How to grow cucumbers from plug plants

How to Grow Cucumbers – Hints and Tips

Cucumbers are notoriously difficult to cultivate from seed. With our professionally grown plug plants you’ll be able to easily grow your own fresh, crisp cucumbers.

Greenhouse cucumbers are parthenocarpic, that is they produce fruit without fertilization of the flowers. We supply Femspot which is an all female F1 variety which has disease resistance and tastes great!

Transplant your plugs on the day you receive them if you can. Use a good quality , free draining multipurpose compost. 10cm pots (4”) are the best size to use. If you are using old pots, make sure you sterilise them first to remove any pathogens. We find Jeys Fluid to be the best, if you can’t find any, give them a good wash with warm water and soap.

 Fill your pots with compost up to about 1cm below the rim. Don’t compact the compost in the pot. Make a hole in the centre roughly the same size as the plug plant. Handle the plant gently by the leaves or root ball place in the hole, minimising compost compaction below the plug. Try to make sure the surface of the plug
is not buried Firm lightly around the plug.

Just as with  tomato plants, you can grow cucumbers up canes in a grow bag. Make sure they get enough compost for their roots by using grow pots in the grow bag ... or big pots (about 9”) with the bases cut away and planted into the bag. This makes them easier to water and feed ... and you’ll get healthy growth from your cucumber plants if you can keep them constantly watered and feed when the first fruits start to appear.

Plant Care
Watering and feeding should be carried out on a ‘little and often’ basis according to the requirement of the crop.  However do avoid letting the plants run dry. This doesn’t mean you can drown your plants once a week and leave your plants standing in water and think you’ve down a good job! What you’ll need to do is ensure the soil your plants are growing in remains moist but not water-logged at all times – don’t water the plants rather water the soil or compost surrounding the plants – this will encourage the shallow roots to grow strongly. If possible, try to maintain  the green house temperature around16oC, and avoid cold draughts as cucumbers are susceptible. Apply coolglass to protect the fruit from the glare of the midsummer sun.

Pests and diseases to look out for:
A whole host of pests and diseases can attack Cucumbers under glass, but not  many are likely to trouble you. Whitefly, aphid and red spder mite will usually appear, and so will powdery mildew if the compost is dry and the air is moist. Keeping the compost too wet leads to root rot or botrytis. Monitor the pest population in the greenhouse using sticky traps.

Cut (do not pull) when the fruit has reached a reasonable size and the sides are parallel. Use secateurs or a sharp knife. Pick regularly – cropping will cease if you allow the fruit to mature and turn yellow on the plant.
