Hi Cassie
Not sure what other people do but I've grown a few Rowans from seed and pretty much leave them to do their own thing with minimal interference. I tend to keep them in the garden in a shady/semi shady spot (i.e. out of direct sunlight and strong winds) and only water them if it's been a while since the last rainfall (talking a week or so). There seems to be different schools of thought on stake size, height, position etc but when they get a bit leggy, I loosely tie them to a small stake about a third of the way up the tree. This provides stability but gives the tree the chance to move a little, which helps to strengthen the trunk. My stakes are generally sized to a third of the height of the tree and angled across the trunk. As I said there are probably many ways to look at this, but this works for me
.
I'm at work at the moment, but I'll dig out a pic when I get home and post it to show one of mine (third generation from seed and about 3 years old).

One on the left no longer needs the stake and is approx. 8 foot high. One on the right is still a bit leggy but is thickening up nicely at the base. Stake detail as explained above and shown below.
and finally ... the Nursery
