1. How big is the Stack & Grow when it is assembled?
24" wide and 15" tall. Additional trays can be purchased making it 24" wide and 30" tall.
2. How do the trays stack together?
No tools or additional parts are required for assembly! The trays interlock by lining up pins & holes on each tray. Simple to follow instructions are included with each planter.
3. What is the Stack & Grow made of?
High-quality UV-protected polypropylene plastic. It won't stain your deck or cement walkway like ceramic pots.
4. How high can the Stack & Grow reach?
The planter has been designed to be stacked a maximum of 8 planting trays high. Additional expansion trays must be purchased. No additional hardware needed for stability.
5. Why does one tray have a closed bottom while the other trays are open?
The bottom tray holds the soil while the other open (or "bottomless") trays hold it in, acting as walls. This gives the Stack and Grow a "center" of soil where the roots can expand and thrive.
6. Which plants grow best in the Stack & Grow?
There is a large variety of plants that grow well in the Stack & Grow planter. We recommend 2-4" potted flowers or plants. The Stack & Grow makes a great strawberry garden, lettuce garden, herb garden, or decorative-plant garden.
7. How do I keep plants from over-growing?
Prune, pinch, and deadhead your garden regularly. It will prolong the life of your plants while keeping them looking their best.
8. Will my plants die if I go out of town for a few days?
Water all your stackable planters well and place in a shady location to help plants from drying out while you are away. Lack of sun for a short period of time will not hurt your container garden. The maximum amount of time to leave your planter is 3 to 4 days.
