Q.Recycling yogurt pots into flower pots
I have a supply of 1Kg yogurt pots and was thinking of using them as flower pots. The pots are 12cm top diameter with 12cm depth. How many holes of what diameter to provide drainage should I provide in them?

There is no certain amount or diameter of the hole. Just be sure that they are a few cm apart from each other. The potting mix should be light and provide most of the drainage. The holes will allow water to flow out of the container. With the right mix, as little as two holes will allow for proper drainage, although I would recommend more than that. Some containers I see have their holes not on the bottom of the pot, but on the lower sides. This helps facilitate drainage in my opinion.
