I have planted griselinia in a deep raised bed created along a low wall (3ft) to provide screening from neighbours. (Final height of hedge req. 4ft ) I realise it is a vigorous grower and I do not want it bare at the base. Planted last month 18inches high should I cut back now or leave until the spring? and can I grow any ground cover in with it.
As the hedge is 35 years old with very dense roots is it practical to just cut the existing hedge and try to plant something between the old stumps. Any recommendations on what is best to plant as a replacement and when is the best time to do so ?
I have an escallonia hedge and its planted with two years it died with the bad frost but thankfully i got it back with feeding it chicken manure for the roots and tomato feed for the leaves and weeding around it but now my problem is its growing high and i have a beautiful pink flower at the moment but its bare at the bottom and its not full if you know what i mean please help what do i do??
I planted a Griselinia hedge last year and I would like to know what fertiliser you would recommend for strong, fast growth.
About 2 months ago I planted 196 potted laurel shrubs to form a hedge. All was well until 2 weeks ago when I noticed the leaves on 5 or 6 plants were being eaten as well as turning yellow then brown. These plants are now under stress. I have clipped any grass around the plants to try and help them survive.
Is it possible to transplant hedging this time of year? what hedges would you recommend for shaded areas?what climbers would you recommend for shaded areas?
I have a large arrangement of Buxus shrubs that appear to be continually deteriorating after the frost. The leaves are turning yellow/brown and are extremely dry. I have been watering and waiting to see if there is any recovery but the problem seems to be spreading further up through the plants from the roots. Is there anything I can do or any treatment I can give them. I would hate to loose them as the collection would be very difficult and very expensive to replace.
I have a problem with a row of hedging I have had recently planted. I'm by no means a gardening expert but I believe the type of hedging to be prunus laurocerasus. It was planted roughly 16 weeks ago. The leaves on most of the plants have turned yellow are now shedding profusely. The hedge is situated next to a wall in the back garden and the garden itself has got underlay and loose stone on top. Please see the attached photo. This was taken when the hedges were first planted. Can you think of or see a reason as to why the plants are dying? I have a dog in the garden also and I was wondering if it could be his urine thats causing the damage? Can you tell if the hedge will recover?
I have a 5 yr old Griselinia hedge that got badly damaged by the frost. What can i do ?
i want to snip off some pieces of existing fushia shrub i have. is it too late to simply stick it in the ground, can i make a hedge out of it, if so, how far apart should it be set?
In a previous message I asked if cutting back the top/new growth of a copper beach hedge will help it to thicken at the base. I belive your answer was no. All the other advise I received from garden centres suggested I cut back the new growth in late July to encourage more growth further down? Does this make sense... I need/want the hedge to thicken and not grow any higher than 5 feet. Currently the plants are young 4 ft plants......
I have 3 yr laurel hedge and for the first time some of the plants have sprouted a white flower.Is this something to worry about as some of the affected plants are otherwise healthy while the rest have had their leaves turn yellow.
I recently planted a laurel hedge as a screen. The plants are 3 - 4 ft high. Should I cut them back/down to promote growth at bottom.
I recently (last week in march) planted a copper beach hedge inside a 3 ft high pariimiter wall. 90% of the trees are showing signs of growth i.e. sprouting or new leaves. I'm hoping the other 10% will come good in the next few weeks. If they dont what should I do. Should I also trim the tops to enable growth lower down. I am a novice gardener. The plantts are ~ 3 - 4 ft high...
I planted small conifers 25 years ago. With constant cutting and shaping these grew into a beautiful manicured hedge. This year alot of brown patches have appeared in the hedge. Has it run its course or has the harsh winter effected it? Is there anything I can do now to nurse it back to health?
