Winter tree trimming in Diamond Springs
Winter is the main pruning season for a lot of trees. Leaves are off, so you can see the shape of the tree.
Oaks that drop their leaves get pruned now, says a UC Master Gardener talk for El Dorado County. Most fruit trees too. A UC Master Gardener sheet says winter pruning shapes young fruit trees and gets them growing.
Winter is also mistletoe season. With the oaks bare, the clumps are easy to spot. Cut them before they set berries.
Grapes like to wait. UC says pushing grape pruning late into the dormant season, February or later, cuts the risk of Eutypa infection.
Spring
Spring is mostly a time to watch, not cut. The arborist group says growth and healing are best when pruning happens before the spring flush of leaves. But heavy cuts right after that flush are a bad idea, since the tree just used up its energy making leaves.
Pines are off limits now too. UC says not to prune them from February to mid-October, when bark beetles are flying. Elms have a similar rule from March to September.
Keep an eye on fruit trees in spring. Leaves that fade, stay small or wilt on one branch can mean Eutypa dieback, UC says.
Summer tree trimming in Diamond Springs
Summer is apricot and cherry time. UC says to prune them only in July and August in inland areas. The cuts close up before the rains come back.
Evergreen oaks, like interior live oak and canyon oak, get their trim in summer too.
A light summer trim on other fruit trees helps keep them short. The Master Gardener sheet says summer pruning controls growth.
Keep an eye up during hot, still afternoons. Big oaks sometimes drop a sideways limb with no wind at all. It's called summer branch drop.
Fall
Fall is planning time. Note which limbs bugged you all summer. Book early if you want a winter visit.
Mid-October opens the window for pines again. And once the rains start, UC's fire checklist says it's a better time to spread fresh mulch. Mulch put down after fall rain has time to settle and burns less easily.
Fall is also when the rains bring Eutypa spores back. That's why apricots and cherries should be done by then.
One more thing
A calendar is a guide, not a law. A pro who sees your tree might pick a different week for a good reason. Ask them why. A good one will tell you.
