Cold and exposed garden

Posted: 09/04/2015 at 21:37

Rather than blocking the wind you need to filter it as blocking just creates eddies and swirls that do all the more damage.   I have a very exposed garden that gets every gale going and usually goes down to -15C in a normal winter and has been down to -32C.  My soil is mostly fertile, alkaline loam on a clay sub soil so varying drainage and moisture levels.   I use trellis panels to separate bits of garden and further reduce wind strength and have a hawthorn hedge at the windiest end of the garden and assorted shrubs and a holly hedge elsewhere though that has struggled to establish owing to very cold winters after it was planted and then the neighbouring cows eating the new shoots.

I put windbreak fabric along the entire northwest boundary this year and the added wind resistance has done wonders for the fruit bushes in my veg patch and the ornamental shrubs in the rest of the garden but in the recent gales the posts of the metal mesh boundary fence were blown to 45° angles despite having concrete boots and have had to be propped up with struts.

I find evergreen shrubs struggle except for one or two conifers in sheltered positions.   A snowball viburnum is still here but all its tinus cousins and an eleagnus, chosiya and a few others all froze to death.   I have 4 forms of cornus which do very well every year and also philadelphus, sambucus, weigelias, euonymous europa, buddleia, physocarpus, cotinus, salix, lilac plus a prunus cerasifera, betula jaquemontii, parrotia persica, gingko biloba, a toothache tree and an acer negundo plus two crab apples and a damson tree .   It remains to be seen how my growing collection of hydrangea paniculatas are doing as they have yet to show any buds this spring.

I grow a wide range of perennials - aquilegia, astrantias, astilbes, astilboides, bergenias, cornflowers, achilleas, phlox, lysimachias, hemerocallis, irises, dicentras, geraniums, geums, potentillas, anemones, primulas, lychnis, hellebores, ligularias, pulmonarias, hostas, persicarias and so on.  They just take their time coming through in spring.   No sign of hostas yet, for example, and plenty of others still hibernating. 

I can grow miscanthus, carex and molinia grasses but not pennisetum or stipas which are too nesh.

I can't grow group 1 clematis alpinas or montanas or macropetalas as they get frozen or blasted at flowering time but have Red Robin and Red Ballon doing very well.  There are some group 3s which get pruned to the base in March and which are hardy to -25C and do very well here and I have a few group 2s which I treat as group 3s and prune hard.

Some roses struggle and others do well but I've had to lift some and pot them up so they can spend winter in the greenhouse or shed.

Shelter belts, mulching and patience are what you need.

Screening

In Belgium I've seen pleached hedging made from hornbeam, catalpa, tilias and photinias.   I believe it's possible with pear too and I've seen a copper beech one at Chelsea Flower show -

It will take some time to grow and you will need a wooden framework for the initial training till it grows and supports itself but a well made frame is attractive in itself. You can buy the trees already started from specialist nurseries which would speed things up but probably cost a lot.

Crocus bulbs

Posted: 08/04/2015 at 20:21

All bulbs need to be left with their foliage on for at least 6 weeks after flowering finishes so their leaves can manufacture food and their roots take up moisture and nutrients from the soil to build up the bulb for newt year's flowers.  

Unless you're a professional with proper storage facilities, if you lift and store small bulbs such as crocuses, even after the six weeks, they risk dehydrating and dying so it's best to transplant them to new homes whilst still green or as soon as the foliage has died.

OH has forked over one of our long raised beds in the veggie plot while I measured and cut and then screwed in place the buttress posts to prop up our back fence which was blown to drunken angles in the recent gales.   I've also weeded my bed of ornamental carex buchanii and other grass like plants and added a few more carex to fill gaps.

Planted out some of my recent perennial acquisitions in a bed I cleared of an excess of hardy geraniums 3 weeks ago.   Left it fallow to grow any new weeds from naughty couch grass and nettle roots but it was OK.   It's only 2m by 4 and I left some aconitums, hemerocallis, aquilegais and hellebores in there but even with the twenty new perennials and some additional transplanted stuff it still looks very bare.   I hope they all grow well and fill out soon.

Didn't have time to sow my PSB and ornamentals but there's always tomorrow, or the day after.......

Clematis

Posted: 06/04/2015 at 20:19

No rooting hormone here but, whilst pruning back the last of teh clems to show new growth I took 5 cuttings each of 4 of them.  I used compost mixed with grit in terracotta pots and put the cuttings round the edge.   Tomorrow they'll be put in the propagator after I've pricked out the chilies.

Fingers crossed it works for yours and mine and anyone else having a go.

Still very cold here today and with a naughty north-easterly making it feel worse so I've spent some time gluing polystyrene insulation panels to the garage door, moved the trays of spring onion and beetroot seeds to the greenhouse along with the onion sets in their little pots, pruned 3 more clems back now they're showing growth and taken cuttings of 4 clems.

That meant I had to check the internet for one of the names and lo and behold I've ordered 3 new scented clems from my favourite supplier whose website handily lists hardiness in temps below 0C.   Checked the recently butchered hosta divisions and everyone is doing fine as are the recently potted up roses I rescued from the borders last autumn.  They were struggling so spent the winter in the greenhouse and it seems to have done the trick - Geoff Hamilton, Munstead Wood and Benjamin Britten do not like the cold winds here.   

 

Gardening by the Moon

Thanks.   Looking forward to more info and tips and am pleased you enjoyed your course.

I sowed 6 varieties of toms and 4 of chillies and 1 yellow sweet pepper in propagators a couple of weeks ago on a fruit day and every seed has germinated except for one beefsteak tomato.   Most of the toms popped after just a week and have already been potted on into cells.    

Salads and cabbages sown on an earlier leaf day are doing well and I'm now waiting for broad beans to show their noses.   Yesterday I started off red onion sets in peat pots and sowed some red spring onions.  Tomorrow it'll be purple sprouting and flowers.   Much too cold today and a frost expected tonight so I need to wait for a warmer day to move babies from the greenhouse to cold frames to make space for new seed trays.

climbing roses

Posted: 06/04/2015 at 14:17

Just lean the roses back at a slight angle when you plant them and then tie in the flexible new stems as they grow.  They'll be fine.  Remember to give them well prepared soil with lots of added garden compost and well-rotted manure to grow their roots and find food and water.  

They are very hungry plants so will appreciate an annual spring feed of rose fertiliser and an occasional liquid tonic of tomato food between April and the end of June.

Be careful Oltyke and Hostafan.  Clematis fever is easy to catch and there's no real cure.   I have learned to restrict myself though after losing all my alpinas and montanas and winter flowering clems to early, heavy frosts.   I now concentrate on Group 2s and 3s which will withstand -25C.

It has been perishing here today with strong, bitter easterly winds and a high of 5C so I have limited myself to checking on the seedlings in the greenhouse, setting up a new potting bench in the shed and tidying up the work area at the back of the house.   Tomorrow should be warmer and by Tuesday we should get into double figures so I'm hoping to get the veggie beds forked and raked for the new babies.

What can I do under this hedge?

Posted: 04/04/2015 at 17:26

Pine forest floors tend not to be as densely planted as hedges in gardens so light and air and water can get in there as well as decaying plant material from other trees and plants which helps with soil fertility.    If you go to a pine forest planted by the forestry commission or any other commercial venture the trees are so tightly packed that nothing else grows and teher's no wildlife either - hence the recent move to bigger spacing and mixed woodland plantations.

Making a deep bed under them isn't an option as the extra depth of soil and compost to grow things will rot and damage the trunks of the conifers which the OP wants to keep.
