The cut flower "forget-me-not" is a perennial herb of the blue snow family, which can be used for annual and biennial cultivation. The seedlings of precocious varieties treated with low temperature should be selected for annual cultivation, which should be planted from April to June, blossom in autumn, and then continue until the following spring. High temperatures in summer should be well shaded and cooled down, and heat preservation measures should be taken in winter. In the biennial cultivation, the seedlings were planted from October to December without heat preservation measures, so that the seedlings were induced by low temperature in winter and flowered in the following spring until the winter of the same year.

Sow:

Don't forget that my sowing is usually in September-January of the following year, the suitable temperature for seed germination is 20 ℃, and the temperature should not exceed 25 ℃. The seeds are light-averse. After sowing, the seeds should be slightly covered with soil and maintain humidity. Under the suitable temperature of 15-20 ℃, it germinated after 10-15 days. The sprouts should be ventilated after being unearthed, and the seedlings should be planted when they have more than 5 true leaves. It can also be sown in spring, but the florescence is delayed and shortened. Ramet and cuttage propagation can also be carried out during the growing period. The seedlings were planted in the garden at the beginning of November, and the distance between the seedlings was 30cm. Strengthen the management of water and fertilizer in the next spring to promote bud formation and flowering. After flowering, the fruit is harvested in time to prevent self-shedding, usually cutting the fruit sequence for cold drying and threshing.

Colonization:

Forget-me-not like to dry, the soil layer is deep, loose and breathable, slightly alkaline sandy loam, such as mature organic fertilizer and slow-acting compound fertilizer, turn evenly into the soil after application; the row spacing of planting plants is 30 cm × 40 cm, and the planting depth is slightly higher than that of the root neck. The temperature should be kept below 15 ℃ for 2 months after planting, so as to facilitate the plant to pass through the vernalization stage and facilitate normal growth and flowering.

Watering:

Do not forget me like dry and well-drained environment, avoid waterlogging. The amount of watering should be properly controlled during the whole growth period, otherwise it will lead to the decline of flowering quality and yield. Forget-me-not like dry, like the soil layer is deep, loose and breathable, slightly alkaline sandy loam. Usually watering needs to pay attention to "no dry, no watering, watering thoroughly".

Fertilization:

The total amount of fertilization during the growing period, of which 70% of nitrogen and potassium were used as base fertilizer, 30% of which were used as topdressing, and all phosphate fertilizer was used as base fertilizer, generally once a season. Topdressing potassium fertilizer and boron fertilizer at flowering stage are beneficial to improve the quality and yield of cut flowers. Therefore, forget-me-not planted in spring and summer, when the seedlings are not treated with low temperature, it is necessary to postpone the time to enter the greenhouse to fully accept the low temperature and complete the vernalization.

Fixed:

In order to produce high-quality forget-me-not cut flowers, it is usually necessary to draw a net to fix the flower branches, using a nylon net of 25cm × 25cm or 30cm × 30cm, 20cm and 30cm above the ground, before the plant is bolting.
