Dig it up, as it is in the wrong place :-( I have found that L. x tellmanniana and (to some extent) some others suffer badly from this if in too much shade. I have sprayed with toxic chemicals in some years and soft soap in others, and they are about as ineffective as each other. What honeysuckle is it, and is it in sun or shade?

interesting that Nick believes they suffer in too much shade as i remember reading recently they also suffer if they get full sun as they get crisped in the heat of summer. perhaps a happy medium is whats needed |

It is almost entirely nonsense when applied to the UK. Compared with even Mediterranean climates, the UK's peak sun strength and warmest days are weak and cool. Some plants adapted to northern Europe can suffer, but it doesn't really apply even to L. periclymenum, and ones that come from southern Europe, north America and Asia almost never do. There are few places there that have summers as cool as ours and sun as weak that do not have such cold winters that few woody plants thrive. L. x tellmanniana is a cross between a north American and an Asian honeysuckle, which could be why it can't take shade in our feeble summers. And, because I have done what is effectively a controlled experiment over many years, I am certain of my conclusions about its need for sun (at least in my garden). Regards, Nick Maclaren. |

My normal treatment of such things is to spray soft soap on the worst infections and leave the others to ladybirds etc. But this is Cambridge, where humidities are usually fairly low (by UK standards). If your honeysuckle isn't exposed to the rain, then honeydew will collect and get mildew. If THAT is the cause, the solution is to wash it off with plain water, perhaps with a bit of detergent or soft soap in. Regards, Nick Maclaren. |

Lonicera japonica is well known for doing this especially some forms, the only time its is truly happy is when it is growing in a swamp - then it can be too happy! The form Lonicera japonica 'Acumen' is the best for no leaf problems but does not have the best flowers, the best evergreen scented honeysuckle by a mile is Lonicera similis delavayi, that is however a bit tender. So try copious watering or better still dig it up! -- Charlie, gardening in Cornwall. http://www.roselandhouse.co.uk Holders of National Plant Collection of Clematis viticella (cvs) |
