Garden Team Blog – January 2021

November to mid-February, is an ideal time to look at tree work in the garden. With leaves removed the branch structure of a tree can be better accessed and with most bulbs and herbaceous perennials lying dormant and protected under the ground, falling branches can do little damage. Conifers put on a new flush of growth in April and deciduous trees tend to lie dormant in the winter months, with sap only again beginning to rise from mid-February onwards. which makes it an ideal time to prune trees.

This January the focus of our tree work has been Topfield (the north facing side of the garden) this area was planted up with trees and shrubs 30-40 years ago. At the time of its initial planting, it was a windswept, exposed, and sloping grass field. Many of the early trees and shrubs planted in this area were chosen for their quick rate of growth and to provide shelter from the wind for more choice specimens such as Camellia and Magnolia.

Jobs in the Garden

With the much-appreciated help of Oliver Peto, who’s has tirelessly and relentlessly put chainsaw to tree. Several conifers that have reached the end of their useful life have been removed creating light and space for the planting below and opening new paths through existing planting. Much dead wood as also been removed from trees in this area and many lower limbs have been removed (crown lifting) so that paths are more accessible. A dead Monkey Puzzle that has stood sentinel at the top of the garden for several years, has also finally been removed.

We have also begun hard pruning some of our camellia collection that are located behind the scenes in our shelter belt nursery. Many of these camellias have reached 4 to 5 metres in height and outgrown their site. So a regenerative prune will bring flowers much closer to the ground and produce lots of fresh cutting material. It is likely that these camellias will not flower for the next two years as camellias flower on previous seasons wood. The plants will also require further pruning to encourage bushyness in future years.

All the woody material that has resulted from this tree work, and there is a considerable amount is then chipped and will be spread on our paths or allowed to rot down and used as a mulch on our flowerbeds.

Now is the time to cut back your herbaceous perennials if you have not done so already. Emerging hellebore flowers and early flowering bulbs look much better in a cleared bed than emerging from dead leaves. The focus of the cutting back has been the areas surrounding the garden entrance, tearoom and herbaceous borders. We have also recently redeveloped/replanted the herbaceous borders, removing old and tired plantings, for new and fresh planting. The theme being blue, silver and white.

We have a new tool shed. One of our old and crumbling potting sheds has been repurposed, having its roof removed and a new roof fitted. Tools which have previously been languishing in our numerous garden buildings have been brought together in one place. It has been long awaited with many thanks to Tony for all his hard work.

In addition to tree pruning, it is also time to prune Wisteria and Roses. This month our famous wisteria arch was pruned, in the hope of a good display come April. Pruning a Wisteria is a complicated task, planning forward into the future as well as the present. Dead, dying and diseased branches are removed and, last season’s growth needs to be pruned back to 3 or 4 buds (the flower buds) which will result in a framework of flowering spurs. If this was not enough some shoots need to be left to tie in for future flower.

Finally, with the Camellias beginning to come out into full flower, we are making a great effort to identify, label and photograph as many plants as possible. There is little point in having over 300 camellias If we don’t know what they are.

Tips for your Garden

  • Continue to cut back herbaceous borders
  • Tidy up glasshouse and polytunnels, remove any dead from plants, it is important to keep good plant hygiene and air movement to prevent against diseased such as mildew and botrytis.
  • Pruning deciduous trees
  • Formative pruning of summer flowering climbing plants.

Plant of the month:  Camellia ‘Jimmy Smart’

This unique and stunning salmon-red camellia, with golden centre, is one of the earliest camellias to flower in the gardening year here in the gardens. It is in prime position next to the garden entrance, welcoming visitors to the garden. It is a seedling raised by Dr James Smart the founder and Creator of Marwood Hill Gardens. It is one of many plants raised and selected by the Dr, and forms part of the newly formed Marwood National Collection. It has a long flower period throughout the month of February.
