Wasatch County, UT — Planting Guide
What to do in July
If you only do a handful of things in the garden this July, make it these. They're sequenced around your zone's frost timing.
-
Begin indoor sowing: basil, peppers, and pole beans
You're about 11 weeks out from your last frost — the perfect window to get these germinating indoors.
-
Basket week: basil, carrots, and cucumber
Don't tug. Use scissors or pruners for clean cuts — torn stems invite disease.
-
Kick off the fall garden with carrots, kale, and lettuce
Mid-season soil is hot. Sow a bit deeper than the packet suggests to find cooler, damper ground.
To set up a strong August, finish these tasks
- First harvests: basil, carrots, and cucumber
- Fall sowing: alliums, bachelor's button, and crocus

Monthly Watering Calendar for Wasatch County
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
What this means for you: Mulch reduces watering needs 30-50% by cutting evaporation. Wasatch County's 17" annual rainfall might be enough for vegetables in some months and not in others — a 2-3" mulch layer evens the swing.

Frost Risk Probability
Based on 31 years of NOAA weather station data from 3 stations
Beginners: Plant frost-sensitive crops (tomatoes, peppers, squash) after the "Safe" date on the left. Harvest or cover them before the "Protect by" date on the right. Hardy crops (lettuce, peas, kale) can go in the yellow transition zones.
How to read this table: "Conservative" means you're safe from frost 9 out of 10 years — best for beginners and frost-sensitive crops. "Average year" is the typical date. "Aggressive" means only 1 in 10 years is that warm — experienced gardeners with frost protection can try these dates.
| Planting Strategy | Last Spring Frost | First Fall Frost | Frost-Free Days |
|---|---|---|---|
| Conservative (safest) | Jun 19 | Oct 18 | 121 days |
| Cautious | Jun 7 | Oct 6 | 121 days |
| Average year | May 19 | Sep 26 | 130 days |
| Optimistic | May 4 | Sep 20 | 139 days |
| Aggressive (risky) | Apr 23 | Sep 9 | 139 days |
Not very — frost dates can vary by ±57 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.

Sunlight & Day Length in Wasatch County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
Quick context: Lettuce and cilantro "bolt" (go to seed) when days lengthen. Knowing your day-length curve helps you time spring plantings to harvest before the bolting trigger hits. Wasatch County's daylight ranges shape the planting calendar.

Peak Sun Hours
10.9 hr/day peak (summer)
Peak sun hours (green dashed line below) account for cloud cover — this is the usable direct sunlight your garden actually receives. Most vegetables need 6+ peak sun hours.
Onion tip: Your long summer days (14+ hours) support long-day onion varieties like Walla Walla, Sweet Spanish, and Ailsa Craig.

Soil Temperature & Composting in Wasatch County
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
What this means for you: Lettuce germinates at 35°F. Beans want 60°F. Tomatoes 65°F+. Soil temp, not air temp, is what plants feel. Wasatch County's monthly curve tells you when each crop actually has the conditions to take off.
Plant Warm Crops When
Soil reaches 60°F+
Soil rarely reaches 60°F — use black plastic mulch to warm soil.
Best Month to Compost
Jul
Microbial activity peaks when soil is warm.
Active Composting
2 months
Short season — insulate pile or use indoor vermicomposting.

Pest & Disease Pressure in Wasatch County
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
Why it matters: Pest pressure is a function of climate, not effort. Wasatch County's baseline tells you how much vigilance is normal. A bad pest year in low-pressure region = a normal year in high-pressure region.
Insect Pest Pressure
Moderate — common pests appear but manageable with monitoring.
Disease Risk
Low disease risk — dry conditions reduce fungal problems.
Seasonal Risk
View 5 common pests in your area
| Pest | Risk Level | Peak Months |
|---|---|---|
| Aphids | Moderate | May, Jun, Jul, Aug |
| Japanese beetles | Moderate | Jun, Jul, Aug |
| Squash bugs | Moderate | Jun, Jul, Aug |
| Tomato hornworms | Moderate | Jul, Aug |
| Cabbage loopers | Low | May, Jun, Jul, Aug |
Organic pest management tips
- Maintain healthy soil with regular compost additions to build natural pest resistance
- Practice crop rotation annually to break pest cycles
- Encourage beneficial insects with flowering herbs like dill, fennel, and yarrow
Cover Crops for Wasatch County
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
For new gardeners: Cover crops do four things at once: fix nitrogen (legumes), suppress weeds (any), prevent erosion, and add organic matter when chopped down. Wasatch County's seasonal pattern determines which species fit which gap.
Spring Cover Crops (3 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Buckwheat | May 21 | Jul 18 | — | Rapid growth, attracts pollinators, suppresses weeds |
| Sorghum-sudan grass | May 27 | Jul 25 | — | Massive biomass, breaks compaction, suppresses nematodes |
| White clover | Apr 21 | Aug 1 | ✓ Yes | Living mulch, fixes nitrogen, permanent ground cover |
Summer Cover Crops (1 options) — Fill gaps and suppress weeds between plantings
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Sunflowers | Jun 15 | Sep 5 | — | Deep roots break compaction, attract pollinators and beneficial insects |
Fall Cover Crops (6 options) — Plant after harvest to protect soil over winter
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Austrian winter peas | Jul 31 | May 5 | ✓ Yes | Fixes nitrogen, good for heavy clay soils |
| Daikon radish | Aug 18 | Apr 28 | — | Deep taproot breaks compaction, excellent for clay soils |
| Hairy vetch | Jul 14 | May 5 | ✓ Yes | Excellent nitrogen fixer, good for depleted soils |
| Oats | Aug 16 | May 5 | — | Quick biomass, winterkills in cold zones — no spring tillage needed |
| Winter rye | Jul 5 | May 5 | — | Suppresses weeds, prevents erosion, breaks up compacted soil |
| Winter wheat | Jul 6 | May 5 | — | Erosion control, weed suppression, good biomass |
Wind & Microclimate in Wasatch County
Why it matters: Pollinators avoid windy days. Wasatch County's 10.1 mph average wind isn't enough to stop bees and butterflies — but plant fruiting crops (tomatoes, peppers, squash) in protected microclimates and you'll see noticeably better fruit set.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 15 mph Summer: 10 mph
Fall: 13 mph Winter: 16 mph
Prevailing wind: W. Windy area — plant a windbreak hedge on the W side of your garden.
Windbreak Benefit
7.4/10
Strongly recommended — a windbreak (fence, hedge, or row of tall crops like corn or sunflowers) will significantly improve garden yields.
Frost Pocket Risk
High
Hilly terrain with 2,311 ft of elevation range — cold air pools in low spots. Avoid planting frost-sensitive crops in valleys.
Rainwater Harvesting in Wasatch County
How much water you can collect, when to collect it, and what size system you need for your garden.
The practical takeaway: Building a rainwater system is mostly about doing the math: roof area × annual rainfall × 0.6 = gallons you could realistically capture. For Wasatch County, that's your 17" times your roof.
Annual Collection
8,223 gal
Per 1,000 sq ft of roof area (at 80% collection efficiency)
Recommended Setup
8 rain barrels (55 gal each)
For a typical 500 sq ft garden. Serious collectors: consider a 2,000 gal tank.
Legal Status
Limited
Your state has quantity limits on rainwater collection — check local regulations before installing large systems.
Best Collection Months
Mar, Apr, May, Aug
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
Feb, Nov, Dec
Dry months when you'll rely on stored water — size your storage for this gap.
Rainwater collection tips for your area
- Your county receives approximately 16.5 inches of rain per year
- A 1,000 sq ft roof can collect roughly 8,223 gallons annually
- Check UT state regulations — rainwater harvesting has quantity limits
- In your dry climate, every drop counts — consider a larger cistern system
- Position collection tanks in shade to reduce evaporation and algae growth
