I'm getting a lot of lower leaf drop on my coleus, which is outside. When it was inside and happening, I assumed it was due to not enough light. Now I"m getting it on some of the plants outside. Does anyone know what causes this? They are not suffering from lack of water.
I think I might have both of those. I started another 50 cuttings today.
I get leaf drop when the lower leaves get no light.
They also may be over watered. Just what that means here. Add a dab of Hydrogen Peroxide to your water. I foliar feed with a mist.
I also check the main stalk. If it's getting woody I take cuttings and toss the stalk.
