Calla lilies and flag stone
Our house was surrounded by a wooden deck. On the south and east sides were beautiful, very tall, well established calla lilies. The deck deteriorated and was replaced by a flag stone deck. That was 10 years ago and the calla lilies have not come back. We suspect it has something to do with the rock. What can we do? Thanks.

You will need to plant fresh calla lily bulbs in the spring. After 10 years of no returns your old calla lilies are not coming back. Calla lilies do love damp, cool soil so you may be correct in that the flag stone has changed the growing conditions probably by heating up the soil. Don't plant the new bulbs too close to the flagstones. Keep them at least 12 inches from the warmth absorbing stone.
Keep growing,
