Acer palmatum 'Sango-kaku'
coral-bark maple ( syn Acer senkaki )
- Position: lightly, dappled shade
- Soil: fertile, moist, well-drained neutral to acid soil
- Rate of growth: slow-growing
- Flowering period: April to May
- Hardiness: fully hardy
This is one of the best Japanese maples, as it looks fabulous all year round. It has pale green, deeply cut leaves that turn soft shades of yellow in autumn, and it also looks gorgeous in winter, after all the leaves have fallen, when its new shoots glow coral-red in the winter sunlight. Try it next to a path, or in front of a window, where the autumn and winter colour can be fully appreciated, or as part of a winter border. It needs a shaded, sheltered spot, away from strong winds.
- Garden care: Add a top-dressing of a multi-purpose fertiliser around the base of a newly planted tree in late spring and keep well watered. No routine pruning is required, just remove any dead, damaged or crossing branches in late autumn or winter when they are fully dormant.

Q:Hi - the pot size for this tree is 3 litres, what height will the tree be when it it delivered, it sounds quite small? Are there larger specimins available? And final question - is it suitable for planting in the Winter?
Many thanks!Asked on 24/11/2015 by anneinspace from West London
This is the only size we currently have available and the plants are currently around 30cm in height. They are fully hardy however so can be planted at any time of the year provided the ground is not frozen or waterlogged.Answered on 25/11/2015 by Helen from crocus
Q:Hi, I am looking for a small tree to plant in front of our livingroom window to stop it being so exposed and provide a little privacy. /i don't want an evergreen as I don't want to completely block out the view and since it is in a prominent poosition it needs to have year round interest. I am particulary after something with red or orange bark to ech the dog wood winter flame we have on the other side of the garden but I'm open to other options. Would Sango-kaku be a good option? Are there others you can recomend? Is it difficult to look after? Thank you!Asked on 12/11/2015 by gardendreams from oldham
That sounds a lovely idea, although eventually it can grow to 6m x 5m, but it is very slow growing.
This is not a hard plant to grow but it has certain requirements, such as a neutral to acidic soil which is moist, fertile, and well draining in a sheltered situation where it is not going to be caught by winds, or baked in the sun.
Hope this helpsAnswered on 13/11/2015 by Anonymous from crocus
Q:Problems with my Passionfruit clmber after cutting back, and an Acer that I moved?
Hi Crocus I've recently had my garden designed and am very pleased with the results, (plus many good Crocus plants). Unfortunately, my gardener had to cut back my Passionfruit climber which is about 7 years old. Whilst the other climbers (Honeysuckle / Jasmine) are starting to bud and grow back the Passionflower doesn't seem to be, - is there anything I can do to encourage growth? Also I have an Acer, (about 5 years old), which was frazzled by the sun last summer when I moved it from it's semi-shaded pot, into the ground in more sun. Now there are only a couple of buds that are appearing on the ends of some of the old stems, - should I cut back the ones that don't appear to be shooting, or again is there something I can do to encourage growth? Thanks VickieAsked on 12/4/2010 by Vickie Kirk
A:Hello Vickie, Passionfruits often don't recover from being cut back really hard, but the only thing you can do now is wait and see if it rallies around. I would be reluctant to feed it or try to push it, but do make sure it is watered when the soil gets reasonably dry. If however there are still no signs of growth by early June, then I doubt it will come good, so it may need to be replaced. As for the Acer, I would be patient and see if it does start the shoot from the other branches, but again by early June you will be able to see clearly if certain stems are dead and if they need to be cut out. Same rules apply here as to feeding and watering. I hope this helps. Helen Plant DoctorAnswered on 12/4/2010 by Crocus Helpdesk
Q:Tree for screening, and a white rose.....
Dear Crocus, Please could you advise me? I would like to plant a tree (or other) to screen out the neighbours house. My concern is to find a tree which can be planted near to our house without causing any problems to the building or the patio area. To the side of our house we have a paved path, about 0.5m wide and about 1m of lawn up to the fence. There is sun in the morning and again after about 2pm. I am also looking to find a white rose, long flowering and easy to maintain to reach about 1m high. Sunny position. Our soil is a bit chalky. Hope you can make some suggestions so that I can put my order in online. With thanks, MariaAsked on 22/2/2010 by M Dixon
A:Hello Maria, Ideally you should aim to plant a tree at least as far away from the house as its eventual height, so if a tree grows to 5m tall at maturity, you should plant it 5m away from your home. This rule however is made to be broken, however you should keep in mind that all large plants have the potential to lift patios or cause damage to unstable walls if the soil is very heavy or the plants get large. Therefore you need to decide if the need for privacy is greater than the risk. If you do decide to go ahead, I would opt for any of the following as they don't tend to become problematic. Acer palmatum cultivars http://www.crocus.co.uk/search/_/search.acer-palmatum/ or Pyrus salicifolia Pendula http://www.crocus.co.uk/plants/_/trees/other-trees/deciduous/small-garden-trees/ok-for-small-gardens/pyrus-salicifolia-pendula/classid.4672/ As for the rose, Polar Star is great http://www.crocus.co.uk/plants/_/shrubs/roses/hybrid-tea-roses/bush-rose/modern-hybrid-t-&-floribunda/rosa-polar-star-=-tanlarpost-pbr/classid.1242/ I hope this helps.

Q:Specimen Ceanothus or another large bushy shrub....
Good afternoon, When I was first looking for a Ceanothus to replace the one we have in our front garden, I looked on your website, but you only had small ones. Our once lovely Ceanothus has been pruned out of all recognition again this year, as I planted it a bit too near our boundary when it was a baby. I know it may come back, but it is getting ridiculous as every time it grows back it has to be cut back again severely and then ooks a mess for most of the year. Have you got a nice, tall, bushy Ceanothus to replace it? I love my Ceanothus but perhaps if you don't have a big one, do you have another large, flowering shrub as an alternative? Hope you can help Regards MargaretAsked on 5/12/2009 by D DRAKETT
A:Hello Margaret, it is rare to find larger sized Ceanothus as they are usually quite short-lived and don't normally live longer than 6 - 8 years. We do have a selection of larger shrubs on our site like Hamamelis, Hydrangeas, Magnolias, Acer, Cornus, Cotinus, Philadelphus, Syringa and Viburnum, so you may find something of interest. They will be listed in this section. http://www.crocus.co.uk/plants/ I hope this helps. Helen Plant DoctorAnswered on 8/12/2009 by Crocus Helpdesk
Q:Acers for a south-facing garden, or another small tree?
Hello, We live in a mid-terrace house and our garden is south facing. We're looking to get small trees that could live happily in pots and really like Acers. We like them because of the wondeful autumn foliage, but the indication that I seem to be getting from looking at your website is that Acers don't like south-facing, full-sun gardens. What could we do if we wanted Acers, or what would you recommend instead? We're looking for a smallish tree, with nice, colorful foliage. Cheers and regards, RichardAsked on 20/11/2009 by Richard Cote
A:Hello Richard, If you want to grow Acer palmatums then you will need to provide some light shade for them during the hottest part of the day - often you can plant them closer to a wall or fence which will offer some protection. Alternatively you can click on the following link to go to all our small trees, which will flourish in a south facing aspect. http://www.crocus.co.uk/plants/_/trees/plcid.7/vid.37/vid.187/ I hope this helps.

Q:Will an Acer, Weeping Willlow and Beech grow in clay soil?
Hello, Will a Japanese Maple, Weeping Willow and a Copper Beech do well in deeply clay soil ? Thank youAsked on 15/10/2009 by Wendy Hall
A:Hello There, As long as the soil does not remain waterlogged for any length of time and you can dig in lots of sharp sand and composted organic matter, these plants should be fine. The willow will olerate a little more moisture than the other two. I hope this helps. Helen Plant DoctorAnswered on 16/10/2009 by Wendy Hall

Q:Large Yellow Leaved and Deciduous Tree please...
Dear Team, My large magnificent Robinia pseudoacacia has died and I read in the Hilliers newsletter that I am not alone. I need to fill the gap with something substantial, impressive and yellow, but I am advised, naturally, not to repeat with another Robinia pseudoacacia for fear of the same disease. I am impressed with your Catalpa big. 'Aurea'. Before I finalise the decision however, have you any other suggestions, please? Regards, GeoffreyAsked on 28/9/2009 by Anonymous
A:Hello Geoffrey, If you click on the following link it will take you to the few tress we sell that have yellow foliage http://www.crocus.co.uk/plants/_/trees/plcid.7/vid.48/ I'm afraid though the best replacement will be determined by what might have killed your Robinia as some other plants may be susceptible too. I hope this helps. Helen Plant DoctorAnswered on 28/9/2009 by Crocus Helpdesk
Q:Fungus and dry leaves on Acer?
Hi there, I have noticed in the last week that one of my Acers has developed very dry yellowed leaves and a white soft fungus on its bark, what do you think this could be? My other Acers are fine, but I'm worried that this will spread. What can I do to remove/avoid this? Kind regardsAsked on 14/9/2009 by nikki craig
A:Hello There, Acers are prone to a number of pests and diseases, but I suspect yours is suffering from a wooly scale - just click on the following link for more information. http://www.crocus.co.uk/pestsanddiseases/_/pests-and-diseases/stems/artcat.6/ I hope this helps.
