What to do in August
August rewards gardeners who work with the weather, not against it. Here's how to stay in step this month in Lincoln County, Colorado.
-
Pick basil, carrots, and cucumber
If you can't use it all right away, check the food-preservation section of your planner.
-
Kick off the fall garden with alliums, crocus, and daffodils
Mid-season soil is hot. Sow a bit deeper than the packet suggests to find cooler, damper ground.
September prep starts now
- First harvests: basil, cucumber, and green beans

Monthly Watering Calendar for Lincoln County
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
For new gardeners: Most vegetables want about 1 inch of water per week. Lincoln County gets 14" a year — months that hit that 1"/week need zero supplemental watering; months that fall short, the table tells you how much to add. Saves you from drowning roots and from drought-stressing plants into bolting.

Frost Risk Probability
Based on 29 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) | May 30 | Oct 12 | 135 days |
| Cautious | May 17 | Oct 7 | 143 days |
| Average year | May 13 | Oct 3 | 143 days |
| Optimistic | May 9 | Sep 23 | 137 days |
| Aggressive (risky) | Apr 30 | Sep 12 | 135 days |
Not very — frost dates can vary by ±30 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 2.2 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.

Finding local nurseries & garden centers in Lincoln County
Why Buy Local
Local nurseries carry plants that are proven to grow in your area. Staff can give you advice specific to Lincoln County's soil and climate that big-box stores can't. Plants from local growers are typically hardier because they're already acclimated to your zone.
How to Find Them
Search for "nurseries near Lincoln County CO" or "garden center Lincoln County" on Google Maps. Also check with your extension office — they often maintain lists of reputable local nurseries and plant sales.
Community gardens & gardening groups
Community gardens are a great way to learn from experienced gardeners in your area, especially if you're limited on space.

Sunlight & Day Length in Lincoln County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
The practical takeaway: Plants use day length as their seasonal clock. Some crops flower when days lengthen (most flowers), some when days shorten (chrysanthemums, soybeans). Lincoln County's curve is the timing layer beneath everything you grow.
Longest Day
14.7 hours
Summer solstice daylight
Shortest Day

Winter solstice daylight
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 Lincoln County
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
Quick context: Air temperature lies. Your air can be 70°F in April but the soil 4 inches down is still 50°F — too cold for tomatoes or peppers to root properly. Lincoln County's soil temperature curve tells you the real planting window. A $5 soil thermometer pays for itself in one season.

Cover Crops for Lincoln County
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
Quick context: You don't need a farm to use cover crops. A 4x8 raised bed accepts cover crops just as well as a half-acre. Lincoln County's climate determines the calendar; the principle is universal.
Spring Cover Crops (3 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Buckwheat | May 22 | Aug 1 | — | Rapid growth, attracts pollinators, suppresses weeds |

Wind & Microclimate in Lincoln County
Quick context: Light wind is good (strengthens stems, aids pollination); strong wind is bad (snaps stems, dries leaves, scatters seeds). Lincoln County averages 11.7 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: 16 mph Summer: 12 mph
Fall: 11 mph Winter: 16 mph
Prevailing wind: W. Windy area — plant a windbreak hedge on the W side of your garden.
Windbreak Benefit
7.1/10
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 2,542 ft of elevation range — cold air pools in low spots. Avoid planting frost-sensitive crops in valleys.
Rainwater Harvesting in Lincoln County
How much water you can collect, when to collect it, and what size system you need for your garden.
What this means for you: A single rain barrel under a downspout catches 50 gallons in a 0.5" storm. Lincoln County's 14" annual rainfall means even modest harvesting systems quickly amortize their cost in water savings.
Annual Collection
6,877 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
Apr, May, Jul, 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 13.8 inches of rain per year
- A 1,000 sq ft roof can collect roughly 6,877 gallons annually
- Check CO 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
