In zone 7, plant cantaloupe (muskmelon) and other melons outside around May 1, two weeks after your last spring frost, once the soil is warm. For transplants, start seeds indoors from April 3 to April 10. Expect ripe melons from about July 10.

Melon timing in zone 7
| Task | When |
|---|---|
| Start indoors | April 3 – April 10 |
| Transplant outside | May 1 |
| First harvest | July 10 – July 20 |
| Lay black plastic (optional) | Before planting, for earlier melons |
| Cut back water | Once the fruit starts to ripen |
| Harvest cantaloupe | At full slip, when the stem separates easily |
Most of zone 7 sees its last spring frost between April 10 and April 26 (typical April 17) and its first fall frost between October 18 and October 29 (typical October 23). Melons need warm soil and warm weather, and frost kills them. The tool above uses the weather station closest to your ZIP code.
Why melons wait for warm weather
Melons are warm-season crops. Frost kills them, and cool soil and weather stall their growth. They go out about two weeks after the last spring frost, once the soil is warm. Starting transplants indoors gives you a head start of up to four weeks.
Best melon varieties for zone 7
Zone 7 summers suit most melons:
- Cantaloupe (muskmelon), with netted skin and orange flesh, the most popular home-garden melon.
- Honeydew and specialty melons, which usually need a longer, warmer season.
- True cantaloupes such as Charentais, smooth-skinned and French, but less common in American gardens.
How to plant melons
- Start seeds indoors about three to four weeks before transplanting, in individual pots.
- Lay black plastic or landscape fabric for larger, earlier harvests.
- Space plants about 2 feet apart in rows 5–6 feet apart, or 2–3 plants per hill.
- Water well during establishment and fruit growth.
- Cut back watering once the fruit begins to ripen.
Zone 7 melon tips
- Wait for warm soil, about two weeks after your last frost.
- Space plants about 2 feet apart in rows 5–6 feet apart.
- Help the bees. Poor fruit set is common in rainy weather; avoid pesticides during bloom.
- Cut back water as fruit ripens for better flavor.
Harvesting melons
Pick cantaloupe at full slip, when the melon separates from the stem with a gentle push. Most melons ripen 80–100 days after transplanting, and each plant gives about 2–4 fruits.

Frequently asked questions
Is it too late to plant melons in zone 7 in May?
It may still work. Count the days to maturity on the seed packet back from your first frost, around October 23.
How do I know a cantaloupe is ripe?
Wait for full slip: a ripe cantaloupe separates from the stem with a gentle push.
Can I plant melons before the last frost?
No. Melons are killed by frost and need warm soil. Plant about two weeks after your last frost.
What is the difference between cantaloupe and muskmelon?
In the US, the netted, orange-fleshed melons sold as cantaloupe are muskmelons. True cantaloupes, such as Charentais, are smooth-skinned European melons.
Why are my melons not sweet?
Overwatering as they ripen dilutes the flavor. Cut back water once the fruit starts to ripen, and harvest at full slip.
