Squirrels don’t intentionally dig up newly planted bulbs, but that’s how it seems. Your bulbs gets moved up to the surface as the squirrel buries it’s feast. Protect pots and new plantings with a cover of small mesh chicken wire now. Remove it when new growth is poking through the soil in spring.
Watch out for mice, if cold enough they may unearth your bulbs for a snack.
Rake up leaves under roses to prevent black spot spores overwintering in the soil. Affected leaves have dark brown or black, often coalescing, blotches on both leaf surfaces. Prune out infected shoots and remove any remaining leaves before they fall.
