So, one year on and I have not done the wheel any justice with the choice of plants. Weirdly... some sections have grown better than others (all sections started out identical). If I was to totally replant, what would you advise please?

Alpines need an acid soil. Herbs may be any type of soil lover. Plant herbs of the type that have done well.

I would think that the stuff like rcket and lettuce would be the best to grwo in such a wbeel. Salad Wheel or something. You only need to grow herbs for one season and that will supply you with enought o last for years.

Salads like rocket or something cost a bomb in Sainsburys. A small pt of herbs last for ever.

I don't have acid soil... maybe that's why things haven't done so well. I've steered away from herbs because they would possible conceal the inner wheel. Someone has suggested sedums, which I'll have a go at.

Thank you

To help your plants, remove the shingle and add special compost that any garden centre will advise you to use for your alpines. Also buy the special feed too. Then cover again with the shingle.

By the way your wheel looks very professional. Just be a little patient and wait for those fantastic 'small' plants to do their bit.
