Unfortunately my absence has spent winter in a very hot place receiving little water and light, with loss of leaves and excessive stretching. Now he's back home what can I do for recovery? Repotting pruning fertilize help !!! Thanks x any help
unfortunately, it often happens that some plants are grown in an unsuitable climate, especially when it comes to bonsai, which many people consider too delicate, and therefore kept in the apartment even when it comes to outdoor plants. Now that your plant has received an unsuitable climate it will manifest typical problems: the fall of the leaves is often due to the excessively dry climate present in the house, or often also in the greenhouse, especially if heated; the excessive elongation of the branches is called etiolation, and consists in the elongation of the space between two internodes, due to a strong and persistent lack of light. So your plant was not only kept warm, but also in the dark and with little environmental humidity. The first thing you can do, to run for cover, is to keep the plant in a cooler and wetter climate, spraying it often with demineralized water, or placing the vase in a large pot holder, with gravel, and with at least a couple of centimeters of water, which will evaporate increasing the humidity of the air (the vase will not have to touch the water, and the gravel will have to keep it raised, to avoid having a soil that is always too wet). In addition to this, it would be appropriate to bring the plant back to the right brightness, or rather an olive tree at a few hours of direct sunlight; only that, if your olive tree has been in a too dark place for some months, you cannot move it directly to full sun, it would be advisable to do it gradually, so that it is not subjected to sunburn; even moving it outdoors is only possible gradually, especially if the plant has remained in a very hot place, like at home; in the sense: you cannot move a plant at 10 ° C which until yesterday was at a constant 20 ° C. If instead it was in a cold greenhouse, you can immediately move it outdoors, where it will enjoy a naturally cooler climate and a more humid air. As for the branches that are too long, potali them as soon as possible: consider that most of the care given to a bonsai is made to reduce the space between the internodes; if your olive tree has produced very long and thin branches, it has "spun" as they say in jargon, basically years of remodeling as bonsai may have gone up in smoke, and it will be necessary to repot it at least two or three times before things get back to previous state. Another tip, before leaving the plants to someone, it is advisable to explain very well how they should be kept; also because now you are back in possession of your plants, you must thank those who have kept them for you all winter, you cannot insult those who have done you a favor because you did it in a way that is not appropriate.
