    Hello, you can deter them with neem oil, as long as you don't spray in bright light. This can burn the tree. There are many more ways to control them, as well. Here is a collection of articles that can help: https://www.gardeningknowhow.com/special/organic/

    This depends on the age, and stage of the trees life. Generally, when the tree is less than 5 years old, the fertilizer will be high nitrogen. As the tree ages, the ratio of NPK will change throughout the season. Potassium and phosphorus are used most during fruiting and flowering. Usually, if you use a citrus fertilizer, they will be blended to suit most any citrus tree at most any time.

    How often do you fertilize? You will need to do this at least once per year. I recommend at least twice for container, but it is not completely necessary. This is usually due to a lack of potassium and phosphorus in the soil. It is also best to apply dolomitic lime and iron sulfate to the soil when you fertilize. This will save you much trouble in the long run.

    This will be due to lack of light. Even with a South facing window, there will not be near enough light. My citrus are, strictly, indoors so they are under artificial lighting.

    Generally, I recommend at least 200 watts of quality horticultural lighting per tree. They are very light starving and will not bear fruit without enough of it.

    There are many different types of lighting available. Should you choose HID bulbs, they will require ventilation and quite a bit of air movement. GOOD QUALITY LED will not need near the ventilation and will not need to be changed yearly, as with HID bulbs, but they are very pricey.

    KIND LED is my choice, since the larger fixtures are completely programmable, but they are not budget friendly. It is best to do research into the LED company before purchasing if you decide this way. LEDs get a bad reputation from cheap companies.

    "Severely" is the key term. Now you know why it is not advised.

    Best management practices for tree and shrub pruning is for minimal to moderate pruning only, light thinning and shaping and don't remove more than 25% of the foliage in a one year period. If you need more crown reduction, do it in stages over a couple or three years.

    You will just have to give it some time. The rampant re-growth that is a response to the severe pruning, will slow down in time. A 4 digit postal zone, is that Australia? Fall weather coming up should see a reduced growth rate. At which time you can thin and shape the new growth somewhat, but not to heavily. Spring should see a more moderate growth rate and some flowering.

    Do not fertilize with a high Nitrogen chemical fertilizer or you will stimulate more rampant growth. Use a complete organic fertilizer with adequate Phosphorus and Potassium that support flowering and fruiting.

    The second year will be most likely to get back to balanced growth and adequate fruiting.
