I've been looking into container gardening for vegetables and I'm trying to make sense of container sizes. Several books refer to a barrel or half-barrel but I haven't seen anything labeled "barrel" and the store.
With vegetables is the volume of the pot more important or the depth?
For tomatos I've been told I can use an 8 in deep window box. Another source said a 10 or 12 inch diameter pot should be fine. Someone else said to plant 3 tomatos in a huge 24 inch diameter pot. I'm so confused about how big a container I really need. I just can't seem to find any consensus on what size pots I need for tomatos (or peppers or peas or radishes for that matter). I don't want to use something too small, but the thought of the cost for all the soil required for 6 or 7 of the 24" diameter pots is scary
I'm curious as to what y'all have used before and what results you got.
