Question: diseases of the pachira
Hi, I received a pachira as a gift that I initially exhibited on a covered terrace believing it to be sheltered but overlooks the street and in addition there was strong wind. after a few days I realized that many leaves had white and yellow spots and some holes. What can I do?
Sick Pachira: Answer: Pachira diseases
the pachira is a real tree in nature, widespread in South America; it has a very beautiful vegetation, with large palmate leaves; loves well-lit locations, but specimens that are grown indoors prefer not to receive excessive amounts of direct sunlight. So the location on your terrace, quite covered and semi-shaded, could be perfect. However, these plants do not like the stagnant air, and while they do not appreciate the cold air blows (for example in the apartment it is better not to expose them to the draft of the windows), they do not like the always still air, which quickly attracts a number of parasites. Typically, the pachiras grown in pots undergo heavy attacks by aphids and cochineal; both insects stick to the underside of the foliage, and suck the sap, causing light spots, and often the presence of fumaggini. In your case, the holes could instead be caused by a fungal-type pest, although not seeing a photo of the foliage makes it difficult to diagnose. In any case, the area you have chosen for the plant may not be completely incorrect, and probably the plant, for months in the apartment, is only a little weakened by the amble of position, and therefore more subject to attack by parasites. . If the leaves appear badly damaged, remove the most damaged ones. If you notice insects on the underside of the leaves, then proceed with a treatment with a systemic insecticide, which means that it enters the plant; for example, there are tablets to insert into the ground, which dissolve when you water. If you don't see insects of any kind, neither scale insects, nor aphids; but not even tiny insects, like mites, which produce thin cobwebs among the twigs; then proceed with a fungicide treatment, choosing a fungicide that can be sprayed directly on the foliage. Then try to cultivate the pachira as best as possible, so that it can recover from the stress of moving from home to the terrace; so water only when the soil is dry, provide good green plant fertilizer, and try to leave the plant in place with good air exchange.
