Greenstalk Garden - Premium Vertical Grow System

So many plants! You can grow a wide variety of vegetables, strawberries, flowers, and herbs in both sizes of the GreenStalk Vertical Planter (Original and Leaf). We recommend growing larger plants in the GreenStalk Original and smaller plants in the GreenStalk Leaf. For a complete list, please see our downloadable plant planner.

Our planters were made for year-round outdoor use. However some gardeners do use them indoors with modifications for lighting and drainage. We are unable to help troubleshoot for indoor gardening at this time. We are hoping to offer solutions for indoor growing in the years to come.

Our planters are made for all climates. They may remain outside year-round or they can be cleaned, stacked, and stored away.

While the GreenStalk is very stable when assembled correctly, like any vertical planter or free-standing object outside, it can fall over if assembled incorrectly or due to high winds. Here are some tips for growing in windy areas:

• Make sure all the pieces are securely locked together and the planter is level after assembly.
• Never place the planter (with or without a base) directly on soil, mulch, or grass.
• If you live in a windy area, we recommend your planter be placed near a structure, tree, deck, or anything that can help shield it from really heavy winds. A planter in an open field is much more susceptible to falling than one near a home and other buildings.
• Make sure your GreenStalk is well watered - water weight is where most of the weight of the planter comes from.
• You may consider stacking down to 4 or 3 Original Tiers to minimize risk and damage.
• If you want to be extra cautious, you can put a rod through the center of the planter and into the ground, but you wouldn't be able to use the watering system. Another option is to place rebar around your planter so that you can still utilize the internal watering system.

We recommend using a paver that is at least 41cm inches by 41cm Make sure it’s placed on solid, even ground to ensure proper stability.

Each individual planted and watered Original Tier weighs approximately 13.6kg. Each individual tier of the Leaf planter weighs approximately 10.5kg.

Each Original Tier holds 0.028 cubic meter of potting mix (about 30 litres). Each Leaf Tier holds 0.021 cubic meters of potting mix (about 22 litres).

Any high quality, lightweight potting mix would work well. Avoid using topsoil, raised bed soil, or garden soil.

Watering needs vary depending on time of year, weather, and the variety of plants. Upon initial set-up of the planter, we recommend completely soaking the soil by way of the water reservoir and individual pockets. When planting seeds, water with a mister until the plants are established, so as to not displace the seeds. Always check to see if the soil is moist underneath the top layer.

GreenStalk's patented slow drip watering system allows water to drain through the system within approximately 5 minutes. If used correctly, there will be no sitting water anywhere in the system. The bottom of the GreenStalk includes little “feet” that allow water to drain out and away from the planter.

You can add granular fertilizers, compost or worm castings when filling the tiers with soil. You may also add water soluble fertilizer as needed through the GreenStalk’s internal watering system when filling the top water reservoir.
