The Royal Horticultural Society bare root hedging range is a very low cost way of planting a hedge. The bare root plants are only available to buy and plant when dormant. (November-March) These plants, with known seed provenence, are grown in 220 acres of rich Herefordshire soil. As they are dispatched directly from the fields, rather than through a nursery, they are much fresher than imported or even stored plants. RHS bare root plants are grown through low input horticultural methods. Plants are rotated with pigs annually, to improve soil condition. Water is harvested in the winter for use in the summer. No heat or polytunnels are used and, as the plants are dispatched direct from the fields, transport is kept to a minimum.

Masses of fragrant, single, yellow-centred, white flowers from July to September, followed by large, red or orange-red rose-hips. This vigorous, white species rose makes a great, informal, flowering hedge for an open, sunny site. An excellent choice for the wildlife garden, the leathery, dark-green leaves turn butter-gold in autumn.
Please note that as we grow the hedging especially for you, we need to take full payment when you place your order so as to reserve stock for you. The bareroot plants will then be despatched to you during November.
All our roses are grown in an open field and then dug up when the weather conditions are right in October or November. 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.
These are sent out as bare root whips and should be planted out as soon as possible.
- 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.
As most shrub roses tend to flowers 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 plants 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.

Q:I planted my rugosa hedge last November. It has grown vigorously through the summer and the plants look very healthy and happy, but they have failed to flower, no buds developing at all. What am I doing wrong? I wanted a rugosa hedge for the lovely flowers and then large rosehips for autumn colour.Asked on 3/9/2015 by jennyanydots from Oxford
There are a number of reasons why plants don't flower including too much shade or not enough water or nutrients. It can also be caused by the plant putting on new root growth instead of focusing its energies on producing flowers. I am not really sure why yours has not produced buds, but given time and the right conditions, there is no reason why it won't flower. I would make sure that it is in full sun, and you can often give them a bit of a push by feeding during the growing season with a high potash fertiliser.

Q:I want to place some rosehips in my hedging scheme, mainly for the flowers and hips in the autumn, but I do not want it to grow to 2m - does this mean it is a bad choice as I will be forver chopping of the fruitful growth?Asked on 17/4/2014 by more garden than I can handle from Surrey
This rose is lovely for an informal hedge, which can grow to 2.5m eventually. If you are looking for a more formal clipped hedge then this plant might not be the one for you.
Most shrub roses tend to flowers best on older stems so really you need to prune it after it has finished flowering in the autumn. Hope this helpsAnswered on 22/4/2014 by Anonymous from crocus
Q:Hi, I would like to plant a rosa rugosa alba hedge. How far apart should I space the plants? What compost should I use? Thank you!Asked on 12/11/2013 by Rose from Oxfordshire
I would plant them about 45cm apart, and I would mix a well rotted organic matter like our Levingtons organic farmyard manure in with the soil.

Q:Hi, I'm having trouble with rabbits coming into the lower part of my garden and eating all the flowers, so I would like to plant a low-growing hedge, which can be pruned so it won't get at all leggy, along the edge of the lawn (and will insert a gate/barrier across the steps at night) to completely block their way. I had been wondering about a rugosa hedge but I want something that will only be about 50-60cm (2'max) high and quite neat, so as not to totally block the view of the lawned part of the garden from the house. I don't really want box as I'm planting that elsewhere, and thought something prickly but attractive would fit the bill. If not rugosa, what would you recommend? Thanks! I have a slightly alkaline soil, and the garden slopes down to the end of the lawn.Asked on 30/3/2013 by Samantha58 from North Norfolk
I think one of the Berberis would be ideal. One that grows to just 60cm is Berberis thunbergii f. atropurpurea 'Atropurpurea Nana'. It will hold its foliage throughout the year and has golden yellow flowers in spring, followed by bluish-purple berries in autumn. Please click on the following link to go straight to it.

Q:Madame 'Alfred Carriere' Rose- does it have thorns?
Hi there, the above rose would seem perfect for my garden, but I need to know one thing, ....is it thorny? I particularly want a thorny rose as I am planting it as a security aspect as well as for its looks. Many thanks, SharonAsked on 14/4/2010 by Sharon Boothroyde
A:Hello Sharon, These are beautiful roses and they do have thorns, but not masses of them. If you want as particularly thorny rose, then the Rosa rugosa species are the best - but they are large shrubs rather than climbers. http://www.crocus.co.uk/search/_/search.rugosa/ I hope this helps.

Q:Disease resistant roses for a coastal area
Hi, Before I order some roses I need some information on which ones would grow well in our local conditions. I live in the far west of Cornwall, the soil is fairly acid,- Camellias grow well here. It's windy and the air is quite salt laden since we're not far from the sea. I'd like disease resistant plants if possilbe since the climbing roses by the cottage door do get black spot. At the moment, even here, where we hardly ever have a frost, there is 4 inches of snow on the ground and the temperature has been 0 to minus 1 for the past five days.... the postman hasn't reached us for four days! ...So, I won't be ordering the roses right now. Thanks, TrudiAsked on 9/1/2010 by Trudi Gurling
A:Hello Trudi, All roses need similar growing conditions, although a couple are slightly more tolerant of shade than others. If you click on the following link it will take you to all our roses that show some resistance to diseases. http://www.crocus.co.uk/plants/_/roses/plcid.8/vid.243/ I hope this helps.

Q:Hedging and Osmanthus plants
Dear Crocus, I am looking for two Osmanthus burkwoodii plants but notice on your website that you only offer them for sale in 2 litre size. Do you have any larger Osmanthus burkwoodii plants? I am also looking for suggestions on which plants would make a good hedge. I am looking for something hardy, able to stand the frost, evergreen, not poisonous to horses and if possible, not just green possibly red / purple or variegated, any thoughts? Also, as these plants are grown in Surrey, will they be suitable to grow in the Scottish Borders? Many thanks, JaneAsked on 29/11/2009 by Janey Mitch
A:Hello Jane, I'm afraid we have all the plants we sell displayed on our website so we do not sell larger sizes of the Osmanthus. As for the hedging, if you click on the link below it will take you to our full range of hedging plants. Unfortunately we do not have anything that meets all your criteria, but if you click on the smaller images it will give you a lot more information on hardiness levels (fully hardy means they can cope with the weather in Scotland) as well as leaf colour etc. Unfortunately though I do not have a list of plants which are not poisonous to horses, but your local vet may be able to help you with this. http://www.crocus.co.uk/plants/_/hedging/plcid.30/ Best regards, Helen Plant DoctorAnswered on 30/11/2009 by Crocus Helpdesk
Q:Prickly hedge required
Dear Crocus, I am looking to grow a hedge in my garden. The purpose is that it looks good and stops intruders climbing over a wall so I would like nice prickly plants. I have looked at the 'Firethorns' - Pyracanthas, but are there any others that you sell that you would recommend? The location is on top of a wall and against a fence. I will either use troughs, railway sleeper or something similar to create a bed which I will then have to feed the plants myself. Are these plants suitable? Thank you for your assistance. AndrewAsked on 27/10/2009 by Andrew Baldwin
A:Hello Andrew, I am worried about the area you want to plant in which sounds very small. For the plants to grow to create a healthy hedge they will need space and soil depth. Pyracantha is good for hedging, but you may also like to look at Rosa rugosa or Berberis. Hope this helps Helen Plant DoctorAnswered on 28/10/2009 by Crocus Helpdesk
A:Hello Andrew, there are no hard and fast rules, but hedges are densely planted so there is a lot of competition for water, light and nutrients. Therefore I can only say the bigger the planter the better, and the smaller the root area, the higher the maintenance will be and the harder it will be to keep them alive. I'm sorry not to be more help. Helen Plant DoctorAnswered on 28/10/2009 by Andrew Baldwin
A:Hi Helen, Many thanks for your reply. What is the minimum soil depth, is
30-60 cm going to be workable if the hedge only needs to be approx 90cm
tall? Thank youAnswered on 27/10/2009 by Crocus Helpdesk
