Goldenrod, goldenrue, goldenrod herb - the perennial, which grows up to 200 centimeters high and is very eye-catching due to its abundance of bright yellow flowers, is known by many names. Originally native to North America, goldenrod can now also be found in many European gardens. The plant does not need much care, on the contrary: goldenrods have a strong tendency to overgrow.
How do you properly care for a goldenrod?
Goldenrod care includes occasional watering during drought, organic fertilization at the beginning of the growing season, pruning after flowering and in spring, and protection for potted plants in winter. The plant is robust and hardy.
What is the water requirement of the goldenrod?
The golden rue tolerates short-term dry periods quite well, and when planted in the garden, it takes care of itself. You should only water the perennial in very dry and hot summers. Specimens in buckets or pots also need regular watering.
When and how often should you fertilize the goldenrod?
Planted goldenrods are provided with organic fertilizers such as horn shavings (€61.00 on Amazon) or compost at the beginning of the growing season, which are well incorporated into the soil. Potted specimens are either supplied with fresh substrate once a year or fertilized once or twice a year with complete liquid fertilizer.
Can goldenrod be cultivated in a pot?
Goldenrods are very suitable for growing in pots, but you should ensure good drainage - the plants, like so many others, cannot tolerate waterlogging at all.
When and how can you cut the goldenrod?
If you want to curb the uninhibited spread of goldenrod, you must cut the plants immediately after flowering. If the fruit heads are already very dry, it is best to put a tarpaulin or something similar underneath them, otherwise you will have to do a lot of weeding later. Another cut is carried out in the spring before sprouting, in which you remove dried parts of the plant.
What pests or diseases threaten the goldenrod?
Basically, goldenrod is a very robust plant that is rarely affected by diseases or pests. It is only susceptible to mildew if it is left very dry for a long time. However, excessive moisture and even waterlogging leads to rot and thus the death of the perennial.
Is goldenrod hardy?
Goldenrods are very hardy and generally do not require any additional winter protection. Specimens only cultivated in pots and tubs should be protected from freezing with a fleece or similar wrapped around the planter.
Tip
If your goldenrods seem weak and don't want to grow properly, this could also be due to an oversupply of nutrients or too frequent fertilization.
