I've used the small plastic dishes you buy in the store, but they seem to be too short and the water ends up spilling over. Milk cartons are water proof, free and can be cut to any height.
Some of the pots I use for plants are only decorative and not water proof, so I always put in the drainage dishes.
You can use any milk carton...plastic or the wax coated cardboard type.
I bought this silver dish in a thrift store and I just love it for this plant. I don't want to water directly in there just in case I want to you the dish for something else.
The gallon size milk carton is perfect for this.
See the little plastic dish on the bottom? Not great or big enough.
The plastic carton cuts easily with a steak knife.
You can use the bottom half for a drainage dish and the top half, with the spout, for a funnel!!
Just the right size.
Be careful not to leave too much water in the drainage dish or the plant's roots will rot.
The half gallon cartons are great for little plants too!
Here's a picture of another milk carton idea I posted last April...Click HERE to see that post. I cut out some of the carton, but left the handle to thread onto a curtain rod. Lots of storage ideas.
This one is scrap quilt squares...
and these are art supplies...
It's great to use the things we would normally throw away for something useful in our a daily lives. I hope you can recycle too!!
