I've brought few tomato plants from home depot (Bonnie brand) and they are 5 to 8 inches tall and their roots start poking out from the bottom (and sides) of their (3" and 4") containers.
Seems like time to plant them in bigger pots. My question is, should i plant then straight into 20" pots, or should i choose smaller intermediate container? The reason i'm asking, besides for lack of experience (first time gardener here), is that in this video plant tomato deep, for example, suggests deep planting of tomatoes, where the guy trims all the leaves besides for the very top. If my entire plant is 5" tall, "deep planting" would not work.
I'd love to post an image to illustrate but StackExcahnge tells me I need 10 Reputation.
Appreciate your help.
