Got any good permanent cures for lily beetle?
Also planting new raised beds with spent mushroom compost as the main soil. Would like suggestions based around orange/yellows lilies?

Hi there
We often advise on using Bayer’s Provado ‘The Ultimate Bug Killer’ Spray on the foliage. If you do not like using insecticides then spraying with diluted fairy liquid or crushed garlic in water. Crush a whole corm of garlic in a small pan of boiling water. Allow to cool, strain and put in a small container in the fridge. When using, dilute three parts water to one part garlic solution. Spray often, every few days, especially when it has rained. There is a garlic product available in garden centres and stores, but this is a much cheaper alternative.
Regarding the mushroom compost, avoid Orientals Lilies as these prefer acidic soil. Asiatics, Longiflorum Asiatics, Oriental trumpets and longiflorum lilies will do well in your raised beds.
