My snapdragons have brown spots on the underside and have yellowish leaves, No bugs seen. ?
Question:I used the miracle cure, and that did not help. Is it a bug or like a rust problem? Seems to drop flowers early also. Thank you.
Answers:
Sounds like a disease. Overwatering usually turns the whole leaf yellow without the spots. I would spray them with Bonide Remedy or Ortho Disease Control. Spray bottoms and tops and repeat as recommended. You should be able to get your plants back to a healthy state.
Over-watering could be a problem. This always leads to leaf turn yellow. Yes it could be bug / rust too
