  1. Set out basil, cucumber, and peppers seedlings

    Plant tomatoes deep — bury the stem up to the first true leaves to grow extra roots. Everything else goes in at the same depth it grew in the tray.

  2. Get cucumber, kale, and lettuce seeds going inside

    Label every cell. You will absolutely forget which is which otherwise.

  3. It's harvest week for lettuce, radish, and arugula

    Don't tug. Use scissors or pruners for clean cuts — torn stems invite disease.

A few tasks this May that'll pay off in June
  • 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

Too early frost risk Safe to Plant Apr 20 → Oct 23 186 frost-free days Protect crops frost returns Apr May Jun Jul Aug Sep Oct Nov Dec Safe: May 11 Protect by: Nov 3

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 11 Nov 3 176 days
Cautious Apr 27 Oct 28 184 days

Organic pest management tips
  • Use row covers on susceptible crops during peak pest months
  • Apply neem oil preventatively every 7-14 days during active pest season
  • Interplant with strong-scented herbs (basil, marigold) to confuse pests
  • Hand-pick larger pests (beetles, caterpillars) in early morning when they're sluggish
  • Practice crop rotation — never plant the same family in the same spot within 3 years

Wind & Microclimate

Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.

Seasonal Wind Speed

Spring: 11 mph   Summer: 9 mph

Fall: 9 mph   Winter: 12 mph

Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.

Windbreak Benefit

5/10

Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.

Frost Pocket Risk

Moderate

Some terrain variation (513 ft range). Garden on slopes or higher ground if possible to avoid late-season frost pockets.

Rainwater Harvesting Potential

How much water you can collect, when to collect it, and what size system you need for your garden.

Annual Collection

23,973 gal

Per 1,000 sq ft of roof area (at 80% collection efficiency)

6 rain barrels (55 gal each)

For a typical 500 sq ft garden. Serious collectors: consider a 500 gal tank.

Legal Status

Unrestricted

Rainwater harvesting is fully legal in your state with no restrictions.

Best Collection Months

Mar, Jul, Sep, Dec

Highest rainfall months — your barrels will fill up quickly during these months.

Months to Draw From Storage

Feb, Oct, Nov

Dry months when you'll rely on stored water — size your storage for this gap.
