Solidago) is a robust shrub that thrives well on inexperienced gardeners. Of the undemanding Goldenrod, there are numerous game species and numerous breeding species, which differ mainly in size. This makes the plant genus Solidago in the garden versatile and thrives - depending on the species - both in the shade and in sunny places. It harmonizes very well with other perennials and sets in a perennial flowerbed by its golden yellow color beautiful accents.
- Name: Goldenrod (Solidago)
- Family: Asteraceae
- Growth form: paniculate, upright branches; lanceolate, dentate leaves
- Growth height: 20 - 200 cm
- Flower color: yellow
- Flowering period: July - October
- Location: sun or partial shade
- Winter hardy: yes
- Solidago virgaurea: The native wild form of the Goldenrod is Solidago virgaurea, which is predominantly found along edges of forest. In nature, the common goldenrod is very inconspicuous, as the soil often does not provide sufficient nutrients, so that they can form beautiful large flowers. The common goldenrod has a branched but very upright habit of few baskets. In the garden under good conditions, however, it is much more flowering and also produces beautiful large flowers.
- Canadian goldenrod: Visually appealing is the Canadian Goldenrod, which can reach heights of growth up to 2.50 m. Although it has much smaller flowers than the common Goldenrod, it has much more that stand out by their abundance.
- Goldenmosa: Very pretty flowers also have the different breeding forms such as the Goldenmosa, which has golden yellow glowing mimosa-like flowers. Comparable to the Canadian Goldenrod but with stature heights of up to 60 cm, the cultivated form is ray crown. It forms similar to the wild relatives in the upper part of flat Blütenrispen.
High-growing species are suitable as specimen plants, low species can be easily combined with other shrubs. The Common Goldenrod is, like other Solidago species, very modest in terms of location. It can also be in the shadow or partial shade and is suitable, for example, in the garden for shady locations, which should be loosened up with a light flowering color. However, breeding forms or the Canadian goldenrod prefer very sunny locations throughout. They also set slightly higher demands in terms of nutrient requirements and must be supplied with sufficient water. The soil should be loamy to sandy, as the Canadian goldenrod in nature preferably populated debris or wet or loamy trenches. Tip: The goldenrod should be planted in a perennial plant bed in addition to a pot, otherwise it spreads too fast and may displace other perennials.
- Fertilizing: Basically very undemanding. For a long time without many nutrients, but for a nice growth in the garden they should be occasionally supplied with fertilizer. The ideal fertilizing time is spring, when the perennials are supplied with organic fertilizer such as compost, guano or horn shavings. Easily incorporate fertilizer into the surface and then pour regularly and abundantly so that the nutrients get into the soil.
- Overwintering: Goldenrod are easily frost-resistant to -30° C and do not need to be specially protected in winter.
- Pruning: Slicing takes place immediately after flowering, which gives a chance of abundant flowering after an early flowering in the summer. If self-sowing is not desired, the perennial should be cut back after each flowering.
Once planted in the garden, the goldenrod is a permanent guest, which also likes to spread by self-sowing. If it is regularly cut after flowering, propagation is also possible by division. For this purpose, the perennial is carefully divided in the spring with a spade, whereby it is also rejuvenated.
In general, the goldenrod is not susceptible to any specific diseases. Longer periods of drought can cause problems for the goldenrod and it can form mildew on the plant. In this case, only the infected parts of plants must be cut and disposed of in the residual waste, since the fungus can not be transmitted through the compost to other plants.The Goldenrod usually survives a mildew infestation without major damage, only if there are growth problems or there is a high risk that other plants could also be attacked, should a plant protection product be used.
Tip: The goldenrod can also react due to over-fertilization with growth disorders. If in doubt, then simply the fertilizer should be adjusted until next year, because the plant usually regenerates itself easily.
frequently asked Questions
- Can the goldenrod be planted in the pot? - The Goldenrod is also suitable for cultivation in a pot. The substrate should be permeable and have a high content of sand. The pot can drain as a layer of gravel or coarse rock have. When cultivating in pots, however, it is important that the goldenrod is regularly fertilized and poured. In addition, it must be protected from frost in winter, so that the roots are not damaged. However, it is sufficient if the pot is simply buried in an empty bed around two-thirds. However, as the Goldenrod is growing fast, it should get a pot for itself. In addition, it must be regularly repotted when the vessel is too small, or must be divided and distributed over several pots.
- Is it better to buy the goldenrod than shrubs or sow them? - There is already a large selection of Goldenrod species at very reasonable prices in the specialized trade. Anyone who wants to fill a perennial plant bed with handsome perennials will be happy with just one plant, because the goldenrod grows very fast and can be divided again and again in the following years. To plant larger areas with goldenrod, the plant is not cut, causing it to self-seed.
- Is the goldenrod suitable as a cut flower? - The goldenrod not only looks great in the bed, but also in the vase. However, the cut should be placed as far down as possible, the stalk can then be shortened for the vase later. This leaves no unsightly remains and the perennial is motivated to new impulses. In addition, only inflorescences should be used for the vase, which are only recently blossomed or nearing bloom. Older inflorescences, however, wither away in the vase very quickly and like to leave their seeds on the table.
