You may remember that I started my last article commenting on the ferocious winds we had experienced in our gardens during autumn, and now the start of this New Year has been no exception to that rule either. Some of the fiercest gales for many years tore across the north during the first few days of January coupled with torrential rain and I am sure that almost every garden has suffered in some way or another. We had just started planting some of the new trees in our lower garden on New Year’s Day and after cutting through the top 2-3 inches of turf that was sodden, the ground underneath was quite friable and we were able to plant three young specimens of the lovely Himalayan Birch, Betula utilis var. jacquemontii ‘Doorenbos’. This is an excellent form with a striking whitened trunk, even at a young age in this variety, and has received the Award of Garden Merit from the Royal Horticultural Society (RHS). Lo and behold, after further heavy overnight rain, they were each sitting in a puddle of water next day so a quick emergency slit trench had to be cut leading away from each planting hole so as to divert the surface water. They will not mind this saturating as they do worry about having their ‘feet wet’ so to speak, but in early March I will cut them back, almost stooling them, in order to encourage lots of lovely brightly coloured new shoots in order to provide a lovely display of the bare stems next winter. This is something that you want to undertake in alternate years and it ensures that the growth is always young and brightly coloured, not becoming old and congested with the characteristic muddy brown stems and only short new shoots of red or yellow at the top of tired-looking bushes.
After staking the birch we had secured them with an adjustable plastic tree tie nailed to the stake, this being on the windward side of the plant so as the growth is blown away from the stake in a storm. When using any of these forms of ties it is always essential that after a year or two you regularly check them for stem expansion so as they can be adjusted to give more room for the trunk to expand further and not cause a growth constriction and damage to the stem. It is really distressing when you see good trees damaged through lack of proper attention following planting.

After experiencing any wild weather it is always wise to check on young planted trees and shrubs to check that they have not been blown loose in the soil and gently firm in again with the heel of your boot. Check that all ties are firmly in place and also that no loosened garden fencing or garden structures have caused damage to plants. Remove these misplaced branches with a sharp saw, or garden loppers with the lighter growth, and it will give the plant a better shape for the coming years. When pruning branches above your head height, then use a backward cutting pruning saw that can also be attached to an arm so as to make the task much easier with less effort. There is nothing worse than trying to exert forward pressure above your own height and it is also not very effective with cutting progress either. For larger wounds treat the cut surface with a fungicidal paint, detailed in the last issue.
Now with everything appearing to be starting into growth and flower much earlier this season then it is certainly time enough to think about dividing and propagating perennial plants from your borders. After the last two winters when we have experienced a total shutdown in our gardens, this year is the exact opposite. We have had primroses and polyanthus flowering all winter, spring-flowering shrubs showing off early flowers in mid-winter and many bulbs appearing through ground a good month early. When you read books and gardening articles it often mentions dividing and replanting herbaceous perennials during autumn but you often find that the author is from the south, whereas up north it is far wiser to wait until early March when the soil is warming up and there is less cold, sleety rain falling from the skies. Therefore the newly divided plants are replanted into much better conditions than having to sit though a cold, wet winter with no proper root contact into the soil with resultant plant losses occurring.

We are tackling the long border (or Liz’s Border) at the bottom of the garden where the existing border was widened three years ago and a lot of plants hurriedly transplanted into the newly dug frontage extension. So now we are going to move some of the larger plants to the back and vice-versa smaller plants from the front of the old border to the front of the new border, but at the same time divide some of the well established clumps. Pretty well all perennial herbaceous plants appreciate being divided, although there are a few exceptions that hate being disturbed and sulk for some years afterwards. So those that you do not touch are Paeonia, Helleborus, bulbous plants like Trillium and Erythronium, and woody-based silver leaved sub-shrubs such as Artemisia and Santolina. These can just have old foliage removed and a good topdressing of compost and a little organic fertilizer applied in late February so it is washed into the soil before growth starts again. Also if you have variegated leaf forms of plants that propagate from root cuttings such as Phlox paniculata then do not divide, as these will throw up countless new shoots, all green-leaved. If you want to propagate these true to type, then take some cuttings of new growth in spring with a sharp knife, 3-4 inches long, insert around the edge of a pot, water and place in a propagator or closed cold frame and they will root in about two weeks, for potting during summer and to be planted out in autumn.

With established clumps of perennials, determine beforehand where they are to be replanted if not in their original site and get that prepared in readiness with some good garden compost or well rotted manure incorporated before planting. Spread a groundsheet onto the lawn or path so as to work in a clean and methodical manner and then proceed to lift the clumps. They will often split up as you divide them so clearly label each group of clumps, as many dormant roots look very similar to the untrained eye, especially so if you are dealing with several clumps of the same type of plant but with differing varieties, i.e. Phlox, Asters (Michaelmas Daisies), Crocosmia, etc. You will find that the growth towards the middle of the clumps is less vigorous and poorer rooted, so discard these onto the compost heap and only replant the strong, vigorous divisions from around the outside of the old clump. Before replanting into their new site, always make sure that any perennial weeds are removed at the same time, especially if lodged in between growth in the clumps, and this especially applies to creeping buttercup, couch grass, ground elder, bindweed which can all be teased out in the replanting process and deposited in your local authority’s green recycling bin, not in your compost heap. Always choose an odd number of divisions for replanting and then you avoid having a rectangular-looking clump as a result. Firm each division well into the ground and if we do experience dry weather, as we sometimes can in March, then give a good soaking afterwards from the watering can, plus make sure they have about a handful per square yard of a good organic general fertilizer.
With bulbous plants such as Crocosmia there are two distinctly different types of plant. There are those varieties such as the many types of “Monbretia” which produce many small ‘cormlets’ from the mother corm and there are those of the broader-leaved Crocosmia masonorium types where the new corm stacks up on top of the previous years corms, a bit like insulator cups on an electricity pylon. With the former, break off some of the youngest clumps of corms and replant 2-3 inches deep, but with the latter type break off the top three corms and plant back at least 6 inches deep. This deeper planting ensures that the resultant growth is well supported in the ground and grows erect. You often see these types such as ‘Lucifer’ flopping forward in borders when the plants have been left undisturbed for many years and the youngest corm with the growth tip is only just below the soil surface, giving little support for the flower stem.
In the next edition I will be covering The Yorkshire Dales Millennium Trust and their wildflower meadows, RHS National Gardening Week and previewing Harrogate Flower Show.
