Song for Jasmine

Is your garden green? Well of course it’s green, it’s got plants in it, that’s not what I mean. How environmentally-friendly is it? Are there things we can we do to make it more friendly, yet still have a good-looking garden?

That’s actually a rather complex question. A garden is a place where we meet nature face to face, where we try to grow things and so does nature. Nature has had a lot of practice at this, and for us to impose our will may take some considerable effort. Alternatively, we could give nature a helping hand, working with it, instead of against it. That way, we can have a beautiful garden which is good for the environment, and which may even take less effort to maintain than we would otherwise expend.

We maintain our gardens with lawn-mowers, hedge-trimmers, fertilisers, herbicides and pesticides. Machinery requires energy (electricity or petrol) to run, and the chemicals we use have to be refined, bottled, and shipped to us. Herbicides and pesticides are obviously not environmentally friendly, they’re designed to kill things after all. Many of them are also harmful to humans, so careless use can have serious consequences for you or your neighbours.

We might think that fertilisers can’t be bad for the environment, after all, they’re supposed to make things grow. But many fertilisers rely on minerals mined somewhere in the world being processed and transported during their manufacture, much like many of the things we buy these days. Fertilisers that wash off the land and into rivers and lakes can upset those ecosystems by causing excess growth of algae, which can in turn kill fish and other aquatic animals. So even fertilisers come with an environmental cost.

So, if we could use less machinery and less chemicals, that would be a great start to making our garden ‘greener’, and save us some money in the process. That’s easy to say, but how, then, do we control weeds and pests?

One easy way to keep weeds under control is with a plastic ground-sheet. This is a sheet that covers the ground, you cut holes in it to plant the things you want. The sheet prevents weeds from growing, and your plants have no competition. You may have seen them at the side of motorways, where they are often used. If your plants are low and spreading, they will soon hide the sheet from view. Otherwise, you can cover the sheet with bark or gravel to hide it.

Another good way to control weeds is with mulch. Mulching means putting garden waste onto the surface of the soil. There it forms a dense mat as it decays, which helps protect the soil from drying out and makes it hard for weeds to grow. Grass-cuttings are ideal for mulch, but you can also use autumn leaves, straw, vegetable peelings from the kitchen, or anything that will pack down densely over time. Mulching also feeds the soil, as the mulch decays and releases its nutrients, just like it would in a compost heap. If you use enough mulch on your garden, you may never need to add fertiliser to your plants, the mulch will provide everything they need. That’s easier (and less smelly) than managing a real compost heap!

Alternatively, if you choose your plants carefully you can get the same effect from the plants themselves. There are many low-growing, fast-spreading plants that are very effective at preventing weeds from getting established. If you have only a small area to cover, hardy alpines will do the job nicely. Your local garden centre can help you choose some that are good for your situation. Once they have covered the ground they need very little maintenance. Plants which are taller than the cover-plants will not be affected, so you can have your roses growing quite happily surrounded by living weed-control.

You can also use plants such as clover and alfalfa, which serve double-duty as green manures. This means that they actually enrich the soil as they grow, so you will need less fertiliser to encourage your plants. Either grow them all year round, or just scatter the seeds on the ground towards the end of summer and let them grow through the winter, then dig them in in spring when you prepare to plant for the coming summer.

So much for the weeds, what about the pests, such as slugs, snails, and insects? Here the best answer is, more insects! And birds, frogs, lizards, and hedgehogs. In other words, the more wildlife you can attract to your garden, the less chance the pests will have to take over your plants. Pests multiply rapidly when they are safe from predators, so if your garden is teeming with wildlife, there will always be something to keep them under control.

Actually, that’s one reason why pesticides are a bad idea. They kill all species of insect, not just the ones you want them to. But the ones we want to kill will bounce back first, and multiply rapidly. That’s because they have no competition for their food (i.e. your plants) and nothing to keep them in check.

Birds are very easy to attract, just keep putting out food for them. They will still take the insects from your plants, especially in the breeding season, because they feed them to their young. Raising chicks is hard work for the parents, so if they can get a quick snack from your bird feeders and then find a juicy fat caterpillar for their young all in one place, they will appreciate it. We’re not the only ones to appreciate one-stop shopping. If you put up some nest boxes too, you can have resident pest-control working for you, all day long.

Frogs and hedgehogs will eat slugs, and they and lizards eat insects, so they can also be very beneficial to your garden. You don’t need a pond to attract frogs, they will be happy with any permanently damp and overgrown area. A shaded spot covered in weeds might well do the job. They can travel quite a distance too, so you may find them even if the nearest pond or stream is some way away. You can attract lizards and hedgehogs by creating spaces where they can hide from predators, such as piles of stones or branches, or leaving part of your garden overgrown. If you leave such shelters available in the winter, they may hibernate there, so they are ready to go to work for you as soon as the spring sun stirs everything into life. Hedgehogs will come regularly if you put out food to attract them, so why not spread some peanuts around your lettuce instead of slug-pellets?

Many insects are also useful for keeping pests under control. Ladybirds and lacewings can control greenfly, so are welcome in the garden. You can encourage ladybirds and lacewings by providing over-winter shelters for them, so-called ‘insect hotels‘ where they can hibernate safely. A greenhouse or garage is a good location for such a hotel, anywhere dry and sheltered, preferably away from the worst of the cold.

It’s also possible to deter the pests from staying in your garden in the first place, by a technique called companion planting, or co-planting for short. Some plants deter pests, so can confer their protection on their neighbours. Others attract insects that eat the pests, so achieve the same result. Some plants actually attract pests, and can be used to draw them away from your preferred plants. Many of these companion plants, such as herbs, marigolds, or sunflowers, are easy to grow, and desirable in their own right.

You can also choose plants that are less susceptible to pests in the first place. Maybe a honeysuckle will go nicely on that wall instead of a climbing rose, which is likely to suffer from aphids. Need tall flowers for the back of the garden? How about collecting seed from Common Mullein (Verbascum Thapsus) and planting that. They look just as good as any expensive hybrid you’ll find in the garden centre, and being a native species, they’re probably more tolerant to pests.

We can also help nature directly, rather than just letting it work for us. Instead of cutting down dead plants and burning them at the end of summer, consider leaving them alone until the seeds have set. Sunflowers look just as pretty with blue-tits and goldfinches hanging from them in October, picking at the seeds, as they do when in full flower. When the time comes to cut them down, why not add the stalks to the pile of branches for your hibernating garden assistants, and place the heads around your roses where they will decay in time to fertilise the new growth in spring. Plant a few late-flowering species to help the last insects of summer. Leave your dandelions alone in spring so they flower, the first bees to come out of hibernation will love them.

If you really want to go green with your garden, and can invest some effort to do so, growing your own vegetables is a great idea. By growing your own you can really cut down your carbon footprint by reducing your ‘food miles‘. That means that, instead of someone in the next country growing the stuff, packing it in plastic, and driving it to your local supermarket, you just get it from the garden, and all that plastic and fuel is not needed.

So, making our garden environmentally friendly is not difficult, it only takes a little planning and foresight. Our own environmental footprint, and the quality of wildlife in and around our garden, can vary a lot depending on the approach that we take. You might even save yourself time, money, and effort, and end up with a more satisfying garden as a result.

Summer has gone, Autumn is here. Trees are shedding leaves, flowers are fading fast, and the house-martins left a while ago. But as Jane points out in Urban Extension, sometimes there are new things to see in Autumn. I haven’t seen her special bee yet, though I’m keeping an eye on the ivy near my home. However, I have seen lots of other interesting things recently. Here’s a selection taken from a walk through the country lanes near Divonne two weeks ago.

At the top is a Pale Tussock moth caterpillar (Calliteara pudibunda). This guy was crossing the road, intent on going somewhere. I’ve never seen one of these before, but this must be the season for them, because we found another further on. They’re rather striking, the tufts make them look like a toothbrush!

There are still some flowers around, and yes, there are insects keen to visit them. This bee and the fly were just two of the more co-operative characters we encountered.

Autumn is, of course, a good time for fungi. I don’t know the names of any of these, maybe Winter Woman knows, she’s keen on fungi.

Further on, there were plenty of other insects crossing the road. On the left is a forest bug (Pentatoma rufipes). On the right is a dragonfly, a ruddy darter (Sympetrum sanguineum), who very obligingly stayed still long enough for me to take his photograph. That doesn’t happen often.

All the insects shown so far were actually on the road, for reasons only they know. This great green bush cricket (Tettigonia viridissima) was no exception. Dweezeljazz almost stepped on it, but she saw it just in time. It then hopped into the grass at the side of the road, making it much more photogenic. The Rhopalus subrufus on the right was on a wall in Divonne. Not exactly its native habitat, but well-placed for the shadow to show details you can’t see on the actual insect, so I’m quite happy with this shot.

It’s not just insects out and about in the Autumn sunshine. I was rather lucky to get a shot of the lizard before he dived under cover. The frog did dive for cover, but then drifted out to take a look, and stayed still for the photos. Very kind of him!

There’s still plenty of action on the plant front too. There are many flowers to be seen, even if they are mostly small and unspectacular by comparison with the competition in summer. These blue flowers are some of the largest still around. But even without flowers, there are some very pretty plants, like the Verbascum rosette. Elsewhere in our contryside, there are verbascum plants in their second year which still have some flowers left on them, bright against the brown of dying vegetation. Meanwhile, these first-year rosettes look very pretty in their own right.

Then there’s this old apple tree, which has sufferred badly in the late summer storms. Despite this, it’s still doing a good job of maturing its fruit, you can see there’s no shortage of them still on the tree. It’s clearly not giving up without a fight.

I have written about my vegetable garden before, but I have another garden, a secret garden. It’s not secret because it’s hidden, on the contrary, it’s in full sight of everyone. No, it’s secret because I do nothing to make it grow, nothing to make it flower. My secret garden is the wild flowers around me, which I find as beautiful as any domestic garden I have seen.

There are lots of different sorts of flowers in my garden. Even the dandelions of spring are a part of it, fields of yellow that are just lovely to see, and which provide the emerging bees with some of their early-season food. For the most part, I don’t know the names of these plants. If anyone does, please, let me know!

There are lots of these daisy-like flowers, simple yellow-and-white things. I have no idea what the blue flowers below them are called, but the bees love them. So do I, the way the pink buds open to reveal blue flowers is quite something. They’re not quite as common as some of the other plants, and the flowers are a little more hidden below the upper leaves, so they’re a bit harder to find. But they’re worth it.

Then there’s one that I can name, Verbascum Thapsus, above. I learned their name quite by chance when my good friend Shannon mentioned them in her “Wildlife in Summer” blog-post recently. She has a photo of some of them flowering on a rooftop, having somehow found room to put out roots. According to Wikipedia, Verbascum Thapsus is a biennial, so those plants had been there for a while! They flower tall and bright, and they flower for a long time. I bet that if they were annuals instead of biennials, they would be popular with gardeners.

Thistles are commonly regarded as weeds, but the flowers are really quite pretty. The thistle has been the emblem of Scotland for over 700 years, and the story of how that happened is rather amusing.

I found this ‘Checkered beetle’ (Trichodes Nuttalli) on a thistle very close to my home. I’d never seen a beetle quite like this before, he’s really very colourful. Thanks to “The Marvellous in Nature” for a post just a week or two ago which identifies this critter!

This next lot, I have no idea what any of them are called. The spiky plant above is really quite impressive up-close, and I’ve seen that in winter the birds come time and again to pick seeds from it, so it’s worth encouraging. The pink flower to its right grows on small shrubs that flower profusely, one or two of them would fill a niche in a garden very easily. The yellow flower to the right is much smaller, but close up it’s really very delicate.

Then there are some more familiar plants, like the poppies that come up everywhere in spring and the pale blue cornflowers that follow them in summer. The flowers change with the seasons, but there are always so many to see, all through the spring and summer. I’ve only mentioned a few in this post, maybe I’ll show you some more of my secret garden later on. Stay tuned!
