Gem squash seeds should be sown in spring to early summer in temperate areas
Gem squash is a unique round, dark green summer squash known for its delicious flavour and beautiful green skin. It is a South African favourite and can be cooked in a variety of ways. In temperate areas, gem squash seeds should be sown in spring to early summer.
When planting your gem squash seeds, choose a spot with full sun and well-drained soil. This variety of squash requires plenty of sunlight and warm soil to germinate and grow. Ensure the soil temperature has reached around 21°C (70°F) before planting the seeds. You can plant the seeds directly into the garden bed or start them indoors about two to three weeks before the last frost date in your area.
Sow the seeds in rows, 2 cm deep and 1 m apart. Keep the soil moist but not waterlogged, as this will cause the seeds to rot. Water the plants deeply once a week, being careful not to wet the leaves as this can lead to fungal diseases. You can also mulch around the plants to help retain moisture in the soil and prevent weed growth.
Gem squash is relatively easy to look after once it's growing. Regular watering and feeding are all you need for this vegetable to thrive. It is important to note that squash is prone to powdery mildew in subtropical and tropical areas, so it is unlikely to do well in these climates.

Germination occurs at 21-35°C and seeds will rot in cold, wet soil
Gem squash is a unique round, dark green summer squash known for its delicious flavour and beautiful green skin. It is easily grown in a sunny location and is related to the butternut squash. It is edible at all stages of its growth.
When planting your gem squash, it is important to note that germination occurs at 21-35°C. This is the ideal soil temperature for germination. It is best to wait until the soil temperature has reached at least 21°C before planting the seeds. The seeds should be planted about 2.5 cm deep and spaced about 45 cm apart. It is also important to note that gem squash seeds will rot in cold, wet soil. Therefore, it is crucial to keep the soil moist but not waterlogged. Water the plants deeply about once a week, being careful not to wet the leaves as this can lead to fungal diseases.
To ensure the success of your gem squash seeds, it is recommended to sow them directly into the garden bed in the sunniest spot, especially in colder climates. Prepare the soil by adding compost to it before sowing for the best results. The soil should be rich and well-drained. Additionally, the seeds should be sown in rows about 1 metre apart.
Once the seeds have germinated, provide them with proper care and maintenance. Continue to keep the soil moist and consider mulching around the plants to help retain moisture and prevent weed growth. Protect your seeds from rodents and birds, which may eat them. You can do this by covering them with an upturned pot.

Sow seeds 2-2.5cm deep and 45-60cm apart
When sowing gem squash seeds, it's important to space them out adequately to ensure healthy growth. The ideal depth for planting gem squash seeds is between 2 and 2.5 cm, with the seeds placed about 45 to 60 cm apart. This spacing allows each seedling enough room to develop a strong root system and grow into a healthy plant.
It is recommended to sow gem squash seeds directly into the garden bed in a sunny spot, particularly in colder climates. The soil should be rich and well-drained, with a temperature of around 21°C (70°F) to provide the best environment for germination and growth. Before sowing, it is beneficial to add compost to the soil to enhance its quality.
Gem squash seeds should be sown during the warmer months in temperate climates, while in tropical zones, it is advisable to sow during the cooler months to reduce fungal issues. It is essential to keep the soil moist but not waterlogged, as this can cause the seeds to rot. Watering the plants deeply once a week is sufficient, ensuring that the leaves stay dry to prevent fungal diseases.
The spacing of gem squash seeds is crucial to allow for the sprawling nature of the vines. As the plants grow, they will spread out, and providing them with ample space or a trellis to climb can help manage their growth. With proper care and spacing during sowing, gem squash plants can thrive and provide a bountiful harvest.
