Location and ground for forget-me-nots
The forget-me-not thrives in both sunny, partially shaded and shady locations. It grows in almost every soil, but prefers moist, clayey and humus rich soils. The marsh forget-me-not likes to be very humid and should be cultivated on swampy soils and watered accordingly.
Planting and sowing
The seeds are sown, not too dense, from mid-June to mid-July, in trays, window boxes, in the field or in the cold frame. The seeds should be well covered with soil and kept slightly moist. The young plants can be planted in October at a distance of at least 15 centimeters. The self-propagating plant needs enough space to develop.
Forget-me-not - care
Hardly any ornamental plant in the garden is as easy to care for as the forget-me-not. It needs a lot of water especially in the dry summer months and then needs to be watered daily. The casting should always be done from below. Before watering, the upper layer of soil must be slightly dry. Waterlogging should always be avoided. Since it proliferates by its many grains itself, excess seedlings should be removed in the spring and autumn, so that the individual plants have enough space. For fertilizing forget-me-nots, compost earth and organic fertilizers, e.g. Horn shavings very suitable.
In order to achieve a rich flowering in the following year, faded and dried plant parts should be removed after flowering at the end of autumn or early winter. If self-sowing is to be avoided, pruning must take place as early as possible; if you want to accelerate the self-sowing against, the cut is to be made as late as possible in the year.
use the myosotis
Forget-me-nots are particularly suitable as groundcover, water garden and rock garden plant as well as bordering of beds and borders. In combination with other spring flowers, e.g. Tulips, daffodils and primroses are particularly attractive. Also to juggler flowers, golden ricefish and marsh marigolds they fit perfectly. As the plant repels raspberry beetles, it is suitable as an underplant for raspberry bushes. The berries are then not attacked by maggots. The Caucasus forget-me-not repels snails and can also protect other garden plants from snail-eating.
Forget-me-not can be used very well for window boxes and tubs as well as cut flowers in the vase.
Forget-me-not overwinter and multiply
Forget-me-nots are hardy perennials. You can hibernate in place in the garden. Actually, they do not need special protection to survive the winter. In very cold winters, however, a cover with straw, leaves or brushwood is recommended.
According to its numerous flowers, Myosotis produces a large number of seeds and proliferates by itself. In spring and autumn, the plant can be multiplied very well by sharing. For this the plant is carefully dug out, divided and with sufficient distance (at least 15 cm) and planted separately again. Every single plant must have sufficient roots. Also, the propagation of ground cuttings is not possible when forget-me-not. To do this, take cuttings from the shoots, which are located directly above the ground, cut them off the ground and put them into a glass with water to form roots. Once sufficient roots have developed, the cuttings can be planted.
Diseases and pests
Forget-me-nots are rarely infested with diseases or pests. Care mistakes can lead to gray mold, powdery mildew and fungal diseases. Only in exceptional cases do aphids or spider mites occur in Myosotis. Gray mold and mildew are caused by too high humidity. The affected parts of the plant must be removed as quickly as possible, as these diseases spread very quickly and can be transferred to other plants. The diseased plant parts do not belong on the compost heap, but must be disposed of with household waste. For the control of aphids there are very good and effective, biological agents in the trade. Spider mites can also be controlled by such means. However, they are extremely persistent, so that the removal of the plant is recommended.
Worth knowing about forget-me-not soon
This attractive, early flowering forget-me-not is an early flowering summer flower and belongs in every garden and every balcony. The light blue flower tufts can be beautifully combined with other garden flowers. The native plant is relatively undemanding and easy to care for. It mainly needs enough water.

Forget-me-not has established itself today in most gardens and is often planted in pots or window boxes.
  • There are around 50 different species, both one and two years old.
  • The plant is native to temperate areas from Asia to Europe, Australia and New Zealand to North America.
  • The plant reaches a stature height of up to 40 cm, which, however, depends on the respective location.
  • It needs a humus rich, slightly acidic and moist soil. If it is dry, you must water it thoroughly!
  • The forget-me-not has hairy and alternate leaves, as well as sky blue and small flowers that sit on short stems.
  • A flower consists of a yellow center around which arrange five petals.
  • Initially, the flowers usually have a pink color that turns blue over time.

This fact is due to the cell sap in the plant: First, the sap is acidic, however, the plant absorbs metallic trace elements, the sap becomes basic and a color change of the petals is caused.


At the end of June to mid-July sowing should be done directly in the bed. Already at the end of August, the young plants reach a height of about 2 cm and at this time they should be pikiert, so that they have a distance of about 15 cm. Usually an increase also follows by the plants themselves, however, the descendants have from year to year a smaller growth. By early sowing the young plants get the necessary force until winter, but should be protected from the first frost, for example, with brushwood. In fact, only the time in which the plants grow up is critical. Too much moisture can cause gray mold or mildew.
