If the plant has only looked sad for the last month and not before I suspect it is just getting ready for autumn leaf fall. A lot of people worry un-necessarily at this time of year about poorly looking or diseased leaves on all manner of deciduous plants. Your leycesteria will lose most if not all its leaves in the coming months and what it is doing is absorbing back into the rest of the plant any goodness in the leaf before this happens. Leycesteria can be hard pruned I would suggest lightly cutting back the long growths now and if required pruning further in spring. But dont forget if it is in berry the birds will feed on these. If the problem has been going on longer or returns in the spring let me know, but I suspect all will be forgotten about. Best Wishes Andrew Pantiles Nurseries.
