The gardens of Great Dixter are without doubt my favourite. Dixter has a unique charm and character; it is alive, a continual work in progress, from the experimental planting combinations through to the handful of busy gardeners that flit about like butterflies quickly moving from one bed to the next.
Following on from last July’s ‘Behind the scenes’ tour I decided to book a few 2017 study days with Head Gardener Fergus Garrett. So far I have attended two such days (each attended by around 30 people) and written below are five key notes that I took away from each day. These notes give a flavour of the style of planting at Dixter and the sort of topics you might learn about on a study day. There was a slight cross-over between the two days but I found that to be very helpful as it reiterated a few important things… and as I approach forty my memory isn’t what it was!
Preparing the Garden
- You don’t have to clear spent perennials at the end of autumn, you could leave the seed heads standing. Not only do these enhance winter scenery when all is brown and frosty, but they provide food for wild-birds and habitat for hibernating insects. For planning purposes these dead stems and seed heads remind a gardener of what grows where. This is important for inter-planting of bulbs and self sowers without damaging unseen perennials below ground.
- Apply mulches of organic mushroom compost (be sure that it is organic) and/or horse manure around beds and ‘tickle it in’ with a small fork to maintain good soil conditioning. Add fish blood and bone in the spring.
- Prune back some plants hard – such as Cotinus (smoke bush) if you just want foliage for the year ahead. Prune back climbers that may be taking over another host plant to its detriment.
- Sow seeds in trays in September/October inside glass frames to save time and money in the spring. Many plants will germinate before winter and remain dormant under protective glass. Experiment to see what grows and resists frosts. The extra head start in spring (from early sowing) can improve efficiency in a large garden like Great Dixter.
- Self sowers that appear in beds can be pricked out and potted up into cold frames to over winter as well or they can be relocated / thinned out.
- Plan a long season border which has a continual life throughout the year to please the eye. The border will need both ‘furniture’ (structural perennials / foliage) and flowers.
- Select plants that flower at different times to extend the flowering season and give a constant burst of colour in splashes that succeed each other. Also look out for flowers with long flowering periods of several weeks or months (Geranium Orion) rather than those that flower for a few days (Opium poppies). This makes life easier for gardeners by reducing the burden on continual change.
- Although the big flower shows typically present overflowing gardens of flowers, don’t cram plants together. Give plants enough space to grow or they will smother each other, leave gaps between them (‘No Man’s Land’). This provides space for inter-planting when perennials are dormant (snow drops for example flower in Jan/Feb) without impacting on sunlight needed by perennials. It also leaves space for larger bulbs like tulips or alliums or for weaving in self-sowers from other areas of the garden.
- Lay canes on the floor of beds to mark out areas dedicated to specific plants and the gaps between them, mock up a full size bed on a lawn to scale in order to get accurate estimates on required plant volumes per mini-bed.
- Foliage vs foliage; remember that it’s not all about flowers vs flowers, think about contrasting leaf shapes and patterns as well when choosing and placing plants. This goes for pots too; pots of greenery can be mixed with more traditional floral pots to provide an interesting dispay.
I am now thinking about my garden plans for late 2017; once I have completed the formal Italian garden that I’ve been constructing in our high garden, I shall need to plan an acid and shade loving long season bed for our front garden using the techniques that I have learned from Fergus.
