Just when you (and I) thought it was safe to plant our tomatoes, we have an extra-late threat of frost – three weeks after our traditional frost date.
Tuesday’s overnight lows are expected to plunge into the mid 30s. With wind chill, it will feel like 32 degrees in Sacramento – and colder in the foothills.
According to the National Weather Service, storm systems later this week will drop snow as low as 3,500 feet on Wednesday night. And we may have more cold, rainy days this week than we had in all of March.
Following days in the 90s just last week, this cold spell will put on the brakes to rapid spring growth – or kill it all together.
So, what’s a poor tomato plant to do? Huddle up with some temporary protection.
Use a plastic milk or water jug as a mini hot house over a new transplant. Cut out the bottom and leave off the cap. This do-it-yourself “hot cap” will protect the transplant from wind chill and frost danger.

In the afternoon, deep water tender plants; that extra moisture keeps the ground warm enough to avoid damage. Also, deep water citrus trees, which are now in bloom.
Another precaution: Make sure to mulch your veggies. Those wood chips or leaves act like a blanket over plant roots, keeping them moist and cozy.
Signs of frost damage are already prevalent in Sacramento gardens, due to some unseasonably cold nights in mid March. That chill killed new sprouts and browned transplants as well as burned tender growth on roses and other shrubs that were pushing out shoots.
When temperatures warm up reliably later this month, trim off the damaged foliage from shrubs. Frost-burned transplants may need to be replaced.
Then, it will be time to plant more tomatoes.

Garden Checklist for week of Nov. 3
November still offers good weather for fall planting:
* If you haven't already, it's time to clean up the remains of summer. Pull faded annuals and vegetables. Prune dead or broken branches from trees.
* Now is the best time to plant most trees and shrubs. This gives them plenty of time for root development before spring growth. They also benefit from fall and winter rains.
* Set out cool-weather annuals such as pansies and snapdragons.
* Lettuce, cabbage and broccoli also can be planted now.
* Plant garlic and onions.
* Keep planting bulbs to spread out your spring bloom. Some possible suggestions: daffodils, crocuses, hyacinths, tulips, anemones and scillas.
* This is also a good time to seed wildflowers and plant such spring bloomers as sweet pea, sweet alyssum and bachelor buttons.
* 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.
* Save dry stalks and seedpods from poppies and coneflowers for fall bouquets and holiday decorating.
* 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.
* Give your azaleas, gardenias and camellias a boost with chelated iron.
* For larger blooms, pinch off some camellia buds.
* Prune non-flowering trees and shrubs while dormant.
* To help prevent leaf curl, apply a copper fungicide spray to peach and nectarine trees after they lose their leaves this month. Leaf curl, which shows up in the spring, is caused by a fungus that winters as spores on the limbs and around the tree in fallen leaves. Sprays are most effective now.
