Meagher County, MT — Planting Guide
This month in Meagher County, Montana
Your Meagher County, Montana garden is entering a new phase. Here's what's on the schedule for July and why each task matters now.
-
Move basil, cucumber, and peppers into the garden
Your last frost (June 10) has passed. These warm-season crops can handle outdoor soil now.
-
Indoor seed-starting week for cucumber, kale, and lettuce
Give them 6–8 weeks indoors before the last frost and you'll transplant into warm soil with seedlings that are already leaping.
-
It's harvest week for lettuce, radish, and arugula
Check every 1–2 days. Many of these get tough or go to seed if you wait too long.
-
Direct-sow alliums, crocus, and daffodils for cool weather
Mid-season soil is hot. Sow a bit deeper than the packet suggests to find cooler, damper ground.
August prep starts now
- Starting indoors: basil, peppers, and pole beans
- First harvests: basil, carrots, and cucumber

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 | Sep 23 | 91 days |
| Cautious | Jun 17 | Sep 16 | 91 days |
| Average year | Jun 10 | Sep 8 | 90 days |
| Optimistic | May 28 | Sep 3 | 98 days |
| Aggressive (risky) | May 13 | Aug 24 | 103 days |
Not very — frost dates can vary by ±42 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 2.1 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.

What to Plant After Your Harvest
After your first crops finish, use the remaining frost-free days to grow a second round.
Sunlight & Day Length in Meagher County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
Why this matters: The longest day at Meagher County's latitude gets longer the further north you go. Strawberries, garlic, onions all care. The shortest day gets shorter — which limits winter growing for greens without artificial light.

Peak Sun Hours
11.3 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.

Wind & Microclimate in Meagher County
Why it matters: Light wind is good (strengthens stems, aids pollination); strong wind is bad (snaps stems, dries leaves, scatters seeds). Meagher County averages 11.1 mph. If you garden near coast, ridge, or open plains, you're likely above that — plan for it.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 15 mph Summer: 11 mph
Fall: 12 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 2,059 ft of elevation range — cold air pools in low spots. Avoid planting frost-sensitive crops in valleys.
Rainwater Harvesting in Meagher County
How much water you can collect, when to collect it, and what size system you need for your garden.

Annual Collection
7,127 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
Mar, Apr, May, Aug
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
Feb, Jun, 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 14.3 inches of rain per year
- A 1,000 sq ft roof can collect roughly 7,127 gallons annually
- Rainwater harvesting is fully legal in your state
