Those April showers will help May flowers. You’ll see the proof very soon.
Recent precipitation refreshed our gardens, but it was only a sip. Keep an eye on your soil moisture as temperatures spike back up. New seedlings could easily wilt.
According to the National Weather Service, Sacramento could see 90 degrees on Wednesday. Before and after that peak, our afternoon highs should be in the low 80s, just above average. Normal for the first week of May: 80 degrees.
Our “rainy” season is just about over; May averages 0.68 inches of rain. (If that materializes, we’ll take it.) In the meantime, keep new transplants watered. Slow and deep irrigation will encourage strong roots and better drought resistance during dry times ahead.
After planting, apply a layer of organic mulch (leaves, bark, straw, etc.) to help retain moisture.
* Plant, plant, plant! May is prime planting season in the Sacramento area. Time to set out those tomato transplants along with peppers and eggplants. Pinch off any flowers on new transplants to make them concentrate on establishing roots instead of setting premature fruit.
* Direct-seed melons, cucumbers, summer squash, corn, radishes, pumpkins and annual herbs such as basil.
* Harvest cabbage, lettuce, peas and green onions.
* In the flower garden, direct-seed sunflowers, cosmos, salvia, zinnias, marigolds, celosia and asters. (You also can transplant seedlings for many of the same flowers.)
* Plant dahlia tubers. Other perennials to set out include verbena, coreopsis, coneflower and astilbe.
* Transplant petunias, marigolds and perennial flowers such as astilbe, columbine, coneflowers, coreopsis, dahlias, rudbeckia and verbena.
* Keep an eye out for slugs, snails, earwigs and aphids that want to dine on tender new growth.
* Feed summer bloomers with a balanced fertilizer.
* For continued bloom, cut off spent flowers on roses as well as other flowering plants.
* As spring-flowering shrubs finish blooming, give them a little pruning to shape them, removing old and dead wood. Lightly trim azaleas, fuchsias and marguerites for bushier plants.

Garden Checklist for week of Feb. 9
Be careful walking or working in wet soil; it compacts easily.
* Keep the irrigation turned off; the ground is plenty wet with more rain on the way.
* February serves as a wake-up call to gardeners. This month, you can transplant or direct-seed several flowers, including snapdragon, candytuft, lilies, astilbe, larkspur, Shasta and painted daisies, stocks, bleeding heart and coral bells.
* In the vegetable garden, plant Jerusalem artichoke tubers, and strawberry and rhubarb roots.
* Transplant cabbage and its close cousins – broccoli, kale and cauliflower – as well as lettuce (both loose leaf and head).
* Indoors, start peppers, tomatoes and eggplant from seed.
* Plant artichokes, asparagus and horseradish from root divisions.
* Plant potatoes from tubers and onions from sets (small bulbs). The onions will sprout quickly and can be used as green onions in March.
* From seed, plant beets, chard, lettuce, mustard, peas, radishes and turnips.
* Annuals are showing up in nurseries, but wait until the weather warms up a bit before planting. Instead, set out flowering perennials such as columbine and delphinium.
* Plant summer-flowering bulbs including cannas, calla lilies and gladiolus.
