Seeking all the experts out there.

Just while I was going out to water my basil plant just now, I realised that some leaves have developed dark spots as shown in the pictures. I have immediately trimmed the black leaves off, but does anyone know why that has happened and any possible solutions? I hope it doesn't develop to the rest of the plant...

This is my first basil plant, so please give any comments in case I am doing anything incorrectlyImage of basil leaf which turned black Image of basil plant with black leaves mostly trimmed off Thanks in advance. Ryan

  • Overwatering in combination with too little sun can cause basil plants to brown. Could this just be browning leaves rather than blackening? – Cavenfish Jan 21 at 7:02
  • Black leaves are how basil plants frown. Could be almost anything - cold injury if by chance the plant got exposed to ~ 36oF, or even stress from drying out briefly. Btw, your sweet plants would prefer to live in a bigger pot, ideally separately. Then they would have fuller crowns and grow more leaves for you to use. Also you can delay the plant putting most of its energy into seed production then dying back by removing the flower buds. Other than that it looks like you are providing for them beautifully. – InColorado Jan 28 at 19:31
