Can anybody give me any advice on what to do about one of my dwarf Scheffleras being so much farther behind the rest of my Scheffleras in budding out after pruning them this spring? I have 3 of them, two of them are brothers (both came from the same pot), and the other is a Gold Capella variegated Schefflera. The Gold Capella is budding out like crazy and one of my dwarfs is budding out vigorously as well, but the other one isn't. They are all in the same soil mix and they're all watered and fertilized as needed, so I'm at my wits end as to what I'm doing wrong. The only difference between the 2 brother scheffs is that one of them is growing in a bush-shape, and the one I'm having the problems with has been trained into a small tree-shape. Any advice would be much appreciated.
