20 days since hard prune in summer

My curry leaf #2 which I did hard prune to remove all the leaves as to the damage from sooty disease being so bad, now has 40 mm long new buds. This is 10 days after my previous update.

We had 18 consecutive days with sun shine less than 3 hours a day, which should be affecting growth of the curry plant. I am trying locate the pots where brighter to expose the plants to the sun.
