grapes 2018b

By Tara Lissner, Swiss Gardening School

Harvest is a time of new beginnings, as the long hot summer draws to a close, the hum of traffic increases as schools return to their academic routines and the garden gives its final push of colour and splendor before the weather changes and autumn is really upon us. We have had the most spectacular summer season. The Swiss federal office of meteorology has declared 2018 the third hottest summer since records began in 1864; only 2003 and 2015 were warmer. Rainfall this year has also been record breaking, noticable by its absence, between 20-30% below average. These extreme weather conditions affect the home gardener making planting decisions more and more critical. Right plant right place the byword of Beth Chatto, the well-known British plantswoman, is now more important than ever.

How have you coped with these tricky conditions this summer? My lawn is once again dry and yellow with the soil beneath parched and dusty. I thought the pots on my terrace were large enough to cope with dry conditions but they have proven to not be big enough, note to self even larger pots for next year. Leaves are turning and falling from the trees at a surprising rate much earlier than I’m used to. The fruit on my trees are already mature which caught me a little off guard. Always adapting to changing conditions, there is never a dull moment.

On a more positive note, the roses have been truly magnificent, repeat blooming varieties giving their all for the entire summer – I don’t know how a garden can be complete without a rose. Returning from a trip a few years ago to find courgettes the size of a small dog, I refrained from planting them this year however we have enjoyed weeks of delicious fragrant cherry tomatoes with basil and more green beans than I know what to do with. My direct vegetable seed sowing efforts were less successful. I think the super hot conditions combined with sporadic watering just sunk them. Next year I’ll give in and spend time filling fiddly seed trays with compost and transplant out seedlings when they are robust enough to survive. Something I have not missed this year is slugs. For once the heat seems to have significantly impacted their numbers, let’s hope this means going into autumn there will be even fewer of these pests around to damage our plants. The box wood caterpillar however is never far off and I’ve ended up spraying against this pest already twice this summer. I keep a keen eye out for small white moths, I occasionally spray a jet of water from the hose through the small hedges to see if there are any to disturb. If I find some flying away I next take a closer look for caterpillars and their webbed cocoons. As I’ve mentioned before the best product on the market at the moment is Delfin by Andermatt Biogarten. This product is a drench which must be sprayed onto the shrubs in two parts, two to three weeks apart. Please think carefully before you plant box, while adding structure and form to the garden it now also brings significant maintenance.

tara april 2018

Wow! What a few weeks it has been. Gloriously warm temperatures, big blue skies, t-shirts and sun hats, winter a lifetime away – spring has really arrived, even though it feels like it could be summer. In Switzerland it this year it has been the warmest April for years and years, lucky us no? Or, perhaps not.

I’ve been having an amusing conversation with an Australian friend at the moment, I recently lamented that last weekend was just too hot for gardening (for me that is) and she just laughed and laughed, heat, she suggested, is what it feels like in the Australian desert! It is what we are used to I suppose but for me gardening a few weeks after Easter in 25c is just a little dramatic. I’d much rather a gentle increase in temperatures and enough time for me to acclimatize to the change in the weather. If nothing else this dramatic jump in “heat” leads me to think about the plants. There is a great gardening rule which is “right plant, right place” which means that every plant is a great plant so long as it is placed in its ideal spot, shade for shade loving, sunny for sun loving etc. Baking on my south-facing terrace this week has led me to think that I will give up on the lovely arrangement of cute little pots I’ve had there for the winter and only keep a few of the big ones. I promise to only plant heat tolerant, sun-loving beauties and shall retire the delicate plants and pretty small pots to the shed (sorry, cave) for the summer.

There is a softening underfoot, a warmth in the air and dare I say that feeling of spring abounds! It’s true we’ve been fooled before; a lovely gentle week in February followed by lots of snow and a wind chill that felt like -16c. But it will come, that light in the day, that stretch in the evening and that warmth in the air that means below zero temperatures are just a memory.

I do so love the optimism of March. Every DIY catalogue that comes through the letter box is packed with the promise of spring with bunnies and daffodils in almost every picture; lawn mowers and garden tools to make every job a breeze. Furniture catalogues encourage us to enjoy outdoor living with new patio furniture, parasols, coffee tables and sofas, to plan dinners and parties with friends. We the gardeners know that this is all just a sales tactic for it is far too early to even begin thinking about outdoor living, we are all preoccupied with outdoor working; beds to dig, mulch to spread, plants to grow, shrubs to prune and seeds to sow.

This perfect light, golden tones all around and cooler temperatures gently ease us into this new season of Autumn. The summer bedding is fading but trying to hang on continuing to perform in the sunshine, the summer veggie plot is almost at an end with the soft herbs going to seed and the green tomatoes fooling us into thinking that they may ripen on the vine (they will not), the lawn is showing signs of worm casings and a scattering of colourful leaves greets us ever morning – a time of change.

It has to be said that this summer was really fantastic, long days of warm sunshine, almost enough rain to keep the lawn green and that perfect blue sky. A hot summer like this reminds me to take a closer look at my garden. It brings to the forefront the areas I will need to concentrate on when the guests have departed and the rosé is finished. And so the list begins; add even more mulch to keep greater moisture in the beds, explore even more fully hardy but drought resistant perennials to reduce watering, reconsider the choice of planting for the vegetable plot when a holiday is planned – goodness I’m beginning to see a pattern, all of these issues revolve around water, the lack of rain and the need to irrigate. This may have something perhaps everything to do with the fact that I have a south facing garden on a hill with clay soil. Oh the work!

I guess it is fair to say that the April drought is behind us – so much rain! Not that we didn’t want or need it of course just not all in the same week. To keep us on our toes the ice saints “saint glace” have also been busy working their magic with really chilly overnight temperatures frosting the new growth on everything from grape and fruit tree crops to eager gardeners with their tomatoes and basil already planted. Local advice from everyone, including the nice lady in the queue at Landi this week, dictates that nothing tender should be planted outside unprotected until after the days of the ice saints These ice saintsSaint Mamertus, Saint Pancras and Saint Servatius, celebrate their feast days on 11, 12 and 13 May each year. This past week I saw early morning commuter cars covered in snow heading towards the autoroute – I remind you we are in May – keep an eye on the forecast and cover up your seedlings and tender summer bedding with horticultural fleece on nights when the forecast is for colder temperatures. The fleece should be removed in the day to harden off the seedlings and tender plants so they become accustomed to the temperatures.

With the arrival of May the plant market season is quickly upon us. From the small village “marché des plantes” to the bells and whistles of the wonderful “Jardins en Fête” this weekend in Coppet now is the time to get out and about and see what is on offer this year. Keep your eyes peeled for small posters advertising local plant markets, often short on notice they enliven village squares on a Saturday morning at the beginning of the season, Versoix, Trélex and Mies all are regular locations. The town greenhouses of Divonne will be open to the public on Saturday morning 20 May 09:00-12:00. Get a behind the scenes tour of the work that goes into making Divonne such a beautifully floral town. Click Divonne for more information.

I’ve been busy in my vegetable garden dodging the torrential rain. The beans and beanpoles are in, the potatoes are almost ready to be earthed up, the strawberries are flowering and will soon need their fruit lifted from the soil with straw, the raspberries are mulched and I’m waiting to buy my tomato plants at Coppet this weekend. I fear with all of this rain the slugs will be back in force very soon. The most effective way to deal with slugs is to use a nematode drench; a powder-like substance containing tiny nematodes which is mixed with water and applied to the soil, once in the slug the nematode releases a bacteria into the hosts which kills them. An effective product on the swiss market is made by Andermatt Biocontrol and is called bioslug. If you can’t wait to order by all means use whatever system works for you.

On to more pleasant subjects. I’ve been very happy to see my wildflower meadow is coming gently back to life, not least because our puppy decided to dig a trench through the middle of it. As it is on a slope I hadn’t noticed the damage until it was too late – a repair job of refilling the trench has now been completed and the area concerned reseeded, needless to say puppy is being more closely supervised in the garden.

Things are really taking off in the perennial borders. Peonies with their tight buds eager for the sun to reappear to help them open, the delphiniums are reaching for the sky ready to impress. While you still can still get into your borders give some support to your perennials, with days of rain and wind the new stems can be damaged and may well snap. Wire stands and supports are ideal, bamboo and string also works very well. It is best to do this staking before the plants get too big especially if you are using a cage, I’ve recently wrapped a delphinium in newspaper, secured with tape and carefully placed a tall wire cage over it, pushing the cage into the soil and then very gently removing the newspaper. The delphinium survived.

The good news about lots of rain is that the weeds come easily out of the ground. The bad news about lots of rain is that there are now lots of weeds! I’ll be busy this weekend pulling weeds and buying plants at Coppet. Enjoy the weekend and perhaps I’ll see you there.
