I’ve never done this. I have quite a lot of beds due to the layout of the back garden, I’ve spent quite a lot of money on plants over the last few years, and I think my garden does quite well. It would no doubt do better if I improved the soil or fed the plants, rather than just watered when the garden needs it. I have a mix of the normal stuff - shrubs, perennials, not much that requires ericaceous feed or compost.
I have a compost bin, but it doesn’t produce much compost, maybe enough to be able to cover 5% of the whole beds area.
So what should I do please? Does the whole garden need to be mulched (have I left it too late if it does?) or is it ok just to feed (and if so, when and how frequently)? I have liquid tomato feed and liquid miracle gro.
