Leaves with dry or dark tips: Let's talk about some plant diseases that cause dry, brown tips. Here's what to do if the leaves are yellow, spotted brown, or have dry tips.

Leaves with dry tips

Thecausesmore common can be related to water stress. If you are in the middle of summer and you do not water your plant in a wayconstantIt is possible that the first symptom you notice of this water stress is the dry tips of the leaves. This condition occurs when the plant is exposed in a very hot place, with a torrid climate or if placed in a sunny place. Water stress is induced by non-constant irrigations: for example, abundant irrigations but performed at irregular time intervals. To overcome this problem, which is generally typical of plants grown outdoors in summer or near heaters in winter, you can simply correct the frequency of irrigation.

If you are in the height of summer, try watering the plants by immersion, that is, immerse the pot in a container of water and let the water reach and cover 1/3 of the pot. This irrigation technique is also very useful for bonsai with dry leaf tips.

Brown or black leaf tips

Again it is water stress. The tips of the leaves appearwitheredfor a few millimeters or, in severe cases, even for a couple of centimeters until it appears dry and crumpled. The brown color affects the apex of the leaf and the outermost margins adjacent to the tip.

Also in this context, theplant suffers from dehydration: dry air, high ambient temperature or sun exposure can cause this dryness located only at the apex of the leaf.

In addition to adjusting the flow of irrigation, if the environment is too dry, you will need to adjust the amount of humidity in the air. Like? Put expanded clay in the saucer and make sure that the clay grains are always moist, or, on a daily basis, mist the leaves with distilled water, perhaps recovered from the conditioner.

If you haven't spotted watering defects, check the drain hole - if you see the roots, it's time to repot. If the plant has little soil available, it will not be able to absorb the amount of water necessary to support its water needs.

Theplantswhich can undergo water stress and showblack, brown, dry or crumpled leaf tipsthey are generally those that have a greater water requirement or that are in full vegetation.

Among the various plants I point out theash bonsaiand any bonsai, both evergreen and deciduous, ornamental plants with elongated leaves (Kentia, Areca, Chamaedorea, Chlorophytum, Dizygotheca, Beaucarnea and Cyperus). Also very at risk are all the plants that should be kept in partial shade or in areas sheltered from the sun but which due to inexperience are kept in full sun, among these are all ferns, maranta, aglaonema, croton (codiaeum) ... Even citrus fruits (lemon, orange, mandarin ...) are not immune to water stress, especially if grown in pots.

In these contexts, the plants have dry spikes due to exposure or irrigation errors, however in other cases it could be a fungal disease and treatment is required.

Plants with yellow leaves

Irrigation errors can also cause leaf yellowing, especially if tap water is used, however yellow leaves can be indicators of nutritional deficiencies or disease. If your plant has yellow leaf tips, it is probably due to water stress but to avoid the presence of nutritional deficiencies, I invite you to read the article: Plants with yellow leaves, because the leaves of the plants turn yellow.

Leaves with brown spots and dry tips

To the untrained eye, some fungal diseases can be confused with water stress but it's easy to tell the difference. If the leaf, over show a dry point also shows other spots along the lamina, surely it will be a disease.

If the leaves have yellow brown or brown spots or patches, they initially appear as dotsbut as they grow larger, it is likely that a cryptogamic disease is in progress.

This problem is caused by various fungi but a generic copper-based fungicide can be used for treatment. The Bordeaux mixture is a good ally even just as a precaution.

If you have corrected any irrigation errors, it is right to do a cupric treatment just to prevent diseases. When the plant is weaker (dry tips are a sign of distress) it is more exposed to fungal diseases or pest attacks. It would be advisable to intervene to protect the plant from further damage.

The Bordeaux mixture is easy to use: just dissolve 25 grams in 2.5 liters of water. This quantity will suffice for 2 medium-sized plants. If you intend to do a broad spectrum treatment (for example, to treat all the plants in the garden, you can dissolve 100 grams in 10 liters of water).

The Bordeaux mixture is easy to find, you can contact any agricultural consortium or on Amazon, where a half kg bag can be bought at a price of 11.30 euros with free shipping. For all information on the product mentioned, I refer you to the Amazon page: Bordeaux mixture.

What to do?

Apart from the fungicide treatment, you will have to move the plant and place it in a well-ventilated place. Eliminate all leaves affected by the disease, even if this means eliminating much of the aerial vegetation. Fungal diseases spread easily and quickly, it is better to keep the plant on the sidelines until you are able to eradicate the attack. Perform only the essential irrigations and avoid wetting the leaves.
