Introduction to the Propagation method of Lavender

Feather leaf lavender is an all-day plant, but it must be cultivated in shade in hot summer to avoid sunburn. Because feather leaf lavender is a male sterile line, its pollen is underdeveloped, so it can not self-pollinate and produce seeds. Artificial propagation of feather leaf lavender can choose the method of cutting or ramet.

Feather leaf lavender

I. Cuttage propagation

Cuttings are generally carried out in spring and autumn. Softwood cuttings are also available in summer. The cutting medium can be mixed with the coarse sand of 2 stroke 3 and the peat moss of 1 stroke 3. The well-developed plants were selected, and the top buds of one-and-a-half-lignified branches with short and sturdy nodes and unheading were selected, and the cuttings were cut at the top 8~10cm. The cut of the cuttings should be close to the stem node and try to be smooth so as not to break the phloem. Remove the leaves of the bottom 2 sections, cut them in water for 2 hours and then cut them into the soil, and they will take root in about 2-3 weeks. One-year-old branches of 8~10cm can also be selected, which can take root in about 40 days under the condition of good drainage, keeping moist and the bed temperature of 20-24 ℃. 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. Plastic film cuttings, soil preparation to make beds. After pouring through the water, cover the film and cut it immediately. The depth is 5cm to 8cm, with line spacing 20~25cm. Pay attention to improve the ground temperature, promote the development of root system, prune and extend branches frequently, remove the ear of flowers in time, promote branches and cultivate strong seedlings. Plant spacing 60cm, row spacing 120cm. Water immediately after planting.

2. Separate plant propagation

It can be carried out in both spring and autumn, with 3-4-year-old plants and split with adult roots from March to April in spring, with bud eyes on each branch.

Is the feather leaf lavender poisonous? the culture method of feather leaf lavender

Feather leaf lavender (Lavendula pinnat), native to the Canary Islands, is the longest pure ornamental variety, used for cut flowers, flower or garden cultivation and aromatherapy. So is feather leaf lavender poisonous? How to raise feather leaf lavender? Let's take a look at it with the editor.

Is feather leaf lavender poisonous?

Whether lavender is poisonous in rainy night.

Feather leaf lavender (Lavendula pinnat), native to the Canary Islands, is very similar to Canary lavender, but the flower is more compact and darker. It is now widely cultivated all over the country.

1. Morphological characteristics

Plant height: feather leaf lavender plant height 30-100cm flowering: flowering all the year round, but the main flowering period is concentrated from November to May or June of the following year, and dormancy is stopped when summer is overheated.

Fragrance; the aroma of feather lavender is similar to the mixture of geranium and rosemary, but with a strong miscellaneous smell. Leaves are fragrant, but flowers have no fragrance.

Leaf flower: the leaf shape of feather lavender is bipinnately parted leaf with light fragrance; the leaf is opposite, the leaf surface is covered with powder, and the leaf color is gray-green. Plants spreading, luxuriant shrubs, flowers dark purple tubular florets, dark lines, upper lip more developed than lower lip, with 2 lips.

Florescence: the main flowering period of feather leaf lavender is from November to May or June of the following year, and stop blooming and dormancy when the summer is overheated. It can blossom all the year round in a warm and conditional environment.

Second, ecological habit feather

Leaf lavender likes sunshine, heat resistance, drought resistance, extreme cold resistance, barren resistance, saline-alkali resistance, cultivation sites need sufficient sunshine, good ventilation. The time from sowing to flowering (or harvest): 18-20 weeks. Lavender should be cultivated in large containers. But potted plants can choose pottery pots or smaller plastic pots to prevent excessive wetness. Large pots should not be used unless they have grown to a considerable size.

Feather leaf lavender can not stand the heat and humidity, if long-term waterlogging root rot will die. 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.

Culture methods of Lavender Leaf

Feather leaf lavender is a perennial small shrub, which can be used for about 10 years. It has extensive varieties, easy cultivation, sunshine tolerance, heat tolerance, drought tolerance, extreme cold tolerance, barren tolerance and saline-alkali resistance. The cultivation place needs sufficient sunshine and good ventilation. The time from sowing to flowering (or harvest): 18-20 weeks. Lavender should be cultivated in large containers. But potted plants can choose pottery pots or smaller plastic pots to prevent excessive wetness. Large pots should not be used unless they have grown to a considerable size.

Lavender can't stand heat and humidity and 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

Feather leaf lavender is 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

Feather-leaf lavender does not 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 persistent humid environment can lead to poor growth of the roots without enough air to breathe, or even sudden death of the whole plant, which is often the reason for the failure of lavender cultivation.

3. Lighting

Feather leaf 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. In winter, lavender can grow well on flat land and should be cultivated under full-day sunshine.

4. Temperature

Feather leaf lavender is semi-heat-resistant, cool, warm in winter and cool in summer, the suitable temperature for growth is 15: 25 ℃, and 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

Feather leaf lavender fertilization can put bone powder in the basin soil as base fertilizer (once every three months), seedlings can be applied Huabao 2 (20-20-20), and then apply higher phosphate fertilizer such as Huabao 3 (20-30-20). Apply light fertilizer.

6. Pruning

Feather leaf lavender flowers are the most abundant in essential oil, which are mainly used in flowers or inflorescences. in order to facilitate harvest, some small inflorescences in the early stage of cultivation might as well use large scissors to make the whole flat, and the new 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.

Reproduction mode of feather leaf lavender

1. Cuttage propagation

Feather leaf lavender is generally propagated by cutting. It can also sow and reproduce in spring and blossom in about two to three months.

2. Management methods

Nature is more heat-resistant, drainage sunshine must be good, too much light is easy to Lignification, but less obvious than other varieties, summer shade. The cold resistance is semi-cold-resistant, and it should be protected below minus five degrees Celsius in winter, not resistant to snow. Generally placed in a ventilated place, there is a risk of sudden death indoors or in a stuffy and wet place in summer.

Disease control of feather leaf lavender

Feather leaf lavender has few insect pests.

The disease of feather leaf lavender is mainly root rot, which has the highest incidence in high temperature and stagnant water environment. Prevention and cure method: irrigate the root with 800 times solution of carbendazim and chlorothalonil once a month, especially from June to October, pay attention to prevent stagnant water and keep the air dry.

Cutting Propagation method of Lavender

Cutting propagation time of lavender

The cutting propagation of feather leaf lavender is suitable for spring, autumn and winter.

Selection of cuttings of Lavender

To select healthy and strong branches, you can cut them from the third stem above the terminal bud.

Cutting Propagation method of Lavender

If there are flowers on the cuttings, cut them off first, leave the bottom pair of leaves, wet the medium and insert them into the cuttings. After cuttings take root, they can be directly planted in pots or planted in flower beds.
