Planting Green Hubbard Squash: Tips for Success

  1. Choose the Right Location: Green hubbard squash plants require full sunlight (at least 6-8 hours a day) and well-draining soil. Amend the soil with organic matter such as compost or aged manure to improve fertility and drainage. Avoid planting in low-lying areas where water might accumulate.
  2. Start Seeds Indoors: To get a head start on the growing season, sow green hubbard squash seeds indoors approximately 3-4 weeks before the last expected frost date. Use biodegradable pots to avoid transplant shock, and keep the seedlings in a warm, well-lit area.
  3. Transplant Seedlings: When the seedlings have developed 2-3 true leaves and nighttime temperatures are consistently above 50°F (10°C), it’s time to transplant them outdoors. Harden off the seedlings by gradually exposing them to outdoor conditions for a week. Space the plants 3-4 feet apart in rows 6-8 feet apart, ensuring they have ample room to grow.
  4. Direct Sowing: If you prefer to sow seeds directly outdoors, wait until the soil has warmed to at least 60°F (15°C) and all danger of frost has passed. Plant seeds 1 inch deep and 3-4 feet apart, thinning to the most vigorous seedlings once they have developed 2-3 true leaves.

Growing Green Hubbard Squash: Expert Care Tips

  1. Watering: Green hubbard squash plants require consistent moisture, especially during fruit development. Water deeply once a week, providing 1-1.5 inches of water per week. Use a soaker hose or drip irrigation system to minimize wetting the leaves, which can lead to disease.
  2. Fertilizing: Apply a balanced fertilizer, such as a 10-10-10 formula, at planting and again when the plants begin to flower. Follow the package instructions for application rates, and avoid over-fertilizing, as it can lead to excessive vine growth and reduced fruit production.
  3. Weeding: Keep the area around your green Hubbard squash plants weed-free to reduce competition for nutrients and water. Mulching with organic material like straw or wood chips can help suppress weeds and retain soil moisture.
  4. Pest and Disease Control: Monitor your plants for common pests such as squash bugs, cucumber beetles, and vine borers. Use insecticidal soap, neem oil, or other organic pest control methods to manage infestations. Practice crop rotation and good sanitation to minimize disease issues.

Harvesting Green Hubbard Squash: When and How

Timing: Green hubbard squash is typically ready to harvest 100-120 days after planting, depending on the specific variety. The rind should be hard and dull, and the stem should be dry and brown. A light frost can help to sweeten the flavour, but be sure to harvest before a hard freeze.

Method: Use a sharp, clean pair of pruners or a knife to cut the squash from the vine, leaving 2-3 inches of stem attached. This will help prevent rot and extend storage life.

Storing Green Hubbard Squash: Tips for Longevity

  1. Curing: After harvesting, cure the green hubbard squash by allowing them to sit in a warm, dry, and well-ventilated area for 7-10 days. This process helps to harden the rind and heal any cuts, extending the storage life of the squash.
  2. Ideal Storage Conditions: Store green hubbard squash in a cool, dark, and well-ventilated area, such as a basement or cellar, where the temperature is consistently between 50-55°F (10-13°C) and the relative humidity is around 60-70%. Proper air circulation is crucial to prevent mold and rot.
  3. Proper Storage Techniques: Place the squash on a shelf or rack, ensuring they do not touch each other. This helps to promote airflow and prevents the spread of potential rot. Regularly inspect the stored squash for any signs of decay and remove affected fruits immediately to prevent further contamination.
  4. Storage Life: When properly stored, green hubbard squash can last for 3-6 months, depending on the specific variety and storage conditions. Check on the squash periodically and use them in your favourite recipes as needed.
