Rosa Admiral (‘Tan08996’) (PBR)

A repeat flowering bush rose with dark flower buds opening to deep, luxuriant ruby-red double flowers that darken to purplish velvet. Disease resistant and strong-growing with a heady fragrance, reminiscent of ‘pear-drops’, ‘Admiral’ is a great choice for cottage gardens, beds and borders, or as a specimen for a suitably large pot where it will repeat flower throughout the summer.

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 be 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.

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 manufacturer’s 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.

In late winter, pop on a pair of tough gloves and remove dead, damaged, diseased or congested branches completely. Then cut back vigorous new shoots by up to a third, and shorten strong side shoots to within two or three buds of the main stems. If the centre of the shrub is becoming congested, remove one or two of the older stems to their base. After the first flush of flowers has faded, prompt deadheading will encourage more flowers to form.
