By Bunnings Magazine / Jan 2026

Grow these fast croppers for patch-to-plate food all summer long.

There’s nothing better than harvesting fresh ingredients from your own garden to add to your plate. While some edible plants can take a long time to yield, these fast growing vegetables and greens will be ready for eating in a few weeks. Sow seeds for these easy to grow veg and get ready for a quick crop: 

  • Beans (Phaseolus vulgaris)
  • Zucchini (Cucurbita pepo)
  • Rocket (Eruca vesicaria subsp. sativa)
  • Radish (Raphanus sativus)

Tip: Check out our guide on how to plant seeds.

Bean (Phaseolus vulgaris)

This quick-growing plant comes in climbing varieties that need support, or compact bush types that don't. Sow seeds directly into rich, well-draining soil in a sunny spot, and provide a stake, trellis or cage for climbers. Water and feed regularly with an organic fertiliser suitable for vegies. Pick often to keep your plant producing throughout the season.

Zucchini (Cucurbita pepo)

A summer crowd-pleaser, this crop rewards with an abundance of glossy dark-green fruits in as little as six weeks from sowing. Once established, its vines can trail and spread, so provide stakes or a sturdy trellis to lift the fruit off the ground, making harvesting easier and reducing the risk of pests and diseases. Plant in full sun in well-draining soil enriched with organic matter.

Rocket (Eruca vesicaria subsp. sativa)

Packed with peppery flavour, this salad favourite produces tender, harvest-ready leaves within weeks of sowing. It thrives in full sun to part shade and prefers rich, well-draining soil. For a steady supply, sow small batches every few weeks. Snip leaves regularly to encourage fresh growth and prevent the plant from going to seed, which can result in bitter leaves.

Radish (Raphanus sativus)

This crunchy root vegie is the ultimate quick win for your summer garden. Sow it and in just a few weeks, you’ll enjoy a crisp, colourful harvest, with vibrant red, pink, purple or white roots that brighten salads and sides. Plant in well-draining soil with added organic matter and thin seedlings early to give each root room to grow.

Keep in mind…

  • Store all garden chemicals and products out of reach of children and pets. 
  • Planting seasons vary according to region; check with your local store.
  • After applying fertiliser around edible plants, delay harvesting for a few days and rinse well before cooking and eating.
