There is also a lot of adventurous back budding. This new growth is very fragile and cant be touched. If you blow hard on it the new twigs will come off. I lost a few which were in perfect positions. Luckily i got more coming in the same place.
I am concerned about the color of the new growth. the chlorosis is really bad. Its getting fed once a week. Ive increased to twice a week, with chempak high nitro and growth technology citrus focus - both mixed over strong. The citrus focus has got seaweed and humates. I'm hoping this will improve the roots and soil. Ive also put some Mycorrhiza in the soil to improve nutrient uptake.
Last year i fed it like a madman to green it up - so i suppose as a larger plant it needs more. The citrus trees are notoriously greedy. I'm having doubts about the substrate I'm using. it did very well in akadama for the last 2 years. This biozorb doesn't seem to hold much liquid. in the small pot i could get a litre of water in without much runoff. This much larger pot saturates with 500ml so its capacity to hold nutrients is much less.
Once a week i take it onto the lawn and give it a good soaking to flush all the soil.
