Coconino County, AZ — Planting Guide
Your June game plan for Coconino County, Arizona
Each item below is timed to Coconino County, Arizona's frost dates and soil temperatures. Skip nothing, stress about nothing.
-
Set out basil, cucumber, and peppers seedlings
Bring a watering can to the bed. Each transplant gets a drink the moment it's in the ground, not ten minutes later.
-
Seed basil, cucumber, and green beans outdoors
Keep the top inch of soil moist until germination — a gentle morning watering for 5–7 days does the job.
-
Get cucumber, zucchini, and acorn squash seeds going inside
Bottom-water once the first true leaves appear — it keeps stems dry and knocks back damping-off.
-
Pick radish, cress, and dianthus
This is the payoff month. Bring a basket, bring a friend, and get into the beds.
To set up a strong July, finish these tasks
- Starting indoors: basil, kale, and lettuce
- First harvests: carrots, green beans, and kale
- Fall sowing: carrots, kale, and lettuce

Monthly Watering Calendar for Coconino County
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
The practical takeaway: Watering math is simple: 1 inch of rainfall delivers ~600 gallons to a 1,000 sq ft garden. Coconino County's 14" annual rainfall covers some months entirely; others need a few hours of drip irrigation per week. The calendar tells you which is which.

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 24 | Nov 5 | 134 days |
| Cautious | Jun 14 | Oct 20 | 128 days |
| Average year | May 28 | Sep 27 | 122 days |
| Optimistic | Apr 17 | Sep 15 | 151 days |
| Aggressive (risky) | Apr 1 | Sep 2 | 154 days |
Not very — frost dates can vary by ±83 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.
Yes — growing seasons are getting longer here (about 4.9 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.

Sunlight & Day Length in Coconino County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
What this means for you: Photoperiod-sensitive crops will fail spectacularly if planted at the wrong latitude. Sweet onions in Michigan? Tiny. Spanish onions in Florida? Tiny. Match variety to Coconino County's daylight pattern and you'll see the difference.

Cover Crops for Coconino County
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
Quick context: A fall-planted cover crop in Coconino County is the closest thing to free soil amendment. Plant cereal rye or hairy vetch after harvest; chop it down before it flowers in spring; the soil it leaves behind out-grows any store-bought compost.
Spring Cover Crops (3 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Buckwheat | Jun 1 | Jul 26 | — | Rapid growth, attracts pollinators, suppresses weeds |

Wind & Microclimate in Coconino County
Why this matters: Why care about wind? Above about 10 mph, evaporation jumps and pollinators struggle to land on flowers. Coconino County's 10.2 mph average means you can plant tall crops without much support, but it doesn't mean ignore wind — a 20+ mph storm still snaps unstaked tomatoes.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 14 mph Summer: 10 mph
Fall: 9 mph Winter: 12 mph
Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
7.2/10
Strongly recommended — a windbreak (fence, hedge, or row of tall crops like corn or sunflowers) will significantly improve garden yields.
Frost Pocket Risk
Moderate
Some terrain variation (655 ft range). Garden on slopes or higher ground if possible to avoid late-season frost pockets.
Rainwater Harvesting in Coconino County
How much water you can collect, when to collect it, and what size system you need for your garden.
Why it matters: The first inch of rain washes the roof clean — a first-flush diverter sends it to waste before the barrel fills. Worth the extra $20 for cleaner garden water. Coconino County gets 14" annually, so you'll fill and flush many times per year.
Annual Collection
6,927 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
Unrestricted
Rainwater harvesting is fully legal in your state with no restrictions.
Best Collection Months
Jul, Aug, Sep, Oct
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
Feb, Mar, Apr, May, Jun, 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 13.9 inches of rain per year
- A 1,000 sq ft roof can collect roughly 6,927 gallons annually
- Rainwater harvesting is fully legal in your state
- In your dry climate, every drop counts — consider a larger cistern system
- Position collection tanks in shade to reduce evaporation and algae growth
Soil & Growing Conditions in Coconino County
Soil Type
Sandy Loam
Soil pH 7.2–8.6 · Excessively Drained drainage

Drought stress: 9.5/10
Very high drought stress. Irrigation is critical for garden success. Focus on water-efficient techniques and drought-adapted crops.
Season Tips
122-day frost-free season
A short season means indoor starts are critical for warm-season crops. Prioritise cold-hardy, fast-maturing varieties and use row covers to extend autumn harvests.
