When To Plant Pumpkins In Ms

If you’re planning to grow pumpkins in Mississippi, timing is everything. Knowing exactly when to plant pumpkins in MS is the first step to a successful harvest of big, orange jack-o’-lanterns or tasty pies. Our climate offers a long, warm growing season, but planting at the right moment protects your vines from late frosts and ensures they mature before the first fall chill.

For most of Mississippi, the best planting window is from late April through mid-June. This schedule uses our full summer heat to grow vigorous vines, with fruit developing in time for autumn. Planting too early risks a late frost damaging young seedlings, while planting to late might mean your pumpkins won’t ripen before frost returns.

Understanding Mississippi’s Growing Zones

Mississippi spans USDA plant hardiness zones 7b through 9a. This means our last spring frost dates and first fall frost dates vary.

North MS (Zone 7b): Last frost around April 7-15. Aim to plant seeds outdoors from May 1 to June 15.
Central MS (Zone 8a/b): Last frost around March 25-April 5. Planting from late April to June 10 is ideal.
South MS (Zone 9a): Last frost as early as March 15. You can start planting in mid-April and continue into late June.

A good rule is to wait until soil temperatures are consistently above 70°F. Pumpkins seeds will just rot in cold, damp ground.

Planning by Pumpkin Type and Use

Your choice of pumpkin variety affects your planting date. All pumpkins need 75 to 120 frost-free days to mature, depending on type.

Giant Pumpkins (e.g., ‘Atlantic Giant’): Need 120+ days. Plant in late April or early May in North MS, and by mid-May in South MS.
Jack-O’-Lanterns (e.g., ‘Howden’, ‘Magic Lantern’): Need 100-110 days. Plant from early May to early June.
Pie Pumpkins (e.g., ‘Sugar Pie’, ‘Cinderella’): Need 95-110 days. Plant from mid-May to mid-June.
Miniature Pumpkins (e.g., ‘Jack Be Little’): Need 90-100 days. You can sucesfully plant these in early to late June.

Count backwards from your desired harvest date (like October 15th for Halloween) using the “days to maturity” on your seed packet to find your best planting date.

Step-by-Step Planting Guide for Mississippi Gardeners

Follow these steps to get your pumpkin patch off to a strong start.

1. Site Selection and Soil Prep

Pumpkins are heavy feeders and need space. Choose a spot with full sun (at least 6-8 hours daily). The soil should be well-draining and rich in organic matter.

In early spring, work in 3-4 inches of compost or well-rotted manure into the soil.
Test your soil pH; pumpkins prefer a range of 6.0 to 6.8.
Create raised hills or rows to improve drainage, which is crucial in our sometimes rainy springs.

2. Planting Seeds Directly vs. Starting Indoors

Pumpkins generally prefer direct sowing, as their roots are sensitive to disturbance.

Direct Sowing: Plant seeds 1 inch deep. Sow 4-5 seeds per hill, with hills spaced 4-6 feet apart for vines, or 2-3 feet for bush varieties. Thin to the 2-3 strongest seedlings per hill once they have true leaves.
Starting Indoors (for a slight head start): If you want to start indoors, use biodegradable pots 3-4 weeks before your outdoor planting date. Do not start them to early, or they’ll become root-bound. Transplant carefully to avoid damaging roots.

3. Watering and Mulching

Consistent watering is key, especially during fruit set and development.

Provide 1-2 inches of water per week, aiming at the base of the plant to keep leaves dry and prevent disease.
After seedlings are established, apply a thick layer of straw or pine straw mulch. This conserves moisture, suppresses weeds, and keeps the developing fruit clean and off the damp soil.

Seasonal Care Through Mississippi Summer

Our hot, humid summer presents specific challenges for pumpkin vines.

Fertilizing for Growth

Use a balanced fertilizer at planting. Once vines start to “run” (about 2-3 feet long), switch to a low-nitrogen, high-phosphorus fertilizer to encourage blooming and fruiting instead of just leafy growth. Over-fertilizing with nitrogen is a common mistake.

Pest and Disease Management

Stay vigilant for common Mississippi garden pests and diseases.

Squash Bugs & Vine Borers: Check leaf undersides daily. Use row covers early in the season, removing them when flowers appear for pollination. Hand-pick bugs and eggs.
Powdery Mildew: This white fungus thrives in humidity. Ensure good air circulation, water at the soil level, and consider a fungicide labeled for edible crops if it appears.
Blossom End Rot: Caused by calcium deficiency and irregular watering. Maintain consistent soil moisture to help prevent it.

Pollination Tips

If you see flowers but no fruit, you might have a pollination issue. Pumpkins have separate male and female flowers. Bees are the primary pollinators.

To attract bees, avoid using broad-spectrum insecticides during bloom.
If bee activity is low, you can hand-pollinate. Use a small brush to transfer pollen from a male flower (straight stem) to the center of a female flower (small fruit at base).

Harvesting and Storing Your Mississippi Pumpkins

Your pumpkins are ready for harvest when they have reached their full, deep color and the rind is hard.

The stem should be dry and beginning to cork. Use pruning shears to cut the stem, leaving 3-4 inches attached.
Never carry a pumpkin by its stem; if it breaks, it creates an entry point for rot.
For storage, cure pumpkins (except miniatures) in a warm, dry place for 10-14 days. This hardens the skin. After curing, store in a cool (50-55°F), dry place where they can last for months.

Frequently Asked Questions (FAQ)

What is the latest you can plant pumpkins in Mississippi?

For North Mississippi, aim to plant by June 20th. In Central and South Mississippi, you can plant quick-maturing pie or small varieties as late as early July and still expect a harvest before the first frost.

Can you plant pumpkins in July in MS?

Planting in July is generally to late for most standard varieties, as they won’t mature in time. However, you could try very fast-maturing mini varieties (around 85 days) if planted by the first week of July in South MS, with the understanding that pest pressure will be high.

How long does it take to grow pumpkins?

It takes 75 to 120 days from planting the seed to harvest, depending on the variety you choose. Always check the “days to maturity” on your seed packet and count back from your target harvest date.

Do pumpkins grow well in Mississippi?

Yes, they grow exceptionally well if planted at the right time. Our long, hot summers provide the heat and growing season pumpkins love. The main challenges are our high humidity, which can promote fungal diseases, and intense pest pressure, which requires regular monitoring.

Getting your planting timing right is the most important factor for a great pumpkin harvest in our state. By following these guidelines tailored to Mississippi’s climate, you’ll give your pumpkin plants the best possible start. With proper site selection, consistent care, and a watchful eye for pests, you’ll be rewarded with a plentiful patch come fall.
