November was a month of intensive clearance jobs. For most of the month the whole team worked together, moving through large areas of the garden, clearing weeds and cutting back anything that looked untidy. We began in the fernery at the bottom of the garden where we cut back and removed swathes of Blechnum capense (Palm-leaf Fern). Our garden curator Mike decided that the area would benefit from being opened up to expose a number of tree ferns planted in the area and to create space in which to plant new specimen ferns. The Blechnum (which had grown to around six feet in height) had not been cut back for about six years and was full of dead leaf litter. Cutting it back to just above the ground will have the effect of rejuvenating the plants, creating a low carpet of fresh new fronds that will sit attractively below the tree ferns.

Once we had finished clearing the fernery, I spent much of the following week trimming the large Eleagnus x reflexa (Silverberry/Oleaster) bushes below the Wollemi Lawn. I quickly decided that Eleagnus is my second least favourite hedging plant to deal with, (after Pyracantha) due to its incredibly interwoven growth and occasional long thorns, which left me with some lovely deep puncture wounds, sustained while attempting to unravel the impossibly tangled mess. In spite of this, the hedges do look far smarter now that the long leggy growth has been removed.

At the end of the month we continued with our major clearance work, moving progressively through the garden from the entrance to the crossroads below the Mediterranean Garden. Despite the fact that much of this area was only planted within the last couple of years, it was decided that many of the shrubs had outgrown the space and that the area would benefit from being replanted. Beginning at the garden entrance, we removed a number of large Argyranthemum frutescens ‘Canarii’ (Marguerites), Euryops pectinatus (Golden Daisy Bush) and Rosmarinus officinalis (Rosemary) bushes, before extensively weeding and digging over the beds. Moving further into the garden towards the crossroads, we spent more time cutting plants back, rather than removing them completely. This area is planted with an array of particularly fragrant plants including Coleonema pulchellum (Confetti Bush), Eriocephalus africanus (Cape Snowbush) and Pelargonium tomentosum (Peppermint Geranium), which gave off an amazing aroma as they were trimmed and pruned. Also planted in this area is a small collection of interesting rush and grass-like plants including Arunda donax (Giant Cane) and Baloskion tetraphyllum (Tassel Rope-rush) and these were cut back to just above the ground to regenerate. Around the crossroads themselves, we removed a significant amount of Aloe striatula (Hardy Aloe), a Grevillea rosmarinifolia (Rosemary Grevillea), and pruned and deadheaded a number of Protea cynaroides (King Protea) and Protea ‘Pink Ice’. Twisted through all of this was a mass of Osteospermum ‘Tresco Peggy’ (an unofficial local name given to this particular purple African Daisy, named after estate owner, Robert Dorrien-Smith’s mother), which was reduced quite significantly as it is relatively fast growing and will soon recolonise the area. All of this work created some large open areas of bare soil, which were then edged with young new Rosemary plants to create formality. The remainder of the planting should be carried out some time in early spring.

Looking Down On The Old Abbey

One of my university lecturers once told me that I should seriously consider writing for a horticultural magazine. However, I think that I would probably be very hard pushed to find any publication that would be happy to receive my entry for their October issue in early December. Let’s leave it there shall we.

The seasonal formalities really begin here. Following on from September, cutting back, tidying up and major clearance projects are the order of the day. In this respect, Tresco Abbey Garden is much the same as any other garden in and around the UK at this time of year, although there are significantly fewer leaves falling, as many of the large trees in the garden are evergreen and therefore leaf raking fortunately doesn’t feature too heavily. (A job which I know some of my friends in other gardens across the country have been enjoying tremendously). A large proportion of our time during the month was devoted to hedging. My confidence with this grew very quickly and once I started looking down, I discovered that the job offered some very impressive views of the garden that few have the pleasure of experiencing. The image above was taken from the top of the Scillonian hedge; the tallest of all the hedges in the garden at somewhere between 30 and 35 feet in height. I wish I had had a wide angle lens with me at the top of the ladder to fit in the amazing view across the treetops to the sea and the islands beyond. You’ll just have to imagine it. I have recently been given a much better camera so when the sun comes back I will do another post showing some of the more spectacular views across Tresco. 

The Isles of Scilly are one of the last bastions of the Elm tree in the UK. Completely unaffected by Dutch Elm Disease, three species of Elm grow in and around the garden. These are the English Elm (Ulmus procera), the Cornish Elm (U. minor subsp. angustifolia) and the Wych Elm (U. glabra). One of the more major projects of the month was the pollarding of two small belts of Elm and Olearia trees, in order to improve views from the Abbey. For those of us not trained in how to use a chainsaw, this meant a lot of groundwork, removing brush to create access and then clearing and chipping an enormous amount of felled wood. Once the job was complete, Andy our head gardener took time to show us the basics of tree climbing. The climbing method that we were using was the ‘thrusting method’ which kept us mildly entertained for a short while. Once we had pulled ourselves back together, the method involved throwing a rope over a suitable branch and attaching it back to the climber through a friction hitch. The climber then pulls down on the rope, while simultaneously thrusting upwards with the hips and sliding the friction hitch up the rope being pulled to hold the weight. The position is fairly horizontal and the climber is effectively able to walk up the trunk of the tree. I found this quite easy and a lot of fun. I look forward to climbing something bigger next time.

One of my favourite jobs of the month was cutting back and digging out a large amount of Giant Gunnera (Gunnera tinctoria). I find working with Gunnera very satisfying as it has such an instant impact and makes you feel like you’ve done far much more work than you actually have. I was unaware at the time I was working with them, but apparently the leaf stalks of this particular species are edible and are cultivated as a food crop in South America. I wish I had known, I could have made a massive crumble.

October also saw the arrival of two visiting student gardeners. Laura, who has previously worked at the beautiful West Dean garden in West-Sussex will be with us for a couple of months and Joe took a well earned break from trimming Yew topiary at Levens Hall in the Lake District, to come and trim Evergreen Oak and Olearia hedges on Tresco. You can read Joe’s blogs about his experience here.
