Feeding is useful, particularly as plants are establishing, and herbaceous beds and pots will require feeding throughout their lifetime. Blood, fish and bone products are great all-round feed, and bonemeal is ideal for plants requiring phosphorus and calcium.
Learning to live with some of our garden pests is also part of the journey; a nibble here and a scratch there is not going to be fatal. Plants are required to feed the insect herbivores that also live within our garden, most of which will never take enough to seriously damage the plant itself. It is important to remember that where you have pests, predators will soon follow! So, if you can bare to allow a little short term pest invasion, it’ll pay off in the long run because you’ll then get a healthy predator population too which will be far more effective than any chemical treatment. And it’s free!
