My boy has gone to kinder to this morning and the sunshine was out in the garden. I spent an hour inspecting my plants.
A few of the older lower leaves of the kaffir lime is turning yellow as per above. I am puzzled why, not being sure if it is iron deficiency (as I do not know how to assess that) or if it is its reaction to the cold weather setting in. I read that iron deficiency shows first in young leaves and the veins remain green though the rest of the leaves yellow. But these leaves are older leaves. Moreover, I did feed the plant citrus fertilizer before and after potting on. Lime-induced chlorosis happens commonly in citrus. Even though there may be iron in the potting mix, it may be locked up by an excess of other elements (Antagonism). I needed to research more so that I will not lose this plant.
This is a young leaf of the calamondin plant and it does look a little like what's called iron deficiency - green vein, yellowing young leaves. I have bought a bottle of iron sulphate but has been hesitant to use till the customer service of Richgro replies me on whether is it a natural mineral or chemically synthesized. Peter Bennett's book talks about using alum to rectify the iron deficiency but gosh, I wonder where I can get that from.
The new chillies of the cayenne pepper seem to be shrivelling and dropping instead of developing. I wonder if it is the cold or if it is iron again. The whole plant does look a little lighter green compared to before. I think something seems lacking especially with putting on so many chillies recently!
The young leaves of the cayenne pepper yellowing and falling.
Some of the older leaves of the thyme are yellowing too but I have a feeling it is due to the cold.
It is happening to some leaves of the rosemary as well. More research to be done.
My curry plant has been pruned this morning. I read that curry plants do not take continuous rain well and can grow moldy or get pests due to the wetness. I remove as much leaves as I could to allow air flow between the stems.
The center of the plant is not congested now. I also placed the pot in the mini greenhouse so that it wont get rain this afternoon.
