Ramsons problems — and how to fix them
Ramsons (Allium ursinum) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Aggressive spreading
It self-seeds and multiplies by bulbs into dense colonies that can swamp neighbours. Deadhead before seed sets and confine it to a contained woodland area.
Early dieback in dry sun
In sunny or dry sites the leaves yellow and collapse prematurely. Plant in moist shade so it completes its growth cycle.
Confusion with toxic look-alikes
Foliage resembles toxic lily-of-the-valley and autumn crocus when not in scent. Always crush a leaf to confirm the strong garlic smell before harvesting.
Allium leaf miner and rust
Like other alliums it can attract leaf miner and develop rust in crowded, damp plantings. Remove affected leaves and avoid overcrowding.
