Thoughts on planting and weeding…

Verbena bonarienisis with Daucus carota, Tostat, July 2019

Forced inside by the massive heat last week, I took to reading about gardens rather than gardening. Also, I am in a reflective state about the garden at the moment as I am noticing the changes from having less ‘arm’ to do maintenance, and I am curious about how this will shape up over the summer. So, picking up Noel Kingsbury’s article about planting density, which I would ordinarily have saved for a rainy day, set me thinking. I won’t recount all the detail as you can pick this up via the link, but working backwards from his reasons as to why more dense planting makes sense made great sense to me. He posits three main reasons for dense planting:

  1. Denser planting reduces the need for weeding
  2. It increases biodiversity, providing more cover and food opportunities for essential garden wildlife
  3. More plants mean more biological activity which supports an effective ecosystem

So, possibly post-hoc rationalisation, but here is what I think is going on in ‘The Mix’ my perennials/grasses/shrub combination underneath the cherry tree at the back. A spot of analysis follows…

The Mix, Tostat, May 2019

This May photograph is a little late to qualify as Spring, but it will do. You can see the massive importance of the wafty Stipa tenuissima, the tall Allium nigrum coming through, and the pink of the Oenethora all work well together.

Just now, early July, those Alliums are still there as seedheads, but the whole look has gone up a gear in height and variation. Crocosmia ‘Lucifer’ is sparking red through the planting, and an annual tall daisy, with many small, white flowers, which self-seeded itself last year, and has really romped this year, has taken the eye up further, whilst the Phlomis longifolia var.bailanica is giving stature with seedheads, and the grey-silver of the Helichrysum rosmarinifolius ‘Silver Jubilee’ (now also seen as Ozothamnus) planted 2 years ago is poking through nicely.

In mid July, the whole scene will change as Monarda fistulosa, which has just begun to open, will ripple through the scene with warm pink long-lasting flowerheads and will compete as the daisy goes over to take over as the main theme. Later, Patrinia scabiosifolia will come in at early August with electric-yellow umbels shooting through leading to Solidago rugosa ‘Fireworks’ in September.

All that I have done is chosen some plants and threaded them between one another fairly closely, allowed a little room for self-seeders, and other than removing the odd dandelion or plantain, I have left it to sort itself out. What I have realised is that between me and it, we have built up a flow of plants that move into the foreground and change the dynamic as time passes- giving way to others as they go. Very little has needed to be removed, and the shrubby elements, the Phlomis bailanica, Berberis thunbergii ‘Maria’, Helichrysum rosmarinifolius ‘Silver Jubilee’ and Miscanthus ‘Gracillimus’ have created the beginnings of a permanent structure as a backdrop.

The other article that continues to set me thinking was Alys Fowler’s article last week on weeding. I always like her thoughtful articles, and this year weeding has taken a back seat in Tostat. I have been surprised at how little this has bothered me, and I have learnt that I have only to wait for plants to grow up and over, thus hiding the interlopers. Then summer heat will finish most of the rest off. I just need to stay calm for the month or so in the Spring when it looks as if all is lost. I am going to go easy again on weeding next year. I adore the combination of the Verbena bonariensis and the wild carrot, Daucus carota and will welcome that back. (see top)

Where I will not go easy is my eternal battle with bindweed. But, 3 years ago, I grew and planted out Tagetes minuta all over the garden where we were under siege from bindweed. Tagetes minuta seedlings have continued to work away since them, and we have a very different garden thanks to them. I have ordered more seed for next year to bulk up the population.

June goings-on…

Mix 0619

At this time of year, the light becomes so bright that photography is an early morning or late evening activity. The light creeps over the house in the morning like a ranging searchlight, and the other day, it was the right place and the right time.  Standing by the Mix, my now 3 year old perennial planting with the occasional small shrub and grass, the sun spotlit the tops of the clumps of perennials, picking out the Monarda fistulosa and the Lychnis chalcedonica ‘Salmonea’ as the tallest in town just yet.  This area has been a real experiment- made even more experimental this year by the one-armed bandit requirement of ‘no weeding’.  About 6 weeks ago, it looked pretty awful.  But now, with the rain and sun we have had, the perennials are powering upwards, and, unless you have a pair of binoculars, you mostly can’t see any serious weed activity.  There is a lesson here for the future.

Pap som 0619
Papaver somniferum, from Biddy Radford, Tostat, June 2019

This has been a good year for self-seeding- another bonus for one-armed gardening.  Opium poppies, Papaver somniferum, have popped themselves all over the gravel paths and into some of the more orthodox places as well. As self-seeders, you can get years when the colours are very washed out- but this year has been loads better with good mauves and soft pinks.  The bees and insects love them- and I do, for their unfurling architecture as much as for the flowers.

Penstemon Dark Tower 0619
Unfurling Opium poppy and Penstemon ‘Dark Towers’, Tostat, June 2019

Playing with Penstemons has become a bit of an obsession.  I grew some Penstemon digitalis ‘Husker Red’ from seed the year before last, and so with the wait, this is the beginning of seeing the plant in action.  Slim, upright growth, dark beetroot colouring on the stems and leaves, and buds which are creamy-yellow.  Not yet a big player, but with potential.  I also bought some Penstemon ‘Dark Towers’ a cross between ‘Husker Red’ and ‘Prairie Splendour’.  Now this is a big, beefy plant.  Strong upright, dark crimson, darker than ‘Husker Red’, stems and leaves, altogether bigger and more imposing, and then, on filigreed stems, big pale mauve flowers. So far, so very good.  Not yet tested for drought tolerance, but that will come.

Trifolium rubens 0519
Trifolium rubens, Tostat, June 2019

Two years ago, visiting the stunning gardens at Kentchurch Court, I was seriously smitten by what seemed like giant clover flowers on speed.  It was a variety of Trifolium, and so I have been growing some from seed since last summer, and it is just about to flower.  This is the species form of Trifolium ochroleucon– more to follow.  But, I have also bought plants of two more Trifoliums, Trifolium rubens and Trifolium pannonicum ‘White Tiara’.  Both are doing well so far in their first year, seeming to cope well with the conditions- the true test will come.

Philadelphus Starbright 2 0519
Philadelphus ‘Starbright’, Tostat, June 2019

A bargain basement buy this year in the new area, still covered in cardboard, and holding its own, is a newish variety of Philadelphus called ‘Starbright’.  A recent Canadian selection, it has dark-red stems and strong, single white flowers and is very cold and drought tolerant- hence my giving it a go.

Phlomis var bailanica 0519
Phlomis longifolia var. bailanica with Allium nigrum behind and a sprinkling of Dianthus cruentus, Tostat, June 2019

This has been the year of the Phlomis- all my plants have adored the weather and conditions.  Phlomis longifolia var.bailanica has doubled in size, and has emptied the custard tin over itself, with incredible Birds Custard coloured flower heads.  I am responsible only for the Phlomis and the Allium nigrum, also enjoying life- the Dianthus cruentus is self-seeded, I think from a few feet away.

Tomorrow, we are off to visit Jardin de la Poterie Hillen– this should be a lovely garden day with great patisserie as well.  Not to be knocked.  And some splendid planting, such as this extraordinary rose, Rosa ‘Pacific Dream’, photographed by my friend Martine in case I missed it….
