Where's Summer Gone

We haven’t visited the plot for the last couple of days as the weather hasn’t been up to much. Whilst much of the country has suffered flash flooding and wet weather we’ve somehow managed to miss nearly all the rain. We have had a little bit of rain on Saturday morning maybe just enough to avoid watering the plot for a couple of days.

I always find it a bit odd when there’s a need to water the plot when the weather is cold and damp. Still the forecast is for more rain over the weekend so we may be able to spend more time harvesting and doing a few other jobs that need to be tackled but have been put on hold to allow us to keep the plot watered.

Back in spring when I sowed our tomato seeds one of the packets contained a rogue seed which not only germinated before the tomato seeds but grew much quicker.

Intrigued to find out what this seedling was it was potted on and it’s been growing slowly in the greenhouse all summer.

It needed potting on weeks ago but I’ve never got round to doing it. It’s now doing its best to make me feel guilty by flowering. I really will have to find time to move it on into a larger pot.

22 July 2017

I had my suspicions when it germinated that it might have been a Morning Glory seedling, in which case it probably didn't arrive in the seed packet but somehow a seed from one of our old plants must have got into the compost. At least I didn’t throw it away in April when it germinated amongst the tomato seeds.

What Storms!

Social media and newspapers have been full of stories of potential and actual thunderstorms all around the country. Some places have suffered flash flooding. So, it was with bated breath that we awaited our turn. We didn't want the flash flooding or the torrential downpour just some decent steady rainfall to water the garden and allotment. I give you yesterday's rainfall details.

Rainfall Details for 19 July 2017

We had to wait until almost midnight for a few spots of rain. To be honest it was a muggy day and late in the afternoon and into the evening it wouldn't have been much of a surprise if we'd had a storm but whatever heavy rain was around passed us by.

As you will be aware if you follow either mine or Sue's blog we've refurbished the perennial flower bed on the allotment. The roses in particular received some rough treatment as we tried to remove the couch grass and bindweed from around their roots. I thought that we had lost up to three of the five roses planted in this border 10 years ago. However, Baroness Rothschild has survived and is now flowering once again.

Rose - Baroness Rothschild

Elmshorn and Jacqueline du Pre have survived the refurbishment and are growing well. One called Evelyn has a few green leaves and we are hoping it will survive whilst the final rose Golden Wings is showing no signs of life at all and will need to be replaced.

Blue Sky All Day

Tuesday was a lovely summer's day with blue skies from dawn until dusk and pretty warm in the afternoon as the temperature made it up to 25.8°C or 78.4°F.

On Sunday we made some provisional plans for sowing some carrots and Pak Choi. One small bed was cleared of some seeded rocket and salad leaves but instead of digging over the ground it was given a good watering.

I reckon the size of the bed is about 10 sq/m and I tipped 10 watering cans of water over the bed. Each can contained 10 litres of water. By my calculation that should be equivalent to 10mm (0.4in) of rainfall. At the time it seemed a bit over the top but the water disappeared into the soil and didn't leave any standing on the surface. I felt certain my rough depth of rainfall calculation was correct. Working in metric units the answer definitely had a one in it, just a case of units and had I got the decimal point in the correct place. We decided to leave the bed overnight and see if it would dig over on Monday afternoon when we visited the plot.

When we arrived on Monday afternoon things didn't look too promising. The sunshine had certainly dried out the top of the soil and it certainly didn't look like it had been watered copiously the day before. The sunshine hadn't baked the surface of the soil into a hard surface which was a positive sign. But then the intention was that there would still be some moisture underneath and the bed would dig over using our cultivator.

I could tell as soon as the cultivator started working its way through the soil that the watering had worked a treat and the bed dug over very easily leaving a tilth that we could sow directly into.

We managed to sow Pak Choi and a row of late carrots in the bed above. There will be some room for a few short rows of radish and one or two lettuce plants at a later date. Unless the dry spell ends though we will have to keep the bed well watered if we want the seeds to germinate. It's amazing how many cans of water are needed to replicate a decent day's rainfall.

Still No Rain

It's been a few days since I last did a blog post. The weather hasn't been very exciting, some sunny days and some cloudy, with around average temperatures for the middle of July. The only thing we haven't had is any decent rainfall.

Rainfall Record Last 4 weeks

We had enough to dampen the surface last week but the only rainfall of any use as far as the allotment and garden goes was at the end of June. The dry weather is starting to have consequences at the allotment.

Our Japanese Wineberry appears to have succumbed to the dry conditions and as far as we can make out has died. We both think we have given it some water as we've gone around the plot watering but maybe we are mistaken. It's a blow as it was only planted a couple of years ago and was beginning to be rather productive.

I've a little bit of software that works with the data from my weather station to estimate how much evaporation takes place each day based on temperature, wind speed and solar radiation.

I've highlighted the two interesting columns. Whilst the rainfall for the month is 7.1mm (0.28in) evaporation is a whopping 42.0mm or 1.65in. Now I'm sure there's some errors in the way the evaporation is calculated but it shows the trend of how much moisture the soil has lost compared to the rainfall we've had.

Coldest July Day?

Tuesday's weather didn't delivery on the rainfall front as despite another seemingly wet day we finished up with just 5.0mm (0.2in) of rainfall nothing like as much as was suggested in the forecast. Still, I suppose it's better than nothing but I don't think it will have done much to alleviate the dry conditions in the garden and allotment.

Temperature & Rainfall Records for 11 July 2017

However, with a daytime high temperature of just 13.3°C (55.9°F) Tuesday was the coolest July day I've recorded taking over from the 20 July 2012 when the temperature reached only 13.8°C or 56.8°F.

On the plot I'd like to trim back a laurel hedge but I've noticed that we've still got some young birds about in the garden so I'll leave any trimming back until next month when the birds will have finished nesting.

This young goldfinch was checking out the sunflower hearts in the bird feeder at home early on Wednesday morning.

I Like The Look Of This Forecast

I wouldn't normally say that I like the look of a weather forecast that's for a thoroughly wet day but the garden and allotment really need a good soaking. Maybe today they will get one.

After a lovely sunny weekend Monday turned out to be one of those days I've mentioned lots of times in my posts this year.

Sunday Afternoon On The Allotment

Monday was a day of drizzle and at times short showery bursts amounting to 1.8mm (0.07in) of rainfall all day certainly no use in watering the garden or allotment.

As you can see from the table, above right, the only rainfall we've had in the last four weeks fell almost two weeks ago now. That fell on already very dry ground and soon seemed to disappear leaving the ground once again bone dry. Cultivating the ground for sowing and planting some summer crops had become very difficult. We'd like to get some ground prepared for a late sowing of peas not to mention some late salad crops and a variety of cut flower seeds.

So, a good wet day would be very useful and save us time having to water the allotment. The forecast for the next couple of weeks doesn't have much rain in it which is all the more reason for hoping that today's forecast turns out to be correct. At the moment 09:30 it's about right as we've had our first 2.2mm (0.09in) of rainfall.

A Perfect Summer's Day

Saturday was a perfect summer's day, sunny and pleasantly warm but not too hot. A day for a bit of steady harvesting and photography on the plot.

Most strenuous job of the afternoon was lifting a few potatoes.

Followed by a coffee break.

Here's an early July tour of plot 41.

Hot and Sultry

The weather forecast was correct for Thursday as it turned out to be hot and sultry as the temperature reached 28.4°C (83.1°F) in the afternoon. The afternoon had the feeling that a storm was brewing up.

Temperature & Solar Radiation Records for 06 July 2017

However, we missed out on any rainfall and we missed any thunderstorms that were around. On occasions the sky clouded over as though we would be getting a storm at any moment.

In the late afternoon we had a few rumbles of thunder as a storm passed to the south of the allotments.

As the storm passed I was watering the plot. I thought that I was maybe wasting my time and that a thunderstorm would do the job for me. As it turned out it was just as well I continued watering as the storm passed by without shedding a drop of rain. Rain is becoming a precious commodity on the allotment and in the garden.
