Honeysuckle Plant


Question
QUESTION: I have a new Honeysuckle Plant (about 6 wks. old) which was a gift from a friend as a memorial to my sister, so it's VERY special to me.  It's just coming into bloom, but the lower leaves are yellowing and have tiny black spots.  I don't see any insects.  It seems to be affecting the new buds, some of which are turning brown before opening.  Any ideas?

ANSWER: Hi

Rub the black spots with your fingernail and see if they come off.  If they do, this will be an insect.  If they do not come off, there could be a fungal or bacterial leaf spot.  Please respond back with your observations and I can provide a more definitive recommendation.  Thanks.

QUESTION: They don't rub off - my guess is a fungus... we've had lots of rain in the last couple of weeks.  Is there a way to tell the difference between a bacteria and a fungus?  This morning I pulled back all of the mulch hoping this will give the soil a chance to dry out, if it's a fungus.  By the way - I am grateful for your quick response.  Thank you!!!  Elaine

Answer
HI

It is difficult to tell the difference without a microscope.  I would go ahead and buy some Hi-Yield Copper Fungicide/Bactericide from  garden center.  Treat the plant according to label directions for ornamentals.  Take the plant into a protected environment if possible and do not water overhead.  Re-treat the plant in about 7-10 days and then watch for spots to develop on the new growth.  If you see this, re-treat again.  Good Luck.
