Dig In: Garden checklist for week of Oct. 18

Our Indian (or endless) summer continues with more dry and warm days in the high 80s and low 90s.

According to the National Weather Service, Sacramento will continue with a solid week of above-normal temperatures before cooling slightly – to a high of 81 degrees – on Friday. Nights are warm, too, staying above 56 degrees.

Meanwhile, winds (and fire danger) will die down.

It's time to get things done!

* Now is the best month to plant trees and shrubs in the greater Sacramento area. Need some shade? Plant it now.

* October is also the best month to plant perennials in our area. Add a little well-aged compost and bone meal to the planting hole, but hold off on other fertilizers until spring. Keep the transplants well-watered (but not wet) for the first month as they become settled.

* Now is the time to plant seeds for many flowers directly into the garden, including cornflower, nasturtium, nigella, poppy, portulaca, sweet pea and stock.

Chard is just starting to sprout. Harvest it while very young for microgreens, or just a bit bigger for salads.

* Plant seeds for radishes, bok choy, mustard, spinach, chard 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.

* 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.

* Clean up the summer vegetable garden and compost disease-free foliage.

* Harvest pumpkins and winter squash.

* Pick apples, pears and pomegranates.
