In zone 9, plant pumpkins outside from about March 17, two weeks after your last spring frost, once the soil has thoroughly warmed. Most varieties need about 100–120 days. For Halloween pumpkins, wait until late June or early July: pumpkins planted in spring ripen in summer and may rot before October.

Pumpkin timing in zone 9
| Task | When |
|---|---|
| Start indoors (optional) | February 17 – February 24 |
| Plant outside | March 17 |

| Harvest | When the rind is hard and the color deep |
Most of zone 9 sees its last spring frost between February 16 and March 15 (typical March 3) and its first fall frost between November 15 and December 5 (typical November 25). Pumpkin seed won’t sprout in cold soil, and frost kills the vines. The tool above uses the weather station closest to your ZIP code.
Why pumpkins wait for warm soil
Pumpkins are tender, warm-season plants. The seed won’t sprout in cold soil, and frost kills the vines. They go out about two weeks after the last spring frost, once the soil has thoroughly warmed, and need 100–120 days to ripen. If you want pumpkins for Halloween, timing the planting matters as much as the frost date.
Best pumpkin varieties for zone 9
Zone 9 has a long season, so timing matters more than variety. Good choices include:
- Carving pumpkins such as Howden’s Field and Big Max.
- Pie pumpkins such as Small Sugar.
- Cushaws, such as Green-Striped Cushaw, are traditional in the South and good for pies.
- Miniature pumpkins such as Jack-Be-Little.
How to plant pumpkins
- Sow seeds 1 inch deep, 4–5 seeds per hill, once the soil is warm.
- Space hills 5–6 feet apart in rows 10–15 feet apart for vining types, closer for bush types.
- Thin to the best 2–3 plants per hill.
- Water deeply, keeping the leaves dry.
- Let the bees work. Avoid insecticides while flowers are open.
Zone 9 pumpkin tips
- Plant later for fall. Spring plantings ripen in summer heat and don’t keep until Halloween.
- Expect pests. Cucumber beetles, squash bugs and powdery mildew build up through summer, so check plants often.
- Protect pollinators. Spray only in the evening, after flowers close.
- Store pumpkins dry and cool, around 45–55 °F, never damp.
Harvesting and storing pumpkins
Harvest when the pumpkin has a deep, solid color and a hard rind. Cut the stem with shears, leaving 3–4 inches attached, and wear gloves because the stems are prickly. Bring pumpkins in before a heavy frost. Store sound, unblemished pumpkins in a dry place at about 45–55 °F, where they keep for months. Don’t refrigerate them or store them somewhere damp.

Frequently asked questions
Is it too late to plant pumpkins in zone 9 in April?
Not at all. In the South, early summer is the right time to plant pumpkins for a fall harvest.
When should I plant pumpkins for Halloween in zone 9?
In late June or early July. Pumpkins planted in spring ripen too early in warm climates.
How long do pumpkins take to grow?
Most need 100–120 days from planting to harvest. Miniatures are quicker; giants take longest.
Why are my pumpkin flowers falling off?
The first flowers are male and drop off after a day. Female flowers, with a small pumpkin at the base, come later.
How much space do pumpkins need?
Vining pumpkins need 50–100 square feet per hill, and giants about 150. Bush and miniature types need much less.
