How long does lavender seed germinate?

The germination rate of lavender seeds is low. If the seeds are fresh, they can germinate in 14 days after being treated before sowing. If the seeds are not fresh and untreated, it is hard to say, maybe it will be sent in a month, maybe longer, maybe it will not be sent. You can rub the seed coat with a towel to remove the grease before sowing or soaking the seeds.

If the seeds are fresh and can be broadcast directly, you can also soak the seeds first. Soak the seeds in 30 or 40 degrees water, that is, the water that does not burn your fingers, for no more than 24 hours. Pour the soil thoroughly at once, then put the seeds on the soil surface and gently press them with your fingers to cover a lighter medium, about one centimeter, that is, twice the volume of the seeds. Then cover it with a film, make a few holes to breathe, put it in a sunny place, and keep the soil moist all the time. After emergence, uncover the film and bask in the sun more.

After soaking the seeds, you can also choose to sprout first and then plant. Find a flat container, plate, etc., spread a paper towel, make-up cotton, or a small towel, spray it with water, then put the soaked seeds on it, cover it with a layer of paper towels, spray it, put it in a plastic bag, make a few holes to breathe, put it in a warm place with sunshine, open it for about an hour a day, observe the seeds at any time, and find that the seeds are exposed and planted in the soil right away. the white part is the root. It's not a bud. Don't plant it backwards. First grow slowly in the dark, and then slowly see the sun.

How to grow lavender?

Lavender can't stand the heat and humidity, and it will die if it suffers from waterlogging for a long time. When planting outdoors, be careful not to let Rain Water sprinkle directly on the plant. After May, you need to move places where there is no direct sunlight, increase ventilation to lower the ambient temperature and keep cool, so that you can safely get through the hot summer. Pay attention to sunshine, moisture, temperature and patience.

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.

two。 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, suitable for growth: 15: 25 ℃, 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 (20 Murray 20 Murray 20), and then apply fertilizer with higher phosphate fertilizer such as Huabao 3 (20-30-20) after growing up. Apply light fertilizer.

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 use large scissors to make the whole flat, 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.

7. Common diseases:

When one-year-old seeding or cutting seedlings were damaged, the plant wilted, lost water, the leaf color was dim, and the top of the leaf branch bent and drooped downward, which was the most obvious in the budding stage. The light ones can recover at night, and the severe ones die in two or three days, the roots rot, and the stem ducts turn brown and show luster. The wilting symptoms of more than three-year-old seedlings appeared in the center or edge of the plant, gradually developed inward and outward, the branches wilted and died, and finally the whole plant died. the damage degree varied with plant age and variety. It usually begins in May and reaches its peak in July and August. The disease of lavender in France is serious, while the disease of 2-417 varieties in the former Soviet Union is mild.
