Around early summer, your plants should start to produce flowers, which can be further encouraged with a high-potash fertiliser once a week to replace the nitrogen feed. A fertiliser that's high in potash would be a tomato feed or a comfrey fertiliser. Depending on the variety, the ultimate height of your plant should be achieved before too many flowers are produced.

The rugby legend opens up about his Chelsea Flower Show garden inspired by living with HIV, and finding sanctuary in natureWhere do you live? My husband Stephen and I moved into our current house at the end of last summer. We had been living right on the Welsh coast but, as idyllic as it was, it also came with a lot of problems - including the noise and smoke from beach parties and bonfires. So, we decided to move to the country, just outside Bridgend, which is where I'm from.

Dear Tom,I have a hybrid rhododendron in a pot. It has been growing in the pot for three to four years, but unfortunately it now appears to be dying. The leaves are looking pale and are starting to curl up and fall off, and the new buds are dry. What can I do to revive it? Dear Nalin,Rhododendrons have a very shallow, dinner plate-like root system.

When to mulchThere are two schools of thought when it comes to mulching; those who like to mulch in the autumn and those who prefer to mulch in the spring. The rationale behind mulching in the autumn is that it protects the soil from the winter wet, locks in some of that summer warmth and maintains a slightly warmer temperature in the soil for longer, extending the season in which roots grow and plants establish.

Watering should increase as the fruit begins to set. There are no hard and fast rules for watering, because small plants in low temperatures and dull light conditions require very little, but more frequent watering is needed when temperatures are high, and the sun is shining, and the fruit is swelling. If in doubt, water a little less and more frequently, as overwatering will cause rot and the leaching of nutrients from the compost.
