Yellowing of the leaves in plants, trees and shrubs in the garden can be caused by several factors: excess watering, deficiency, inadequate sunshine, temperature differences, or even a draft. The symptoms are easily identifiable: part of the leaves are affected by yellow spots which spread rapidly and more or less uniformly, then fall, and growth is slowed down.

Problem n°1: Deficiency (or Chlorosis)!

It may be a deficiency issue. A deficiency frequently causes yellowing of the foliage. This is especially true for potted plants, which are more exposed to soil depletion. It can be an iron deficiency: we then speak of chlorosis. The yellowing, induced by the disappearance of chlorophyll, begins at the edge of the leaves and extends towards the veins, which remain green. All plant species can be affected.

Problem #2: Improper watering!

It could also be poor watering. Overwatering is a common cause of yellowing, especially for potted plants. A substrate that is too wet induces asphyxiation of the roots, which is irremediable: the plant can no longer feed properly, its leaves turn yellow, then it dies. Always wait until the substrate is dry on the surface before watering. Do not leave stagnant water in the saucers: most plants do not like to have their feet in water! A lack of water can also cause leaves to yellow, usually accompanied by rapid wilting: the effects of water stress are usually quite dramatic and difficult to confuse with signs of a deficiency.

Problem n°3: Inappropriate exposure!

Most plants do not like drafts or strong temperature variations. So make sure that your potted plants are not subject to this. Sunshine is also important: a plant in partial shade exposed to direct sun can show signs of yellowing. Conversely, plants that love the sun will not like a shady position. Do not worry too much if only a few leaves are yellow, especially if they are old leaves: even for evergreen plants, the leaves are constantly being renewed, so it is normal for the older ones to turn yellow.
