Rosa Margaret Merril ('Harkuly')
rose Margaret Merril (floribunda)
- available to order from spring 2021
- 3 litre pot
This rose is deciduous so it will lose all its leaves in autumn, then fresh new foliage appears again each spring.
- Position: full sun
- Soil: fertile, humus-rich, moist, well-drained soil
- Rate of growth: fast-growing
- Flowering period: July to September
- Hardiness: fully hardy
Delicate, double, exceptionally fragrant, pale pink to white flowers from July to September and crisp, dark green leaves. This vigorous, cluster-flowered bush rose is perfect for an open, sunny site with fertile, moist, well-drained soil. Offering good resistance to disease, the beautiful high-centred to cup-shaped blooms make excellent cut flowers.
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.
- 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 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.
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 on hybrid teas, 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.
