Hi DM,
I have a drawf peach tree already which bloomed and now bearing the beginnings of fruit. It's my first peach tree, so I don't have any experience to mention. However, I did give it a fairly large fertilizer stake earlier in the season. I plan on staking it every year. Oh, and I water my container every other day. I'm sure once the temps increase, it will need water daily.
Hope that helps in some way.
