Pat’s 10 jobs for May 2025

1. Border irises are really doing their thing now and the show can be brief but make sure to keep the soil around their roots free of weeds so their rhizomes can bake a bit in the sun.

2. Time to Chelsea chop your tall perennials to stop them flopping later or to extend flowering. Good candidates are Phlox, Penstemon, Helianthus, Sedum/Hylotelephium – and I include vigorous Clematis too. You can either do the whole plant at once or just some stems to extend flowering, although it may result in smaller flowers.

3. Deadhead displays of pot plants like Violas to keep them flowering and stop them going to seed. Remember to give them a feed to keep the display going.

Pat’s Jobs for January 2025

1. Prune Wisteria this month and next by taking all side shoots back to 2 or 3 buds. Very old plants may need severe pruning to show off the flowers.

Very tangled wisteria waiting to be pruned — Very tangled Wisteria in need of pruning!

2. Start pruning roses in earnest although some are still unbelievably flowering. Remove any foliage with blackspot and don’t compost. Old roses respond well to hard pruning so don’t be afraid, removing all dead and dying wood and cutting stems back to above a bud.

3. I had to remove dead Clematis shoots from a Daphne Jacqueline Postill and in doing so pulled off some of the flowers so take care and do it soon if you can. But leave the main prune until next month.

The Exchange, Walnut Tree Road, Erith

One autumn Saturday morning in 2024 my companion and I visited the Sarah Price-designed garden at The Exchange in Erith, South-East London and we were in for a treat.

As Erith Library for over 100 years, and Grade II-listed, this Carnegie-financed building of 1906 finally closed its doors in 2009, thus becoming an unused space with unkept grounds. Two visionary locals, respectively with conservation and community arts experience, approached Bexley Council in 2016. Their initiative resulted in a community arts hub which opened in 2022 – a refurbished building with a new garden to match.

The garden surrounds the building on all sides, with various plantings complementing each of the four different areas. The forefront of the building has become a Mediterranean garden with a tapestry of lime-greens, blue-greens and greys. In amongst the herbaceous and shrubs I noticed Myrtle, Euphorbias, Irises, California poppies and particular favourites, sub-shrub Dorycnium hirsutum and several Hesperaloe parviflora (red yucca), a very choice succulent that I have at home (and managed to keep alive!). On our visit we noticed that flowering was just finishing, with its tall stem of red-orange pendulum flowers just going over.

Pat’s Jobs for November 2024

1. Check for blackspot on roses and make sure to remove the leaves by checking the bush itself and below it. But don’t add to the compost heap.

2. If you have to, this is the best time to move trees and shrubs, but have your planting hole ready, and dig up with all the root ball and replant quickly, watering well until settled.

3. Plant your tulips and hyacinths now. either in the ground or in pots – but protect from squirrels.

4. If you sowed sweet peas last month. harden them off now and it’s still not too late to get some going for an early crop.

Pat’s Jobs for August 2024

1. It is especially important to keep Camellias and Rhododendrons damp at the roots this month as this is the time that the buds form for next Spring. Water well and mulch if you can.

2. Take Aeonium cuttings now by severing leggy leaf stems a couple of inches below a cluster. Leave the stem end to callous over, then push into gritty compost and keep in a shady spot until roots start to form.

June 2024 Meeting and Talk: Hever Castle and Gardens

A successful meeting was held in June with a packed audience and we were lucky to be given an engaging and informative talk by Neil Miller, Head Gardener at Hever Castle. In 2002 Neil started as a junior gardener at Hever following 10 years as an Insurance Broker and within 4 years was Head Gardener. Quite an achievement!

Famously Hever Castle was the childhood home of Anne Boleyn, and Henry VIII frequently visited her there. At that time the surrounding land was marsh and bog land. Though there were many changes of ownership in the following centuries, it was not until 1903, when William Waldorf Astor bought the estate, that serious restoration and renovation took place and the design for the gardens was drawn up. Alongside the castle, a Tudor style Village was also built so that invited guests had rooms to stay.

Plant of the Month: Rose (June 2024)

June really is the month for roses and when I saw Margaret T’s roses growing on her allotment, I was enchanted by each and every one and I have listed below a few that are in flower now.

Rosa 'James Galway' — Rosa ‘James Galway’

A David Austin climbing rose, introduced in the year 2000 and named after the Irish flautist. Margaret grows this rose as a shrub, so the flowers are at head height and the pink blooms, paler at the edges, have an old rose appearance and fragrance.

Rosa 'A Whiter Shade of Pale' — Rosa ‘A Whiter Shade of Pale’

What a name! And, what a rose! This gorgeous hybrid tea has blush-pink, very fragrant, repeat-flowering clusters, and glossy dark-green leaves. Considered disease resistant. Introduced in 2006 by rose-breeder, Colin Pearce.

Pat’s 10 Jobs for February…

1. Prune Group 3 clematis (late flowering viticella types) now by cutting all stems back just above a leaf node starting from the ground up. Don’t be timid as they respond well. Then feed around the plant base with an organic feed making sure to avoid emerging shoots and mulch with compost.

2. If you have some, mulch your beds with homemade compost or leafmould. If you don’t have enough just mulch around your favourite plants.

The View from my Window

Vija and Anna started these great posts about the view from their windows, and I thought I would add my bit. Really, in these cold, grey days of winter, it’s a bit odd that I should find the view from my window at all exciting. We have big patio windows which are unforgiving at this time of year and expose everything in the garden: the ragged border edges, uneven lawn, leaning obelisk (Storm Henk!) etc. But I can sit in my comfy chair looking out and now the leaves are all gone I can see all the way to the end fence..

…and I can Plan.

When I say I can see the end fence, this is because we took out a row of 20 ft high Leylandii trees last October. (Did we buy the house with them, I hear you ask? No, I actually planted them, one of those teeny gardening mistakes surely anyone can make..?) The idea behind getting rid of them is that it will let lots of light in, when next we have any. The stumps have been left, as I couldn’t face a stump grinder trolling through the house, so I need to Plan some sort of feature around them. (Maybe a birdbath on top of one..!)

A bonus is that for years and years I had been piling leaves and cuttings out of the way under the trees – so I am now left with some truly gorgeous compost! A little silver lining.

February 2023 Talk: A Garden Reborn

Ruth Cornett, the owner of the Eltham Gatehouse situated adjacent to the historic Eltham Palace and part of its history, gave an excellent and informative account of how she has renovated the Gatehouse garden which along with the house was neglected and semi-derelict when she and her husband bought it in 1998. Having previously lived in a North London flat and from a rural Irish background, she was desperate to have a house and garden and set about renovating and restoring the garden in 2015. Ruth showed us pictures of before and after.

Eltham Palace is a medieval house with a long history. At one time a Bishop’s Palace and a Tudor hunting lodge, it was bought by members of the American Courtauld family in 1933. They renovated the Palace and added an Art Deco extension, then handing it over to the Royal Army Educational Corps in 1945. Its head resided in the Gatehouse. When the army left in 1992 the Gatehouse was left empty and the garden was abandoned.
