two hedgehogs eating peanuts

Our terrace is inspected every night by the local night watch. They go over every inch of the grounds, looking for intruders that shouldn’t be there. They’re quiet and unobtrusive, doing their work efficiently and without supervision.

They first appeared a couple of months ago, not long after the last snows melted here. We first found evidence of them in the droppings they left behind. When it comes to animal droppings, I don’t know – much, but a few minutes with google confirmed that these were likely the work of those cutest of creatures, the hedhehog.

Sure enough, it turns out that we have not one, but two (at least!) that come round for a nightly visit. Around 10pm each evening they squeeze under the garden gate, help themselves to a meal (breakfast?) of peanuts and sunflower seeds, then set off on their rounds.

(These photos are rather poor quality because they were taken without flash, so they are several-second exposures. I don’t like to use flash on animals, especially nocturnal ones.)

When we realised who it was that was visiting us at night we started putting out more nuts for them, instead of just letting them have the leftovers from the birds. After all, the birds don’t leave much! At first we left peanuts in their shells. The hedgehogs made short work of them but also left something of a mess, with bits of shell everywhere. After looking around the internet for information on how to feed hedgehogs, I found very little that talked about peanuts. So I contacted the British Hedgehog Preservation Society, to ask their advice.

Fay Vass promptly replied, telling me that unsalted peanuts are fine, but that they should be chopped or crushed, as whole or half-nuts can get stuck in the roof of their mouths. Thanks for the advice, Fay, they now have a diet of chopped nuts and sunflower seeds to start their evening.

You might think that the British Hedgehog Preservation Society is a small group, tucked away in some quiet place in the English countryside. Small they may be, but that hasn’t stopped them from taking on McDonalds over their hedgehog-unfriendly packaging, successfully persuading them to redesign it so hedgehogs can’t get stuck in it. Good for them!

So now, thanks to the British Hedgehog Preservation Society, our local night patrol is well and safely fed. They eat for 15-20 minutes, then they’re off on their rounds, keeping our terrace slug-free.

And the best thing of all is that they work for peanuts!

...still eating...

Green Gardening

Tony — Mon, 12 Apr 2010 19:38:20 +0000

my garden in 2009

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.

verbascum thapsus

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.

James Camerons’ new science-fantasy film, ‘Avatar’, starring Sigourney Weaver, is doing the rounds at the box office in Geneva. I saw it recently, and I have to say, it’s an amazing film. See it in 3D if you can, it’s worth it.

Without giving away too much of the story, I can tell you that it’s set in the future where humans travel to a planet called ‘Pandora’ to mine a valuable mineral from under the feet of the indigenous natives. The natives don’t want to give up their lands, of course. The humans attack them with the usual military hardware, and the natives fight back with bows and arrows. Nothing particularly new there, the plot has a familiar ring to it.

Nonetheless, Avatar stands out from the crowd. James Cameron is not known for thinking small, and the visual effects are quite stunning. The landscapes are exquisite, and the plants and animals are beautiful. Bio-luminescent plants glow underfoot where people walk at night. The whole thing is put together superbly, with a great deal of attention to detail.

The natives (“Na’vi”) are tall and elegant, and more than a little elfin in appearance. They live in harmony with their world, respectful of the living things they share it with. Taking no more than they need to survive, they deplore the humans’ lack of balance with nature. When the tribal-chief’s daughter rescues one of the humans from a sticky situation (I told you the plot was familiar), she chastises him, telling him “you do not see”. Like so many of us, he considers himself to be separate from the web of life around him, not a part of it, so he is blind to the real beauty of it all.

It seems that message has struck a chord with many of us, and some people get depressed after seeing Avatar. They envy the Na’vi their lifestyle, and are not happy to think that they can never live that way, nor live in such a beautiful place as Pandora.

I guess I can understand that, but I don’t agree with it. The Pandora that James Cameron has created is indeed very beautiful, and the Na’vi have a great way of life. Sure, they occasionally have to dodge things with teeth the size of their heads, but apart from that, they seem to have it made. But while Pandora might be a nice place to visit, I don’t think I would want to live there. Planet Earth is my home, and I’m happy here.

It’s true that most of us cannot claim to live in harmony with nature. Probably only a few of us would want to go as far as the Na’vi, but we can probably do better than we do today. All we need to do is to go out there and start looking around, the natural world is just waiting to be found.

You don’t have to go on safari either, nor to a tropical island. You can go to your nearest beach, lake, river or woodland, and take a good look around you. You can go down to the bottom of your garden, or to the nearest park. Nature is at home in all sorts of places.

I’ve seen blue-tits working hard to bring food to their young in the nest they built in the shutters of my apartment window. I’ve even been lucky enough to see one of those chicks make its’ first flight, leaving the nest. I’ve seen baby birds clambering to hitch a ride on their mothers’ back, rather than expend the effort to swim alongside her. I’ve seen a pigeon raise a family in an empty flower-pot on my balcony. I’ve seen all sorts of pretty insects – caterpillars, butterflies, crickets, bees and beetles – in the plants I’ve grown on my terrace. Nothing unique or exotic, but all beautiful just the same.

It’s not just birds or insects either. I’ve had squirrels come up to me in Hyde Park, looking to see what I had in my hand. I’ve seen a hedgehog on my terrace, and frogs in my Mums’ garden. There are deer and foxes in the Jura that we sometimes see on our walks, or even from the comfort of our home. After a fresh fall of snow the sheer number of animal tracks has to be seen to be believed, there’s so many of them. We saw a weasel not long ago, and I’ve seen chamois and marmots in the Alps.

I’m no expert at finding these animals, I just go out and look. I don’t see them every day, but that makes it all the more precious when I do.

If you live in the concrete jungle and don’t have any countryside within reach, try visiting your nearest park. If there’s grass, trees, and flowers then there will be birds, bees, and other insects. Take some bird-seed and you might be able to tempt the birds to come close to you. Give them time to get used to you and they may even perch on your hand. Come evening, you may be lucky enough to see bats flying around too. If there’s a pond then there may be frogs or dragonflies hidden among the reeds.

If you don’t have time to go somewhere, you can put a birdfeeder in your garden, on your balcony, or just mounted on the wall outside your window. Birds will find it, and you can enjoy them from the comfort of your own home. You can really see their characters emerging when you see how they behave around a feeder, it’s fun to watch.

If you’re not sure where to start looking, there are plenty of good sources of information. Your local library or tourist office can tell you about nature-groups, natural attractions, or forthcoming nature-related events in your area. If you know someone more experienced, ask them to show you where to look. There are several good TV programmes too, such as Springwatch in the UK. Or you could search the web for nature-bloggers in your neck of the woods, and ask them a few questions. They’ll be sure to help you if they can.

I’ve not seen anything as big or colourful as the creatures that the Na’vi encounter on Pandora, but fair’s fair, I’ve not met anything that tried to eat me, either. If you take the time to go looking for it, nature is never far away. Go take a look, you’ll see.

Garden visitors

Tony — Mon, 28 Sep 2009 19:44:46 +0000

My little organic terrace-garden has been rather successful this year, and the produce has been very welcome at our table. We’re not the only ones to appreciate it, naturally, there are plenty of critters who have helped themselves throughout the summer. That’s OK with me, I’m happy to share to some extent, providing they don’t eat everything.

beetroot leaf eaten by leaf miners

One common form of damage has been beetroot leaves eaten out from the inside by leaf-miners. There was a lot of this in early summer in particular, and I had little choice but to remove the affected parts of the leaves and throw them away. Otherwise I would have had very few leaves left on some of my plants! Apparently, some plants have evolved patterns of markings that look similar to the damage caused by leaf-miners, which protects them because the leaf-miners prefer unoccupied leaves in which to lay their eggs. Maybe I’ll ask Dweezeljazz to go out and paint the leaves for me next year, that sounds like a job for an artist!

There have been any number of butterflies hovering around the garden, even well before there were any flowers in evidence. They must have had something else in mind and yes, sure enough, I have found lots of eggs hidden on the leaves. Some were quite hard to spot, among the beetroot in particular. Some were easier, like the yellow eggs on the nasturtium leaves.

Butterfly eggs, of course, hatch into caterpillars, and I have found quite a number through the summer. On the left is a ‘Small White’ (Pieris rapae), this one was just running around the rim of the pot like he was desperate to find the end of it. I don’t know what the one on the right is called. Below them is, I think, the caterpillar of a Garden Tiger moth (Arctia caja). Apparently, Tiger Moth numbers have been decimated in the last 30 years, due largely to excessive use of pesticides. Like many other small creatures, they are now in need of protection in the UK. This one was running across our living room floor at high speed, heading for the stairs, looking for a place to pupate. He was safely redirected to the great outdoors!

beetle on sunflower

There have been a number of other insects, such as this bright green beetle (probably a Chrysolina species), and the two crickets below.

The one on the right is Roesel’s bush cricket, (Metrioptera roeselii), and this poor specimen has lost one of his hind legs. Despite this, he was quite agile, climbing easily, and was able to manage a decent hop when I picked him up and released him in the nearby bushes.

goldfinch on sunflower

It’s not just insects that visit our garden. After being absent this summer, the goldfinches are back, this one investigating the sunflower heads for seeds. Well, that’s why I planted them! I know it’s not a good photograph, but it’s the only one of a goldfinch that I have at the moment, so it will have to do. Hopefully I’ll get better photos later.

Although not closely related to the American goldfinch, it does share its taste for sunflower seeds!

hedgehog

Finally, late one night a few weeks ago, we found this hedgehog doing the rounds on our terrace. I don’t think he found anything edible, but he’s welcome to come back anytime. Again, not a perfect photo, but we don’t like to use flash on animals, especially nocturnal ones. He wasn’t hanging around for us to get many shots, this is the only one we got of him too!

I haven’t any photos of all the bees, butterflies and wasps that have visited my garden too. Maybe next year. It’s amazing how much variety you can get visiting just a few pots of plants.
