Greenhouse Gardening Techniques


Greenhouses and other glass protection 
  1. Install an electricity supply in your greenhouse to give you light and power for watering systems and propagating units.

  2. Remove automatic window openers in the winter, as heavy frosts can damage the liquid reservoirs which operate them.

  3. Locate greenhouses where they will get plenty of sun in winter and spring, and where you can get to them without getting muddy feet.

  4. Grow a pot of basil in your greenhouse to repel whitefly. They don't like the smell.

  5. Keep your greenhouse warm in the winter and save on heating bills by lining it with bubble plastic. The bubbles should be against the glass, to form a solid layer of air.

  6. Make quick cloches with two sheets of glass and four clothes pegs. Put two pegs on each piece of glass, lean the sheets of glass together, and put a rubber band on each pair of pegs to hold them together.

  7. Fix up a clear polythene curtain to separate plants which need different growing conditions such as dry and light for tomatoes or shady and moist for cucumbers.

  8. Water your greenhouse in the morning. Evening watering leaves moist conditions overnight which encourage red spider mite.

  9. Grow vegetable crops in growbags or tubs rather than in the border soil, to avoid a build-up of diseases and pests.

  10. Make your own staging with trestle legs and planks or expanded metal.

  11. If you have children in your garden, choose a cheap plastic greenhouse until they are grown-up, or choose rigid plastic glazing rather than glass.

  12. For cheap adjustable greenhouse shades, use roll-up bamboo blinds.

  13. If using biological pest control methods in your greenhouse. Check with the suppliers whether you can use pesticides without killing the predators you've purchased.

  14. Treat wooden structural portions of your greenhouse with linseed oil every live years.

  15. Install a water supply in your greenhouse. Even if it is no more elaborate than a tap.

  16. Keep a tank in your greenhouse to bring water up to air temperature before using it on your plants. Mains water can be cold enough to shock tender plants in hot weather.

  17. If you heat your greenhouse by electricity, keep a small paraffin heater as a backup in case of power cuts.

  18. Ask yourself if you really need to heat the whole greenhouse, or whether a propagator would be sufficient to keep your favourite plants going through the winter.

  19. Make a cheap cold frame the Chinese way, by digging a pit, lining the sides with sheets of polystyrene, then laying a few bamboo canes across the top to support plastic sheeting for a lid. A layer of gravel in the bottom of the pit will absorb heat during the day and give it off slowly at night.

  20. Put cloches out on the growing area at least two weeks before adding plants or seed, to let the soil warm up. Cover the ends to keep out draughts.

  21. Cold-frames and cloches attract ants, who like to make nests in warm places, so sprinkle ant killer round the edges to keep them out before they damage your plants.

  22. Use plastic water-bottles as individual mini-greenhouses for tender plants. Cut off the bottom and push the bottle firmly into the soil over the plant. Pop a few slug pellets inside and put the lid on until the weather warms up.
