Tillandsia, aka air plant, is quite versatile as it can grow almost anywhere as long as it is in a well-ventilated area. If you want to add moss as an accent, we recommend gluing at a lower area away from the Tillandsia because the moss tends to hold too much moisture which is incompatible with Tillandsia. I solved that conundrum by placing the Tillandsia at the crown or highest point of the driftwood while placing the moss at the bottom. This placement ensures that the excess water will spill from the Tillandsia onto the moss. Therefore, the Tillandsia doesn’t get root rot and the moss gets enough water.

Some things to consider:

*   Soak ocean driftwood prior to gluing the Tillandsia otherwise the salinity may kill the plant
*   Avoid pressure treated driftwood as it may contain copper which is damaging to Tillandsia
*   Reverse osmosis water is best for your plants as it has impurities removed while maintaining trace elements
*   Coral is more compatible with Tillandsia as it is more porous than driftwood. This porosity allows adequate ventilation.
*   When gluing your Tillandsia to driftwood, glue to porous crevices around the crown to allow for water drainage.
*   If your Tillandsia has bloomed, avoid spraying the flower. Just spray the base of the plant.

Caring for your plants:

*   Soak the Tillandsia for 15-20 minutes upon receiving your plant.
*   After the Tillandisa is fully dry, glue and thereafter mist the Tillandsia/moss once or twice a week. In drier climates, you may need to mist the Tillandsia more. Avoid overwatering!
*   If Tillandsia becomes dry, soak for 10-15 minutes
*   Water in the morning as Tillandsia absorbs carbon dioxide at night
*   Lighting: Both the Tillandsia and moss prefer indirect sunlight
*   8-10 drops of water every 2-3 days for lichens

Beside soaking driftwood, this project will take only minutes to complete and will last much longer than flowers!
