I'm sure this question would have been asked a 100 times so apologies if I should be searching elsewhere for the answer.
I'm looking to create some hanging baskets this year (having never done so before) but I'm not entirely sure what size plants to buy. I don't know whether I should buy plugs, jumbo plugs, posti plugs, mini plugs, super plugs, hair plugs! You name it! Ideally what I want to do is just place the plant(s) into the pot without having to worry about them dying because I haven't cared for them enough or they only produce a small amount of flowers because I didn't grow them on correctly.
Any help would be great. The plants I am interested in at the moment are Begonias, Petunias & Lobelia.
