  • Jasmine officinale - liana with lignified stems, feathery leaves and white flowers, collected 5-6 pieces in a racemose inflorescence. The flowers are small - about 2.5 cm in diameter, but very fragrant. Flowering lasts all summer. It begins to bloom in adulthood. Likes some direct light and cool.
  • Jasmine multi-flowered Jasminum polyanthum is a liana with lignified stems, feathery leaves similar to the previous species. The buds are pink, and the blooming flowers are white or yellow (odorless), collected 15-20 pieces in a racemose inflorescence. It blooms in spring and begins flowering at a young age.

  • Jasmine primrose Jasminum primulinum - its creeping stems are tied to the support. The leaves are dark green, strongly elongated and pointed at the end, arranged in threes. The flowers are yellow, odorless, flowering in spring or summer.

Jasmine care

Temperature: normal, indoor in summer, does not like jasmine heat above 30 ° C. In winter, most types of jasmine prefer coolness, they are kept at a temperature of about 8-10 ° C, at least 6 ° C. Only jasmine Sambak is kept at a temperature of 17-18 ° C in winter, at least 16 ° C, preferably not higher than 22 ° C, at a higher temperature it is necessary to maintain high humidity.

Lighting: Jasmine is light loving, it needs good lighting for successful development and flowering, with protection from direct sunlight in summer during hot hours of the day. Jasmine grows well on the eastern windows without shading.

Watering: plentiful in spring and summer, the soil should be slightly wet all the time. Watering is more moderate in winter. Jasmine does not tolerate overfilling of an earthen coma, but stagnation of water in the roots should be avoided (roots easily rot from waterlogging). Water for watering jasmine should be warm at any time of the year and must be soft. It is better to use filtered water or boiled rain water.

Top dressing: During the period of active growth from April to August once a week, liquid fertilizer for flowering indoor plants (for example, "fertica" or "agricola" for flowering plants).

Humidity: Jasmine is regularly sprayed with soft boiled water in summer.

Transplant: Jasmine is transplanted in the spring, in March. Young plants are transplanted annually, old after 2-3 years. The soil is the 1 part of clay-turf, the 1 part of the leaf and the 1 part of the sand is for young plants. For old plants, clay-turf land is taken in 2 parts. Soil pH is slightly acidic, does not like jasmine of alkaline saline soils. Therefore, if you buy land in a store, choose the one that is intended for planting azaleas and rhododendrons, as well as coniferous crops.

Reproduction

Jasmine is propagated by cuttings in early spring and summer, as well as by branches. It is better to take one-year-old lateral shoots for cuttings, since the plants obtained from them will begin to bloom earlier. Cuttings with a lignifying stem are rooted in late summer. It is advisable to carry out rooting with soil heating.

Jasmine cuttings can be rooted in moist soil (a mixture of leafy and coniferous land) or in water by closing the cuttings with a plastic bag. Rooting takes quite a long time - more than a month, so phytohormones can be used for faster rooting.

Growing problems

The leaves are pale, the plant does not grow well, does not bloom - with a lack of lighting - jasmine should have a very bright place, with protection from direct sunlight at noon, as well as nutrients - carry out feeding during the spring-summer period. Leaves can also turn yellow when there is a lack of nutrients when the soil is depleted.

If there are spots on the yellowing leaves that look like punctures - dots or strokes, then the yellowing is caused by an attack on the plant by pests, ticks or thrips.

Jasmine does not bloom or blooms poorly if:

  • planted in soil containing lime and insufficiently acidic:
  • it is watered with hard water;
  • wintering temperature is too high;
  • too dry indoor air;
  • jasmine is not light enough;
  • lack of nutrients in the soil, in particular phosphorus and potassium, or an excess of some elements.

For example, feeding with nitrogenous fertilizers (for ornamental and deciduous plants) has a beneficial effect on the growth of green mass, but delays or stops flowering.

The leaves darken, brown at the edges or at the tips, then droop - the roots rot and die off from excessive watering. Overflow in cool, wet weather is especially dangerous. Water the plant after drying the top layer of the earth. Lack of humidity is not compensated for by more frequent irrigation.

Tick on Jasmine

Spider mite appears on indoor flowers at any time of the year, introduced with wind or other plants. Initially, small discolored spots appear on the leaves, if you look at the lumen of the leaf, point punctures are visible. Gradually, the leaves turn yellow and dry out. With severe damage in the internodes and from the back of the leaves, a web is visible.

Treatment: rinse the plant in soapy water - beat the foam with a sponge and wipe off each leaf, or dilute the soapy solution and rinse the entire crown (covering the ground with a bag). You can leave the soap for 20-30 minutes. Then rinse the foliage with hot water, the temperature is 40-45 degrees, according to the sensations of the hand it is hot. It is better to use green potassium soap, it is sold in flower departments.

Repeat the hot shower in 5-7 days twice more.

You can use drugs such as Fitoverm, Actofit, Agravertin, Acarin - at the rate of 10 ml per 1 liter of water, or Vertimek (1 ml per 1 liter of water). Processing must be repeated in 3-5 days - if the weather is hot or warm (26-24 degrees) and after 7 days, if the air temperature is 20 degrees and below, since these drugs do not kill tick eggs.

Hot showers and acaricidal treatments can be alternated.

The drugs Sanmait or Taurus are very effective at the rate of 1 g per 1 liter of water - a single treatment with thorough wetting of the crown destroys adult pests and non-nutritious stages (eggs).
