Get ready for hot days ahead

Make your plants comfortable with a little TLC now



It’s only the first week of May, but it already feels like summer.

That’s actually pretty normal, according to the National Weather Service. This week last year, Sacramento hit 100 degrees – the first triple-digit day of 2019.

We’re not expected to get that hot this week, although several days in the 90s are forecast. But those 100-degree days are not far away. If we aren’t comfortable, how will our plants handle the summer heat?

Take some time now to help your garden cope with the heat to come. Not only will your plants stay better hydrated, they’ll suffer less disease, too.

Follow this advice from the UC Cooperative Extension master gardeners:

* Deep-water trees and shrubs. This helps build their reserves and trains their roots to go deep.

* Create water basins around trees, shrubs and many summer vegetables such as tomatoes, peppers and eggplant. A basin holds in extra water just a little longer so it slowly seeps into soil. It’s easy to make a basin: Around the plant, build a soil berm about 3 inches high and at least 1 foot from the main stem (for tomatoes) to 6 feet (for trees). But don’t let water stand against trunks or main stems; that can cause crown rot.

* Mulch, mulch, mulch! Put down a layer of insulating organic mulch (leaves, straw, wood chips, etc.) about 3 to 4 inches deep around trees and shrubs as well as any bare areas in the vegetable garden. Leave a circle open around the trunks or main stems of plants (again, this is to avoid crown rot and other issues). Mulch conserves moisture and keeps plant roots comfortable. It also adds nutrients to the soil, protects soil microbes and controls weeds. What’s not to like?

* Check your sprinklers and irrigation system. Now is the time to make adjustments and repairs.

* Water early in the day. This both conserves water and cuts down on fungal diseases.

* One good thing about high heat: It wipes out many fungal disease problems. Powdery mildew disappears as the temperature rises.

Garden Checklist for week of Jan. 12

Once the winds die down, it’s good winter gardening weather with plenty to do:

* 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. (The exceptions are apricot and cherry trees, which are susceptible to a fungus that causes dieback. Save them until summer.) Clean up leaves and debris around the trees to prevent the spread of disease.

* 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.

* After the wind stops, 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 fungicide 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.)

* 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.
