Quick help for plants in danger of sunburn

Venture outside in this heat without a hat and sunscreen, and you know what you'll get: Sunburned skin.
Pity your plants, which can't don sun-protective gear or move into the shade. Yet they get sunburned, too.
Sunscald mars ripening tomatoes and peppers. Even melons get scorched in intense heat.
Here's the deal: Growing something that requires "full sun" doesn't always mean, in our climate, "full exposure to sun." Full heat may require some filtered afternoon shade.

The experienced gardeners in my community garden have learned this. Some grow tomatoes under a wooden superstructure that shades the plants. Others hang shade cloth or frost cloth across the front of their tomato plants. A few have a sea of lace tablecloths floating on stakes over their veggies, giving the garden a refined air.
Frankly, I've given up trying to grow bell peppers and certain tomato varieties in full sun. My Robeson tomato, which does not like intense heat, is doing quite nicely this year in a large pot on the north side of a backyard crape myrtle tree. The peppers are also in pots, cozying up against rose bushes and dwarf citrus trees, which give just enough shade.
Are you seeing sunscald on your developing produce? Here are 5 hacks you can try now with items in your home or garden. Since they're not permanent solutions, be sure to plan for 2020: It's going to be just as hot next year.

1) Use black plastic plant flats balanced on top of tomato cages. They fit, I found out in desperation one summer. Use them alone or to anchor a piece of burlap or shade cloth to protect peppers or small tomato plants.
2) Put paper hats on melons. Use junk mail envelopes (plain ones, not the ones with the windows) as quick paper hats or cones over your most-exposed little melons. Or fold a piece of newspaper into a tent for a larger melon.
3) Newspaper sections also work as quick, desperation shade, hanging off tomato cages and cucumber trellises. Light can't get through it at all, however, so replace it soon with something less opaque.
4) Are the plants growing up a fence or trellis? Use clothes pins to attach thin dishtowels (worn ones work best) to the trellis, hanging them over the veggies. This is good for cucumbers or any other climbing vegetables.
5) Bring tree shade to the veggies: Trim off just a foot or so of a thin leaf-filled branch from an ornamental tree and lay it carefully among ground-growing veggies, such as squash or melons. The leaves will filter the sun just enough.

Garden checklist for week of Nov. 30
It's going to get colder after the fog (finally) dissipates. Without the fog, damp ground will finally have a chance to dry out – and no rain is in the forecast for at least a week.
Make the most of this break in the weather and tackle late fall chores:
* Protect tender plants from possible frost damage. Don’t leave poinsettias outdoors.
* Rake and compost leaves, but dispose of any diseased plant material. For example, if peach and nectarine trees showed signs of leaf curl this year, clean up under trees and dispose of those leaves instead of composting.
* Clear gutters and storm drains.
* Prune dead or broken branches from trees.
* For holiday blooms indoors, plant paperwhite narcissus bulbs now. Fill a shallow bowl or dish with 2 inches of rocks or pebbles. Place bulbs in the dish with the root end nestled in the rocks. Add water until it just touches the bottom of the bulbs. Place the dish in a sunny window. Add water as needed.
* Plant bulbs at two-week intervals to spread out your spring bloom. Some possible suggestions: daffodils, crocuses, hyacinths, tulips, anemones and scillas.
* Seed wildflowers and plant such spring bloomers as sweet pea, sweet alyssum and bachelor buttons.
* Set out cool-weather annuals such as pansies and snapdragons.
* Lettuce, cabbage and broccoli also can be planted now.
* Plant garlic and onions.
* Give your azaleas, gardenias and camellias a boost with chelated iron.
* For larger blooms, pinch off some camellia buds.
