Yellow leaves due to excess moisture

Faced with a jasmine with yellow leaves and brown spots , it is most likely that we have a problem of excess humidity . These plants need frequent watering, but if we overdo it with water we will drown the roots, preventing them from absorbing nutrients and causing this effect on the jasmine leaves.

If you are watering your jasmine plant too often, space out the frequency of watering. Typically, a potted jasmine will have enough water with a watering every three days in warm months and a weekly watering in cold months. Always water the substrate without flooding and check before doing so that the top layer of it is dry.

It can also happen that the soil or jasmine pot does not offer adequate drainage and, although the frequency of irrigation is correct, the substrate retains too much moisture. A poor drainage is an almost guaranteed source of diseases jasmine , so it is very important that ubiques in an area of the garden where the water does not collect or that you prepare a light and substrate slightly sandy, in a pot with drainage holes. Coir is always a good option in these cases, as well as a river gravel bed.

Yellow leaves due to lack of nutrients

The other major cause of yellow leaves on jasmine is a lack of nutrients, probably nitrogen

Flowering plants need a large number of nutrients to flourish each year and if we do not provide them in the substrate or in the form of compost, they will not be able to develop well.

Make sure to properly fertilize your jasmine according to its needs, providing it with nitrogen or some organic organic fertilizer such as worm castings, which is always a great option.

In addition, jasmine is an acidophilic plant, which needs slightly acidic soils. If the soil pH is not adequate, the roots will not be able to absorb the nutrients from the soil even if they are there. Adding some sulfur to the substrate is one way to acidify it.
