Q.fertilizing dormant dwarf fruit trees
Should I plant my dormant dwarf fruit trees in soil with fertilizer? I ordered 4 dwarf fruit trees (a Methley plum, a Reliance peach, an Asian persimmon, and a sweet cherry tree). They will arrive in November.

You can apply a fertilizer that is higher in phosphorous and potassium and lower in nitrogen in a slow release formula.
This will help promote good root growth and winter hardiness.
Less is more as excess fertilizer can be a stressor at planting time, so do not over-apply.
Watering is very important to get the new plantings established.
