September garden musings

DSC_0015 (2)

If you happened to drop by and you enjoy looking at pictures of my garden – welcome!

But be aware that this post is mostly for the benefit of my absent husband who likes to keep up with what’s happening – it may be too long for you! Also – although I love garden memes, I sometimes find them really exhausting. When I first started blogging, I did it because I wanted to record some of my own garden experiences. To be honest, I wasn’t too bothered if nobody else read what I wrote. The memes have taken some of the pleasure out of that experience … added to which my eyes are not taking kindly to the hours in front of the computer demanded if you truly try to ‘keep up’ and be a good blogging friend.  So these are just ramblings. And I’m giving myself permission to do more!

Here’s your parched garden, Nick. Still no rain to speak of and temperatures have climbed a little again into the low 30s. We are forecast a little rain tomorrow after 12 days – but it often passes us by. And then there seem to be no dark clouds for days to come. Hey ho …

The supper terrace has been the most luscious place this summer, the foliage so huge, the blooms of hydrangea so welcome (must get more) when it’s hot. This just proves what watering can do.

DSC_0014 (2)

And the orchids do seem to be enjoying the trick of hanging outside with a regular spray over. I really enjoy them, because they look more like the orchids I remember from my botanic garden days.

DSC_0012 (2)

As epiphytes they relish that regular touch of cool and damp. Unfortunately I haven’t got it automated and so I have to run down (or up!) regularly with my little hand sprayer. But they are looking cool and much happier. The idea is that they are whisked into the house in flower.

DSC_0013 (2)

On the Mirror Garden we have a desert aspect. The only things left in the lawn are the Verbascum thapsus that grow everywhere in Chatillon. They have to have their heads chopped regularly.

DSC_0018 (2)

I had to cut back the Banksian rose (Rosa banksiae ‘Lutea’) hard in July, mainly to dispose of Muelenbeckia complexa. It looked so sweet in that little pot – and remember how I gave out when you accidentally strimmed it Nick? But it’s a horror, and I do wish I’d read how invasive it is before planting it. Below are before pictures …

DSC_0231 (2)DSC_0169 (2)

It was growing in all the crevices of the old tower which is part of the medieval ramparts. I was fearful for the stone. I’ve sprayed it twice with weedkiller since rooting it out, but it will need more and I noticed yesterday that a tuft in the wall is greening up again.

And some ‘after’ pictures …

DSC_0006 (2)DSC_0007 (2)

You can see how much pruning I had to throw down to the next terrace (and then throw down to the next – my disposal method for woody prunings). You can also see that I accidentally broke the downpipe from the roof! Even that rusty old thing had Muehlenbeckia growing in it!

Fortunately the rose is coming back after the massacre, although we won’t have much flower for next year.

DSC_0021 (2)DSC_0020 (2)

Following attacks by the box tree moth caterpillar (Pyrole de buis) I sprayed twice with Bacillus thuringiensis (May and late July) and set three pheromone traps (which caught a lot of adult moths). My box is still alive and, if not thriving, still providing the structural element I like.

DSC_0019 (2)

Back in May I did clip all the garden box at the same time when I first discovered the caterpillar (I usually do it in stages). And that removed tonnes of the little blighters, so quite an important step! It took me about 3 days, with 3-hour stints each day. The actual spraying takes about 2.5 hours to cover everything in the garden. It’s debatable if this process is for everyone.

I still like to think the box tree moth can be controlled. It was so bad this year – decimating everyone’s box for miles around – but I think that may have been due to the fact that no one in the area paid much attention to the first onslaught in 2017, myself included. Next year I am also going to try a French nurseryman’s recommendation that box be clipped in late February – he says this can remove any ‘problems’ that are over-wintering in the top growth.

The Vine Terrace is looking sweetly autumnal – although the birds and wasps have had the grapes as usual. Next year, maybe? We need to be bottling our own wine in this house!

DSC_0016 (2)

The greenhouse still has some tomatoes coming on, although it’s all slowing down now.

DSC_0035 (2)DSC_0033 (2)

Outside I’ve been really enjoying the Salvia ‘Mystic Spires’ and white antirrhinums that were planted in the two new pots you bought me, Nick. They look good with the Ricinus communis that were never planted out in the Long Border due to the early heat. And what I think are carpenter bees (comments anyone?) are enjoying them too. These big black bees come in the morning (perhaps nesting in the rampart walls?) and are replaced by honey bees in the afternoon. Curious.

I’m so glad that Eryngium ‘Mrs Willmott’s Ghost’ is seeding and spreading in the Rose Walk.

DSC_0038 (2).JPG

Biennials and annuals that like to self-seed here are to be treasured because the heavy clay is not for everyone. So far we have Salvia sclarea, Papaver rhoes, P. somniferum and Verbascum thapsus that seem to like us. I notice that all of these like heat and have quite fleshy taproots (with the exception of the annual poppy). For the life of me I can’t establish Dame’s Violet (Hesperis matronalis) or Honesty (Lunaria annua) or Forget-me-not (Mysotis) although I keep on trying, and perhaps they will do better below where there’s more space for self-seeders.

The veg plot is a DISASTER!

DSC_0026 (2)

I am still waiting for my brassicas to recover (they usually do in September, but we haven’t had the rain and cool they like). The pumpkins did quite well, but surprisingly little fruit, and the french beans didn’t get enough water after my first great pickings, so petered out quickly. On the other hand, the autumn-sown broad beans were great and I still have perpetual spinach and chard to pick (chard running up to seed slightly), since they can take a bit of heat.

DSC_0043 (2)

The Long Border looks pretty messy and dry, but that always spurs you on to plan constructive changes for the following year. There are many shrubs due to be replanted down below and I’m sick of the vast swathes of hemerocallis that I inherited with the garden. It’s a pretty boring plant, in my opinion. But it does love it here and perhaps I should experiment with different, prettier, colours than the standard orange.

DSC_0042 (2)

Still roses flowering. ‘Jude the Obscure’ hasn’t been too bad this year, after slowly moving into gear for the last two seasons.

DSC_0056 (2)

A friend has a ‘Tess of the d’Urbervilles’, consumed by what I think is brown canker. David Austin should think twice before naming roses after tragic heroes and heroines. But I think Jude will win out, unlike his namesake.

This is the first year that the Reverend Pemberton’s Hybrid Musk rose ‘Felicia’ has risen to her full height.

DSC_0054 (2)

There are one or two interesting perennials still flowering (many of my flowers were over far too soon in the Long Border this year, although fortunately it looked good in May and until the end of June when the garden was open). Aster ‘Monch’ is always nice …

DSC_0048 (2)

Funnily enough the other asters (michaelmas) haven’t really got into their stride yet. One helenium remains in flower. My least favourite called ‘Loysden Wieke’. I should take it back to the nursery, because they swore I’d love its quirkiness …

DSC_0050 (2)

The Hornbeam Gardens are still taking shape from what used to be their field – with the expected weeding (especially of crab grass) that comes with the transformation.

DSC_0045 (2)

I’ve managed to clip the hedge in the top half, which is the cut flower garden. You can see my ladder working on the arch …

DSC_0046 (2)

But the hedge at the bottom remains hairy and wild. The bottom is also proving a bit of a problem because it is incredibly dry down there, owing to heat and the greedy roots of an ash tree just beyond our boundary. No matter how big your garden, this is a problem that you always seem to encounter. But maybe I should rejoice that the ash is not yet dead, as it is in Britain?

Finally – the little cyclamen, many of which came from your mother’s garden in County Wicklow, Nick, are still alive and starting to bloom really well. A terrible picture, but in the life they are more than whispy ghosts! Hopefully they will still be on the go when you are back at the end of September!

DSC_0057

This summer has given many of us pause for thought. We do not all love gardens that are ‘bedded out’ every year, and some of us feel immoral when we over-use the hosepipe. I water my spaces no more than once a week. In the past this has worked, but this year when I look at the pots that are watered every day and the borders that are rationed I can note a huge difference in growth.

I do not feed borders either, because I believe this just plays into the hands of the big businesses that want to take my precious pennies. And I prefer a natural style of gardening. Instead I use a little slow release, organic fertiliser on roses and I hope that mulching with the product of my new compost bins and the material that runs through the recently purchased shredder will give the soil back what it needs.

I refuse competition. My garden is for our pleasure, not to make somebody I’ve never met a lot of money or to impress my neighbours. But it’s difficult when you encounter climate change as we are doing at the moment. Ideally I’d have a low maintenance Mediterranean-style planting here, with lots of greys and drought-tolerant plants. That’s also why I’m so interested in things that like to self-sow. But the soil does militate against this style of planting. It is cold and very wet in the winter and dry as – well, fired clay, in the summer!

My new year resolution (did you know that September is traditionally thought to be the start of a new gardening year?) is to try and evolve a planting style that is appropriate for this place and not so based on the traditional English herbaceous style that I ‘grew up’ with. So lots of lists – and lots of seed to purchase! I do think grasses and bulbs will figure large, with early-flowering perennials, because the late-comers can’t take the heat. Just wish I could add succulents and dramatic shapes to the Long Border, but it will be way too cold for them here. Could be fun, if and when I rise to the challenge!

A few favourites … daffodils and tulips

 

DSC_0047 (2)

So there I was this morning – all chirpy and free like the birds, with a day to spend in the garden. All is going so well down there – things shooting that I never expected to see again, plants establishing nicely with the warmth and a drop of rain.

DSC_0101 (2)

Lots of things ticked off my open days ‘to do’ list – forget about clipping the box, visitors will have to experience it wild and woolly! (I got nervous about clipping it because tightly clipped box is more susceptible to box blight. Little did I know that was the least of my worries!)

DSC_0163 (2) APRIL

DSC_0139 (2)

Cheerfully I went down, weeding bucket in hand, to attend to revamping my delphinium and aster border in the cut flower garden.

DSC_0066 (2)

That was then, and this is now, with me sitting in front of the computer on a still bright April evening. Not my style. How did that happen?

I’ll explain later – first I want to record (as much for my own sake as anything) a few of my ‘favourite things’ over the last four weeks. (Note to self: blog more frequently … and more briefly!)

I haven’t many different daffodils in the garden, but I do treasure the ones I have. First to flower is always the Bon Viveur’s ‘Jet Fire’.

DSC_0002 (2)

He develops obsessions with particular plants (two peas in a pod?) and so in it went, first in 2014, and another 10 in 2017.

Then there are the Jennys – ‘Jenny’ and ‘Peeping Jenny’. ‘Peeping Jenny’ starts before ‘Jenny’, in March. Gazing up in search of something … it is all that a daffodil should be.

DSC_0049 (2)

‘Jenny’ is my favourite, much shyer and with a paler trumpet. A little confused, with all the little heads looking in different directions. Where is danger coming from? Is it the voles today?

DSC_0021 (3)DSC_0180 (2)

‘Mount Hood’ was a new addition this year, although I’ve grown it in the past when it just kept on giving and increasing. The Bon Viveur bought the bulbs when he was in Ireland last summer – they came from our previous home in West Cork (where we never grew it!). If you like white daffodils, definitely give this one a go.

 

 

Narcissus ‘Actaea’ is amongst the last of the narcissus to flower – with a delicious scent.

DSC_0023 (3)

‘Actaea’ is followed by Narcissus poeticus ‘Recurvus’, the wild poet’s narcissus. It comes into flower at least a week later and is still going strong here, down in the wilder shrub area I’m trying to create in the Hornbeam Gardens.

DSC_0068 (2)

This area is a bit like me … it photographs poorly!

DSC_0092 (2)

Another new addition (which I don’t recall flowering last year, although it was planted in Autumn 2016) is ‘Goose Green’. Also in this Narcissus poeticus group,  I love it for the pronounced green inside the little coronet. But I’m a sucker for green in flowers.

 

 

And the tulips – ahhh … will I ever get enough of them?

The first, flowering from about 8 April,  was ‘Sweet Impression’ in the Rose Walk.

DSC_0010 (3)DSC_0015 (2)

There were three little species tulips in the Rose Walk as well. A dainty little Lady tulip, Tulipa clusiana, called ‘Cynthia’ …

DSC_0222 (2)

Tulipa tarda

DSC_0214 (2)

And Tulipa batalinii ‘Bronze Charm’, which was still flowering this morning.

DSC_0012 (2)

Tulipa  saxatilis  ‘Lilac Wonder’ was on the go in the Hornbeam Gardens just before before Narcissus poeticus ‘Recurvus’ started into bloom. When I first planted them in 2016 I had only leaves – this year some flowers!

DSC_0234 (2)

I always eagerly await ‘Queen of the Night’ and ‘China Pink’ in the Rose Walk. These were planted because they persisted in a previous garden. However, after much thought, I’ve decided that the persistence of a tulip depends on the soil: that previous garden was on clay too – but not as heavy and the garden not as hot as at Chatillon. The Queen and ‘China Pink’ have to be topped up every year in this garden if I want a decent show. The message seems to be that just because a tulip is persistent for someone else doesn’t mean it will work in your garden!

DSC_0008 (2)

DSC_0030 (2)

‘China Pink’ in the background, with ‘Sorbet’ in the foreground.

On the other hand ‘Sorbet’, which hasn’t been planted since 2015, comes back in fairly satisfying numbers each year. It’s a very nice surprise, indeed, when it arrives.

DSC_0029 (2)DSC_0015 (2)21 April

This is what I love about the Rose Walk at this time of year. I have been equally entranced by stitchwort growing in long grass on road verges – I could look for hours. It’s the allium buds that have me spellbound here.

DSC_0015 (2)DSC_0009 (2)

I have some rather good ‘West Point’ and ‘Flaming Spring Green’ in the Long Border, which reappear and have done so since planting in autumn 2013 – and I don’t think their number has ever dwindled.

DSC_0119 (2)

As planned, I took the ‘Ballerina’ and ‘Aladdin’ (which I had in the Knot Garden in 2017) down to the Long Border this year and they’ve been quite a treat, especially as I managed to plant Euphorbia polychroma (an old favourite of mine for the spring contrast it makes to tulips) last spring. I really love this plant – it’s as delightful in the same way as that old trouper, Alchemilla mollis.

‘Ballerina’

‘Aladdin’ just going over, with Euphorbia polychroma.

In pots I’ve also been enjoying a NOT ‘Queen of the Night’ on the Mirror Garden in my blue pots. It’s really charming, but definitely not what I wanted. Any ideas?

DSC_0044 (2)DSC_0131 (2)

And on the supper terrace are two pots full of dear little cheapies from Lidl – ‘Greenland’. I adore the Viridiflora tulips. Again that passion for green in flowers …

DSC_0102 (2)

And so – in the Knot Garden this morning I met my nemesis (for the next year or so, I reckon). I was admiring the individual charms of purple-black ‘Paul Scherer’ …

DSC_0055 (1)DSC_0048 (2)

teamed with the fringed violet of ‘Blue Heron’ …

DSC_0062 (2)

… while swearing also that such a dark tulip as ‘Paul Sherer’ should never be planted in the centre of the knot again – it disappears – and regretting the fact that pale yellow ‘Cistula’ hadn’t shown up at all (I’ve never complained to a bulb merchant before, but there’s always a first time).

And then I noticed some suspicious webbing on the box plants. Yes, it’s here – box tree moth caterpillar. In fact I suspect that it was lurking last year, but I was in denial at that stage because 2017 saw me in a bit of a Greta Garbo phase!

DSC_0198 (2)

I have now trawled over the entire garden and it is everywhere – not a single hedge or plant is untouched (and I have a few hedges).

XenTari has been ordered, and sprayer from Amazon (XenTari is a Bacillus thuringiensis biological control which gets a good press). All arriving Saturday. But I fear the fight to save the box will prove too costly, both in time and money. In my head I’m already planning their replacements. I think lavender would be nice for all the terrace edges where we have box at present. But what about my sweet little dumplings in the Mirror Garden?

DSC_0212 (2)

Ilex crenata might look to be a good idea, but I don’t think holly is very happy on our heavy soil. And apparently the only other plant that box moth likes is euonymus … so my back-up plan to replace box with Euonymus japonicus ‘Microphyllus’ is out of the question.

I’ll be afraid to go out into the garden tomorrow morning – will all the box be dead already? Will I spend another 2 hours (as I did today) hand-picking the little blighters?

At times like this you have to go a bit Scarlett O’Hara don’t you?

Otherwise you’d be as sombre (and not as beautiful) as a black tulip.
