Answer: Trees and shrubs have a better survival rate when transplanted in the spring, fall, or early winter months, mostly to take advantage of the cooler weather and natural rainfall. If you're transplanting your hawthorns this fall, hold off on the fertilizer until next spring when new growth begins. The plants will bud out when the weather prompts them to, so you'll have to take your cue as to when to move them from your weather patterns. You can transplant anytime the ground is not frozen. Wait until after your first frost of the season, but before the first snowfall to move them, to avoid the possibility of their budding prematurely. Crataegus phaenopyrum, Washington Hawthorn, can grow 25'-30' high with a 20'-25' spread so be sure to give each plant plenty of room!
