Cucumber (Cucumis sativus)   Edit Report inappropriate crop

If you combine greenhouse with outdoor or 'ridge' (although they no longer need to be grown on one) cucumbers, they can be adding crunch to your salads and sandwiches from the end of May until early October. Gherkins are small and warty and bred to be picked small but are otherwise the same as outdoor varities. They all need a fertile, moist but well-drained soil, a sunny position and, for the outdoor varieties, protection from winds.

Heated greenhouse

sow indoors sow indoors

Sow two seeds on their sides, 1cm deep in an 8cm pot. Germinate at 20 °C and remove weakest seedling when large enough to handle. Transplant into 13cm pots at the 2-3 leaf stage.

Between plants: 46cm
Between rows: 46cm

Plant two to a growbag or one to a 23cm pot, 46cm apart. Keep floor moist to maintain humidity and tempearture at around 15 °C. Train main shoot up wires or cane and pinch out tip when it reaches the top of the support, allowing two shoots to trail downwards. If not an all-female variety, remove all male flowers (those without swollen bases - mini-cucumbers). Feed fortnightly with tomato fertiliser once fruit begin to swell.

Cut young cucumbers regularly to encourage more fruit. If cucumbers are left to mature and yellow, cropping will cease.

Sow two seeds on their sides, 1cm deep in an 8cm pot. Germinate at 20 °C and remove weakest seedling when large enough to handle. Keep compost only just moist to avoid stem rot. Harden off two weeks before planting out.

<p>Plant out after all danger of frost has passed, using cloches in colder areas. Fill a hole 30 x 30 x 30cm with well-rotted manure or compost and soil and create a mound on top. Plant at the centre of this. Pinch out growing tips when plants have 5-7 leaves. DO NOT remove male flowers.</P><p>May be trained up netting if space is limited. Water around plants (not on top). Mulch with grass clippings, spent manure or even black plastic to keep the roots moist. Feed fortnightly with tomato fertiliser once fruit begin to swell. </p>

After all risk of frost has passed, fill a hole 30 x 30 x 30cm with well-rotted manure or compost and soil and create a mound on top. Sow 3 seeds 2cm deep in the centre of each mound and cover with cloches. Remove weakest seedling. Pinch out growing tips when plants have 5-7 leaves. DO NOT remove male flowers. May be trained up netting if space is limited. Water around plants (not on top). Mulch with grass clippings, spent manure or even black plastic to keep the roots moist.

Organic matter is the key (jamiemac - 22:31 19/09/2012) Report inappropriate tip
Curcubits (courgettes pumpkins cucumbers etc) are v. thirsty and hungry. Organic matter (compost well-rotted manure) is the key - dig it in mulch. Alternatively grow them on a near-mature compost heap before spreading it in the autumn.
