If you’re living in a subtropical region, mid to late summer is a fantastic time to make the most of your garden. With warm temperatures and ample sunlight, many vegetables thrive during the subtropical summer. Whether you’re an experienced gardener or just starting out, this guide describes the 7 best vegetables to plant and grow during mid to late summer.
1. Sweet Corn
Sweet corn loves the warm weather and grows well during the subtropical summer. Plant corn seeds in blocks rather than rows to ensure good pollination. Keep the soil consistently moist and fertilise regularly for a sweet, juicy harvest in about 10-12 weeks.
2. Eggplant (Aubergine)
Eggplants thrive in warm, sunny conditions and are perfect to plant and grow in a hot climate. Choose a sunny spot and enrich the soil with compost before planting. Water regularly and watch as these vibrant, versatile vegetables flourish in the heat.
3. Chilies and Capsicums
Chilies and capsicums (bell peppers) are summer staples that love the subtropical heat. They are therefore one of the best vegetables to plant and grow during summer. These plants are relatively low-maintenance and can produce a continuous harvest if cared for properly. Plant them in a sunny spot with well-drained soil and keep them watered consistently.

4. Cucumbers
Cucumbers are fast-growing and perfect to plant and grow in a hot climate. They thrive in warm temperatures and require a sunny location with support for climbing varieties. Keep the soil moist and fertilise regularly for a bountiful harvest of crisp, refreshing cucumbers.
5. Zucchini (Courgette)
Zucchini is another prolific summer vegetable. Plant seeds directly into the soil and provide plenty of space for the plants to spread. Zucchinis grow quickly, and regular harvesting encourages continuous production.

6. Snake Beans (Yardlong Beans)
Snake beans are well-suited to subtropical summers and are incredibly productive. These climbing beans grow rapidly in warm weather, producing long, tender pods. Provide a sturdy trellis and keep the soil moist for optimal growth.
7. Pumpkins
Pumpkins are a summer favourite that require a sunny spot and plenty of space to sprawl. Plant seeds directly into the ground and enrich the soil with organic matter. With consistent watering and care, you’ll be rewarded with a hearty harvest in the coming months.
Tips for a Successful Hot Summer Garden
- Soil Preparation: Enrich your soil with organic matter, such as compost or well-rotted manure, to provide essential nutrients.
- Watering: Water deeply and consistently to keep the soil moist, especially during hot weather.
- Mulching: Apply mulch around your plants to retain soil moisture, regulate temperature, and reduce weed growth.
- Pest Management: Keep an eye out for common pests like aphids and caterpillars. Use natural remedies or organic pesticides to protect your plants.
- Succession Planting: Stagger your plantings to ensure a continuous harvest throughout the summer.
By planting these vegetables in January or February, you can enjoy a thriving garden and a bountiful harvest during the subtropical summer. Happy gardening!
I am an educator and passionate gardener and traveler. Throughout my adult life, gardening has been my passion, therapy, drive and source of purpose. Even as a child I had an intrinsic interest in plants and a desire to understand what makes them grow.
I distinctly remember the moment this began - my family was on one of our regular road trips from Hervey Bay; Australia. We were driving past a field of sugar cane. Dad pulled the car over and we cut a couple of sugar cane stems and brought them home for a treat. To be honest, I didn’t really like the taste, but I did want to try and grow it; and that is exactly what I did. It was then that my fascination, interest and passion for gardening and understanding plants began.
Fast forward a few years and I studied biological sciences and began what would be a 36 year career as a Biology educator. From this, I don’t only love gardening, but I also love helping others learn about gardening. I am also always looking for new ways to develop my own gardening knowledge. I like to think I am truly a life-long learner.
Fundamental to my beliefs about education is that learning is often best done as a part of a community - learning from others, and helping others to learn. It is this type of community that I hope iCultivate will be for its members - a community of gardeners, keen to share their gardening knowledge and wanting to learn about new ways to garden - a community built on the love of gardening.
