SGS cherry blossom

Well, we’ve had snow, sunshine and rain and with the time change this weekend it really is beginning to feel like spring. I’m enjoying the flashes of colourful bulbs in bloom everywhere I go with the scent of hyacinths heady in the air, the garden filled with birds chirping before dawn and the massive bumble bees defying gravity with their flying skills – it feels like spring.

With this change in seasons comes that irresistible urge to get back to the garden, long gone are the lazy afternoons with gardening books open for inspiration, now is the time to work.

I spent hours outside this past weekend fixing up the vegetable plot, assessing the state of the compost bins (I have four), trimming back errant rose branches and carefully clearing out the perennial border. I also had some time with my mulch. I love mulch – a curious statement perhaps but not when you realize what magic it works. I keep a large bin of leaf mould and once decayed, after at least a year, I spread it on beds in the garden which need an improved soil structure, perhaps areas where I’ve noticed the beds drying out in the summer. Leaf mould does not bring much in the way of nutritional value to the soil however it really does improve the structure. By adding a layer of at least 6cms to the earth, weed growth is discouraged, humidity is retained and the insects do all the work by working the leaf mould into the soil. I use well composted garden material as mulch in areas like the vegetable plot and perennial beds where I want to add nutritional value as well as improving the soil structure.

I planted a green manure of spinach this winter in two of my raised vegetable beds and this weekend turned them into the soil – I’ll wait another couple of weeks before I plant something in them. My herb bed is showing signs of life with the tarragon coming along nicely and the unstoppable chives reaching for the sky. I’ll be moving the beans into a new position this year and have just moved the structure that they will climb up from one bed to another – now all I have to do is choose a variety. We have had snow over the Easter break in the past so if you are thinking of sowing vegetable seeds directly now do consider buying some fleece to protect your young seedlings – better safe than sorry.

Wow! What an autumn we’ve enjoyed. The days, although shorter, have been filled with the most wonderful light – the trees have kept their leaves for the longest time and spoiled us with their rainbow of colour. I am a sucker for a good tree, once I find a good one I make it a point to drive past when I know it is at its peak. My children are tormented with the constant “ohhs” and “ahhs” and “look at that” from my position as driver. This month my favourite is the fabulous Gingko biloba, the Maidenhair tree (photo above) located in the park by the Musée du Léman on the lake front in Nyon. Although native to China this specimen tree grows very well in Europe. It is one of those beauties best grown in public places for all to enjoy as it can reach a height of 30ms. The leaves are fan-shaped and turn the most vibrant butter yellow at this time of year.

The only downside of trees keeping their leaves for such an extended period is that the leaf raking seems never to be done. As I’ve mentioned before rake up the leaves, bag them in black sacks with some air holes, keep them damp for at least a year or more and hey presto, magic leaf mould. Leaf mould is a brilliant mulch for the garden, keeping the weeds to a minimum and the moisture retained. Unlike garden compost it does not bring much nutrition to the garden, so best not to add it to the vegetable plot.

Well we’ve been on a roller coaster with the weather over the past few weeks. The Indian summer lasted beautifully through the end of September and with the arrival of October the temperatures dropped and the bise wind rose. The tomatoes hung on to the bitter end but it is all over, the green ones are now in the kitchen in the hope that they may turn red but I predict an afternoon of green chutney making in my future.

This time of year is always bittersweet for the gardener, the glory of the summer garden has come to an end, the perennials have all gone to seed and while the seed-heads look wonderful the colour is slowly disappearing before us. Dahlias continue to perform and until we have consecutive nights of freezing temperatures they will continue to shine. It is a time to think about the future of course because this is the perfect time to add plants to the garden, trees, shrubs, hedges and perennials can all be planted until the freezing temperatures arrive. Have you got plans for trees, adding perennials? Take advantage of dry days to get out and make plans and plant them up, it is never nice to garden in the rain.

I’ve been busy this week, harvesting all the beans, I’ll be drying them out, shelling and storing them for use in soups and stews over the winter. I aways cut the plants to the ground, throwing them onto the compost, and leave the roots alone until the spring, this allows the nitrogen nodules along the fine roots of the beans plants to augment the nitrogen in the soil. I then cover the bed with about a 10 cms layer of mulch and leave that to work its way into the soil over the winter. Home made compost makes for a great mulch but it should be well broken down and at least a year old. If you don’t have any ready to go there are a number of places locally where you can buy it by the “big-bag” or have it delivered. I’ve used BGS Compost SA in Givrins, although closed on Saturdays it opens from 07:00 Monday to Friday.

It is true that most of us who garden spend a fair amount of time discussing the weather; too hot; too dry; too windy; too wet; too wet; too wet. Well this summer we’ve certainly had a lot to discuss, with the incredibly wet and cool start in May and June to the tremendous heat of August – never a dull moment. Our gardens are so quickly affected by the changing weather conditions especially when it is holiday time and we are not on hand to adapt our habits day-by-day or week-by-week. In my experience it is always best to err on the side of caution and this is a perfect example of why. Early this summer I left half a dozen newly purchased perennial geraniums amongst a group of larger pots hoping they would be happy (and sheltered) enough during my week-long absence – I came home to crisp leaves and parched soil. I was so sad I immediately moved them to a more shady spot, drenched them with water and have been nursing them back to their original state ever since. Note to self, always pay a teenager to water even for a short trip.

The hydrangeas this summer have been just spectacular and although they need quite a lot of water, if they are in the correct position in the garden they will have given you quite the show. There has been a renaissance of the hydrangea in recent years with more and more varieties becoming easily available, this year I found a very pretty new (to me) variety called Hydrangea arborescens  “Incredible Pink”. As the name suggests it is pink but not the bright showy pink of my childhood. Each petal is delicately edged in pink giving an overall dusty pink colour (see photo above) – just gorgeous, now all I have to do is find a reasonably shady spot for it in my garden, no easy feat.

With the garden centres and DIY shops heaving with beautiful summer annual flowers, salad plug plants and vegetable plants it is understandable that you could be fooled into thinking that it is time to plant up the garden. But no, as the weather over the past few days has confirmed there is still time for snow and late frosts. When temperatures drop overnight to around zero significant damage may be done to immature and tender plants. Local advice dictates that nothing tender should be planted outside unprotected until after the days of the “ice saints”.  These ice saints, Saint Mamertus, Saint Pancras and Saint Servatius, celebrate their feast days on 11, 12 and 13 May each year. Each year of course differs from the last and often temperatures are accommodating and we have no issues with chilly nights but when we do we really do. With temperatures due to stay low cover your veggie beds with horticultural fleece and move your pots next to the house for a little protection.

I am frequently asked what do with bulbs when the flowering has finished. Firstly and most importantly enjoy the flowers, whether you leave them in the garden or cut them for the house. The next tip is to dead head all the daffodils, only trim the flowering stem, this prevents the plant from producing seed. Allow the leaves to turn yellow, and I’m afraid this is where patience is necessary, the longer you wait the greater the show next year. When the leaves are limp and yellowed only then it is time to cut them back. Daffodils do very well when left in beds or naturalized in the lawn, tulips are a little more temperamental. In public spaces the tulips are always dug up, and new ones planted later in the year, this is not terribly practical or economic in a private garden. To get the best repeat show with tulips make sure they are well planted by December, three times the depth of the bulb, make a note in your garden notebook as to where they are (you will forget); there is nothing worse than digging up bulbs inadvertently when they are dormant in order to plant something else. Ensure the area does not dry out over the summer and don’t forget to fertilize the space with a general purpose fertilizer later in the year when all signs of the tulips have disappeared.
