Hi guys, i'm going to be ordering some plants in the next couple of days but i am slightly wary of receiving them through the post. Almost all of the plants i want to use are available in the Tropica 1-2 range so i am going to be using these almost exclusively. Due to the nature of these plants are they better suited to being sent out mail order than normal potted plants? Also how quickly do these need to be planted to get the best results? Thanks in advance.
