Train the main stem up a vertical wire or cane. Pinch out the growing point when it reaches the greenhouse roof. Pinch out the tips of sideshoots two leaves beyond a female flower (which has a tiny fruit behind it). Pinch out the tips of flowerless sideshoots once they reach 60cm (2ft) long.
Do cucumbers do well in a greenhouse?
For one, cucumbers hate the cold and frost, so they really thrive in a greenhouse environment. Another advantage is that you don’t need much room at all, and you can really take advantage of vertical space by using a trellis. Lastly, they simply grow quickly – so you don’t have to wait long until you can enjoy them!
Do you need to pollinate cucumbers in a greenhouse?
Greenhouse cucumber plants produce long, smooth fruits, much like the ones you find in the supermarket. These plants don’t need pollinating – in fact, you should remove any male flowers to prevent pollination happening or the fruits will end up bitter.
What is the best way to grow cucumbers in a greenhouse?
Sow cucumber seeds on their side, 1–2cm (½–¾in) deep, in small pots. Keep them at 21°C (70°F) in a heated propagator or on a warm sunny indoor windowsill. Sow from mid-February to mid-March if you’ll be growing them in a heated greenhouse, or in April if you have an unheated greenhouse.
When can I put cucumbers in an unheated greenhouse?
April
Cucumbers are raised from seed. The seed for plants to be grown in a heated greenhouse is sown during February to March and for growing in the unheated greenhouse during April. For quick germination maintain a minimum temperature of 70F/21C.
How long do greenhouse cucumbers last?
Cucumbers are grown as an annual, which means that the plant does not regenerate after the growing season. Once it has lived out its life span of roughly 70 days, the plant dies and cannot be regrown.
How do you train cucumbers to string up?
String training cucumbers is done exactly the same way it is with tomatoes. Just run hang a line of string from something towards the ground and as the cucumber plant grows, wind it firmly around the string. They support each other. Like a hotdog and mustard.
How many cucumbers do you get per plant?
Depending on who you ask, a healthy cucumber plant can be expected to produce 10 large cukes or 15 small ones within a harvest period of about three weeks.
Can you grow cucumbers in a greenhouse year round?
Greenhouse Heaters will help you achieve the required warmth your cucumbers need in those freezing periods. This way you don’t have to think about frost dates and are able to grow them throughout the year.
Why is my cucumber plant flowering but not producing cucumbers?
A cucumber plant will flower but produce no fruit if there is a lack of either male or female flowers on the plant. A lack of fruit will also occur due to poor pollination. Growing conditions (such as temperature, weather, and nitrogen levels) also affect pollination and flower production.
Should I remove male cucumber flowers?
If you allow the male flowers to develop and pollinate the female flowers, the fruits that develop will leave you with a nasty aftertaste as the seeds contain a bitter compound called cucurbitacin. So make it a regular job to remove male flowers and keep your fruits seed-free and sweet.
Do cucumbers need something to climb?
Cucumbers do best if they can climb instead of spread over the ground. The tendrils of the vines will grab fences, string, wire trellis, or tall cages so that the vines climb the structures.
How do I encourage my cucumbers to climb?
Cucumber vines will climb naturally, but you may need to help them out. Some might stay on the ground and venture over to neighboring plants. In this case, gently wrap the vines around the trellis. If they won’t cooperate, loosely tie the vines to the trellis until the tendrils start to hang on.
Do cucumbers climb or crawl?
Cucumbers naturally want to climb, but, often in the home garden, we don’t provide any support and they sprawl on the ground. One of the greatest advantages of cucumber fences is the fact that they save a significant amount of space in the garden by allowing the cucumbers to follow their climbing nature.
What is a natural fertilizer for cucumbers?
A mix of seed meal, lime, bone meal, and kelp meal. All materials are derived from nature and are available in most garden centers. Homemade fertilizer will not burn Cucumber plants. Combine the ingredients in a large bucket or container.
How often should cucumbers be watered?
Cucumbers perform best with regular, deep watering once a week or so and with more frequency if the weather is very hot for a period of days. Inadequate or inconsistent moisture can cause oddly shaped or poor-tasting fruit.
What do you feed cucumber plants?
When your cucumbers start to flower, feed weekly with a high potash fertiliser, such as a liquid tomato food. Cucumbers bear male and female flowers and in the greenhouse, you will need to remove the male ones, as pollination can make the fruits taste bitter and be full of seed.

Quick Guide to Growing Cucumbers
Space cucumbers 36 to 60 inches apart (12 inches apart for trellised plants) in an area with abundant sun and fertile, well-drained soil with a pH of 6.0 to 6.8. Improve native soil by mixing in several inches of aged compost or other rich organic matter.
Can you grow cucumbers in a greenhouse in winter?
