A crop of toadstools

In the pouring rain of a grey mid-November day I noticed, through our French windows, some toadstools growing in Wbx.  On closer inspection in better weather conditions next day, they were clearly one of the smaller Coprinus but overnight had started to autodigest around the edges into the inky black liquid characteristic of this genus.

In all I counted about ten fruiting bodies in different places, so the mycelium must spread widely through the window box soil.

Fifth birthday for this project

The window box has now been going for five years and all the plants appear to be doing remarkably well.  This is particularly surprising as I have given the soil no fertiliser and it must be getting some extra punch from the nitrogen fixing clover and tares and maybe from nitrogen in the rain water or tap water which I apply to the box in dry weather.

Today I coppiced back all the woody species - the sallows, the Himalayan honeysuckle and the tutsan.  The goat willow (Salix caprea) had one stem that had grown exactly five feet (1.52 metres) from the stool since it started this spring.

The two pictures below show the before and after situation.

20101104 Wbx 008

Some of the leaves on the goat willow had some small, tent-like leaf mines between the veins and I am pretty sure these are made by the larvae of a micro moth, the long-streaked midget (Phyllonorycter salicicolella), though I may have to wait for a spring hatching of the adult moths to be absolutely sure.

20101104 Wbx 009

As well as a new insect record, I found a new plant for the window box - a young goosegrass (Galium aparine).  There's life in the old box yet, although the plastic gets increasingly fragile.

My final picture is of berries on the Himalayan honeysuckle, appropriate for this "season of mists and mellow fruitfulness."

New flower, new spider-hunting wasp

The plant of Himalayan honeysuckle (Leycesteria formosa)  first recorded in the window box in 2006 is carrying its first flowers.

20100804 Wbx & South View 013

These flowers dangling from red bracts are followed by berries that, by all accounts, are edible so I might be able to harvest my first Wbx crop in a few weeks time.

While photographing this I noticed a small, black spider-hunting wasp sitting on a Wbx tutsan leaf.

20100804 Wbx & South View 021

This is Anoplius nigerrimus, a common species here but one that scarcely ever stays still long enough to get a decent photo.  This one was very obliging and seemed to be taking an unusually long rest on the leaf.  Later though I saw it restlessly hunting for spiders with its usual agitated, questing character.

Different sallows

There are four self-sown sallow willows in the window box, all of which have been there for several years and are coppiced each winter.

They all differ quite markedly in leaf size and shape.

Wbx Sallow leaves 20100802

Top left is, I think, undoubtedly rusty sallow (Salix cinerea ssp. oleifolia), a common and widespread species in Britain, while the large leaf beneath is goat willow (Salix caprea), also common.  The two on the right are probably Salix x reichardtii, hybrids between the first two species, also common.

Detailed accounts of all these species are given in BSBI Handbook No 4, Willows and Poplars of Great Britain and Ireland by R. D. Meikle (1984).

Tutsan caterpillars

Some of the leaves of the Wbx tutsan (Hypericum androsaemum) have been rolled up by small green caterpillars.

20100626 Wbx tutsan caterpillar 006

I suspect they are one of the omnivorous micromoths, but they could be the  greater purple flat-body (Agonopterix liturosa),an Oecophorid moth .  I'll have to see if I can rear one to adulthood.

In the picture above you can just see the tail of the caterpillar sticking out at the stem end of the leaf.  Below, looking down the tube, you can see its head.

Midsummer box

Today is the formal start of summer and the box is looking quite pleased with itself.

20100621 WBX 002

For some time it has been against the east wall of the house from where my wife, Cynthia, can see it, hence the grape vine leaves in the background.

The white clover now covers most of the ground and is flowering.  The tutsan on the right is doing well as is the Leycesteria towards the left.  The reddish leaves are of herb robert which is now coming towards the end of its annual cycle.

It is good to see the box doing so well after last winter when it was frozen solid for weeks.

Year five begins

This window box project was started on 4 November 2005, so today we are entering the fifth year.

20091104 Wbx 003

Over that period the box has travelled to Islay in Scotland and Bill Oddy's garden in Hampstead; it has featured in many magazines and papers and has given me a great deal of pleasure and interest.

There is no reason why it should not go on for many more years, though the plastic seems gradually to be getting more brittle and breaking down. I hope, however, to find something into which it can fit lock, stock and barrel.

Today I collected four insect species by sweep netting over the box: a bark fly (Ectopsocus petersi), the springtail Entomobrya nivalis and two flies - Lyciella rorida and Geomyza balachowskyi. The Ectopsocus and the Geomyza are both new records for the project.

The biggest surprise though was a fine crop of toadstools around the base of the rush plant.

20091104 Wbx 006

They are, I think, glistening ink-caps (Coprinellus micaceus) perhaps using the underground part of the sallow log as a medium on which to grow, though they seem to be more associated with the decaying materials at the base of the rush

Rabbit revealed

For some time plants in the window box have been somewhat bitten down.  Mainly it seems to be the leaves of the white clover that disappear, but something has chomped at one of the sallow bushes.

At first I discounted rabbits as it seemed much too difficult for these animals to climb up onto the wire crates that keep the top of the window box up to about waist height.

I have, however, caught the culprit in the act and it is indeed one of our bolder lawn rabbits.  This is one record I had not really expected - I hope this bold Brer does not feel inclined to make a burrow.

20090902 South View EVT etc 004a

I am quite happy to let the creature have as much of the clover as it wants and we will have to see about the long term effect.  Meanwhile I reckon I have one of the few window boxes in the world that boasts a wild rabbit visitor.

Sallow Muppet

The leaf-cutting bees have been at work on the leaves of one of the sallows.

20090723 South View Wbx Swallowtail 002

This example strikes me as having a curiously Muppet-like appearance.

Late spring apogee

The window box is just going over from a kind of aesthetic apogee that so often happens in nature during the run up to midsummer. Everything is fresh and bright with a bit more growing to do before the dustiness of summer and the first hints of autumn start to appear.

20090617 South View 005

At the southern end of the box the tutsan (Hypericum androsaemum) has flowered and a faded one is now forming a red berry that will soon turn black. Around and about the tutsan are half a dozen flowers of white clover that attract the occasional bumble bee. Hairy tare (Vicia hirsuta) pruned so drastically a few weeks ago has sent more delicate vines up to the light and their tiny mauve-white flowers thrust boldly forwards on long pedicels, challenging the variable breezes.

At the northern end of Wbx, a place that could now perhaps be called a copse, this year’s goat willow wands are one third of a metre high as are the new shoots of the Himalayan honeysuckle. The grey sallows are not so fast but look in good health.

The soft rush is just coming into flower and, deep in the foliage, the filigree leaves of herb robert are gathering strength for the plants that will make a bigger showing in autumn or next spring.

Bullfinches and vetch mulch

I am quite proud of the above post title - slightly reminiscent of Shakespeare's "Like as the waves make towards the pebbl'd shore", though I was not, of course, planning to emulate the sound of breaking surf.

Some have thought though that Shakespeare was acknowledging Ovid who in Metamorphosis XV wrote:

sed ut unda inpellitur urgeturque prior veniente urgetque priorem

Anyway, enough of that. The other day a male bullfinch perched by Wbx and, I am sure, flew over the window box.

20090505 South View WBX 002

A somewhat misty picture as it was taken through our not-recently-cleaned sitting room window.

These beautiful little birds pass through our garden once or twice a year searching for seeds and buds. Sadly they are now of the RSPB's Red List - the highest conservation priority, with species needing urgent action. To quote from Shakespeare's sonnets once again:

From fairest creatures we desire increase,

That thereby beauty's rose might never die

So, on to the second part of my title, the vetch mulch. This is simply that I took the quarter pound of hairy tare I gathered from Wbx the other day, dried it and crumbled it as a light mulch over the upper surface of the box, brushing it down to soil level between the plants. By such actions I hope to build up the shrinking soil a bit, or at least to stop it declining so rapidly.

Management decision

The hairy tare of last year has seeded itself quite liberally and over the last few weeks and has been growing with great vigour.  It rapidly smothers other plants and its weight is so great that it pulls them down to the ground.

 20090502 WBX   Hairy tare 005

So, I decided to remove the plants and give more space for the other things to develop.  The results are depicted below.

20090502 WBX - Hairy tare 044

I kept the tare arisings and weighed them indoors: 100gm (approx. 4 oz).  I have put it out to dry as hay and may then crumble it up to return to WBX.

The little things in life

On St David's day I found this tiny springtail, Entomobrya nivalis, sunbathing on the edge of the window box.

20090301 Metre & Ice House 001

Also, on top of the central sallow log I found a few strands of moss emerging from the cracks.

20090228a Wbx moss b

I reflected that this project is in the spirit of St David's last words when he told his brothers and sisters to be joyful and "do the little things in life" (Gwnewch y pethau bychain mewn bywyd in Welsh, his native language)

A Wealden wood

With its complement of fallen leaves lying on the moss and the various plants arrayed around within the window box, I noted that it now looks very much like a small rectangle of Wealden woodland floor.

This is not surprising as this is exactly what the area where the window box is situated would have been before the land was cleared by human activity.

20081221 Wbx at midwinter 001

I feel quite pleased as it would be almost impossible, or very difficult to produce such an effect quickly and deliberately.

The photo was taken on 21 December 2008.

Target leaf-spot fungus on clover

20081120 Wbx clover fungus 004

Some of the leaves of the white clover (Trifolium pratense) has developed target leaf-spot fungi, probably, I think, Stemphylium sarciniforme (there are many leaf spotting fungi found on clovers and they all look very similar unless studied under a high power microscope).

They are called 'target fungi' because they tend to make target-like concentric rings on the leaf.

Fourth year begins

Today the window box had its third birthday and now sets off into its fourth year.

20081104 Wbx

I took the picture above from the rear to avoid it looking exactly the same as the ones taken a couple of days ago.

I must repair that rim sometime - the consequence of journeys to Islay and London with TV crews.

At least the soil does not seem to be shrinking so much and I am thinking of ways of building it up with box-grown stick bundles and blown in fallen leaves.

World's smallest coppice?

I have, as I do every year, cut back my three sallow trees (actually two grey sallow, Salix cinerea, and one goat willow, Salix caprea) now all the leaves have gone (mostly eaten by sawfly larvae).

The pictures below show the situation before and after the coppicing and sharp-eyed visitors may be able to see where some of the twigs top left have disappeared.

20081027 Wbx 002

20081027 Wbx  003

I took the cut off twigs and shaped them into a bundle.  I call these 'woodcharms' but I suppose the correct term is 'faggots', a word deriving from the same root as 'fascist' (from the bundles of rods, or fasces, carried by people in power and authority in ancient Rome). 

20081027 Wbx Salix woodcharm faggot

A faggot was, like mine, bound with two ties.  If only one tie had been used it would have been a bavin (I now feel moved to make a bavin so I can legitimately use this word).

My faggots are also a bit small.  A short faggot would have been 24 inches (61 cm) round and 32 inches (81.3 cm) long and a long faggot 24 inches round and 48 inches (121.9 cm) long.  I guess mine is a microfaggot.

I have put this microfaggot alongside the northern end of the window box and one of the cut sallow stools can be seen top right of the photo.  Hopefully this will help to rebuild the soil level which still continues to shrink and drop.  This year I will leave any fallen leaves that blow into the box, though I don't think these will help much.

The striped gold midget

Some dark blotches on several of the leaves of the Himalayan honeysuckle (Leycesteria formosa) have proved to be the upper side of the leaf mine of the striped gold midget (Phyllonorycter emberizaepenella).

20081018 P emberizaepenella 3

'Phyllonorycter' means 'leaf-digger' and 'emberizaepenella' 'bunting-winged' so the vernacular name should, perhaps be 'bunting- winged leaf-digger'. But there are some further complexities with this wonderfully Ciceronian scientific name: the second half of the specific name derives from Latin penna meaning a wing. This would give two n's in emberizaepenella and the fact that there is only one is said to be a typographical error. Unless a properly recorded earlier version of the specific name of this moth is found the misspelt version has to remain under the international rules of nomenclature.

The moth is said to widespread but very local and the larvae feed also on honeysuckles and snowberry. There are no records for the species in East Sussex in the Sussex Biodiversity Record Centre's database. There is however a dot for East Sussex in The moths and butterflies of Great Britain and Ireland, so it must have been found. It is, however, listed by the Record Centre as occurring at Ebernoe Common, West Sussex.

More Nematus pavidus sawfly larvae

A few weeks back a colony of Nematus pavidus sawfly larvae fed up on one of the sallow in Wbx.  Recently a new colony appeared, founded I suspect, by an adult of one of the earlier larvae.

Today I noticed that there were three ages: the small white worms and their left behind eggshells, some rather large larvae but still with some growing to do, and some really big ones almost ready to pupate.

20080921 Wbx Nematus pavidus 016

There was also a parasitic wasp (ichneumon or braconid) pottering about nearby and maybe looking for an opportunity to lay eggs in some of the sawfly larvae via that vicious-looking ovipositor.

A sawfly: Nematus pavidus

20080809 South View Nematus pavidus 1)

The baby sawfly larvae spotted recently on the goat willow (Salix caprea) have turned out to be Nematus pavidus, confirmed by John Grearson of Symphata: The Sawfly Forum (a very useful Internet discussion group for those interested in British sawflies).  The picture above shows two mature examples on the window box.

N. pavidus does not appear to be at all common.  There are no records on the Sussex Biodiversity Record Centre's database and none for Sussex on the National Biodiversity Network.  Indeed there are only six 10km squares in Britain from which the species has been reported, including one that covers Lundy Island.

Although the caterpillars are very obvious, working out what they are was not easy and, as with many sawflies, the adults may not be much in evidence, so it is probably under-recorded rather than rare.

Whatever the case, they have turned many of the goat willow leaves into fretwork, though I am sure this will do no long term damage.
