Re: Construction near a Beech Hedge

from Mark Gregory

Hi There...
not really a problem here.as the hedge is only 2m high.it's roots are not that developed. and even if there is a little stress.it will bounce back quickly. I would say approx no nearer than 300mm from the nearest face of the hedge..before you dig,give the hedge a good prune that will compansate for any damage to the root system that you may cause.also if you have an option do the work after leaf fall..if not water the hedge well as the work proceeds..
don't lose sleep on this one
happy digging.

Re: climbing clematis and rose

from Mark Gregory

Difficult call that one..most plants that like to flower will want to turn south! wouldn't you? you can try and encourage by pruning.and things are never so black and white..so do not be put off..pick your rose, and clematis to compliment.(remember to plant the roots in deep shade.and plant deeper than you would think, ie about 100mm below the surface.it avoids clematis wilt and they really love it and do much better..
hope that is of some help...

Re: Hostile Roof Terrace

from Mark Gregory

before you get going..check the weight loading..if it's new there will be calculations that will tell you what and where you can load the roof...take heed.if it's old take my advise and consult a local structural engineer for a couple of hundered pounds you will be pointed in the right direction..
you should also consider a simple irrigation system to the terrace..also think about the containers.you can make them out of marine ply, line them with plastic and even paint or render them..the options are endless..but you can make them big enough and also insulate them with sheet insulation material.this will help the pots not freezing.
think about plants that will tolerate sun and wind?.
think thick waxy leaves.(Phormiums for example)
Silver leaves (lavender. staychs, phlomis ,etc) They generally do well in harsh hot conditions.
Thick succulent leaves.(sedums house leeks etc)
hairy leaves
Herbaceous perrenials
Decidous trees like birch.
dwarf pines look cool in containers
Maritime plants such as Griselinia..(bullet proof)
There is so much you can do, and will be succesful...work out the design first.the planting will be fun and is the least of your worries...

Re: Suitable Climbers

from Mark Gregory

Hi There...

firtsly you have to give your climber a fighting chance. spend time preparing well...lots and lots of well rotten manure or good home grown compost well dug in..( possibly a wheel barrow seems too much, but trust me it will help with moisture retention and plant establishment..
because of the aspect you are slightly limited in which plants will give you good success.and you can try others that do not seem suitable at face value...it really depends on local area etc etc..but here are a few safe bets.
Akebia Quinata.(very under used and fab.(deciduos)
Celastrus orbiculatus
Hydrangea petiolaris
Muehlenbeckia complexa
parthenocissus (all spp) be careful it can become a handfull !!
pileostegia viburnoides
rubus henryi var bambusarum
Schizophragma hydrangeoides
to name just a few>>>

Re: Rose 'Schoolgirl'

from Mark Gregory

Hi..
Most roses do well in open aspect and good sun..they also like a good humus rich deep soil.you cannot do much now apart from a liberal mulch of organic material like home made compost or farmyard manure.at least 100mm on the surfave will control moisture and insulate the roots etc..if you have doubts about the soil it is in...when it drops it's leaves..lift it and prepare a pit well for it...lots of organic material well dug in.(at least 450mm deep). a root pruning will also kick start and make it work.
Happy gardening

Re: almond tree

from Mark Gregory

Hi..the plant is still young but it should show signs of flowering...
Think of all fruit,either apples almonds figs etc as reproduction they are seeds after all...by pruning either roots or shoots..(that is why commercially fruit is pruned) it makes the plant think it is dying,so better make good seed, therefore we get a good crop of fruit.bigger better more...the tree is maximising the chances of reproducing itself..try cutting back some of the soft sappy leafy growth.sound dangerous but things like wisteria figs armond etc will respond to a little root pruning..just don't go mad.! sometimes you have to be cruel to be kind.
best of luck

Re: raised bed in shade

from Mark Gregory

Hi...seems there is confusion with the question.ericaceous compost will not give you lime loving plants...it will give you lime hating plants!
deep shade also equals dry shade...go for plant combinations that will work do you want shrubs, or low ground cover? what kind of tree is above the bed?
please come back to me so I can answer correctly

Re: dry shade

from Mark Gregory

Before I get into reccomendation of plants for dry shade..you can significantly improve the situation by adding lots of organic material,well rotten farmyard manure is best or good home made compost...dig in as much as you can a layer of 150mm or more may seem impossible but will retain great moisture and help establishment
the following is not an exstensive list but it will point you in the right direction.
Bergenia.species
Brunnera
epermedium
Lamiuim
pachysandra terminalis
pulmonaria
Waldsteina
most hedra species
Vinca minor
Cyclamen coum
anemone blanda
Eranthis hyemalis

Re: Cherry Tree that seems to think it is autumn already!

from Mark Gregory

Usually a sign of severe stress..trees usually shut themselves down when they cannot manage to get enough water to all the branch structure.which can be normal for a lot of trees when they have had a period of prolonged drought..which we have not..if it had yielded a bumper crop it could be just tired...make sure you give it a very good drink..check that it has re set leaf buds.if it has that is a good sign. cherries do suffer from lots of diseases.such as cankers and silver leaf. which weaken trees, but ususally get into trees through pruning cuts..I doubt that this is the cause..one possible thought is frost damage..we did have some late frosts in may.this has defoliated many trees..but My feeling is it is just tired...think about taking off some of the fruit now..ie 50%. so the energy goes into leaf production and not fruit and reproduction..

Re: Wisteria

from Mark Gregory

Not sure if I'm reading this right..if you want to remove it,you can do it anytime..now will be fine.especially if it re grows. you can spot treat..best to use a marigold glove.sponge and a mix of glyphosate so you can be selective and not dameg other crops or plants..regroth will not be hard to eradicate.
Best of Luck
