For example, do not park the car in front of the plant for a long period. For fungal diseases, you can use fungicide or prune the plants to increase the air and light circulation as well as reduce fungus development. Here are two ways you can prepare a fungicide at home;.

Here are some tips;. So, before taking any action, always remove the yellow leaves first. Gardenias are acid-loving plants. They need acidic soil for uptaking the required nutrients. Generally, they grow well in soil pH between 5.

If the pH remains in the optimum range, then soil pH is not responsible for yellow leaves on gardenia. But if the pH of the soil is higher than 6. Also, you can also prepare a homemade solution to acidify the soil pH.

Here is the DIY procedure for you-. Note: Coffee grounds are highly acidic in nature. It helps the soil to reduce pH and also provide nitrogen to the plant. Lack of the required nutrients in the soil also can be the reason for yellow leaves on gardenias.

Lack of nitrogen, magnesium, iron, and manganese can turn the leaves yellow. But magnesium and iron deficiencies are the most common problems for yellowing leaves. Interveinal chlorosis is the identifying symptoms of magnesium deficiency. The lower or older leaves turn yellow first between the leaf veins and the tips of the leaves remain green. Note: Epsom salt is the natural source of magnesium. So, it can provide magnesium to your plant.

Then probably the leaves are yellowing for poor drainage. Generally, the drainage problem mostly occurs in potted plants rather than in-ground gardenia.

As a result, the leaves of the plant are getting yellow. Complicating the issue is the fact that you cannot automatically attribute the yellowing to just one cause. Instead, you must work your way through a checklist of possible causes to find the answer. For any individual gardenia plagued with yellow leaves, you must eliminate all of the possible causes that don't fit until you arrive at the one that does.

Check for signs of disease such as the mold left by fungi and insect infestations first so that you can rule them out or treat them immediately if they are present. Once you've ruled out diseases and insects, explore the possibility that your gardenia suffers from chlorosis.

It can be satisfying to attach a name to a condition, but saying that a plant with yellow leaves has chlorosis really only just begins to tell the story. But, on a practical level, this still does not identify the cause. There can be more than one reason for such a deficiency. Moreover, there are different kinds of chlorosis each indicative of a different nutrient deficiency. Send a soil sample into your local county extension and have them test it for deficiencies. The extension may recommend a solution for you when they deliver the results of the test.

But don't assume you can simply fertilize to solve the problem. The issue may be that, although the required nutrients are present in the soil, the gardenia is unable to access them. This is why it's important to know what kind of soil pH your plant needs. In the case of acid-loving plants such as gardenias, if they are growing in a soil that's too alkaline, the nutrients they need even if present in the soil will be unavailable to them. To reduce soil pH and make it more acidic, you can use a fertilizer containing sulfur, for example.

The problem of nutrient unavailability can also occur if the plant in question has suffered root damage, which can happen if your gardenia roots are sitting in water. Roots need to breathe, and drowning them in water cuts off their air supply, resulting in damage. Thus the need to pay attention to two of the other growing needs for gardenias: a soil with good drainage and adequate but not excessive moisture.

These conditions are closely related since a soil with poor drainage is likely to be too wet even if you are not guilty of over-watering. If root damage has occurred, it may be too late to fix the problem and would be a lot of work : replace the gardenia.

Your goal in watering is to keep the soil evenly moist right through the root zone ; it should not be soggy. To prevent drainage problems, work a lot of organic matter into the soil.
