It is during autumn that the citrus put their energy into fattening and plumping up these little green cannon balls of fruit and it is then the shorter cold days that brings on their vibrant colour.
At this time during autumn it is best to remain consistent, keep your watering even just a little feed of organic fertilizer – if you get too heavy handed with the food you may end up with growth in the foliage at the detriment to the fruit. Organic tonics are a very safe option at fruit development stage.
Please don’t panic if your citrus drops some of it’s developing fruit. It is impossible for them to carry all of the fruit and they often need to shed some fruit to save stressing themselves as a tree.
In very young trees we would even encourage you to sacrifice the fruit and let the plant put it’s energy into becoming a stronger larger tree that in future years, will hold massive crops. Patience always works best with citrus, they don’t like to be hurried.
