Dig In: Garden checklist for week of Aug. 25


In hot weather, harvest crops daily. Tomatoes and other vegetables can
ripen rapidly. The plants also may need some shade to prevent sunburn.

Are your plants ready for more triple-digit weather?



Hot! That's the forecast from the National Weather Service as Sacramento faces at least five consecutive days of triple-digit temperatures.

The upper range for the Central Valley is predicted between 98 and 107 degrees for Tuesday, the peak of this heat wave. Keeping us warm, overnight lows are hovering around 70.

Stay hydrated. That goes for you and your garden. Irrigate early in the morning or evening. Try to limit your garden activities to the cooler parts of the day.

Put off major chores and planting until the weather cools back down into the low and mid 90s, the current forecast for next weekend. (Remember: It's not lazy, it's smart.)

What to do while you can:
* Test soil moisture. Use a moisture meter or just a long-handled screwdriver. If it can't penetrate 6 inches, that hard soil is too dry. Deep water where needed.

* Harvest daily. Crops can ripen rapidly in hot weather and quickly go over the top.

* Got watermelons? As they near ripeness, cut back on water for the last two weeks or they may split. Look at the little curly tendril growing opposite the melon on the vine. If it's green and springy, the melon is still growing, so keep watering. If it's yellow, cut back on irrigation. If the tendril is brown, the melon is at full size and ripe.

* Shade ripening tomatoes, eggplant and peppers; they can easily sunburn in this weather.

* Skip the fertilizer this week; it may cause more plant stress than good.

* Check on new transplants; are they getting enough water? Do they need temporary shade?

* Let the lawn grow (if it's growing at all). Longer grass conserves moisture.

* Pick up fallen fruit; it attracts all sorts of pests.

Garden Checklist for week of July 21

Your garden needs you!

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

* Feed vegetable plants bone meal, rock phosphate or other fertilizers high in phosphate to stimulate more blooms and fruiting. (But wait until daily high temperatures drop out of the 100s.)

* 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.

* 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.

* 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.
