Fruit and veg

On the forum: which fruit and veg varieties are you growing?

Greenhouse

  • Set up a capillary matting system to ensure plants have enough water if you're going away on holiday
  • Plant cold-stored potato tubers in large tubs in a greenhouse or cool porch, for harvesting at Christmas
  • Pour water over the greenhouse floor every morning during hot weather to increase humidity
  • Plant up pots with 'Paper White' narcissus bulbs for fragrant indoor displays this Christmas
  • Remove the lower leaves of cordon tomatoes up to the lowest truss, to let more light and air reach the fruits
  • Take leaf cuttings from succulents, such as echeverias, crassula and sedums
  • Start watering dormant cyclamen to bring them back into growth after their summer rest
  • Plant flowering bulbs, such as nerines, lachenalia and veltheimia in pots indoors, for autumn and winter colour
  • Look out for pests and diseases on greenhouse plants, and treat any you find immediately
  • Harvest tomatoes, cucumbers and chillies regularly to encourage more fruits to form
  • Tackle vine weevil infestations by watering pots with a solution of biological control nematodes
  • Shade delicate plants in the greenhouse to avoid sun scorch on hot days
  • Take leaf cuttings from houseplants, including begonias, African violets and Cape primroses
