When, how often and how?

Curb spread by pruning

Against the tendency of the golden rue to use root runners as well to spread quickly and over a large area, root barriers and similar measures help. However, goldenrods also have the habit of reproducing themselves just as successfully via seeds. In contrast, the only thing that helps is to cut off all inflorescences immediately after flowering - and before any infructescence has formed. If you do cut too late, it is best to cover the ground below the plant with a tarp or hold a bowl underneath. The main thing is that the seeds do not fall to the ground.

Goldenrod dangerous for allergy sufferers

It is true Goldenrod not poisonous, but their pollen often causes allergic reactions. Not only pollen allergy sufferers are affected, people with sensitive skin can also be affected. The sap can cause contact allergies or Trigger contact eczema. If you are sensitive in this regard, it is better to wear gloves when cutting. Those who suffer from hay fever, on the other hand, prefer not to plant the goldenrod.

Cut back withered shoots in spring

A second cut is made in spring when you remove the shoots that have dried out and frozen back over the winter. The right time for this cut is a mild, not too sunny day before the actual budding. Due to the goldenrod's high resistance to frost, it does not necessarily have to be frost-free on this day.
