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.
