Frequently Asked Questions

GreenStalk Information

What can I grow in the GreenStalk Vertical Planter?

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 planting guide here.

Can the GreenStalk Vertical Planter be used indoors? 

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.

Can I download a copy of the Vertical Planter Instructions? 

Yes! You can download a PDF of the Vertical Planter Instructions here.

Is the GreenStalk Vertical Planter patented? 

Yes! We have been issued both a design and utility patent. There's nothing else like the GreenStalk Vertical Planter on the market.

How do I store my GreenStalk Vertical Planter during the winter months? 

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

How much does each tier weigh?

Each individual planted and watered Original Tier weighs approximately 30 lbs. Each individual tier of the Leaf planter weighs approximately 23 lbs.

How much soil do I need?

Each Original Tier holds 1 cubic foot of potting mix (about 8 gallons). Each Leaf Tier holds 0.75 cubic feet of potting mix (about 6 gallons).

Do I need special soil to use GreenStalk?

The GreenStalk team's favorites are Fox Farm, Espoma, and Pro-Mix brands. However, any high-quality, lightweight potting mix would work well. Avoid using topsoil, raised bed soil, or garden soil.

How often should I water my plants?

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. 

How long does the water sit in the reservoir? 

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.

How do I fertilize my GreenStalk Garden?

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.
