10 DIY Self-Watering Planters: Easy Household Item Hacks

6. Plastic Food Container Conversion

Who knew those takeout containers could become amazing planters? I started this project during a decluttering phase of my kitchen cabinets, and now I’m actually excited when I have empty containers! These smaller systems are perfect for herbs and microgreens, plus they fit beautifully on any kitchen windowsill.

Choosing the Right Containers

After lots of experimentation, here’s what I’ve learned about container selection:

Best Options:

Large yogurt containers
Clear plastic salad boxes
Rectangular takeout containers
Look for containers with sturdy lids

Container Requirements:

Food-grade plastic (check for recycling numbers 1, 2, or 5)
At least 4 inches deep
Transparent sides are bonus for monitoring water levels

Creating Your Watering System

Here’s my foolproof method:

Reservoir Setup:

Cut lid to fit inside as platform
Create 1/4 inch drainage holes
Leave 1-inch space at bottom

Wicking System:

Cotton rope works best
Thread through platform
Use multiple wicks for larger containers

Perfect Plants for Small Containers

I’ve had amazing success growing:

Herbs:

Basil (my absolute favorite!)
Chives
Cilantro grows surprisingly well

Small Vegetables:

Microgreens
Baby lettuce
Cherry tomatoes (dwarf varieties)
