Plant soil is not cheap!
Especially if you like to have a beautiful flower garden.
And it's even worse with a large flower pot, because you need a lot of potting soil to fill it.
Fortunately, there is a trick to save potting soil in flower pots.
The trick is to bury plastic canisters in the bottom of the pots:
1. Take empty plastic canisters.
2. Close the bottle caps.
3. Place them in the bottom of your flowerpot.
4. Cover the containers with potting soil.
There you go, you've saved a lot of potting soil in the flowerpot :-)
If you don't have a canister, you can of course use plastic bottles.
If you don't have potting soil for your plants, you can find some here.
