SUSTAINABLE GARDENING
Soil
Feed soil with organic matter to nurture it:
No dig methods add 2-3” compost as a mulch on top each year
Don’t disturb mycorrhyzal fungi that allow plant roots to take up nutrients from the soil
Exclude light from very weedy areas so the weeds die off – black plastic, compost or other mulch
Water
Prepare for drought and heavy rainfall: climate change means we have more extreme weather events.
Feed your soil with organic matter to support it during extremes
Mulch to conserve soil moisture
Water mainly at planting or sowing
‘Puddling’ at planting gets them off to a good start – wet soil, allow to drain, then repeat before planting seeds or seedlings
Water less often with more volume
Collect rainwater for your plants rather than treated tap water
Consider a rainbox planter or rain garden --https://www.hkdtransition.org.uk/rain-gardens
Seeds and plants
Save seeds, swap with other gardeners. Swap plants.
Choose plants carefully for drier areas (drought-resistant plant guide from RHS on https://www.rhs.org.uk/advice/profile?PID=397
Bog gardens thrive in wet areas - https://www.rhs.org.uk/advice/profile?PID=356
Wildlife/bugs
Encouraging wildlife into your garden can help reduce the ‘pests’ that eat your crops:
Hoverflies, lacewings and ladybirds eat aphids – encourage beneficial insects by planting what they like. See https://www.gardenorganic.org.uk/beneficial-insects
Hedgehogs like slugs – their numbers have fallen by 30% in last 10 years so if you see one take care of it by creating nesting sots and hedgehog streets. http://www.wildlifetrusts.org/hedgehogs
Frogs and toads eat slugs and snails – a small pond or bog garden would be good for them
Protect newly planted seedlings with a collar cut from a yoghurt pot or plastic bottle – use many times
