Green Manures for Home Gardens

Natural Green manures are fast-growing plants sown to cover bare soil. Often used in the vegetable garden, their foliage smothers weeds and their roots prevent soil erosion. When dug into the ground while still green, they return valuable nutrients to the soil and improve soil structure. Our Green Manure varieties have been selected for their highest nutrients values for any garden specially designed for New Zealand's climate Conditions.
  • Red clover is an aggressive, nitrogen fixing plant which is an effective weed suppressor. Good for improving and aerating soil structure. A short term alternative to White Clover, will usually last for two years
    An aggressive plant, providing a large mass of green vegetation
    Fixes large amounts of atmospheric nitrogen which is released once ploughed in
    Large tap root which penetrates deep into the ground, improving soil structure.

  • Lupins are probably the best nitrogen fixers of all the Legume family. Maximum soil improvement will be achieved if the entire growth is turned under prior to full bloom when the nitrogen levels are highest. Though the blooms are so pretty you can always leave one or two to flower! 90cm

    The planting of seeds for "green manure" is one the best, most ecologically friendly ways to improve the quality of your soil. They will add nutrients and organic matter, naturally improving all soil conditions, helping to suppress weeds and even protecting the soil from erosion by adding structure.

  • Phacelia Tanacetifolia is a quick growing hardy annual green manure that germinates at low temperatures. It will grow up to 1m in height and is tolerant of cold temperatures and may over-winter if it's not too cold. It suits most soil types but is particularly good in dry ones.

    Phacelia does not fix nitrogen but is a very rapidly growing annual nitrogen holder. It is particularly good at attracting bees, hoverflies, and wasps.

    Phacelia has beautiful scented purple/blue flowers, new seedlings are generally ignored by slugs and once grown will produce dense fern-like foliage. It smothers weeds and has an extensive root system that improves the soil structure. However, it does self-seed very easily so if it is used as green manure dig in before flowering or cut down and compost the foliage. It flowers from 6-8 weeks from sowing for a period of 6-8 weeks.
