Snowdrops are the most beautiful messengers of spring among the spring flowers . They defy snow and frost and sprout already in February and March. Often, amateur gardeners wait impatiently for the snow-white flowers. But then the disappointment: it is already mid-March and the snowdrops do not bloom. A sure sign of care errors or disease. We explain what you can do to encourage flowering and what to consider when repotting bulb flowers.

Snowdrops do not bloom: dried out bulbs
The bulbs of the spring flower are placed in the ground at the beginning of the autumn season. Therefore, from mid-September they are available in garden centers. However, when buying them, you should pay extra attention to the fact that the bulbs are fresh. If they are stored for more than 2-3 months, they dry out and can very slowly form root system and shoots again. Therefore, they may not bloom in the spring. Fertilizing in the fall can not solve the problem either, because fertilizers promote sprouting, not flowering.
Snowdrops do not bloom: soil pH too low.
Snowdrops do best in neutral to slightly alkaline soils. The early bloomers do not like nitrogen. A common mistake many amateur gardeners make is to apply complete fertilizer to the flower bed. The special fertilizer can lower the pH of the soil. Because of the high acidity, the snowdrops cannot absorb the nutrients. As a result, growth is inhibited and flowering stops.
Snowdrops do not bloom: too much direct sunlight.
Snowdrops prefer an off-sun location. Especially if the site faces west or south and the flowers get more than four hours of direct sunlight a day, they can burn.
But too little light can also have a negative effect on the delicate flowers. Especially on the balcony, space is very limited. If houseplants are suddenly allowed outdoors in February, arrange them so that they do not cast shadows on the snowdrops.
Snowdrops do not bloom: too densely planted flower boxes.
Snowdrops need a minimum spacing of 20 cm. If the window box is too small, the flowers may root. Certain ornamental grasses and perennials can crowd out the spring bloomers and stunt their growth.
Early bloomers on the balcony: waterlogging
The snowdrops can not thrive waterlogging. Good drainage is therefore an absolute must. A layer of gravel or sand can loosen dense soil and make it more permeable.
Diseases and pests
Bulb flowers are rarely attacked by pests. If the winter was mild, slugs may crawl out of their hiding places earlier than usual and attack the bulb flowers. Also dangerous are certain fungi that multiply rapidly in waterlogged conditions and cause the disease gray mold.
Transplant snowdrops in March: Common mistakes
March, during the blooming season, is the right time to transplant snowdrops. This is when they are particularly hardy.
At the same time, many amateur gardeners commit a mistake and cut the flowers close to the ground. Actually, the bulb needs all the nutrients from the leaves, flowers and stems. The above-ground parts of the plant are cut back only when the flower withers and the stems dry up.
So plant the snowdrops in March, including the stems, flowers and leaves. Proceed as follows:
- Check the plants for diseases and pests. Diseased plants should be dug up and discarded along with bulbs and root system.
- Dig up the bulbs. Snowdrops form daughter bulbs in March, which must be separated from the mother bulb before transplanting.
- Loosen the soil, dig holes, and place the flowers 20 inches apart in the soil.
- Water the flowers.
If you want to repot the snowdrops, you should proceed similarly. However, in containers the bulbs are more sensitive to frost than in the flower bed. In any case, the potting soil should not freeze through. If there are several particularly cold days in March, you can move the tubs into an unheated room.
