Watch out for leaning trunks and sagging branches

With the downpour on New Year’s Eve, 2022 made up for what had been a very dry year. And 2023 is starting soggy, too.
Record rain had a huge impact on the greater Sacramento area with flooding in south Sacramento County, major power outages and fallen trees all over the place.
According to the National Weather Service, downtown Sacramento received 2.37 inches on New Year’s Eve – a record for that date – and 4.81 inches fell since Christmas. That brought December’s total to 9.5 inches – almost triple the normal (3.49 inches) for that month.
December brought our seasonal total to 10.66 inches since Oct. 1, the start of our “water year.” That total is 148% of normal for that period, which is good news for our reservoirs and drought perspective.
More rain is on the way, says the weather service. Today (Monday) will see a quick-moving storm with less than one-third inch predicted for downtown Sacramento. The real threat comes Wednesday and Thursday; over 48 hours, an estimated 2.5 to 3 inches of rain is expected to fall.
All this moisture puts trees at risk. Be on the lookout for sagging branches and leaning trees.
Water accumulates in the needles of evergreens, stressing limbs with the extra weight. Horizontal limbs are at the greatest risk of breaking. The tree may groan or creak, often a signal that a branch is about to fall – or the whole tree is coming down.
Lawn trees – particularly those affected by drought – are especially susceptible to uprooting; all it takes are strong winds to accompany that moisture. Need proof? On New Year’s Eve, dozens of trees fell in Sacramento neighborhoods, pushed over by 40 mph gusts.
Lawn trees tend to have shallow roots and less of a foothold. If the soil is soggy, those roots give way.
Before the tree falls, there are usually warning signs, such as fissures in the soil around the tree. That’s a sign the roots are pulling loose.
If you see such fissures, stay away from the tree and call a certified arborist immediately. Your tree may be saved with quick action (and support). Never walk under a leaning tree; the soil may be too unstable.

Garden Checklist for week of Nov. 3
November still offers good weather for fall planting:
* If you haven't already, it's time to clean up the remains of summer. Pull faded annuals and vegetables. Prune dead or broken branches from trees.
* Now is the best time to plant most trees and shrubs. This gives them plenty of time for root development before spring growth. They also benefit from fall and winter rains.
* Set out cool-weather annuals such as pansies and snapdragons.
* Lettuce, cabbage and broccoli also can be planted now.
* Plant garlic and onions.
* Keep planting bulbs to spread out your spring bloom. Some possible suggestions: daffodils, crocuses, hyacinths, tulips, anemones and scillas.
* This is also a good time to seed wildflowers and plant such spring bloomers as sweet pea, sweet alyssum and bachelor buttons.
* Rake and compost leaves, but dispose of any diseased plant material. For example, if peach and nectarine trees showed signs of leaf curl this year, clean up under trees and dispose of those leaves instead of composting.
* Save dry stalks and seedpods from poppies and coneflowers for fall bouquets and holiday decorating.
* For holiday blooms indoors, plant paperwhite narcissus bulbs now. Fill a shallow bowl or dish with 2 inches of rocks or pebbles. Place bulbs in the dish with the root end nestled in the rocks. Add water until it just touches the bottom of the bulbs. Place the dish in a sunny window. Add water as needed.
* Give your azaleas, gardenias and camellias a boost with chelated iron.
* For larger blooms, pinch off some camellia buds.
* Prune non-flowering trees and shrubs while dormant.
* To help prevent leaf curl, apply a copper fungicide spray to peach and nectarine trees after they lose their leaves this month. Leaf curl, which shows up in the spring, is caused by a fungus that winters as spores on the limbs and around the tree in fallen leaves. Sprays are most effective now.
