This year we have had a number of shrubs killed via cold winter. What do we do with a flax with leaves that have all dropped? If I cut them, will it grow? It's been in the garden for 6 years. Also, on the bay tree in a pot, the leaves have all turned brown. Will this grow back? The bay tree has been in a pot for 5 years.

We have had an abundance of flax flowers in our backyard. What should we do with the plants at the end of the growing season? Should they be cut down or left during the winter?
You can simply leave it as is to cut in spring or you may cut the dead growth back to the ground now. Either way is fine as the plant naturally goes dormant and will regrow in spring. Many people choose to leave the old foliage growth as extra protection during winter, however.
I have flax plants in a border planting and they get tall and floppy sometimes. The soil isn't particularly rich and they don't get a lot of water. When I have cut off the plant tops, the whole plant seems to die. If the stems are used for linen, surely the plant gets cut back for this use. What happens when the plants are harvested for linen making?

I have blue flax from High Country Gardens and the entire lower half of both my 3+ year old plants are covered with fine orange dots. It seems to be making the plants wilt. I am thinking fungus. What could it be? How would I identify it and treat it? Thanks so much!

Can Blue Flax perennials be split? If so, when is the best time of year to do so? If not, how can I get more plants from the one I have?
Blue Flax is difficult to divide, but some people have been successful at this. The best way to propagate this plant is by seed. Allow the flowers to go to seed; when the seedhead dries out it is ready to collect. Sow the seeds in the garden the next spring, or start seedlings indoors a few weeks before the last frost.
