Start with Seed


Advantages of growing from seed

  • Cost-effective: Seeds are generally less expensive than seedlings, allowing you to plant more squash for less money.
  • Variety: You can choose from a wider range of squash varieties when starting from seed.
  • Healthier plants: Growing plants from seed allows you to nurture them in a controlled environment, reducing the risk of pests and diseases that can affect seedlings.

Best time to start squash seeds

  • Start seeds indoors about 4-6 weeks before your intended outdoor planting date.
  • Choose a date after the last expected frost in your area to avoid frost damage.

Cost savings

  • By growing from seed, you can save money on seedlings or store-bought vegetables.

Plant after Frost Danger


Importance of planting after frost danger has passed

  • Frost can kill young squash plants, reducing your chances of a successful harvest.
  • Waiting until the danger of frost has passed ensures the best growing conditions for your squash.

Varying planting times based on location

  • In cooler climates, wait until late spring or early summer to plant squash.
  • In warmer climates, plant squash in late winter, as long as the soil temperature is at least 60℉ (15℃).

Transplanting seedlings to garden

  • Harden off indoor seedlings before transplanting outdoors.
  • Space seedlings 12-24 inches apart, depending on the variety.

Provide Adequate Space and Sunlight


How much space squash plants need

  • Squash plants need room to grow and spread, so be sure to provide enough space between plants.
  • In general, allot about 4-6 feet between squash plants and 6-12 feet between rows.

The importance of direct sunlight

  • Squash plants need at least 6 hours of direct sunlight per day to grow and produce fruit.
  • Avoid planting squash in shaded areas to ensure they receive enough sunlight.

Suitable locations for growing squash

  • Plant squash in an area of your garden that receives full sun and has well-drained soil.
  • If space is limited, consider growing bush-type squash varieties, which require less space.

Growing squash in containers

  • Allow at least 18 inches of space between squash plants in containers.
  • Use large containers (5 gallons or larger) to ensure adequate root space and soil volume for proper growth.

Use Minimal Fertilizer


Why squash needs little fertilizer

  • Squash plants are typically heavy feeders but can grow well with minimal added nutrients.
  • Too much fertilizer can lead to excessive foliage growth and decreased fruit production.

The importance of well-drained soil

  • Squash plants prefer well-drained soil.
  • Well-drained soil helps prevent root rot and other issues caused by excess moisture.

Using compost instead of fertilizer

  • Add well-aged compost to your garden bed to provide squash plants with necessary nutrients.
  • Compost releases nutrients slowly over time, ensuring the plants have a steady supply of nourishment.

Maintain Consistent Moisture


How often to water squash plants

  • Water squash plants once or twice per week, depending on your climate and soil conditions.
  • Aim to provide about 1-2 inches of water per week.

The importance of constant moisture

  • Consistent moisture helps prevent fruit from cracking or developing uneven skin.
  • Regular watering helps decrease the risk of blossom-end rot, a common squash issue caused by inconsistent moisture levels.

Avoid overwatering

  • Too much water can lead to root rot, waterlogged soil, and other problems.
  • Water deeply and infrequently rather than frequent, shallow watering.

Harvesting Tips


Harvesting squash at the right time

  • Summer squash, such as zucchini and yellow squash, should be harvested when the fruit is still young and tender, about 6-8 inches long.
  • Winter squash, such as butternut and acorn squash, should be harvested when the fruit is mature and has a hard rind.

Edible squash flowers

  • Squash flowers can be eaten and are often used in recipes for a unique and delicious treat.

Handling prickly squash stems

  • Use gloves or a cloth to handle the prickly stems of some squash varieties to avoid discomfort.


By following these five tips, you can enjoy a bountiful harvest of squash in your garden this season. Start with seed, plant after frost danger, provide adequate space and sunlight, use minimal fertilizer, and maintain consistent moisture. Follow these guidelines, and you'll be enjoying an abundance of delicious squash in no time!
