Spring starts with rapid warm-up; what does that mean for your garden?
Freesias in bloom herald the beginning of spring, which officially starts Thursday, March 20. Kathy Morrison
How will we remember the Winter of ’25? Was it too wet? Too dry? Just right?
Thanks to “March Miracle” storm systems dumping snow on the Sierra, our Water Year picture looks like it’s found the Goldilocks zone. But Sacramento could still use some more rain this spring.
This winter, Sacramento totaled just above 9.5 inches of precipitation; that’s a little below average. So far, our Water Year (which started Oct. 1) has totaled 13.29 inches in Sacramento; average for that same period is 14.81 inches.
More showers should be expected. Historically, March averages 2.75 inches of rain in Sacramento with another 1.15 inches in April.
Thankfully, the Sierra snowpack looks healthy and local reservoirs are relatively full. Compared to recent drought years, we’re in a good place water-wise heading into the drier months ahead. That’s good new for farmers and gardeners.
In the next few days, dramatic shifts in temperatures could cause some complications, especially for tender seedlings.
According to the National Weather Service, spring will start with a jump in temperatures. Sacramento will go from 61 degrees on March 19 (today, the last official day of winter) to 81 degrees Monday, March 24. That warming trend will start on Saturday and Sunday with a weekend in the 70s before zipping right into the 80s. Make sure new transplants stay hydrated.
(And many of us experienced hail last week!)
Don’t let those warm temperatures fool you; it’s still too early to plant tomatoes. Soil temperature has to rise, too. So far this March, our soil temperature has been trending low.
According to USDA, the average soil temperature on Wednesday in Sacramento County was about 53 degrees F.; that’s more than 3 degrees lower than average for the last day of winter.
Tomato roots need temperatures comfortably in the mid 60s; our soil won’t reach those temperatures until late in April or early May.
Want to plant sooner? Soil in raised beds warms faster. So does soil in black plastic containers; the black plastic absorbs heat. Choose those options for your earliest transplants.

Garden checklist for week of July 19
Remember to water early and deeply; your garden depends on you.
* 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.
* Keep your vegetable garden watered, mulched and weeded. Water before 8 a.m. to reduce the chance of fungal infection and to conserve moisture.
* Water, then fertilize vegetables and blooming annuals, perennials and shrubs to give them a boost.
*Fertilizing flowering plants every other week will extend their bloom. Give vegetable plants bone meal or other fertilizers high in phosphate to stimulate more blooms and fruiting.
* 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.
* If your melons and squash aren’t setting fruit, give the bees a hand. With a small, soft paintbrush, gather some pollen from male flowers, then brush it inside the female flowers, which have a tiny swelling at the base of their petals. (That's the embryo melon or squash.) Within days, that little swelling should start growing.
* 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. New leaves have the best flavor.
* Cut back lavender after flowering to promote a second bloom.
