Oranges originally come from the always wet monsoon regions of Asia, which is why not only consistent water, but also a regular supply of nutrients is immensely important. Otherwise, deficiency symptoms such as B. leaves turning yellow or completely falling off.
Fertilize potted oranges once a week
Start with the regular fertilizer application at the beginning of the growing season, i. H. from mid to late March. Start slow and increase the gifts. The nutrient supply should take place no later than September. During the winter break, however, the orange tree should not be fertilized at all, but only watered from time to time.
Why shouldn't I fertilize before the winter break?
Fertilizer should never be applied towards autumn, and watering can also be reduced somewhat. In this way, the plants are slowly prepared for the vegetation break and are not stimulated to shoot again by a possibly mild autumn. Juicy new shoots that only formed in September do not lignify sufficiently before winter and simply cost the plant too much energy.
Fertilize orange trees - how and with what?
If possible, use a liquid fertilizer that you apply once or twice a week with the irrigation water. Alternatively, you can also use a long-term fertilizer that releases its nutrients depending on the temperature or humidity. A complete fertilizer with trace elements that is effective for five to six months is recommended here. This fertilizer is easily incorporated into the soil surface.
Pay attention to the correct mixing ratio
There are numerous special fertilizers for citrus plants, but it all depends on the content. Therefore, a normal commercial fertilizer can also meet the special requirements of an orange tree; provided it has the correct mixing ratio:
- Complete fertilizer should have a mixing ratio of nitrogen / phosphorus / potassium in the
have a ratio of approx. 3:1:2 - A nitrogen deficiency is quickly revealed by the fading leaf color.
- Slow-release fertilizer should be in the ratio of 15% nitrogen, 5% phosphorus and 10% potassium
be mixed - For every 10 liters of soil, work a handful (approx. 50 grams) of slow-release fertilizer into the substrate

Orange trees should be fertilized at the latest when the dark green of the leaves slowly begins to turn lighter.
