In the busy gardening seasons (Spring, Summer & Autumn), I will have two (occasionally three) hot composters running. During Winter, I will just maintain one active HotBin. In addition to my own garden waste, I also accept waste from up to six other neighbours. Every autumn, I receive a large amount (about 2 cubic metres) of hedge cuttings from one particular neighbour. More generally, neighbours drop off their garden waste intermittently in quantities of two or three 60L bags (Photo 2).
Photo 2: Large & Small Bags of Garden Waste
A few days ago, I took delivery of a large quantity of garden waste when the ivy/privet hedge belonging to a neighbour at the rear of our garden was heavily trimmed. The rear bag in Photo 2 is what remains of that delivery after I had shredded and fed some into my hot composters. A day later, the contractor who cut the hedge (Paul) popped round and asked if I was interested in taking more garden waste (lawn mowings and hedge trimmings in the main). I had, perhaps mistakenly, mentioned that I used hot composters to speed up the process. I agreed, on the basis that I could turn down future supplies if the amounts involved became too much, and immediately took delivery of another 400L of grass cutting and hedge trimmings (Photo 2, front bag). The next day, a further 200L of ivy cuttings arrived but I'm not expecting anything else for another week. Photo 3 is my current stock of garden waste but, at least, the 3 x 60L bags have been shredded and are composting away at 60 ℃.

With so much garden waste to process, I have had to change my modus operandi. In the past, my standard procedure was to half fill a hot composting bin with shredded waste/grass cuttings (50/50) using a minimum of 20L hot (50-60 ℃) partially-composted waste from an operating bin to kick start the process. Adding a couple of 2.5L bottles filled with hot water is an alternative way to kick start the composting process. As soon as the bin is up to temperature (50-60 ℃), usually the next day, continue to add shredded/kitchen/grass at the rate of 6-10L per day. At this rate it takes between 20-30 days to fill a bin.
To process the extra quantities of garden waste now available, I will be looking to fill the bins at a much faster rate as well as bringing my two Supercomposter bins back into action (Photo 4). The two Supercomposter bins are currently being used as (i) a store for shredded garden waste, and (ii) a maturation bin.
Photo 4: Supercomposter Bin in Use as a Maturation Bin
One of the Supercomposter bins is already in use and operating at over 60 ℃ after just 24 hours. So far, approximately 250L of shredded garden material is undergoing hot composting! I am also trialling the use of heat reflective coverings laid on top of the compost to retain and re-use the heat generated by the composting process. Currently, I'm using extra wide (450 mm) catering aluminium foil which is working well. The covering should only loosely cover the compost to allow for ventilation and easy egress of water vapour/steam (Photo 5). Early indications are that the reflective shield increases the rate of initial warming, maintains a greater depth of warming, and reduces the rate of cooling towards the cool-warm (<40 ℃) composting phase.
Photo 5: Reflective Heat Shield (Aluminium Foil)
At a later date, I will report in more detail on the benefits or otherwise of using a heat-reflective covering when hot composting.
The kitchen garden backs onto a row of terraced houses. Along this southern boundary, there is a giant hedge (Photo 1). Ivy dominates the hedge which overhangs our boundary. Occasionally, I will trim the overhanging vegetation, shred it and put it through my hot composting system.
Photo 1: The Walled Kitchen Garden
House sparrows nest and roost in this giant hedge. A cacophony of sound often greets me when I visit my composting corner but soon changes to an eerie silence apart from the odd chirp from a young house sparrow.
I got a bit of a shock the other day on my way to tend to the hot compost bins. One side of the hedge was much reduced in height. I could hear noises on the other side of the wall so called out and received a reply.
Photo 2: The much-reduced Ivy Hedge
I almost said that it wasn't the best time of year to be cutting down hedges due to nesting birds but I would have been wasting my breadth as the job had already been finished. My neighbour would have happily hacked down all the hedge if he had been able to access it.
Photo 3: Close-up of the Much-Reduced Hedge
Being neighbourly, I offered to take all the cuttings for my hot compost bins. I probably should have checked how much stuff there was before making the offer because he started chucking it over the wall (I had agreed to this).
Photo 4: Hedge Cuttings Covering the Maturation Compost Bins
Photo 5: Side View of the Cuttings Pile
It took me about 6 - 8 hours to cut up the hedge trimmings into 3" to 4" pieces ready for shredding. In all, I ended up filling the equivalent of 11 x 80L bins (approx one cubic metre) before the kitchen garden returned to normal. You can see in Photo 6 how much the height of the hedge had been reduced.

There were a couple of house sparrow nests in the hedge debris ...

... and, fortunately, no eggs or young. There is still quite a lot of the original hedge still standing so hopefully the sparrows will continue to breed and raise their young here. For the moment they are still visiting our bird feeders in good numbers.
In an earlier blog, I made reference to man's urge (it is usually men!) to tidy up nature and this is another example. I suppose the neighbour's garden lets in a bit more light and I've gained lots of greenery for composting but that doesn't, in any way, make up for the fact that some house sparrows are now homeless.
You can guess what month Hawthorn flowers from its common moniker, May Blossom. This year's display of flowers has been spectacular, especially in hedgerows where hawthorn is a dominant species.
I took these pictures on my way home from a citizen science outing after testing the Yazor Brook adjacent to the Environmental Gauging Station mentioned at the start of this guided walk. This popular and well-used walking/cycling route has benefited from ongoing improvements to the area in the form of the Yazor Brooks Restoration Project.

Cow parsley is also in full flower at this time of the year, often seen along the verges of country lanes.

Along this particular route, however, there are fields of it covering the floodplain of the Yazor Brook ...
Photo 3: Fields of Cow Parsley on the Yazor Brook Floodplain
It has been allowed to spread in an urban environment as the floodplain is unsuitable for building. No doubt its existence will be threatened someday by the inexorable desire of humankind to tidy up nature.

Only a couple of hundred metres away from this nature idyll is the sprawling industrial complex that includes Avara Foods and Heineken (formerly Bulmers Cider). Avara Foods (purveyors of chicken, turkey and duck products to supermarkets/restaurants) are considered one of the 'bad guys' with regards to the pollution of the River Wye and one of the reasons we need citizen scientists to monitor river quality. Unfortunately, Avara is part of the Cargill US conglomerate and they do not have a good record of environmental protection in their home country. There is no getting away from the fact that Avara is a major employer in Herefordshire and that it produces cheap protein-rich food (an important consideration in a cost-of-living crisis). The main issue is with the intensive poultry farms and how they dispose of the high phosphorus waste. Avara have stated that none of their poultry waste will be spread on land in Herefordshire which is a good start. Unfortunately, their preferred disposal route is via anaerobic digestion and there are environmental issues with this process.
December - the tenth (decum) month of the Roman calendar which became the twelfth and final month of the year in the Julian and Gregorian calendars. This month's photo was taken on Christmas Day (25th) when the winter-flowering cherry was in bloom, the heady fragrance of the sarcococca bush was divine and the Christmas tree was adorned with baubles.

December 2024 was mild, windy and relatively dry though lacking in sunshine. December's weather stats, collected by our garden-based Davis Weather Station, are presented in the table below:
The minimum and maximum daily temperatures for December 2024 are shown in Figure 1. With no frosts and moderate day and night-time temperatures, December 2024 felt unseasonably warm.
Figure 1: Min/Max Daily Temperatures for December 2024
Cloudy skies were the main reason for the absence of frosts and the relatively uniform daily temperatures -in other words, the sun remained hidden on most days (see Figure 2).
Figure 2: Daily Rainfall & Sunshine Data for December 2024
Figure 3 shows the highest daily wind speeds recorded by our weather station in December 2024. The highest wind speed of 61 km/h was recorded during Storm Darragh (5th to 7th December). Consistently strong winds throughout the UK, meant that wind power generated 39% of all the UK's electricity - more than any other source.
Figure 3: Highest Daily Wins Speeds Recorded in our Rear Garden (December 2024)
We now have weather data for December covering the period 2019 - 2024 which I have summarised in Figures 4 & 5. Over this period, the maximum December temperature has been creeping upwards (Figure 4) although it is still possible to get cold Decembers (2022, 2023; Figure 4). Rainfall is trending downwards, though not because it is sunny, while maximum wind speeds are on the up (Figure 5) - overall, good for wind power generation but not for solar PV.

Figure 5: Rain, Wind & Sunshine Trends in December for the 2019 - 2024 Period
The next three figures are taken form the UK Met Office's monthly report for December 2024. All of the UK experienced a mild December including our little corner of Hereford (Figure 6).
Figure 6: UK Mean Temperature Anomalies for December 2024
There was heavy rain in the northernmost parts of Scotland, but the rest of the UK had average to low rainfall (Figure 7). The Met Office's weather station at nearby Credenhill gives an average December rainfall of 72.67 mm (1991-2020 data), so the 52 mm (Table above) recorded in our Hereford garden is 25-30 % lower than normal.
Figure 7: UK Rainfall (relative) for December 2024
Despite the low precipitation, sunshine levels were also much lower than expected in Hereford and also the whole of the UK (Figure 8).

Never had much luck growing strawberries - most of the produce being eaten by birds, slugs, snails and rodents. I often find woodlice in and around damaged fruits but I suspect they are just scavenging on damaged berries.
Past failures are not, however, going to stop me trying again (note to myself: a fool is someone who keeps repeating his mistakes while expecting a different outcome). This time I'm going to create a wall of strawberry plants hoping the height above ground will deter at least some of the slugs and snails. I will need to add some protection against birds, probably netting of some sort. The other issue is irrigation to encourage juicy plump fruit. I will address this issue later.
My first job was to screw some tanalised timber battens to the south-east facing wall. Here I am using Worth Wall Planters bought quite a few years ago. They seem to be very similar, if not identical, to the current version. Other wall planters are available. It is possible to fix these planters to the wall using fewer battens (e.g. see here), but this arrangement is stronger and stabler.

The strawberry plants arrived a few weeks ago from D.T. Brown. They were immediately potted up in Fertile Fibre Potting Compost and hardened off in the polytunnel. There are 32 strawberry plants in this wall: 12 x Malling Champion, 10 x Summer Breeze (Snow), and 10 x Summer Breeze (Rose)

Work still to do: (i) attach net and support to deter birds, and (ii) fix up some form of automatic irrigation system.
Historical Note: We found the W. Earp & Son enamelled sign in the cellar. It is not a reference to Wyatt Earp (of OK Corral Fame) but to the lesser known Willam Earp, a nurseryman, seedsman and florist who business was in the adjoining street.
It was a nice day and we had nothing in particular on; note that is not the same as having nothing to do! Bluebells were out in Surrey ...

We had planned on having lunch at the Hop Pocket, but a wrong turning meant a change of plan and a delayed lunch at the National Trust's Brockhampton Estate. The catering facilities are somewhat basic but we were able to enjoy the curried cauliflower pasty with a cup of tea, returning later for an ice cream.

November - the ninth month (novem = nine) in the 10-month Roman calendar which became the eleventh month when January and February were added for the Julian and Gregorian calendars.
The selected photo for November 2024 shows a wintry scene on the 19th day of the month. The snow melted slowly over the following three days as the weather turned colder with subzero overnight temperatures (Figure 1).

November's weather stats from our garden-based Davis Weather Station are summarised in the table below. Storm Bert (23rd/24th) brought strong winds and plenty of rain (see Table).
The first two weeks were mild (mean daily temperature 〜 10 ℃) and dry - the seemingly constant grey skies gave only rare glimpses of the sun (Figure 1 and Figure 2). The next two weeks were colder (mean daily temperature 〜 5-6 ℃) and wetter (>90% of the month's rain) yet just as lacking in sunshine (Figure 1 and Figure 2). The mildest day of the month was the 30th (mean temperature 〜 13 ℃) and this mildness would carry over into December.
Figure 1: Min/Max Daily Temperatures for November 2024
Figure 2: Daily Rainfall and Sunshine Data for November 2024
Looking back over the past five Novembers (2020 - 2024), it is clear the weather for November 2024 was typical for this month - at least based on the most recent weather data. We can expect a few frosts (around four or five) even despite the generally mild temperatures (Figure 3). The mild temperatures are the result of dull grey cloudy skies so, unfortunately, sunshine is often in short supply. While precipitation needs clouds, not all clouds are rain clouds; consequently, rainfall in November can be highly variable (c.f. 2021 and 2022, Figure 4). Storms are a feature of November, hence the wind speeds are often high (Figure 4).
Figure 3: Temperature Data for November (2020 - 2024)
Figure 4: Rain, Wind & Sunshine Trends for November (2020 - 2024)
The following three figures come from the UK Met Office's monthly report for November 2024. Figure 5 shows November's mean temperature was similar to the 1991-2020 average for most of the UK except for a few western locations where the temperature was above average. Herefordshire's monthly temperature was close to the 30-year mean (1991-2020) in general agreement with the temperature data from our backyard weather station (Figure 3).
Figure 5: UK Mean Temperature Anomalies for November 2024
According to Figure 6, Herefordshire's rainfall in November 2024 was close to average except for the south of the county where the rainfall was higher than normal. Our weather station data (Figure 4) indicates that Hereford was in the wetter part of the county.
Figure 6: UK Rainfall (relative) for November 2024
Finally, in Figure 7, we can see that Herefordshire was relatively sunny compared with the bordering counties even though sunshine levels overall were only average. Data from our garden weather station (Figure 4) indicated sunshine levels were probably lower than average.

Storm Bert (22 Nov to 25 Nov 2024) brought lots of rain and some low-lying areas (i.e. flood plains) were flooded. The 'lake' below (Photo 11) is, in fact, the rugby pitches of Hereford RFC which regularly flood in winter due to their proximity to the River Wye.

My sampling site would have looked like a lake with no discernible evidence for a brook or stream.
