This will be my 3rd year container gardening, and the first that I'm trying to get big enough containers for my veggies.
I know you need at least 5 gallons to grow just about anything bigger than lettuce, but my problem is: how can you tell how may gallons a container is?
Most planters/containers give you sizes in inches (if at all) and not gallons (or Litres, in Canada-land).
If a standard bucket (the kind you get at the hardware store/leftover from food storage) is 5 gallons, whats a good example of 10? 25?
I got a couple big planters, but have no idea how much they will actually hold.
Photos of examples would be great.
Or, should I dig out the measuring tape and do some basic math?
