- Mix in at least one bucket of rotted organic matter per square metre, ideally farmyard manure, in the area where roses are to be planted
- For a single rose plant, dig a hole roughly twice the width of the plant’s roots and the depth of a spade’s blade
- Apply general fertiliser, at 100g per sq m (3oz per sq yd) over the surface and fork it in
- Carefully tease out the roots of container plants as, if this is not done, the roots may be very slow to extend outwards, leaving the young plant more susceptible to drought in summer
- Place the rose in the centre of the hole and, using a small cane to identify the top of the planting hole, ensure the graft union (i.e. where the cultivar joins the rootstock and the point from which the branches originate) is at soil level (not below as this is reported to increase the risk of rose dieback)
- Back-fill gently with the excavated soil
- Spacing depends on type and habit.
If you are replacing roses with new roses, ensure that you dig out the soil to a depth and width of 45cm (18in) and exchange it with soil from a different part of the garden, as roses are at risk fromreplant disease, also known as soil sickness.
