How to Grow Gem Squash from Seeds: The Basics

When you grow gem squash from seeds, you’re working with a warm-season crop that loves sunshine and well-drained soil.
 
Gem squash seeds are easy to handle and germinate quickly when conditions are right.
 
Here’s what you need to know about growing gem squash from seeds successfully.
 

1. Start with Fresh, Quality Gem Squash Seeds

The first step in how to grow gem squash from seeds is getting good seeds.
 
Gem squash seeds are usually small, flat, and pale, and you can find them at garden centers or online.
 
Fresh seeds from a reputable supplier give you the best germination rate when you grow gem squash from seeds.
 
If you saved seeds from a previous gem squash harvest, make sure they were fully mature and dried properly before storage.
 

2. Choose the Right Time to Sow Gem Squash Seeds

Timing matters when you grow gem squash from seeds.
 
Gem squash seeds need warm soil, so wait until all danger of frost has passed outside.
 
If you want a head start, sow gem squash seeds indoors about three to four weeks before your last frost date.
 
That way, your gem squash seedlings will be ready to go into the ground as soon as the weather warms up.
 

3. Use the Right Soil and Containers

To grow gem squash from seeds indoors, use small pots or seed trays filled with a lightweight seed-starting mix.
 
Plant each gem squash seed about one inch deep and cover it gently with soil.
 
Keep the soil moist but not soggy, and place the trays in a warm spot—around 70 to 85°F is ideal for gem squash seeds to sprout.
 
Most gem squash seeds germinate within seven to fourteen days.
 

Transplanting and Caring for Gem Squash Seedlings

Once your gem squash seeds have sprouted, the real fun begins.
 
Here’s how to keep your gem squash growing strong after germination.
 

1. Harden Off Your Gem Squash Seedlings

Before you move your gem squash seedlings outside, harden them off over a week or so.
 
Start by placing them outdoors in a sheltered spot for a few hours each day, gradually increasing their time outside.
 
This helps your gem squash plants adjust to direct sun, wind, and temperature changes without going into shock.
 

2. Plant Gem Squash in Full Sun

Gem squash plants love full sun, so pick a spot that gets at least six to eight hours of direct light daily.
 
Space your gem squash plants about three feet apart, because they sprawl and need room to grow.
 
Amend the soil with compost or aged manure to give your gem squash plenty of nutrients.
 

3. Water and Feed Your Gem Squash Regularly

Consistent watering is key when you grow gem squash from seeds.
 
Water deeply once or twice a week, aiming for about an inch of water per week, and let the soil dry slightly between waterings.
 
Feed your gem squash with a balanced fertilizer every few weeks, but don’t overdo the nitrogen or you’ll get leaves instead of fruit.
 

4. Watch for Pests and Pollination

Gem squash plants can attract pests like aphids, squash bugs, and vine borers.
 
Check your plants regularly and remove pests by hand or use insecticidal soap when needed.
 
Also, gem squash rely on bees for pollination, so plant flowers nearby to attract pollinators, or hand-pollinate if bee activity is low.
 

Harvesting Gem Squash Grown from Seeds

Your gem squash will be ready to harvest about 80 to 100 days after planting, depending on the variety and growing conditions.
 
Gem squash are usually picked when they’re small, tender, and bright green—about the size of a tennis ball or slightly larger.
 
If you wait too long, the skin hardens and the flavor turns starchy, so check your gem squash often once they start forming.
 
Cut them from the vine with a sharp knife, leaving a short stem attached, and store them in a cool, dry place.
