Have you got a compost heap going in your garden? That's the first and best way of keeping your soil fertile. More than one is even better, so that the rotted and 'brewed' heap can be used while you add to the second one.

Get hold of a load of horse manure if you can, and let it rot down. Then you can dig that in. That does wonders for all sorts of plants, particularly roses and othe 'hungry' plants. Don't use it fresh, though - it can burn the roots.

If you can't get any, you can buy packs from your Garden Centre, but obviously at a price.

Thank you that has been very helpful.

You're welcome. :-) Happy gardening!

If you are not going to plant until spring cover with mulch to stop weed growth.
