Magnolia in a vase

Question: my magnolia is suffering, why?

I have a potted magnolia, despite the continuous growth, the initially beautiful green leaves, slowly become brown, curl up and fall! ... almost all the leaves sn in this state. Do you have any idea what it could be?

Pot magnolia: Answer: pot magnolias

Dear Alberto,
it is not easy to understand what afflicts your magnolia, without seeing a photo, and without even knowing what magnolia it is. However, consider that all plants, even the evergreen ones, periodically lose part of the foliage; only when this event strips much of the branches, or when, as you say, the leaves appear crumpled and ruined, then it can be a disease or a parasite. The fact that your magnolia is in a pot, and therefore in "controlled" conditions, makes me think that it could be problems due to watering; potted plants are forced to develop a forcibly contained root system (due to the pot itself), and therefore tend to suffer more, compared to plants in the open ground, due to excess water or drought. So, if you don't already, remember to water your magnolia every time the soil is dry, wetting it well in depth and not only on the surface. If the pot is exposed to the elements, your watering operations will be only sporadic, to be provided only in the hottest and dryest periods of the year; if, on the other hand, the vase is positioned where it receives no more water than the one you supply, then, especially in spring and autumn, you will have to water regularly. In any case it prevents the soil from remaining wet for a long time, because the roots drowned in stagnant water often quickly develop mold and rot, which can ruin the whole plant.
Another problem that afflicts your magnolia could be the excess of insolation: the magnolias love to be exposed to direct sunlight, but during the very hot months they prefer to be slightly shaded, receiving the sun only during the coolest hours of the day. Otherwise, the hot summer sun will cook them. If you believe that the waterings have been supplied in the best way, and that the hours of direct sun are sufficient, and not excessive, then it could be a problem due to excessive fertilization; the fertilizer is a product to be used regularly with plants grown in pots, but avoiding excess; when we plant a new plant, with fresh soil, our shrub is already fertilized, because fertilizer is already present in the bags of the nursery soil; in the following months, usually a spoonful of slow-release granular fertilizer is sufficient, to be supplied about a couple of months after planting the plant; in these cases we also avoid excesses, because large amounts of mineral salts in a limited area can be very harmful to plants.
