Watch out for leaning trees and cracked soil

How much rain did you get? Chances are – a lot!
Sacramento’s first atmospheric river of the 2023-24 rainy season gave our region a good, deep soaking. Starting Sunday night through Tuesday midnight, Downtown Sacramento recorded 2.61 inches, according to the National Weather Service. That includes a record 1.6 inches on Tuesday, Dec. 19.
Other parts of the greater Sacramento area received more – or less. Here in the Pocket/Greenhaven neighborhood, my rain gauge collected just under 4 inches. That includes some showers from Wednesday morning.
Meanwhile, Davis recorded only 1.24 inches since Sunday, says the weather service.
Rain totals from the thunderstorms that blew across our region Tuesday afternoon illustrate the hit-or-miss tendency of this storm system. Sacramento Executive Airport recorded 1.55 inches in the 24-hour period of 4 a.m. Tuesday-Wednesday, according to the California Nevada River Forecast Center, a part of the National Oceanic and Atmospheric Administration. For that same period, Elk Grove received only 0.16 inches.
Also for that same 24 hours, Sacramento State’s rain gauge recorded 1.06 inches while the gauge at Arcade Creek-Winding Way in Carmichael received only 0.39.
While much of Sacramento was getting drenched Tuesday, Roseville, Fair Oaks, Rocklin, Orangevale, Lincoln and Rancho Cordova all recorded less than one-third inch.
A lot of rain in a hurry not only leads to possible flooding; it can destabilize trees – especially if followed by strong gusts of wind.
After the rain stops, take a look around your landscape. If you notice a tree leaning or cracks in the lawn or soil around a tree or large shrub, call an arborist. Those cracks are caused by roots being pulled out of place. You may need expert help to keep that tree upright.
Also be careful walking on wet soil; it can compact easily, squeezing out the vital air pockets needed by roots and microorganisms.

Garden Checklist for week of Jan. 19
Dress warmly in layers – and get to work:
* Apply horticultural oil to fruit trees to control scale, mites and aphids. Oils need 24 hours of dry weather after application to be effective.
* This is also the time to spray a copper-based oil to peach and nectarine trees to fight leaf curl. The safest effective fungicides available for backyard trees are copper soap -- aka copper octanoate -- or copper ammonium, a fixed copper fungicide. Apply either of these copper products with 1% horticultural oil to increase effectiveness.
* Prune, prune, prune. Now is the time to cut back most deciduous trees and shrubs. The exceptions are spring-flowering shrubs such as lilacs.
* Now is the time to prune fruit trees. Clean up leaves and debris around the trees to prevent the spread of disease. (The exceptions are apricot and cherry trees, which are susceptible to a fungus that causes dieback if pruned now. Save those until summer.)
* Prune roses, even if they’re still trying to bloom. Strip off any remaining leaves, so the bush will be able to put out new growth in early spring.
* Clean up leaves and debris around your newly pruned roses and shrubs. Put down fresh mulch or bark to keep roots cozy.
* When forced bulbs sprout, move them to a cool, bright window. Give them a quarter turn each day so the stems will grow straight.
* Browse through seed catalogs and start making plans for spring and summer.
* Divide daylilies, Shasta daisies and other perennials.
* Cut back and divide chrysanthemums.
* Plant bare-root roses, trees and shrubs.
* Transplant pansies, violas, calendulas, English daisies, snapdragons and fairy primroses.
* In the vegetable garden, plant fava beans, head lettuce, mustard, onion sets, radicchio and radishes.
* Plant bare-root asparagus and root divisions of rhubarb.
* In the bulb department, plant callas, anemones, ranunculus and gladioli for bloom from late spring into summer.
* Plant blooming azaleas, camellias and rhododendrons. If you’re shopping for these beautiful landscape plants, you can now find them in full flower at local nurseries.
