Jasmine - Jasminum polyanthum

Jasmine (Jasminum polyanthum) - USDA Zone 9-11. It is generally a woody shrub, climber or a trailer with two hundred species mostly from Asia, Europe and Africa. It is native to tropical and warm temprate regions. It reaches to a height of 10-15 feet, growing approximately 12-24 inches per years.

Jasmine leaves are either evergreen or deciduous. The leaf arrangement is opposite in most species, leaf shape is simple, trifoliate or pinnate with 5-9 leaflets, each up to two and half inches long. Some are yellow in color while most of the species bear white flowers which are of one inch in size. Flowers in the olive family, Oleaceae, usually have four corolla lobes but Jasmine is an exception having five or sixes lobes. Petals have strong and sweet fragrance. Flowering takes place in summer or spring, usally six months after planting.

Jasmine Growing Conditions

Jasmine prefer full sun to partial shade and a warm site. They grow well in moist, well drained, sandy loam to clayey garden soil with moderate level of fertility. Adding of leaf molds to the soil makes it better for the growth of the plant. Mild fertilizer should be applied during spring.

Plenty of water should be given during summer but this can be reduced during winter. If the plant is to be grown indoors, then bright indirect or curtain-filtered sunlight should be given. In winter these indoor plant should be provided with full sunlight up to at least four hours a day. Temperature should range from 68-72 degree Fahrenheit at night, during day 50 to 55 degrees Fahrenheit will be an ideal range of temperature.

Jasmine Care & Cultivation

One or two initial ploughings are required to remove the weeds present in the land. It should be followed by the digging of pits at a size of thirty centimeters. Farmyard Manure (FYM) should be used to fill these digs.

Jasmine bushes should be planted during June to November. Plants should be kept at least eight feet apart in order to save the later growth of the plant from jamming together. Addition of fertilizer should be done from time to time. Phosphorous and Potassium should be applied in two split doses i.e once after annual pruning and again during June and July.

Younger plants should be tied with the stems to give a fairly heavy support. Tips of the plants should be pinched to stimulate lateral growth and frequent pruning should be done to restrain growth. If the vine is to be grown as a ground-cover then upward twining stems needs trimming. First irrigation should be given immediately after planting and subsequent irrigation at an interval of seven to ten days. Stem cutting and sowing of seeds are handy methods for the propagation of the plant.

  • Mild fertilizers are required for best growth.
  • Temperature must be controlled.
  • Jasmine needs regular pinching and shaping to control growth.
  • If not planted at a proper distance, plants will quickly become crowded.
  • Containerized plants should be planted in the fall.
  • Fully developed, unopened flower buds should be picked in early morning.

Tips to Grow Jasmine Indoor

Most of the indoor jasmine grown today, originated in tropical Asia and parts of China. The Jasmine sold for indoor houseplants, are tropical or subtropical vines - grown for their fragrance. Grow Jasmine indoors for their heady fragrance. We tell you how to succeed with growing Jasmine indoors.

All of the 'Indoor Jasmines' need bright light with at least four hours of direct sun per day. In spring and summer water the Jasmine regularly and fertilize every two weeks with a high phosphorus fertilizer to encourage good flower development (Tomato Feed is perfect for this - as is Phostrogen). Jasmines are best grown outside - in direct sun - for the summer. They can be pruned hard, and re-potted in the spring, after flowering indoors.

If you moved it into a pot with a diameter more than 2 inches larger than the pot it was in when you bought it I suggest that you move it back to a smaller pot or it will probably not bloom this winter when it should. If blooming plants are in too large a pot they do not bloom.

Jasmine is not an easy indoor plant; so don't get discouraged if you don't have immediate success. The immediate problem is the reduction in light when it was brought inside as indoor light is much less intense. Here is what you need to know about Jasmine care.

Light: Lots of bright light, but protect it from hot direct sunlight in midday.

Air and temperature: Jasmine does best in fresh air with good circulation. Indoors an open window in the warmer months is good or near a fan that circulates the air. The best temperature range is 60 to 75 degrees, although it will tolerate 50 to 85 degrees.

Watering: Water thoroughly as soon as the soil is dry down about a half inch. Jasmine does not tolerate being allowed to get dry. Leaves discolor quickly if the soil is kept moist for too long or allowed to get too dry.

Potting: If you have a blooming sized jasmine it will rarely, if ever need repotting. The roots must be quite potbound for jasmine to bloom. Repot only if the plant dries out within 2 to 3 days following a thorough watering.

Fertilizer: Use a 1-2-1 ratio fertilizer at half strength and only when the plant is healthy and putting out new growth.

Humidity: High humidity is not essential, but it helps.

Pests: Jasmine is a magnet for spider mites. Few jasmine plants escape periodic mite infestations. Check the undersides of leaves regularly for signs of mites and treat promptly and thoroughly with a soap and water spray.

Blooming: Jasmine usually bloom in January. Normally jasmine is cut way back to half its size following a winter bloom and then new growth is kept pinched back to promote fullness until August. Keep the soil moist and fertilize regularly when it is putting out new growth. In August, discontinue the pinching In October; give it completely dark nights and cool temps (40 to 50 degrees) to promote January bloom. Keep the soil a bit more on the dry side and provide lots of sun during the day. It is usually recommended that you do this for 6 to 8 weeks. This will help set the buds. After that normal room temperatures and a sunny window will suffice. This is a difficult regimen to provide. If you can only do this for a few weeks, it is better than not at all. If you cannot do it at all, your plant will remain healthy but it may not bloom quite as much. In any case do not fertilize during the winter months. In the late winter or early spring, prune the entire plant back by half. New growth will soon emerge. Flowers appear only on new growth.

Propagation: Jasmine can be propagated at any time, although early spring is the preferred time. Take tip cuttings with two to three sets of leaves. Strip the lowest leaves off the cuttings and insert the cuttings in a small pot filled with damp, peat-based potting mix. Enclose the pot and cuttings in a clear plastic tent to retain the moisture in the soil and around the leaves. Place the pot in bright but indirect light where it will not get overheated by direct sunlight. Keep it in a warm location (above 65 degrees F.). Allow 6 – 8 weeks for roots to develop, after which you can gradually remove the plastic over the course of a week. Increase the light after that. If you have more questions feel free to write again.. Good luck.
