DIY feed that plants love but pests hate

This ‘plant feed with added benefit’ is recommended by Nancy Birtwhistle in The Green Gardening Handbook. It comes with a smell warning!

Plants love this liquid feed even though it smells awful to us. When I decided to add a little clove-bud oil I thought it smelled even worse! Plants are able to absorb essential elements through their leaves (foliage). After reading that plants love a nettle feed, and that clove-bud oil is an insect deterrent, I made this mix because I wanted to give my veggies an organic feed while at the same time trying to keep butterflies off my cabbages (it not only repels butterflies and other flying insects, it also controls aphids).

Makes about 500ml spray

YOU WILL NEED:

Rubber gloves

Scissors

60g nettles, leaves and stalks

Clean, old plastic tub with a lid

Old fine tea strainer

1-litre bottle with spray attachment

1-2 drops eco-friendly washing-up liquid

6 drops clove-bud oil

Wearing gloves, harvest the nettles with scissors. Select the young leaves because they contain more nitrogen that is quickly broken down in water. The leaves need to be 5-7cm long. Pop them in a plastic tub that has a lid. I buy my bicarbonate of soda in 5kg tubs and this container, complete with handle and lid, is perfect. Pour over the cold water (or rainwater), stir and push the nettles into the water using a gloved hand. Pop the lid on and leave outside and forget about it for at least a week (two weeks is even better), stirring maybe once or twice during that time.

When ready to use (and I suggest you do this outside), take off the lid, give it a stir and the smell will send you reeling – it really is awful, but plants love it! Strain off the leaves, using simply the lid as an aid, then strain again using an old fine tea strainer (the nettles will be a welcome addition to the compost heap). Fill the spray bottle with the foul-smelling liquid, then add the eco-friendly washing-up liquid and clove-bud oil. Give it a good shake then spray away!
