Rosa Madame Hardy | Shrub Rose

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 plant's 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 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. As most shrub roses tend to flower best on older stems, they only need a little light formative pruning. Hard pruning should be avoided unless absolutely necessary as it can often ruin the plant's shape. The best time to prune is in late summer after they have finished flowering. While wearing tough gloves, remove dead, damaged, diseased or congested branches completely. If the centre of the shrub is becoming congested, remove one or two of the older stems to their base. If they have become too leggy, then you can often encourage new growth to form by cutting one or two stems back to within 10-15cm above ground level.
