As beautiful as the goldenrod - often referred to as goldenrod or goldenrod herb - appears with its lush yellow flowers, the plant can become very tiring after a while. Goldenrods are extremely hardy, very robust and basically feel at home in almost any location - and also have a strong tendency to proliferate. For this reason, pruning immediately after flowering is particularly important, otherwise you will be wasting your time weeding out young plants.
The goldenrod is also wonderful as a cut flower
Contain spread by pruning
Root barriers and similar measures help against the tendency of the goldenrue to spread quickly and extensively by means of root suckers. However, goldenrods also have the habit of propagating themselves just as successfully via seeds. On the other hand, the only thing that helps is to cut off all the inflorescences immediately after flowering - before any fruit stalks have formed. If you happen to cut too late, it is best to cover the ground below the plant with a tarpaulin or hold a bowl underneath. The main thing is that the seeds do not fall to the ground.
Goldenrod dangerous for allergy sufferers
Although goldenrod is not poisonous, its pollen often triggers allergic reactions. Not only pollen allergy sufferers are affected by this, people with sensitive skin can also be affected. The plant sap can trigger contact allergies or 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 goldenrod.
Cut back dead shoots in spring
A second cut is made in spring when you remove the shoots that have dried up 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 high frost resistance of the goldenrod, it does not necessarily have to be frost-free on this day.
tips
Goldenrods are also great as cut flowers as they last a long time in the vase.
