With the end of summer we see how the days are getting shorter and the temperature is decreasing. The trees are beginning to prepare for the cold of winter , and this can be seen in the fact that the deciduous ones are dressed in their best red, yellow or orange autumn outfits, the evergreen ones are slowing down the rate of growth, and the fruits finish ripening.
The care that our bonsai needs from now until spring comes are many and varied.
Pass
From September (in the northern hemisphere) to November, it is recommended to fertilize with a fertilizer that has more phosphorus and potassium than nitrogen. This will help it better overcome winter weather conditions, and in spring it will sprout without any problem.
Also, and if you do not want to use chemical products, you can use organic fertilizers in small quantities.
Irrigation
With the arrival of the cold also comes the risk of frost, so it is highly advisable to water it in the morning to prevent the water from freezing. If it is somewhat chilly species, it will be watered with warm water.
Works with bonsai
Autumn is an ideal time to enjoy bonsai, since it is when you must prune, wire, transplant (especially evergreen species)… in short, do all the work that fans of this art love so much. It is also time to apply what is known as winter oil, in order to eliminate possible eggs that are deposited on the tree.
Our bonsai in winter should only be watered.
If you have a tropical species and you live in a climate with cold winters, it is advisable to protect it from those climatic conditions by making it a greenhouse or keeping it indoors with lots of light and away from drafts.
For the rest, it only remains to enjoy your work.
