High heat can hit even sun-loving crops hard

By Debbie Arrington

Feel the burn? This weekend’s triple-digit spike in temperatures toasts leaves (and people, too).

Make sure to water early in the morning to keep your vegetables hydrated for the hot afternoon to come.

Sun scald of tomatoes, peppers and eggplants is common during these conditions. Erect some temporary shade to shield ripening fruit from intense afternoon sun. (See our 5 hacks for quick shade here.)

These 105-degree days may be enough to push some plants over the top. Determinate tomato varieties – those kinds that grow to a certain height and bear their fruit all at once – may be nearing the end of their cycle. (An example in my garden: Red Pride.) Keep an eye on those vines; they can die back quickly. After harvest, pull out the plant; it likely won’t produce more tomatoes even if green and healthy.

The good news: This heat wave is only temporary. According to the National Weather Service, we’ll quickly slip back into the low 90s for the rest of the week and next weekend. If you can put off chores until then, do it.

What should you concentrate on when you do get outdoors this week?

* Water deeply. Make sure moisture is penetrating soil at least 6 inches and reaching roots.

* Harvest summer squash promptly; it will keep the bush or vines producing.

* Harvest garlic and onions; pull the bulbs before they flower.

* Pick tomatoes, peppers, eggplant and other summer favorites. When temperatures cool, many varieties will set more fruit.

* Pick up and discard dropped fruit around trees; it attracts pests and critters.

* Pinch back chrysanthemums for more blooms in fall.

* Start fall veggies indoors, including cabbage, broccoli and lettuce.

* Outdoors, there’s still time to plant pumpkins, winter squash, corn, beans and sunflowers.
