My Tulasi plant (basil) leaves are turning black, collapsing into themselves (like folding into a small bulb shape very close to steam) and then dying. In the row, there are 7 plants with gaps, in random positions, 5 of them died/dyeing like this and 2 are only fine and green.

Ground water is used from many years only, no change in water source.

Please advice, below are the pics. enter image description here enter image description here enter image description here enter image description here

  • That does not look the herb basil that I know. That plant has square stems. Are you sure this is basil? – kevinsky Mar 31 at 22:17
  • Hi @kevinsky - there are 5-6 variations of Tulasi plants, we have 3 varieties in that row. These are Tulasi only. – surpavan Apr 1 at 6:35
  • Ocimum tenuiflorum (synonym Ocimum sanctum), commonly known as holy basil, tulasi (sometimes spelled thulasi) or tulsi, is an aromatic perennial plant in the family Lamiaceae from Wikipedia – kevinsky Apr 1 at 10:28

I suspect bacterial infection. The very first thing you must do is move the diseased plants away from all your plants, and at a minimum the two Tulsi plants that are still healthy. If they came from the same lot, you will be lucky if they survive.

If you used the same soil, or if they all germinated from the same set of seeds, you should also separate the two healthy Tulsi plants from the rest of your other plants.

Discard the 5 and do not reuse the soil or pots without sterilization. Do not throw in a compost pile either.

If you tell us more about how or where they were purchased/germinated, we may be able to help better. Can you try to get us clearer close-ups of the leaves, if possible?

  • any way to add medicals /chemicals to the soil and regrow them? – surpavan Apr 2 at 5:43
