What do you do with perennials in autumn?

Prune clump-forming perennials
Reduce clumps of perennials such as hardy geraniums, astrantias and alchemilla to ground level during autumn. Use secateurs to cut away all the dead foliage and tidy up the plant ready for winter. All perennials and grasses that die back can be tidied up in this way during autumn.

Can neem oil kill plants?

Neem oil might kill some plants, especially if they are young and if the oil is applied too heavily. Test a small area of the plant and wait 24 hours before applying it all over. Apply neem in the evening for outdoor plants and out of direct sunlight for indoor plants to prevent leaf burning.

Can rust be stopped?

Whenever you get iron, water and oxygen together, you get rust. So the best way to prevent it is to keep them apart; that's what paint does, or the spray-on wax and oil coatings that the car protection companies sell. Keep your tools dry; wipe down your bike after a ride; keep the water away and it can't rust.
