Frequently Asked Questions (FAQs)

1. Are resin planters durable?

Resin and Plastic Planters Plastic and resin planters have the unique ability to mimic other materials, such as stone, concrete, and terra cotta, but are much more lightweight, durable, and versatile than many natural materials which may crumble or crack.

2. Are resin planters good?

Resin's durability and lightweight make it an excellent choice for both indoor and outdoor planters while requiring a lot less maintenance than other materials such as terracotta or wood.

3. Do window boxes cause rot?

Make sure your window box has proper drainage. Improper drainage can cause your window box to rot faster. Wooden boxes may last for several years, but they will eventually rot. If you notice that your window box has boards that are separating or wood that feels soft to the touch it is time to replace your box.

4. Do window boxes need drainage?

It's absolutely necessary that a window box have drainage holes so plants do not sit in soggy soil. If your box does not come with holes, you will need to drill holes in the bottom before installation.
