Jasmine Plant Leaf Problems: Why a Jasmine Has White Spots If your jasmine has white spots, it’s time to diagnose and treat the problem. White spots on jasmine leaves may not be serious, but they can also indicate a disease [1] or pests [2] . Read on for more information about jasmine plant leaf problems.
Common Jasmine Plant Leaf Problems
Many jasmine species [3] are hardy enough to resist most diseases. Jasmine also tends not to suffer damage from insect pests. However, some diseases and pests can affect any ornamental shrub, and jasmine species are not completely immune.
A fairly common problem that causes leaf problems on jasmine plants is called leaf spot [4] and is caused by fungi. Look for irregular brown or tan spots, round or oval, that appear on the leaves in July or August. Leaf spots are particularly common in cool weather with frequent light rains or high humidity.
It is not too serious if leaf spot forms a few white spots on jasmine leaves, but if defoliation occurs it is more serious. To prevent leaf spot from recurring the following year, fertilize the plant [5] appropriately in the spring and prune [6] to remove weak or dying branches. You should only use fungicidal sprays [7] if the jasmine’s life is in danger.
Whitening jasmine leaves can also be caused by other things.
If your jasmine has white spots on the leaves, take a closer look. If the spots look powdery, the white spots on jasmine leaves could be powdery mildew [8] or true mold. Control these conditions by using an appropriate fungicide spray and repeating every two weeks until you have applied three sprays.
White spots on jasmine leaves may be insects. If the white spots on jasmine leaves are actually eggs or very small moths, the culprit could be a type of whitefly. Whiteflies [9] are tiny insects that feed on the underside of jasmine leaves. They also lay their eggs on the underside of leaves. Treat your infected jasmine leaves with insecticidal soap or vegetable oil spray [10] . These remedies are not toxic to you or your pets, but they will get rid of whiteflies in a short time.
Growing Italian Jasmine: Tips For Caring For Italian Jasmine Bushes
Italian jasmine bushes ( Jasminum humile ) delight gardeners in USDA plant hardiness zones [1] 7 through 10 with their glossy green leaves, fragrant buttercup yellow flowers, and glossy black berries. They are also called Italian yellow jasmine bushes. When planted correctly, Italian yellow jasmine is an easy-care plant that requires little human intervention. Read on for information about Italian jasmine care and pruning.
Italian jasmine bushes
Italian jasmine bushes come from western China. They were introduced to this country for ornamental purposes. Many gardeners grow this shrub for its pretty Italian jasmine flowers, which attract bees [2] and hummingbirds [3] in the summer. These yellow flowers develop into black berries in the fall.
The flowers appear in waves in May and June. The Italian jasmine flower returns in smaller quantities in the summer, contrasting beautifully with the bright green leaves that remain on the bush all winter in mild climates.
These Italian yellow jasmine bushes grow quite quickly, especially if they are watered regularly in the summer. They reach their full height of 12 to 15 feet (3.6 to 4.5 m) in five to 10 years. The ‘Revolutum’ variety is a popular, fast-growing choice for flower borders and beds.
Cultivation of Italian jasmine
Growing Italian jasmine begins with planting the bushes in a good location. The ideal growing location for Italian jasmine bushes is a warm, sheltered area where the plants receive full sun [4] and enjoy well-drained soil. If you can give your plants these conditions, the Italian jasmine flower scent will be sweet and strong.
However, if the ideal is not possible, you can also try growing Italian jasmine in areas with only partial sun [5] . They can also tolerate cooler locations as long as they are planted in soil that drains well.
When you start growing Italian jasmine, you will notice that it is a delicate plant. Although it climbs like a vine up to 12 to 15 feet (3.6 to 4.5 m), it is best to treat it like a climbing rose [6] and tie its branches to a trellis as they develop.
On the other hand, you will not spend a lot of energy caring for the shrubs. Italian jasmine bushes are generally disease-free and require no pesticides or sprays for radiant health. However, you may need to start pruning Italian jasmines when they outgrow their allotted space.
These undemanding shrubs thrive in almost any type of soil, whether acidic, alkaline or neutral [7] . They can grow happily in clay, sand, chalk or loam as long as the soil drains well, [8] and make exceptional additions to the landscape.
Star Jasmine as a Ground Cover: Information About Star Jasmine Plants
Star jasmine (Trachelospermum jasminoides ), also called confederate jasmine, is a climbing plant that produces highly fragrant, white flowers that attract bees [1] . Native to China and Japan, it grows very well in California and the southern United States, where it provides excellent ground cover and climbing decoration. Read on to learn more about growing star jasmine in your garden.
Growing Star Jasmine Vine
Gardeners in warm climates (USDA zones 8-10 [2] ) can grow star jasmine as a ground cover where it will overwinter. This is ideal as star jasmine can be slow growing at first and may take some time to become established.
Once fully grown, it will reach a height and width of 3 to 6 feet (1-2 m). Prune any upwardly reaching shoots to maintain an even height. In addition to ground cover, star jasmine plants climb well and can be trained to grow on trellises, doors and posts to create beautiful, fragrant decorations.
In areas cooler than Zone 8, you should plant your star jasmine in a pot that can be brought inside during the colder months or treat it as an annual.
Once it gets going, it blooms most in the spring, with sporadic blooms throughout the summer. The flowers are pure white, pinwheel-shaped and beautifully scented.
How and when to plant star jasmine in the garden
Star jasmine care is very minimal. Star jasmine plants grow in a variety of soils, and although they bloom best in full sun, they do well in partial shade and can even tolerate heavy shade.
Space your star jasmine plants 5 feet apart if using them as ground cover. Star jasmine can be planted at any time, usually as cuttings propagated from another plant.
It is resistant to disease and pests, although you may see problems with Japanese beetles [3] , scale [4] and sooty mold [5] .
Yellowing Jasmine Leaves: Why Do Jasmine Leaves Yellow?
Jasmine [1] is a beautiful vine or shrub plant that shines in good, well-drained soil [2] and full sunlight [3] , but adapts happily to less than perfect conditions. Although the plant is easy to grow, pests or environmental issues can cause yellow leaves on jasmine plants. Read on to learn more about the causes of yellowing jasmine leaves and how to treat yellowing jasmine leaf.
Reasons for jasmine leaves turning yellow
Below are the most common problems to be aware of when a jasmine has yellow leaves.
Pests
Pests may be the culprits [4] if your jasmine has yellow leaves. Rule out a pest infestation before moving on to more complicated troubleshooting. If you discover an infestation, treat the pests with insecticidal soap or horticultural oil.
Scale: Scale [5] is a tiny, sap-sucking pest that attaches itself to jasmine stems and leaves. Tinder can be recognized by its protective coating, which, depending on the type of scale, can be a waxy substance or a hard shell.
Mealybugs: Mealybugs [6] are tiny pests that are easily identified by a whitish covering that can be mealy, waxy or cotton-like. Like scale, the beetle causes leaves to turn yellow by sucking the sap from the foliage. If the plant is small, use a toothpick to pick off the masses by hand.
Spider mites: Spider mites [7] are another sap-sucking pest. The tiny, pinpoint-like pests are difficult to spot with the naked eye, but you’ll likely notice the telltale webbing on the leaves. They are attracted to dry, dusty conditions, so be sure to water properly and keep the leaves clean.
environmental issues
Yellowing jasmine foliage can also result from problems in its growing environment, including cultural problems.
Nutrient Issues: Jasmine plants are susceptible to chlorosis [8] , a condition that occurs when the plant lacks nutrients – usually iron [9] . But a deficiency in zinc [10] and manganese [11] can also cause chlorosis, which, depending on the severity of the deficiency, begins with stunted growth and pale green or yellowing leaves. A foliar spray containing chelated nutrients may improve the condition, but probably only temporarily. A soil test [12] is the only sure way to identify soil deficiencies that may be responsible for yellow jasmine leaves.
Improper Watering: It may sound contradictory, but both too much and too little water can cause yellow leaves on jasmine plants. Jasmine grows best in rich, organic, well-drained soil. The soil should be moist, but slightly dry soil is preferably overly moist, waterlogged soil, which can not only cause yellow leaves but also kill the plant.
pH Issues: Yellowing jasmine foliage also occurs in poor soil conditions. Although jasmine is forgiving, it prefers acidic soil [13] . If your soil is highly alkaline, this imbalance can result in yellow leaves. An application of sulfur or the addition of woody organic matter can help balance pH, but be sure to have your soil tested before attempting to make corrections.
