New month brings new season (and more heat)

September a busy time in Sacramento gardens

After a summer filled with extremes, it’s hard to remember: What’s “normal”?

For the waning days of summer, cooler temperatures usually prevail. September’s average high in Sacramento is 87 degrees; it’s 90 degrees for this first week.

So, these first days of September are actually almost normal, temperature-wise.

But nothing has been “average” about 2020 – and that includes this Labor Day weekend. The National Weather Service is forecasting another extreme heat warning with possible record highs over the coming three-day holiday. The all-time hottest September day on record in Sacramento: 108.

Hopefully, this is just another spike and not some “new normal.”

Transitioning from summer into fall, September is one of the busiest months in the Sacramento garden. It starts another season in the vegetable garden.

Summer veggie plants that are healthy and producing can stay in place. But don’t expect tomatoes to set any more fruit during this coming heat. If your tomato plants have no green fruit, it may be a good time to pull those vines.

Compost the old and prepare for the new. Cultivate the soil and replenish its nutrients, adding aged manure or finished compost. Cool-season leafy green crops need their nitrogen.

After this Labor Day heat wave, start transplanting cool-season favorites such as cabbage, broccoli, Brussels sprouts, cauliflower, kale and head lettuce.

Onion sets can be planted now as well as potatoes. From seed, plant leaf lettuce, peas, radishes, turnips, beets, carrots, bok choy and spinach directly into the vegetable beds.

The warm soil will get these veggies off to a fast start.

Before this summer becomes a distant memory, take a few minutes now to evaluate your harvest. Which tomato and pepper varieties did well? Which ones were flops? What would you do differently if you could plant again?

Make notes to yourself – including one to follow through on your own advice next year.

We’d like to hear about your garden successes (and not-so-great results, too). Send photos and observations; we’ll compile them into a garden report card for the Sacramento summer of 2020.

Garden checklist for week of July 12

Get out early in the morning to take care of garden chores. Temperatures are expected to stay below 80 degrees before 10 a.m.

* Remember to water early and deep; your garden depends on you.

* It’s not too late to add a splash of color. Plant petunias, snapdragons, zinnias and marigolds.

* From seed, plant corn, pumpkins, radishes, winter squash and sunflowers.

* Keep your vegetable garden watered, mulched and weeded. Water before 8 a.m. to reduce the chance of fungal infection and to conserve moisture.

* Water before fertilizing vegetables and blooming annuals, perennials and shrubs to give them a boost. Feeding flowering plants every other week will extend their bloom.

* Feed vegetable plants bone meal or other fertilizers high in phosphate to stimulate more blooms and fruiting.

* Don’t let tomatoes wilt or dry out completely. Give tomatoes a deep watering two to three times a week. Harvest vegetables promptly to encourage plants to produce more. Squash especially tends to grow rapidly in hot weather. Keep an eye on zucchini.

* If your melons and squash aren’t setting fruit, give the bees a hand. With a small, soft paintbrush, gather some pollen from male flowers, then brush it inside the female flowers, which have a tiny swelling at the base of their petals. (That's the embryo melon or squash.) Within days, that little swelling should start growing.

* Pinch back chrysanthemums for bushy plants and more flowers in September.

* Remove spent flowers from roses, daylilies and other bloomers as they finish flowering.

* Pinch off blooms from basil so the plant will grow more leaves.

* Cut back lavender after flowering to promote a second bloom.
