Gem squash

Cucurbita pepo var. Gem Squash 'Rolet'

Gem squash (Cucurbita pepo var. pepo) is a variety of summer squash that was domesticated from two wild varieties; C. texana found in the southern and central United States and C. fraterna found in Mexico. 'Rolet' is a small round squash with a dark green skin and pale yellow to green flesh, popular to use in many vegetable patches. It can be picked mature (the skin has hardened) or when still young with a soft skin.

Most squash cultivars will be ready to harvest about 8 -12 weeks after sowing. Remove the squashes with a 20 - 40 mm stem using a sharp pair of secateurs. Young 'baby' squash can be eaten with skin and pips!


Sow seeds in situ in spring after the last frost date. Plant about 2 cm deep and 60 - 90 cm apart, angle the pips to allow water to drain. It takes 7 to10 days to germinate.

Companion plants

Some vegetables inter-planted with your summer squash can repel these pests. Radishes, repel squash vine borers and cucumber beetles, while garlic repels aphids. Planting your squash at the base of maize plants can "disorients" the squash vine borer. Radishes attract flea beetles to their foliage and away from your summer squash. Summer squash benefit from being planted with any type of bean or pea, as these fix nitrogen into the soil, which is taken up by the squash roots. Squash is often planted with beans and maize as part of a traditional "three sisters" garden. Maize provides a support for climbing beans, squash, with its prickly leaves, keeps mammal predators away from developing maize, and beans provide nitrogen to both plants. Maize also has the benefit of producing a lot of pollen, which attracts more bees to pollinate your squash blossoms. Borage, an annual herb, attracts bees for pollination, and its leaves can be mulched around the squash plant to help put calcium back into the soil to prevent the calcium deficiency that causes blossom-end rot. Sink a pot of mint near your squash plants to draw away aphids. Seed orange and yellow nasturtiums around squash and throughout your garden as they draw away aphids, cucumber beetles and whiteflies, among many other pests. As a bonus, the blossoms are edible, with a sharp radish-like taste. Dill is also a good companion to squash as the herb is said to repel squash bugs as well as aphids and whiteflies.
