Not a good subject for a container, they really do need to be in the ground. These are extremely thirst plants and will be distressed. They are shallow rooted and spread their roots out well beyond the width of the canopy. It's probably not what you want to hear but it would be easier to find another subject to grow in your containers.
How much are you watering them? Willows are very thirsty creatures and I can't imagine how big a planter would be big enough! (even for a dwarf Kilmarnock). They sound distressed.
Hi back in April I bought 3 Kilmarnock dwarf willows and planted them in large planters. All was fine until about a month ago, the bottom leaves started to curl and change colour. As some were trailing the ground I cut them back , now the leaves are turning yellow and dropping. Are the trees distressed, should this be happening around now . Not sure what to do, as I would not like to loose them . Should I replant into larger planters as I want them in planters not the ground. Help please, ta

Apologies for not posting a pic, my phone camera wasn't much good. Anyway, I took some advice on pruning from my local nursery in that they said cut away any branches that are really dark or almost grey (dead looking, in other words), basically aren't a deep mahogany, so pretty much the same as a lot of plants, and I'm pleased to say that even after such a short time it's gone nuts and started sprouting leaves and buds all over the place. :0)
Thought I'd be expecting a year of nothing before some life, but it's all turned out well.
Generally, any shoots coming from below the graft will be from the root stock and should be removed.
The only time I would consider pruning my Kilmarnock Willow would be if/when the growth gets really untidy and reaches across the ground. Salix are very thirsty plants and will need watering in well for the first year. Roots are usually very near the surface. If you are able can you put in some sort of support which will help with wind rock until it become established. I moved one last year - in full leaf that had been in the ground for just 2 years - I was religious about watering and it has recovered and is now just putting out it's catkins.
I just gotten & planted what to all intents & purposes appears to be a form of 4ft dwarf willow, more than likely a Kilmarnock, but as it has many, many shoots flowing down from the top (the top graft looks particularly hefty and well taken judging by the examples of newer ones in B&Q), do I need to prune back some to allow other new ones to grow or existing ones to flourish more? If so, how do I tell exactly which ones to chop and how many?
Also, at about one foot square, the rootball seemed particularly small considering the huge spread on top. The owner said she'd been told the previous house owners had only planted a year ago but had a good spread of foliage last summer. I know Kilmarnocks don't traditionally have a 'normal' vast root system as they are grafted, but is there anything I should be concerned by?
Many thanks, Matt
(I will try to get a picture up when it's daylight.)

Better to be in the ground. If you leave it in its pot your plant will still freeze. Plants in containers are at more of a risk from frost than those in the ground. Your plant will benefit from any rainfall in the ground too, difficult to capture whilst in a container. Yesterday I planted out 2 shrubs despite heavy snow being forecast. Being in Scotland I doubt very much I've seen the end of the frosts either.
Thank you for the reply, one other question if i plant it now and we get a frost in a few days will that harm if?or should i wait till we will not get any more frosts.
So long as your ground is not frozen or waterlogged - now would be fine. They prefer a moist soil - maintain a good watering regime for the first year and you should have no problems.
Hi Lynn, I wonder if you meant to jump into the previous conversation in the Salix caprea 'Kilmarnock' forum? Please click below and then reply to one of the others so they can see your comments Salix caprea Kikmarnock - My Wiilow looks like it is dying

I have exactly the same problem. Mine is in a large container but after all the rain the leaves have turned brown and started to curl. I have just removed the dead leaves but I am very interested to know if this is due to the heavy consistant rain or another problem

Just to follow up on this Kathy....I have had a visitor who immediately recognised the problem with the willow kilmarnock. It had reverted to its root stock below the grafted area as you suggested - (news to me!) and I have now read that this type of willow seeks out water and has a pervasive root system so as it is very near my house I am glad to say it has been removed. My friend advised me to put stump killer on it AND cover the stump in black plastic for up to a year as they are such vigorous rooters...
Check the cambium (scrape the bark lightly, is there a thin green layer underneath? Or is it non existent?). If it is not there the section of branch has died.
What are you fertilizing it with ? Most trees need no / v little fertilizing, unless your soil is poor / something is lackin.g
Hi Angie, I have taken your advice and taken a picture of a leaf (attached,) and have scraped a branch with my finger nail and it is thankfully green underneath. There are buds coming out every where but the leaves have still not dropped off. Have I cause for concern?.
I would suggest it could be one of 2 things. Kilmarnock Willow need moist soil in full sun. I would suspect that drought is your problem. How much water have you been providing? Weather in certain areas ofthe UK have been very dry this summer. Another reason could possibly be Rust, Kilmarnock Willow are notorious for suffering from this. Is it possible to show a close up of the leaves? Is there signs of any new buds forming on the branches? Try scraping the branches with your finger nail to see if the layer underneath is still green - this will give an indication that the plant is still alive. Without a closer picture of your tree it is hard to tell. Angie
I have a kilmarnock salix as does my neighbour. About 6 weeks ago his plant started turning brown as if it was dying. It still had tiny shoots on it and the leaves did not fall off. Then mine did the same. I went to my local garden centre who said it was probably my cat using the trunk as a scratching post but i could not see any damage. the tree is 3 years old and is in a sunny well drained position, and is fertilised and watered regularly. can anyone suggest what it could be as I do not want to lose what is a beautiful focal point in my garden?

Hi Kathy I can't recall but I have already pruned the side shooting branches that are 10ft high back to the trunk twice... I will take a photo tomorrow weather permitting! Thank you! Liz
Hi, Liz, What time of year did you first prune? Should be done in Jan to prevent the kind of weeping you saw. Since 'Kilmarnock' is supposed to be weeping, it sounds like you have some branches that are reverting back to genetically to an upright form. Those branches should most likely be pruned back to the trunk. But, before you do that and before I give advice on where to prune, would you be able to post a photo so I can see exactly what is going on? Kathy C
I read that I needed to prune off side shoots of the small 3ft high Kilmarnock Willow that I found labelled in my garden when I moved in 3.5 yrs ago. I did this and the centre weeping shoots died and since then the side shoots have grown each summer straight up about 10ft, been lopped off by me and grown 10ft again the next summer and look very odd with the dead centre drooping in the middle! I am thinking of removing the tree but can anyone advise me how to return it to its intended shape and size? Thank you!

Hi, Theresa, Those strange green lumps are galls - not uncommon on Kilmarnock willow. They are caused by pest, most likely sawfly, laying eggs in the leaf. The larvae grow in the little mound or gall within the leaf. The majority of the time, they do no real harm to the plant other than make it look unsightly. To help control the pest, you can remove the leaves with galls. Sprays don't tend to work by the time you see the galls since the larvae are protected within the leaf. Kathy C
I am a new amature gardener and have a Kilmarnock Willow in my garden in a large pot. On the whole, the plant is healthy but I have recently noticed some leaves curling and turning brown and others seem to have strange green lumps on them. Cany anone advise me as to what is happening and how to remedy the situation? Please see the attached photos.
Many thanks Theresa
