Record heat zaps end of summer garden; time to focus on fall
It's harvest time for gourds, pumpkins and winter squashes. Kathy Morrison
OK, we usually get some warm days in October, but this was ridiculous.
This month started red-hot with a three-day streak of triple-digit days – more than 20 degrees above normal. Thursday (Oct. 3) hit 103 at the observation site near Sacramento State University – a record for the hottest October day ever in Sacramento. National Weather Service records date back to 1877 – almost 150 years.
According to the weather service, our hot streak isn’t over yet; another 100-degree day is forecast for Sunday – thanks in part to unusually warm overnight lows. Instead of dipping down into the 50s, nighttime temperatures will barely go below 70 degrees. That starts days warm, and they heat up rapidly from there.
Fortunately, we’re finally going to cool down soon. The weather service forecasts more typical October days in the low to mid 80s and nights in the 50s by Wednesday. Next week, we should start seeing something that resembles fall.
What does this mean for our gardens? Expect fall color to be delayed; foliage needs chilly nights to bring out the reds and golds.
That heat likely zapped the last remnants of our summer gardens; it’s time to pull the tomatoes, if you haven’t already.
On the positive side, warm soil is great for planting. Get ready to get to work!
* Clean up the summer vegetable garden and compost disease-free foliage.
* Harvest pumpkins and winter squash.
* October is the best month to plant trees, shrubs and perennials.
* Before planting, add a little well-aged compost and bone meal to the soil, but hold off on other fertilizers until spring. Keep the transplants well-watered (but not wet) for the first month as they become settled.
* Dig up corms and tubers of gladioli, dahlias and tuberous begonias after the foliage dies. Clean and store in a cool, dry place.
* Treat azaleas, gardenias and camellias with chelated iron if leaves are yellowing between the veins.
* Now is the time to plant seeds for many flowers directly into the garden, including cornflower, nasturtium, nigella, poppy, portulaca, sweet pea and stock.
* Plant seeds for radishes, bok choy, mustard, spinach and peas.
* Plant garlic and onions.
* Set out cool-weather bedding plants, including calendula, pansy, snapdragon, primrose and viola.
* Reseed and feed the lawn. Work on bare spots.

Garden checklist for week of Jan. 18
Make the most of these rain-free breaks. Your garden needs you!
* 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.
* Plant bare-root roses and fruit trees.
* In the bulb department, plant callas, anemones, ranunculus and gladiolus for bloom from late spring into summer.
* Browse through seed catalogs and start making plans for spring and summer.
* 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, except cherry and apricot trees. 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.
* Prune Christmas camellias (Camellia sasanqua), the early-flowering varieties, after their bloom. They don’t need much, but selective pruning can promote bushiness, upright growth and more bloom next winter. Give them an acid-type fertilizer. But don’t fertilize your Japonica camellias until after they finish blooming next month. Doing that while camellias are in bloom may cause them to drop unopened buds.
* Clean up leaves and debris around your newly pruned roses and shrubs. Put down fresh mulch or bark to keep roots cozy.
* Divide daylilies, Shasta daisies and other perennials.
* Cut back and divide chrysanthemums.
