When to Plant Watermelon in Esmeralda County, NV
What to do in May
Here's what deserves your attention in Esmeralda County, Nevada this month. Everything below is tailored to Zone 7a and timed around your local frost dates.
-
Get watermelon in the ground
Harden off for 7 days — a little more sun each day — before planting. That's the difference between a seedling that thrives and one that stalls.
-
Plant watermelon from seed, right in the garden
Thin ruthlessly once seedlings are up. Crowded roots mean smaller crops from every plant.
-
Start watermelon indoors
You're about 23 weeks out from your last frost — the perfect window to get these germinating indoors.

Watermelon Heat Requirements (GDD)
What are Growing Degree Days (GDD)?
Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.
Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.
