Lavender is a kind of flower that symbolizes love. its spike is slender and more beautiful. When it comes to flowering, it blossoms purple, which is seen from afar as a sea of flowers, and it has a unique fragrance. It is often used to make perfumes, or to make dried flowers to decorate the interior. No matter from the color or taste, it is irresistible. That being the case, you might as well keep a plant like this at home.

1. The breeding points of lavender:

1. Sowing seeds

The sowing time of lavender is generally spring, the warm area can be carried out in March-June or September-November every year, the cold area should be sowed from April to June, and it can also be sowed in greenhouse in winter, the germination time is about 14-21 days, and the optimum germination temperature is 18-24 ℃. Proper light is needed after germination, and weak light is easy to grow in vain.

2. Cuttage

Lavender cuttings are generally carried out in spring and autumn, and softwood cuttings can also be done in summer. The medium of cutting can be mixed with coarse sand of 2 ℃ and peat moss of 1 peat moss, which can take root in about 40 days under the condition of good drainage, keeping moist and 20-24 mol bed temperature. Do not use the terminal bud cuttings where inflorescences have appeared, because the flowering branches have aged and the rooting will adversely affect the future growth.

3. Ramet

The ramet propagation of lavender can be carried out in both spring and autumn, using 3-4-year-old plants and split with adult roots in March-April in spring, with bud eyes on each branch.

Second, the cultivation techniques of lavender:

1. Soil

Suitable for slightly alkaline or neutral sandy soil. Special attention should be paid to the selection of well-drained media, which can be mixed with perlite, vermiculite and peat moss. If it is cultivated in the open field, we should pay attention to the drainage of the soil, and the soil can be piled high into a bed before planting.

2. Watering

Lavender doesn't like the retention of water in the roots. After one-time watering, the soil should be fed again when the soil is dry. The surface culture medium is dry, the interior is moist, and the leaves wilt slightly. Water in the morning, avoid the sun, do not splash water on leaves and flowers, otherwise it is perishable and breeds diseases and insect pests. A continuous humid environment will cause the roots not to breathe enough air and grow poorly, or even suddenly die of the whole plant, which is often the reason for the failure of lavender cultivation.

3. Lighting

Lavender is an all-day plant, which needs plenty of sunlight and humid environment. The environment that can give full sunshine is better. Half-day sunshine can also grow, but flowering is rare. Summer should cover at least 50% of the sun and increase ventilation to lower the ambient temperature, so that although the growth is weak, it does not die. Lavender can grow well on flat land in winter and should be cultivated under full-day sunshine.

4. Temperature

Lavender is semi-heat-resistant, cool, warm in winter and cool in summer. The suitable temperature for growth is 15: 25 ℃. It can grow at 5: 30 ℃. The limiting temperature is above 35 ℃, which is higher than 38-40 ℃ for a long time. The top stem and leaf are withered and yellow. In northern China, dormancy begins when it is below 0 ℃ for a long time in winter, and the seedlings can tolerate a low temperature of-20 ℃ per square meter during dormancy.

5. Fertilization

Fertilizing can put bone meal in the basin soil as base fertilizer (used once every three months), seedlings can apply Huabao 2 (20murmur20), and then apply fertilizer with higher phosphate fertilizer such as Huabao No. 3 (10-30-20) after growing up. Apply light fertilizer. Lavender should not fertilize too much, or the fragrance will fade.

6. Pruning

Lavender flowers are the most abundant in essential oil, and flowers or inflorescences are mainly used. In order to facilitate harvest, some small inflorescences at the initial stage of cultivation might as well be leveled with large scissors, and the newly grown inflorescences are highly consistent, which is conducive to a harvest. Some varieties can reach a height of up to 90 centimeters, and this method is also used to make the plants low and make them more branched, blossom and increase the yield. After flowering, the plant must be pruned, and the plant can be pruned to the original 2umber 3, so that the plant type will be stronger and conducive to growth. Pruning in the cold season such as spring and autumn, generally pruning in spring, pruning in autumn will affect the cold resistance. Be careful not to cut the lignified part when pruning, so as not to weaken the plant and die.

Everything is wonderful, there is a praise mall in the flower school.
