  2. 2. How does it differ fromother forms of gardening?In a conventional vegetable garden,each type is planted in rows orpatches. Usually similar species aregrouped together, such as brassicas,beans and peas and so on. Plants ofthe same or similar species competefor the same nutrients, and are anattractive habitat for pests of thatplant. Usually, the patches arerotated every year to prevent thebuild-up of pests and diseases and soas not to deplete the soil ofnutrients.

Plants that are known to get on well together are combined in the same bed. There areIt’s this simple: some tried and tested combinations, such as onions,1.

  5. 5. Or you can design a polyculture around oneor two crops that you want a lot of, choosingother plants that support your main crop orat least dont set it back in its growth. The polyculture introduced in this bookletproduces mainly leaf and root crops. You canalso develop combinations around other cropssuch as tomatoes, squashes or potatoes.Materials needed:SeedsSeedlings - grown indoors in advance of planting outCompostFine mulch - well rotted leaf mould is ideal; keeps moisture and adds fertility Planting the seedlingsWood ash, seaweed, rock dust - provide vital plant minerals 3) Planting The best time to plant your polyculture in theLiquid manures - another way to provide open is after the frost has passed, around mid- nutrients throughout the season May for most of Britain.

  7. 7. Looking after the mixedvegetable gardenOne week after sowing, mustard, radish,fenugreek and onion bulbs have started togerminate. The pre-grown seedlings have alsoestablished themselves. If you have achieved a very dense ground cover you can be quite drastic with your thinning, even using garden shears! Six weeks after sowing, production is increasing and there is no bare soil. Broad Day 7: A first flush of growth is starting leaf mustard, coriander and lettuce can be to cover the ground harvested, along with the first radishes.

  8. 8. Gaps in groundcover can be filled with mulch,The mixed vegetable plot should be easy to in this case with strawmaintain. The dense planting and the layerof mulch help conserve moisture and keepdown weeds, so the need for watering andweeding is minimised. The maintenance of the mixed vegetable bedcan be compared to that of a woodland or aforest garden. Always thin the ground coverand early crops when the later crops need morespace, and always try to maintain a “canopy” ofleaves to give no chance to the weeds.4 months: The initial groundcover has gone and Understorey of ruby chard and onions longer lasting crops have closed the canopy under a "canopy" of broad beans Mixed Vegetable Gardening8
  9. 9. 5) Harvest!So all you have to really do isharvest. If you dont harvest, theplants will grow too densely, go“leggy” with tall, thin stalks andsmall leaves. This means that theywill loose productivity and run toseed early. So you have to makesure that you always pick enoughto give other plants a chance tocome through. The space left by aharvested plant will be quicklytaken up by its neighbours. Thisway, there is never any empty spaceor bare soil.
