The establishment and management of orchards in the UK probably started in Roman times.  The organised growing of apples, pears, plums and cherries developed during the 1st to 4th centuries of the CE.  However, with the withdrawal of the Romans, the management of many orchards declined, though it was maintained in some monasteries. These orchards offered such communities stored / preserved fruit, ‘medicines’ and cider.  Later during the medieval period, orchards were often present in manor houses, outside of villages, monasteries and other community settings.  Most of the orchards grew apples and pears, though cherries, plums / damsons were also grown.   Moving on to Tudor and Stuart times, these were good times for orchard and fruit expansion in general.  A wider range of varieties became available, pruning and grafting techniques improved, as did the layout of trees within orchards.  Books were written on fruit and orchard cultivation by people like John Gerard and John Evelyn (his contribution on fruit trees appeared in the appendix of ‘Sylva’ - entitled Pomona); so good practice spread.  Some orchards were part of a mixed use landscape, where grazing animals wandered between the trees.  Such orchards are sometimes referred to as ‘heritage orchards’, in contrast to more modern techniques of orchard management.  Further changes took place in the 18th and 19th centuries which saw the introduction of many varieties of fruit e.g. Kentish Cherries and Herefordshire Apples. At this time orchards reached their greatest coverage in our landscape. However, the 20th century saw a sharp decline in the maintenance and number of orchards.  The decline was due to a number of factors : Traditional orchards are long lived but require regular management Two world wars - these encouraged the use of land for increased food production / arable crops.   Urban expansion and increased need for housing and transport networks resulted in the loss of many city and village orchards Cheaper imports of fruits Subsidies and grants supported the removal orchards. Also, some  orchards survived but heritage / traditional orchards with tall, widely spaced trees were grubbed up and replaced with low stemmed, high density planting. These trees bear fruit after a shorter period of time and the collection of the fruit can be done mechanically.  Sadly, such trees support less wildlife. Beers and lagers replaced cider as a traditional drink, traditionally it was supplied to farmworkers / labourers. Supermarkets wanted fruit that was unblemished with a long shelf life. Plus, the demand for certain apple varieties (e.g cooking apples) fell. Now, orchards are recognised as valuable habitats and community orchards are being re-established.  A community orchard is a shared space, which support fruit and nut trees.  The trees grown include apple, pear, cherry, plum, walnut and hazelnut. Sometimes there is an understory of soft fruits, various herbs and plants which support pollinators of the trees. The community orchards are normally looked after by local people or organisations and ‘managed’ by local groups such as ‘not for profit’ organisations, the local council or a specific neighbourhood group. The orchards are usually open access / semi public, with the harvests shared with the volunteers and the local community, providing fresh local food.   The harvesting of the fruit, nuts and sometimes vegetables varies from ‘pick what you need’ to ‘an organised distribution’ to ‘local food banks’ and ‘community kitchens’.  To find out more about community orchards and if there is one near you - visit the Orchard Network at the Peoples Trust for Endangered Species.

No match for nonpareil ? Many varieties of apples have been around for centuries.  For example, the nonpareil which was bred (in France) back in 1696, the Egremonet russet much admired for its flavour and appearance dates from Victorian times. The  Cox's Orange Pippin is a cultivar first grown at Colnbrook in Buckinghamshire by Richard Cox.   By end the of the C19th, the Cox’s pippin was one of the most popular apples. However, there is a concern for these heritage apples in our changing climate.  In recent years, we have experienced warmer and wetter winters.  Such winters do not offer enough chilling hours for these trees.  Many trees need a period of cold in the winter months, where the temperatures are below 6oC but above freezing.  About 1000 chilling hours are needed for apples such as the nonpareil.  However, winters are present are offering approximately 600 chilling hours. Gala apple trees (developed in New Zealand) need only 600 chilling hours but it might be that they will not respond well to the wet winters we (currently) experience.  Some feel that they do not offer the complex flavours of ‘classic apples’.   Kew Gardens has now planted a varied selection of apple trees One third are heritage apple trees One third are ‘new’ varieties needing fewer chilling hours One third are varieties from countries warmer than the UK Over the coming years, the trees will be monitored to see which ‘do best’ in terms of cropping in London’s warming temperatures. The apple-growing industry in the UK is under considerable strain, with many growers unable to afford replanting this year.  Growers ‘refresh’ their orchards regularly, replacing older trees with new ones, but now many cannot afford to do this.   The sector is struggling with  a shortage of workers - made worse since the UK's exit from the European Union  high energy costs low returns from the supermarkets that buy their produce The option to ‘buy British’ may become a much rarer option.   Further details here Recovery after forest fires. Bacteria and fungi are the first to start rebuilding from the charred remains of burnt forest and woodland.  The number and variety of microbes falls dramatically after a fire.  Then, there was a microbial succession in the burned soil, that is, the number and types of bacteria and fungi changed quite quickly, with fast growing types able to advantage of the reduced competition for resources.  The situation is not dissimilar to what happens to our gut microbiome when we have to take antibiotics.  Antibiotics ‘knock out’ many of the useful bacteria in our gut, but gradually the microbiome is re-established.   Reporting on weeds. It seems that our gardens may be home to ‘new’ or unusual species of plants.   The Royal Horticultural Society would like gardeners to report on interesting ‘weeds’ that might find as they could be rare plants or plants growing in unusual places / areas.  You are asked to take photographs of anything that you find interesting and upload the images to iNaturalist. Reporting on unusual plants is not the only thing that the RHS is interested in. There are other garden projects that one can contribute to, for example, reporting sightings of garden pests such as the berberis sawfly, cellar slug, hemerocallis gall midge, lily beetle, rosemary beetle and spittlebug.

The woodlands blog has reported on the anthropocene - how human activity is creating a geological era characterised by human impact on the Earth.  Now a report finds that human-made (artificial) material will this year surpass the sum total of all living material (biomass) on earth. https://www.nature.com/articles/s41586-020-3010-5 A Swedish study has shown that crop yield can be enhanced  by ensuring that woodland and grassland areas are present in the vicinity of crop fields.    If the landscape is more diverse in terms of plants and habitats, then the number of pollinators (bees snd bumblebees) is greater.   Read more...

When you look around this week, you might see suspended from the ceiling or a light fitment - a rather sad and shrivelled piece of mistletoe.  Mistletoe is well known for its connection to Christmas, in particular for the custom of “kissing underneath the mistletoe”.  The mistletoe has separate male and female plants; it is DIOECIOUS.  It follows that the male plants will not produce berries and they have no commercial value - as they do not yield berry-laden sprigs for Christmas decorations.  This use of mistletoe may be rooted in festive legends of 'fertility and life giving powers'.

Dr Dara Stanley of New Holloway, University of London has been looking at the effects of neonicotinoid pesticides on the ‘efficiency’ of bumblebee pollination of apples.  Several studies have already implicated these pesticides in the decline of foraging behaviour of bees / bumblebees.  As some 30% of agricultural crops depend on pollination by bees and  bumblebees, hover flies and other arthropods (with an estimated global value in excess of $350 billion / year) then the effects of these pesticides needs to be evaluated, so that informed debate on the banning or restriction  of their use can take place. Dr Stanley and associates exposed some bumblebees to ‘low’ levels of neonicotinoids (such as might be found in wild flowers), others were exposed to no pesticide.  Read more...

It has been a rather strange year.  After another dry winter – March arrived and was one of the warmest and driest on record; consequently, many of us were threatened with restrictions (on hosepipes etc)  as a severe drought threatened - many reservoirs were very low on water. But then came April, which was one of the wettest recorded in the UK.  Some 121.8 mm of rain fell, beating the previous record of 120.3 mm -which was set in 2000; some parts of the U.K. had three times the ‘normal’ amount of rainfall. June was also very wet and set a record. There then followed the wettest summer as a whole since 1912.   The final rainfall figures for the year have been released and the total rainfall for the UK during 2012 was 1,330.7 mm (52.4in), just 6.6mm short of the record set in 2000. The big winners in these wet conditions were slugs – including the giant Spanish super slug, or Spanish stealth slug that was reported to be invading gardens.  These have an  ‘enhanced’ breeding cycle producing many more eggs Read more...

Bees are important pollinators, especially for crops like apples.  The UK apple market is estimated at some £320 M per annum. Though current estimates vary, it is pretty much certain that this year’s apple harvest will be down, perhaps only 50% of that of a ‘normal’ year.  Though the trees produced blossom in plenty and all looked good for a ‘bumper harvest’ – it then rained and rained. Because of the weather, there were few bees, bumblebees or other pollinating insects.   This has not been a good year for bees (or indeed, bumblebees).   Why? Read more...

We have experienced an extended and warm autumn, and now true to Pliny's words - "A fair and dry autumn brings in always a windy winter" - winter weather has now firmly settled upon us.  The temperature is down to "more representative" seasonal values for December, and cold, high winds have recently lashed Scotland and other parts of the U.K. The warmest Autumn (for some 300 + years) was in 2006, when the temperature was some 2.4 / 3 oC above the seasonal average ; places like Kinlochewe recording a daytime temperature of 22.5 oC.   The recent mild weather * was due to an unusual pattern of high altitude winds over the Continent.  The course of the jet stream meant that there were southerly winds and relatively settled conditions over the United Kingdom.
