Do you love jasmine? They are plants of exceptional beauty, very easy to care for, but there are some species that are more interesting than others, not because of their ornamental value but because of their rusticity. An example is the Jasminum nudiflorum, much loved for the amount of flowers that sprout in winter-spring, despite the cold that may be in the area.
The best thing is that it can be grown both in pots and in gardens, be they small, medium or large. So, without further ado, let's see what its maintenance is.
Origin and characteristics
Known as winter jasmine, San Jose jasmine or yellow jasmine, is a deciduous climbing shrub originally from China. It can reach a height of no more than 3 meters, with dark green pinnate leaves arranged in an opposite way.
It blooms in winter and until spring of the branches without leaves of the previous year. The flowers are small, 1-2cm in diameter, bright yellow in color, and although they emit a pleasant aroma, it is not as intense as that of other jasmine.
What are their cares?
If you want to have a copy, we recommend you take care of it in the following way:
Location
It is a plant that has to be outside, in full sun or in semi-shade. If you live in an area with very hot summers (with a maximum of more than 30ºC and a minimum of more than 20ºC), it will grow better protected from the sun.
Earth
It depends:
- Garden: it is not demanding, tolerating limestone without problems. But he does prefer it to be rich in humus, and with good drainage.
- Flower pot: fill with universal growing medium (for sale here) or with mulch (for sale here).
Irrigation
Irrigation frequency should be regular, avoiding extremes. It does not resist drought, but neither does waterlogging, so it is advisable to check the humidity of the soil. In this way, the roots will receive the water whenever they really need it.
And by the way, do not wet the leaves or flowers. In addition, it is important that when you water, you really water; that is to say, that you add as much water as necessary so that, if you have it in a pot, you will see that it comes out through the drainage holes; and on the other hand, if you have it on the ground, add a minimum of 7-10 liters.
Subscriber
Throughout the year, but especially in winter and spring, you can (and we advise you to) pay your Jasminum nudiflorum with Organic fertilizers, since this way you will have a healthy plant, which will grow with strength and vigor, and which will also produce a large number of flowers every year.
As such you can use compost, guano, or others that you will see in the link, but if you have it in a pot, use liquid fertilizers like this one that they sell here, following the indications specified on the package.
Multiplication
It multiplies by cuttings and suckers in spring. How to proceed in each case? We tell you:
Cuttings
You have to cut a branch of semi-hard wood that has leaves, impregnate the base with homemade rooting agents or rooting hormones (for sale here) and plant it in a pot with peat placed outside, protected from direct sun.
To avoid fungus, it does not hurt to sprinkle sulfur (on sale here) across the surface of the substrate.
Young
The suckers are shoots that come out of the root, on all sides of the plant. To separate them you have to make trenches about 20cm deep, and with the help of a serrated knife previously disinfected with alcohol, cut and remove them from the ground.
Then you will only have to plant them in individual pots or in other areas of the garden.
Pruning
Yellow jasmine is pruned after flowering, energetically, like rose bushes. Don't be afraid to trim its branches more than half; with that you will get him to get new ones that will be the ones that will flourish the following year.
Of course, use pruning tools disinfected before and after use, with pharmacy alcohol or a few drops of dishwasher. Failure to do so would run the risk of infection with fungi, bacteria and / or viruses.
Pests
You may have the following:
- Borers: inside the trunk and branches the larvae of the Hylesinus excavate galleries, destroying the plant. It is treated with specific insecticides. More information.
- Mealybugs: be it the cottony one, the limpet type or others. You will see them in the leaves, especially in the tender ones. They are fought with an anti-mealybug insecticide or with diatomaceous earth (the dose of the latter is 35 grams per liter of water). More information.
- Cantharides: it is a beetle, lytta vesicatoria, which has an elongated, metallic green body that measures 1-2 centimeters. Jasmine leaves are sometimes eaten. It is not necessary to treat them in general, but if you see that there are many, apply diatomaceous earth.
- Weevils: they are like beetles of the genus Otiorrhynchus, dark in color and 5 to 12mm long. Treat with chlorinated insecticides, or diatomaceous earth.
- Jasmine Piral: the caterpillars of the Margaronia or Glyphodes unionalis moths feed on the young leaves. They are treated with insecticides based on sulfur or copper.
- Trunk drill: butterfly caterpillars Zeuzera Pyrina they open galleries in the trunk of 1cm in diameter. They are yellow in color, and grow up to 6cm when they finish growing.
Management
You may have the following:
- Mildew: it mainly affects the youngest leaves, which are covered with brown spots and dry out. It is treated with fungicides. More information.
- Root rot: it can happen if the ground is very humid or very fertile. Control the risks and, in a preventive way, it can be treated with ecological fungicides once a month.
- Tuberculosis: the branches appear warts or tumors produced by the bacteria Pseudomonas savastanoi. It is very contagious (between plants), so all affected parts must be cut and burned.
Planting or transplanting time
El Jasminum nudiflorum planted in autumn if the weather is mild, or late winter. If you have it in a pot, you should transplant it to a larger one every two or three years.
Rusticity
It resists frosts of up to -17ºC, but in hot climates it does not grow quite well, since it needs to be cold for a few weeks to be able to flower.
