When to Plant? (Part 1 of 2)
Unpredictable Climate & What It Means for Your Garden
This year has been a wake-up call for gardeners across Utah and the Mountain West. A warm winter with little precipitation led into an early, tempting spring—only to be followed by several hard frosts.
Fruit tree growers, vegetable gardeners, flower enthusiasts, and homeowners alike have felt the impact. Blossoms were lost. Tender seedlings froze. Entire early plantings were wiped out.
At the same time, food prices continue to rise—and many are realizing that growing your own food isn’t just rewarding… it’s becoming essential.
So… When Should You Plant?
In Utah, there’s a long-standing rule of thumb:
👉 Plant warm-season vegetables around Mother’s Day.
This guideline exists for a reason. Historically, it aligns closely with the average last frost date along the Wasatch Front and many populated valleys.
But here’s the reality:
“Average” doesn’t mean guaranteed.
What This Year Teaches Us
Early warmth does NOT mean it’s safe to plant
Late frosts are still very possible—even into May
Microclimates (Utah County vs. Salt Lake vs. higher elevations) matter more than ever
Smarter Planting Strategy (New Approach)
Instead of relying on one date alone:
✔ Watch the 10-day forecast before planting
✔ Use soil temperature (not just air temp)
✔ Start some crops indoors or in protected spaces
✔ Be ready with frost cloth or covers
✔ Stagger plantings (don’t plant everything at once)

Here’s a practical chart to guide your timing:
A Better Way to Protect Your Investment
If you’re planting this season, give yourself an edge.
High-quality soil, proper drainage, and healthy plant starts can make the difference between success and failure—especially in unpredictable years like this.
👉 Local suppliers like Woodstuff Landscape Supply offer:
Garden soil blends designed for Utah conditions
Mulch to regulate soil temperature
Raised bed materials to improve drainage and warmth
Even a simple upgrade in soil quality can significantly increase yields and resilience.
The Bottom Line
Mother’s Day is still your safest baseline
But flexibility and protection are now essential
Gardening success in the Mountain West = timing + preparation + adaptability

A Landscape Shaped by Stone, Story, and the Spirit of the Desert
When you first arrive at Kolene’s home, you quickly realize this garden is unlike any other.
Instead of lush flower beds or carefully planned borders, the landscape unfolds as a winding collection of stones - each one placed with intention, each one carrying its own story. Pathways of rock guide you through the space, leading past agaves, fruit trees, and unexpected treasures gathered from the surrounding desert.
Kolene smiles easily when she talks about it.
“I’m not really a gardener,” she admits with a laugh. “I’m an outdoor person.”
And it shows.
April Tips & Checklist
Plant seeds of cool-season vegetables (peas, lettuce, spinach, radishes) as soon as garden soil is workable.
Check out over 55 vegetable and herb fact sheets produced by USU Extension.
Consider planting peas in the garden every 2-3 weeks (until early May) to extend the harvest.
Control young garden weeds by hoeing or hand-pulling.
Protect fruit blossoms and tender garden plants from late critical freezing temperatures.
If storing bulbs, check to make sure they are firm, and remove any that are soft or rotten.
Wait to prune roses until buds begin to swell to avoid late-frost damage to new growth.
Prune spring flowering shrubs (those that bloom before June) after they have bloomed to encourage new flower buds for next season.
Divide crowded, fall-blooming perennials.
Divide cool-season ornamental grasses when new growth begins to emerge.
Apply chelated iron (FeEDDHA) to plants that have had prior problems with iron chlorosis.
Use organic mulches (wood chips or bark) to retain soil moisture around shrubs and trees.
Plant a tree to celebrate National Arbor Day. The USU Tree Browser offers an interactive list of tree species adapted to the Intermountain West.
Apply pre-emergent herbicides in late March to mid-April to control annual weeds in the lawn, such as crabgrass and spurge.
Learn about lawn care and planting new lawns.
In compacted sites, aerate with a hollow core aerator when turfgrass is actively growing, usually from April to June.
Check your sprinkler system for leaks. Clean filters, and fix and align heads.
Pests and Problems:
Download the Utah Home Orchard Pest Management Guide.
Reduce chemical use to help promote beneficial insects in your landscape.
Treat for coryneum blight in stone fruits (cherries, peaches, nectarines, apricots and plums) at shuck split, approximately 10 days after flower petals drop.
Treat apples for powdery mildew when leaves are emerging (at 1/2 inch green) until June.
Monitor wet weather during bloom in apples, pears, and hawthorns to determine if treatment for fire blight is needed.
Treat fruit trees for cat-facing insects, like stink bugs, to prevent dimples and pucker marks in fruit.
Use preventative controls for peach twig borer in peaches, nectarines, and apricots to help reduce twig and fruit damage later in the season.
Control spring-flying bark beetles in pine trees and other conifers.
Watch for Cutworm damage in turfgrass and new vegetable starts.
