Honeysuckle Periclymenum Rhubarb & Custard

Hi there,

I would very much appreciate some good advice please. Firstly I have recently bought the above plant in a 2 litre pot. It is about 2ft high and I have recently moved to a flat where I now have a small balcony.  I know this type of honeysuckle is quite compact which is why I went for this one, but the wall of the balcony is only about 2ft so firstly, I would like to know whether to use the trellis I purchased although How would I make it higher than the wall? Does anybody know of any other mesh/climbing trellis I should use.  I do not have an obelisque and haven't got the space or money so I would appreciate any comments on this please.  Also, more importantly, some of the leaves have a white powder on them and at the bottom they have blackish spots yet at the very top the new growth looks healthy. I have had it a few days and need to plant it asap, also - what size (roughly) pot would be best recommended.  I await any useful comments in anticipation and they would be so very much appreciated.

Kind regards

    A 50cm pot would be the best size but you would need some sort of support unless you could grow it horizontally along your balcony.

  • Thanks for your response Ladybird4. Do you mean 50cm diameter or depth? I assume diameter?

    Sorry, yes diameter although depth should also be on the generous size too.

    It sounds to me as if your plant has powdery mildew. This often happens when honeysuckle suffers from drought. They need a cool deep root-run, damp soil and ' their feet in the shade and their faces in the sun'.  Get that right and your plant will be stronger and healthier. 

    That being said, honeysuckles often get a bit of powdery mildew at this time of year. My substantial honeysuckles planted in the soil  on shady banks against cool fences have got a bit of it in this dry spell and I've been using a seep hose to water them at the roots
