Your citrus plants should be fertilized regularly to avoid a lack of nutrients. You need a lot of iron and calcium.
Citrus plants need fertiliser
Perhaps you are one of those gardeners who would like to do without fertilizer as far as possible. If this is the case, then you should also buy easy-care plants, because many need a sufficient portion of nutrients, which unfortunately they cannot get from the mere administration of water. This also includes the citrus plants.
Citrus plants are not easy to care for
Citrus plants enrich every conservatory, are pretty to look at and delight every gardener with their tasty fruits such as limes, lemons or oranges. But they are not exactly easy to care for - they need sufficient fertilizer. Ideally, they are stored at temperatures below 15 degrees. The warmer they are, the more nutrients they need. You should also water your citrus plants regularly.
Fertilize citrus plants
Above all, citrus plants have a high requirement for calcium and iron. Although the calcium requirement is covered by the addition of calcareous water, the iron requirement is not. Therefore, the addition of fertilizers is essential. You can tell very quickly when the citrus plants have a nutrient deficiency. The evergreen plants then develop yellow leaves very quickly, which they then throw off. You should act now at the latest.
