My spring planted honeysuckle developed pale patches on some leaves (mostly near the fence) and I gave it a slow release fertiliser (Q4) assuming it was a deficiency.  I think it might now have powdery mildew.

Do I treat it for mildew and hope for the best or does it need more drastic treatment?  Also, I have some sunflowers planted right by it that have done well but also have pale edges to their leaves, is this normal and was it a bad idea to put sunflowers near the honeysuckle?

Looks like powdery mildew, which is caused by dryness at the roots. If it is newly planted then it probably needs a good watering. Amazing how long it can take for a plant to send out rooys from the original compost and of course the top growth stops rain from getting to the roots.

Cannot help with the Sunflowers, never bothered growing them.

Hiya lunar jim

It sounds like your soil is dry there.  Honeysuckles need some moisture.  The mildew is prob the result of being too dry.  Feeding wouldnt help either.  Planting sunflowers nearby would not have caused this but I bet your sunflowers are happy in that dry spot...?  If this was early in the season I would have said cut it back and water well but   I think just plenty of water is best course of action so late in the season

Great minds berghill....!

Can't answer your Q but my honey suckle doesn't do well where ever it's planted. I get black spots on mine, yellowing of leaves and poor flowering. In fact a rambling rose and clemantis has black spots too, both planted close by  unless there's a cure mine's heading for the compost bin and garden in the sky...

I have watered it every day when there has been no rain but the soil does look very dry quickly.  Do I spray it with the anti-fungus chemical now?

Sounds like they both need a good dose of Fungicide. Blackspot is something which attacks almost every plant in one form or another.

Water and food to get the plants healthy is also a good idea.

Water first and by that I mean drwon then if the problem persists, fungicide. Get the plant healthy first before using chemiclas.

Again, Berghill I totally agree.  A real good soaking. Then another. Create a reservoir ....mound soil around the root area to hold plenty of water.....and soak it.  If you can, say in a week, after a few soakings, mulch with some dried manure or compost.

Thanks, I'll water, mulch and wait.  That's great if it isn't about to keel over and die.  I've got a clematis armandii nearby that is mostly brown now, I don't think will last long and I don't want to be back to bear fence in a few weeks!

Thanks once again.

I'll give mine a good water too and a mulch.
