Planting Conditions

Mississippi has a humid subtropical climate with long, hot summers and mild winters. The state falls within USDA Hardiness Zones 7b to 9a, providing an extended growing season. The southern coastal regions typically experience warmer temperatures earlier in the spring, allowing for an earlier start to planting compared to the northern parts of the state.

Start pumpkin seeds indoors from mid-March to mid-April to give your plants a strong start. Once the danger of frost has passed and soil temperatures have warmed to at least 70°F, transplant the seedlings outdoors. Direct sowing is also an option from mid-April to early June.

Greenhouse Growing

In Mississippi, where the growing season can be extended by managing the heat and humidity, a greenhouse is a valuable tool. It allows you to control the environment, giving your pumpkin plants the best conditions for growth even when outdoor conditions are less favorable.

If you grow pumpkins in a greenhouse or polytunnel, though, you should be aware that pumpkins take up a lot of space. You can reduce the amount of space required by training vining pumpkins up a vertical frame or trellis.

Currently, the 8x10x7.5 FT Greenhouse is priced at $999. It’s a great investment for ensuring your pumpkins thrive all year round.

Timing the Harvest for Halloween

In Mississippi, planting pumpkins between mid-April and early June will ensure they are ready for Halloween. Pumpkins typically take 90 to 120 days to mature, depending on the variety. Planting by early June ensures they’ll be ready by late October.

Harvesting Tips

  • Monitor Growth: Regularly check your pumpkins as they grow to ensure they are maturing properly.
  • Cut the Pumpkin: Use a sharp knife or pruning shears to cut the pumpkin from the vine, leaving a few inches of stem attached. This helps with storage.
  • Cure the Pumpkins: Cure pumpkins in a warm, dry spot for about a week to toughen the skin and improve storage life.

Pumpkin Plant Care Tips

Watering:

  • Water your pumpkins consistently, especially during dry spells. Ensure the soil remains moist but not waterlogged to avoid root problems.

Fertilizing:

  • Apply a balanced fertilizer at planting time and again when the vines start to spread. Adding compost to the soil before planting helps improve soil quality and moisture retention.

Pest and Disease Management:

  • Watch out for pests like squash bugs, cucumber beetles, and aphids, which are common in Mississippi’s climate. Organic methods or integrated pest management can help protect your plants.
  • Monitor for powdery mildew and other fungal diseases, especially during humid periods. Ensure good air circulation and avoid overhead watering to reduce disease risks.

Harvesting Pumpkins:

  • Harvest pumpkins when they have developed a deep color and the skin is firm. This ensures they are mature and ready for storage.

Smart Tip: Don’t throw away the seeds from the pumpkin after Halloween. Instead, save them and have free pumpkins year after year.
