Growing Cucumber in Tasmania

Introducing Cucumber

Cucumbers are a delicious warm-season crop. They are best grown vertically in rich soil. Try to keep their leaves dry to prevent fungal diseases. In hotter parts of the country, it’s best to give them some afternoon shade to stop them getting sunburned, but in Tasmania, they’ll take all the sun they can get.

Classic Mistakes

Cucumbers are prone to fungal diseases, so try not to water their leaves. If you must water the leaves, do so in the morning, so that that can dry quickly as the day warms up.

Sunlight

Grow in: Partial Sun - Full Sun

Cucumbers in Tasmania need all the sun they can get.

Soil Preparation

Dig in some compost and well-rotted manure. Cucumbers are happiest in rich, well-draining soil. They’ll do well in almost any soil as long as it doesn’t become waterlogged, but the better the soil is to start, the less feeding they’ll need through the season.

Sowing Seed

Sow seed: All of October
Sowing depth: 10mm - 20mm

Start seeds indoors or under glass to make the most of the short growing season.

Cucumbers can be grown along the ground or vertically. If you’re growing them on the ground, then they’re usually grown on mounds to help with drainage. If you’re growing in raised beds, then the vines can also be allowed to trail over the edges of the bed.

If you’re planning on growing them vertically; train them up tee-pees or lattices. Space the plants according to the instructions on the package. Plant two or three seeds into each hole. Once the seedlings are up, thin them out and only keep the strongest ones.

Planting

Plant seedlings: November-January

Cucumbers are very sensitive to frost, so only plant them out once the frosts are over and the weather is consistently warm. It’s always a good idea to have some cloches on hand in case there’s a sudden, late, cold spell.

Take care when handling the seedlings and water them in well to help them settle in. Cucumbers can be grown along the ground or vertically.

Care

Train your plants onto the structure you have chosen. In some cases, you may need to tie the vines in at first to help them up their supports. Pinch out the growing tips to encourage them to branch out more.

Watering

Cucumbers need lots of water, but they do prefer the soil to dry out a bit between waterings. Where possible, water only the roots and take care not to wet the leaves. Cucumbers are prone to a range of fungal diseases and keeping the leaves dry and well-ventilated helps to avoid infection.

Feeding

Cucumbers are heavy feeders. Give them a balanced, organic fertilizer every few weeks.

Mulching

Give cucumbers a thick layer of organic mulch. This will help to keep their roots cool and moist. Lucerne, sugar cane and pea straw are all good options. Remember, you should only add mulch once your seeds are up and the plants are well established.

Harvesting

Harvest: 8 to 10 Weeks After Planting

Different types of cucumbers are harvested at different stages for their specific uses. Harvest your cucumbers as soon as they are ripe, Regular harvesting will encourage your plants to produce more. Use a sharp knife to cut the ripe cucumbers away from the vine.
