The goldenrod or golden rue (Solidago) originally comes from North America, but has been widespread in Central Europe for many centuries both as a rampant, wild weed and as a cultivated ornamental plant. Small, bright yellow cup flowers appear on dense, terminal panicles between July and September. The clump-forming, upright perennial can grow between 30 and 200 centimeters high, depending on the variety.
How to plant goldenrod correctly?
To plant goldenrods successfully, choose a sunny location with well-drained, moderately nutrient-rich, loamy-sandy soil. Plant goldenrod in late spring when danger of frost has passed, observing planting spacing, which depends on the variety.
Which location does the goldenrod prefer?
Goldenrods prefer a warm and sunny location, but often thrive in light shade. In places that are too dark, the flowers are not quite as lush.
Which substrate is best for goldenrod?
The perennial prefers a permeable, moderately nutrient-rich and loamy-sandy soil. Soils that are too lean or heavy can be improved by mixing in sand or gravel and clay powder.
When is the best time to plant goldenrod?
Since the golden rue is quite sensitive to frost, you should not plant it out too early in spring. It's best to only put the perennial outdoors from mid to late May, as soon as the risk of night frosts is lower.
At what planting distance should goldenrods be planted?
The ideal planting distance depends on the specific type and variety of golden rue. Of course, small cultivars require significantly less space than the giant goldenrods, which can grow up to 200 centimeters high.
How can goldenrod be prevented from overgrowing?
On the one hand, you can prevent goldenrod from becoming proliferative by planting non-proliferative varieties. It is also recommended to leave the root ball in the pot when planting or to bury a root barrier/root barrier.
How to propagate goldenrod?
The goldenrod reproduces itself very quickly through seeds and root runners. In addition, perennials that have become too large can be divided in spring.
When does goldenrod bloom?
Goldenrods bloom between July and September.
Good neighbors / Bad neighbors
Good planting partners are, for example,
- summer blooming asters
- Fine jet (Erigeron)
- Scabioses (Scabiosa)
- Sun Bride (Helenium)
- Montbretia (Crocosmia)
- Feather grass (Stipa) and other grasses
Tip
The tall varieties in particular need support, otherwise they will break off. Otherwise, goldenrods are good cut flowers that last a long time in the vase.
