Do you have Comfrey popping up everywhere like I do? This is part of the borage family and makes a great fertiliser for your plants.
It is rich in potassium, nitrogen and phosphorus so can be used for a large variety of flowering and fruiting plants including tomatoes, peppers and potatoes.
Avoid using comfrey fertiliser on seedlings, root vegetables and leafy salads and herbs.
To make comfrey fertiliser just place the leaves into a tub (you can weigh them down with a brick) and cover with water. Leave for 3-6 weeks (it will be really stinky) then add to your watering can at a ratio of 1 part comfrey 10 parts water. It should resemble weak tea when diluted.
