Orchid with yellowing leaves: what are the causes?
Orchid with yellow leaves and wilted flowers? It often happens that the immune system of this ornamental plant weakens. The leaves turn yellow and the flowers fade. Yellowing of orchid leaves is caused by stagnation of water caused by too frequent watering. Direct and too intense sunlight, lack of fertilizers, mechanical damage and pests are also causes of weakening of the orchid. Orchids undergo a process of weakening and aging, during which the leaves turn yellow and dry.
Water stagnation between the leaves leads to the proliferation of fungal spores, bacteria and pathogens that attack the orchid stem causing blossom end rot. Another reason why the orchid may have yellow leaves is the use of an old and degraded substrate. Another problem that weakens the orchid is too much light.
Weakened orchid: add a teaspoon of this ingredient
There is an ingredient that is easily found in the kitchen cupboard and can be used to strengthen the immune system of the perennial plant. We are talking about glucose, which can be diluted in water and can be used as a fertilizer to feed orchids.
The same roots of the plant are predisposed to absorb sugary substances, but it should not be exceeded too much because the function is to reverse the osmotic process and cause dehydration of the plant.
Therefore, it is good to add a little glucose to the soil, but it is good to be careful not to exceed it because it could promote the proliferation of bacteria and fungal spores.
This should be done on a monthly basis. Many nurserymen recommend adding a little milk, which can also be used to clean the leaves, make them shiny and remove dust on the leaves and flowers of the plant. Expired milk can have a second life and can be used as a natural fertilizer.
