Justifiably popular, ‘Iceberg’ goes on flowering right through the summer. Clusters of pink buds open to double, slightly fragrant white flowers, 7cm across. It is disease-resistant and easy to grow. There is also a climbing variety.
All our roses are grown in an open field and then dug up when the weather conditions are right in October or November. Some suppliers send out their roses as 'bare root' plants (ie without pots or compost), but we pot ours up as it helps to keep the roots hydrated and in good condition. As they are dormant throughout the winter, they will not produce any new roots until spring, so don't be surprised if the compost falls away from the roots when you take them out of their pots. The roses can be kept in their pots throughout the winter provided they are kept well fed and watered, however ideally they should planted out as soon as possible. They will already have been cut back so no further pruning will be required, apart from snipping off any tips that have died back. Routine pruning can begin in late winter the year after planting.
- Garden care: If planting in winter, choose a frost-free spell when the soil is not frozen. Roses are quite deep-rooted plants so dig a deep hole roughly twice as wide as the plants roots and mix in a generous amount of composted organic matter. A top-dressing of a general purpose fertiliser can be worked into the surrounding soil and we also recommend using Rose Rootgrow at this stage to encourage better root development. This is particularly important when planting into a bed where roses have previously been grown as Rose Rootgrow is said to combat rose sickness (aka. replant disease).
Remove the plants from their pots and gently spread out the roots before placing them in the centre of the hole. Try to ensure that the 'bud union' (the point where the cultivated rose has been grafted onto the rootstock, and from where the shoots emerge) is at soil level. You can judge this quite easily by laying something flat, like a spade handle or bamboo cane, across the top of the hole. When they are at the right height, back-fill the hole, firming the soil down gently before watering the plant well.
Water generously until well established, and apply a specialist rose fertiliser (following the manufacturers instructions) each spring. They will also benefit from a generous mulch of composted farmyard manure in spring, but make sure this is kept away from the stems.
While wearing tough gloves, prune in late winter or early spring, removing any dead, damaged or weak-looking stems completely. The younger stems tend to produce the best flowers, so if the plant is becoming congested, cut one or two of the older stems right back to their base, which will also help open up the centre of the plant. Then cut back the most vigorous stems to within 25-30cm from the base, and the thinner stems back a little harder.

Q:Which Roses will still be flowering in September?
I am getting married in September and want to give my parents a present to say thanks for all their help. I thought a rose bush would be a really good idea as it should last a long time and will remind them of the day. Ideally I would like to present it to them in flower on and would like it to have white flowers. Any suggestions?Asked on 7/4/2005 by Susan Genever
A:There are some lovely roses that should still be flowering in September - although ultimately this will largely be dependent on the weather. Below are the white ones we sell that would make a lovely gift, just click on the link below each plant name to find out more about that particular one.
