Keep it well watered at the roots and mulch with some garden compost. It will be powdery Mildew causing the symptoms you describe, the only thing honeysuckle really suffer from. It will come back so don't worry.
I would say it isnt Powdery Mildew. You would have white patches on the leaves.
The chap at the garden centre was right in suggesting Rose Clear as your honeysuckle has black spot, a disease that usually affects Roses.
Most Honeysuckle are quite vigorous so this doesnt tend to trouble them too much.
I agree with Dave, honeysuckle leaves turn grey/black when succumbing to powdery mildew, before the fungus develops its powdery coat.
It affects honeysuckle that has been weakened by drought - honeysuckle, being a plant of damp woodlands likes it's feet to be cool and damp.
The leaves will go crispy and fall off but if you remedy the problem, plenty of watering (not soggy but moist) and shaded roots, the plant will recover.
No need to spray with anything. I believe Roseclear contains a fungicide so it will tackle mould-type problems, but the leaves that already have it will die, and if you cure the problem the new leaves won't get the mildew.
I bought a new honeysuckle this year and I think it had been a bit dry in the pot at the GC - a few weeks after planting it developed powdery mildew and all the leaves fell off, but it is planted in the right place, with shaded roots and moist but well-drained soil and it is recovering with new shoots appearing everywhere. The mildew only appears some time after the problem has occurred.
I do find that some garden centres like to solve your problems by selling you something!
Graham Thomas is a wonderful honeysuckle - I've grown one in a previous garden and it was one of the first plants I planted in this one. I find it takes a couple of years to get going, and then it's simply beautiful - such a good perfume and such elegant white and honeycoloured flowers - a very good choice
Hi, honeysuckle is pretty tough so hopefully yours will recover.
I'm planting another in a very dry area under some trees - when I plant it I'm going to insert a plastic bottle 'funnel' like this
to enable me to direct water straight to the roots of the honeysuckle - I use this method for growing courgettes in raised beds and it gets the water right down to the roots instead of running off the surface of dry ground.
I almost bury the bottle so that only a couple of inches is showing about the soil, so it's not too unsightly.
Just give it plenty of water to make sure the roots are damp and cool - it will recover
good tip Dovefromabove, will try that myself
Hi I bought a honeysuckle from my GC in June and have planted in a large garden tub attached to an archway (hoping that the honeysuckle would climb over the arch)...and at first it romped away but now for the last week I have noticed the leaves turning a dark colour and what looks like a light dusting of fungus on the leaves and the stems ...please help , what is the best thing to treat it with. I have kept it well watered and it gets sun until late afternoon.
It has Powdery mildew - keep the soil moist and the container shaded and cool - (if yuy can plant it in the ground that will be much better) - the leaves will go yellow and fall, but the plant will recover and grow again if you can get the cultural conditions right, see my posts above.
