How to Fertilize When Using Plant Straws?

Q: Can I add fertilizer to the water container?
A: We don’t recommend it. Liquid fertilizers aren’t designed to be given in small amounts over time, and exposure to light can cause bacteria and germs to build up in the vase.

Instead, try this:

1. Flush the soil with clean water until it drains out. This helps prevent root burn.
2. Let the plant drip dry, then apply your fertilizer as directed (typically 1–2 times per month).
3. For a longer-term solution, mix a slow-release fertilizer into the soil.

You don’t need to remove the Plant Straws from the soil to fertilize your plants.
