Garden Diary — Autumn 2025

The long hot summer continued into Autumn, with lots of sunny days between the much-needed rainfall. The garden gradually winding down… Many species — flora and fauna — contribute to a finale so long and sustained that the it was impossible to say when summer ended and autumn began. I made very few changes to the garden: Mostly just maintenance tasks, which I’m so accustomed to (and enjoy) that I barely notice them. The garden is mature now. It ticks over. Things change. Things die. Things appear, unexpectedly. Things get replaced. Little now threatens the overall dynamic balance. I’m glad I put time into sound structures: sheds, fences, paving. They mostly shrug off the seasons and need little attention to stay in good nick. The hedges, mature shrubs and trees hold everything together, even as the seasons turn inevitably and imperceptibly.

SEPTEMBER

Following the drought of summer, September brought some welcome rain, while continuing the glorious sunshine most days. I did little gardening beyond lawn mowing and weed pulling. My planting continues to provide new flowers and attract insects right into October, so there was plenty to enjoy and photograph. A good example is the planting above in my Pond Garden — a lovely colour combination courtesy of Euphorbia ‘Miners Merlot’, Sedum ‘Plum Dazzled’ (bottom-right), the geometric glaucous foliage of Euphorbia myrsinites (bottom-left), and September Plant of the Month, Aster × frikartii ‘Mönch’ (behind). These plants are hard workers in a planting design, with the euphorbias and sedums providing interest for 6-9 months or more, and the Aster flowering from July-October.

OCTOBER

This month, my main project was replacing two Hydrangea ‘Annabelle’ that flank the kitchen doors, with the very similar ‘Annabelle Improved’, that’s not supposed to flop in the rain. (You can read my long-term white hydrangeas review, here). Meanwhile, I’m reminded just how much is still happening in the October garden. On warm-bright days it feels more like summer than autumn, with insects and flowers everywhere: very active and delightful.

NOVEMBER

Autumn has been brilliant this year. The fruiting cherry that makes the canopy of my Woodland Garden at the front of my house was spectacular (See above). I spend time sweeping leaves, and tidying up the beds beneath, only to have more leaves dropped the next day! These woodland beds, once cleared of last year’s dead foliage, quickly become a thing of glory with Hellebores and snowdrops just round the corner.

Final thoughts… There are no frosts forecast in the lead up to the new year, so I can leave the agapanthus pots outside, which is good, as the leaves on the greenhouse peach still have not fallen. Once they do, I’ll need to find time to tidy them up before moving the African lilie pots under cover. As we move into December the mild weather holds off the feeling of winter, but the garden knows different: I expect to see Hellebores and the foliage of snowdrops emerging soon. So, until next time…

HAPPY CHRISTMAS!
