Solutions to Common Problems
How can I fertilize my vertical garden?
Adding liquid fertilizer by hand is a great way to fertilize. You can also use plant food spikes that slowly dissolve just beneath the drippers at the top. If you use two drippers per pocket you can place the plant food spikes in the void at each side of the top planted pocket.

What is the best type of fertilizer to use?
We like to use organic fertilizers as well such as Maxsea which is a urea based fertilizer with seaweed as a micronutrient component.
For indoor walls, which are exposed to air conditioners almost all year round. What would you advise is the best watering schedule for the plants?
Water timing varies drastically with each install. Testing and careful observation is required throughout the life of the wall to adjust to varying conditions and plant types. Water schedules can be anywhere from one hour 4 times a day to 3 hours once a week. Typically start with 30 minutes twice daily then adjust accordingly.
Do I need to change the soil?
We do not recommend to change soil. The system will slowly revert to a hydroponic condition. However if you use organic fertilizers you can maintain active soil biology.
Why are some plants dry and others getting water?
A single irrigation line at the top is typically required. You will notice each bottom fold of each pocket will become moist. Therefore it is required that you wrap each plant long and flat so it will touch the very bottom of each pocket. Also if you use a lot of peat with your plantings the soil will become hydrophobic meaning it will repel water when it becomes dry.
To prevent plant dry-outs:
- Make sure the wrapped plant is touching the bottom fold of each pocket.
- Use a soil mix that will easily absorb water.
- Hand water dry plants daily with a hose and sprayer until the soil mixture has decayed enough to conduct moisture.
- Run the irrigation more frequently and for longer periods at the beginning to get the moisture flowing properly throughout the system.
What is the best way to plant my vertical garden?
For a fully filled planting use 6 inch potted materials with some soil removed. It's much easier however to use two 4 inch potted plants per pocket. These will quickly grow in and the smaller plant materials are more suited to adapt. Simply lay the 4 inch materials in the root wrap and fold per our method.
Why are there white deposits on my vertical garden?
White deposits are caused by lime or other minerals in your water. This will also cause the pH to become very high. Plants will not be able to take up nutrients in these conditions. To resolve this you should consider using a reverse osmosis carbon based filter to clarify your water source. To remove existing deposits use distilled white vinegar in a spray bottle to dissolve the white deposits. The acidic vinegar will also lower the pH in your system.
