Kim Wilde answers your gardening questions.
I would like to plant one or two climbing roses, such as 'Paul's Himalayan Musk' or 'New Dawn'. Do I plant them now or in spring?
With its fragrant, silvery blush-pink flowers and glossy foliage, the repeat-flowering climbing rose R. 'New Dawn' is hard to beat. R. 'Paul's Himalayan Musk' is a rambler (flowering only once a year), again with blush-pink flowers and vigorous shoots. Roses are hungry plants, so add well-rotted organic matter (manure or compost), and mix in a handful of bonemeal when planting. Plant any time from winter to spring, avoiding frosty conditions.

The (pot) camellias on my patio have a prolific number of buds. Do I need to take precautions to ensure the blooms are not spoilt over winter?
As long as your container is in a sheltered spot in semi-shade, all should be well. Your London address means you are unlikely to suffer bad frosts, which can damage the flowers. Container plants are vulnerable to temperature change, so for a belt-and-braces approach you could wrap the container with horticultural fleece or bubble wrap. Mulching with bark, straw or grass clippings to a depth of 5cm (avoid touching the main stem) is a good idea. Make sure the soil doesn't dry out, but at the same time keep it on the dry side: too much moisture makes it prone to freezing.
I bought a Lonicera tragophylla some years ago. This year, it is down to a few dozen leaves and no flowers. It is in clay/flint soil. Any suggestions?
This honeysuckle thrives in shade, though it is not always easy to grow. All honeysuckles like moist, rich but light soil, so your clay/flint soil sounds like the culprit. I would try digging up the plant this winter, taking as much root as possible, then improving the soil condition by digging in plenty of well-rotted organic matter before replanting, ensuring that the soil never dries out. Alternatively, replace it with the common hedgerow species, L. periclymenum 'Graham Thomas'.
