Pruning advanced ornamental trees. Now's the time... Generally speaking an ornamental tree is one that is grown for its decorative looks and not for food. Winter is the perfect time to prune deciduous ornamental trees, as their structures are dormant. Inside the tree though, important processes are underway.
Tall grasses planted close to structures can pose a hazard during the winter. The foliage does dry out and can be flammable. If ornamental grass grows near your house, cut back the foliage in the fall. It will grow back in the spring. Keywords: ornamental grass care, grass winter care, winter ornamental grass.
