Tomato Test and Some Cold Nights

Since that lovely sunny warm Easter spell of weather it's gone rapidly downhill. Night time temperatures especially have been below average for late April with the thermometer falling into the 3°C (37°F) mark too regularly for my liking. As you can see from my weather station output we've had three very chilly nights over the last week.
There's are rumours that we might be set for something even colder over the May Day Bank Holiday weekend with temperatures falling to freezing as a cold northerly wind sets up. Far too much to expect two Bank Holidays in a row with good weather.
Forecast from Netweather.tv
I reckon the cold nights are slowing down the progress of seedlings in the greenhouse. One of the reasons I delay sowing our tomato seeds is that I'd rather they avoided these cold nights but my plan isn't working very well this year.

However, I did notice that in the pot that contained our dead nectarine tree there was a tomato seedling. This must have germinated from one of last year tomatoes that accidentally fell into the soil. I noticed the seedling a few weeks ago and over the cold nights, including some very frosty ones a few weeks ago, this young tomato plant remained unprotected. 
In some ways it must be as far on as possible for a tomato plant in the greenhouse, having germinated as soon as conditions allowed. Of course I've no idea what the variety is. It's likely to have come from an F1 plant so it's unlikely to produce true to variety. I still decided to give it a bit of TLC and potted it up into a decent size pot with the intention of growing it on to see how early it might produce some ripe tomatoes of one kind or another. I'll be interested to see how far behind my other tomato plants are at producing their first ripe tomatoes.
As you can see it's got quite a head start on my tomato seeds sown on 15 April which are almost ready for pricking out into pots.

Another Record - Lovely Easter Weather

Easter Sunday continued the spell of very warm weather for April becoming the warmest day of the year as the temperature hit 24.6°C or 76.3°F also making it the third warmest April day I've recorded in ten years.
Temperature Records 19-21 April 2019
However, there's been a reminder in the overnight temperatures that it's still only April, as the temperatures dipped to around 4°C or 39°F. I've taken the precaution of covering up tomato seedlings in the greenhouse to give them as much protection as possible against the cold overnight conditions.

It's difficult to believe how cold it was only a week ago when we had those very keen frosts which damaged the kiwi Issai that we had just planted out on the plot.
Kiwi - Issai (Frost Damage)
I'm hopeful it will make a full recovery as it had been growing outside at home so it should be accustomed to cold conditions. Easter Monday looks to be the last day of the warm spell of weather as Tuesday heralds a return to more normal temperatures and maybe some rain for a very dry allotment and garden.

Warmest Day Again - Rain Required!

Saturday took over as the warmest day of the year as the afternoon temperature reached 23.9°C or 75.0°F. The warm days have been very welcome but with lots of media hype around the spell of warm weather it's not been such a brilliant month for gardeners. The average temperature for April up until Saturday is 7.7°C (45.9°F) making it the third coldest April since 2010 with only 2012 and 2013 colder at this late stage in the month.
Temperature & Rainfall Records 22-March - 21 April 2019
Worryingly we've had to start watering on the allotment. As you can see from the chart above we've had virtually no rainfall in the last 4 weeks. Normally we'd expect around 50 mm of rainfall over a four week period rather than the 3mm we have actually recorded.
Rainfall in 2019 has been on the low side in any case with January and February having below average rainfall. March began with two wet weeks but since then nothing of any use for the allotment.
Rainfall Records for 2019
The current spell of warm weather is forecast to break down following Easter Monday with a more changeably outlook to follow. A decent rainy day would be most welcome at the allotment.

Warmest Day of the Year

How unusual to have some decent weather over a holiday period when Good Friday turned out to be a lovely sunny day with the afternoon temperature reaching 22.2°C (72.0°F) making it the warmest day of the year. Coincidently, 19th April broke the same record last year with a temperature of 28.8°C (83.8°F) the hottest April day I've recorded.
The weather is forecast to remain sunny and warm over the Easter period so it's possible that warmest day of the year record won't last very long.

Our resident blackbirds often take a bath in our pond. They have a regular spot for this in one of the shallower areas of the pond. 
They don't expect our summerhouse to be occupied but it was on Friday afternoon, as we enjoyed an afternoon cup of coffee this female blackbird arrived for her afternoon dip. She considered if it was safe enough for her to risk taking a dip for a short while as she eyed us suspiciously before deciding what the heck and went for it anyway.

Mid April Birds Eye View of the Plot

A look around the plot from above. At least now there is a little bit of green appearing on the plot as our fruit trees start to leaf up.

Plum Blossom - A Cold Case

I think, fingers crossed, that we've seen the back of the cold weather. A run of five consecutive nights of below freezing temperatures in April is the longest we've had in my ten years of weather records. It started me looking back at the previous spell of cold weather in April which occurred back in 2013.
April Minimum Temperature 2010 - 2019
The minimum April temperatures are shown in the table above and are colour coordinated from warmest in darkest red through to coldest in darker blue. The last spell of cold April weather was in 2013 only that came earlier in the month. I checked back through our harvesting records and found that 2013 wasn't a bad year for our plums. I'm concerned that this year's plum crop will be affected by the frosty nights whilst the trees have been in flower.
Details of Plum Harvest in 2013
A total of almost 41kg was a good crop so I initially thought that a cold start to April did little to reduce the plum crop. My hopes were raised a little bit that the cold nights wouldn't have damaged the plum blossom and we were still in with a chance of a good harvest. I wondered if I'd made any blog post comments at the time regarding the blossom and the effects of any frost. First of all I found this post from early April 2013.
Archive Blog Post Early April 2013
The difference in 2013 was that we hadn't had any mild weather through February and March. and everything was still in winter mode rather than being drawn into spring mode during winter only to be returned to winter once spring arrived which is what has happened this year. I carried on looking through a few more posts from April 2013. I found this post.
Archive Blog Post Late April 2013
In April 2013 when we had a cold and frosty start to April the plum and greengage blossom wasn’t damaged by the frost because it wasn't out and didn't come out for another couple of weeks after the frosts. I've decided we are just going to have to wait and see if the frost this year has caused any damage to the cherry, pear, greengage and plum blossom. Our apples are just coming into flower at the allotment so hopefully they won't have been damaged by the frosts.

Cold Spell Goes On!

We've decided not to visit the allotment over the weekend. We spent a few cold days there last week and we've decided to hold off doing any more planting until the cold spell of weather breaks. It's now becoming a rather prolonged cold spell although the early part of next week is forecast to see temperatures rising to more normal levels for the middle of April.
The average monthly temperatures for the year make interesting reading, although perhaps not if you are a gardener. April's average temperature is now lower than both March and February. We are still waiting for an April day to be warmer than the warmest days in February and March too. Spring temperatures are heading in the wrong direction at the moment and getting colder rather than warmer.

The cold frame was covered with some fleece to give some protection from the cold and to keep the blackbirds out as they enjoy digging around in the damp compost. 
However, in the open garden there is not that much we can do to protect plants from the cold nights. We've got a couple of pieris and the new leaves that should be a lovely bright red colour have been turned into frost burnt brown.
If we get some sunshine today to warm up the greenhouse a little bit, I'll start sowing some tomato seeds. They'll be grown on for a week or more in our indoor propagator and hopefully by the time they've germinated temperatures will have warmed up enough for them to be safely moved into the greenhouse to grow on.

Record Cold For April!

I posted yesterday that we might not be finished with frosty nights and it turned out to be correct. Never mind when in April it happened as early Saturday morning produced the coldest April temperature in ten years as the thermometer fell to -2.6°C or 27.3°F.
Temperature Records 11-13 April 2019
We can often go through April without a frost so three nights in a row is unusual especially as we are approaching the middle of the month. April should gradually be getting warmer not colder.

I had a quick check around the greenhouse and cold frame and everything seems to have survived okay. I didn't cover these lettuce seedlings last night (I forgot) but they look to have survived. 
Mixed Lettuce Varieties
I know from recording greenhouse temperature there's not a great deal of difference between greenhouse and outside temperature on cold nights. Everything looked to have made it through the cold in the cold frame too. My only concern was for some cauliflower plants purchased last week but they looked fine this morning.
Cauliflower - All Year Round
It appears that our young plants at home have survived the frost but there no way of knowing what damage has been done to any fruit blossom. At home we have apple, pear and cherry blossom out. You may be wondering about how our tomato plants have survived and the answer is they've done alright still tucked up in their seed packets. Hopefully, the cold nights should relent in the early part of next week and some serious seed sowing can begin.

Coldest Late Spring Morning

As if yesterday morning wasn't cold enough, early Friday morning became the coldest morning this late into spring I've recorded when the temperature fell to -1.9°C or28.6°F.
Temperature Records 10-12 April 2019
The coldest April morning I've recorded since 2010 was 07 April 2013 when the temperature dropped to -2.4°C (27.7°F) and Friday now becomes the second coldest April morning in 10 years.

We had a quick check around the allotment on Thursday afternoon to see if we could spot any damage from Thursday morning's frost. Sue noticed that some of the leaves on our newly transplanted kiwi Issai had some frost damage.
Other than that we couldn't see any other damage although we will have to wait and see how much damage these keen late frosts have done to the plum, greengage, pear and cherry blossom.

Our early Casablanca potatoes in the plot greenhouse looked well and had escaped any damage.
Before we left I took the precaution of covering them with some environmesh just in case we had another frosty night.
I'm glad I did now. I'm not sure we've finished with the frosty nights just yet!

Below Zero!

The temperature fell to -0.4°C (31.3°F) in the early hours of Thursday morning. 
Temperature Records 09-11 April 2019
During the last few days it's been chilly by day, with temperatures below average, but we really could have done without a frosty morning. On the plot the pear and plum trees are in full flower and a frost will most likely have damaged the blossom reducing the potential crop.
Cherry - Stella
In the garden at home our cherry tree is also in blossom so this rather late frost has come at a particularly unwelcome time. For the record the last below zero temperature in April was on 10 April 2016  falling to -0.6°C or 30.9°F.

Poor Weather for Gardeners

The weather models aren't predicting any good growing weather for the next week to ten days. All the models are suggesting that a Scandinavian high pressure will control our weather over this period, bringing us north to north easterly winds.


As you can see from my April weather station records this has been the case for the last six days. Daytime temperatures have remained below average for early April but because we've had cloudy conditions night time temperatures have been around average or slightly above.
Skies have remained cloudy for most of the day. On Monday there were a few fleeting glimpses of sunshine and Tuesday morning has started a little bit brighter. The big gardening decision is whether to start sowing any seeds. At the moment I'm contemplating sowing some brassica seeds in the greenhouse but I'm going to leave sowing our carrot and parsnip seeds for some warmer weather. Any sunshine will soon lift the greenhouse temperature, but I want to avoid sowing carrots and parsnips into cold ground at the allotment.
These tulips provided some welcome colour on the allotment on a cold dull April afternoon.

Holding Back on Sowing & Planting

I'm not in any rush to get any more sowing or planting done down on the allotment. After all the temptation, with a very mild February and a mild March, now the main growing season is underway it's turned colder. I think the ground could do to warm up a little bit more before we think about sowing any seeds outside.
2019 Temperature Records

It's been a cold start to April, with the average temperature for the month now the same as February's and below March. At the moment the forecast suggests a couple of milder days before cooler weather returns early next week. Hopefully, we will get the remainder of our onion sets and shallots planted out over the next couple of days, but I'll see how the weather turns out before getting more of our potatoes planted.
Our cold frame is now full, mostly with soft fruit, plants are either hardening off or growing on before they are planted out at the allotment. This year we are replacing our main strawberry bed and planting up a new row of raspberries. Our new raspberry canes are still in the greenhouse as the cold frame is full.
On a bitterly cold day last week, we set about preparing for our new raspberries. The supports are set up and the ground covered with weed control fabric and wood chippings so once the canes have sprouted we will be able to get them planted.

It wasn't all gardening though, we found time to photograph a steam charter train at Woodlesford station. The train was travelling from Carnforth to the Wensleydale Railway.
Hopefully, the weather will be better than forecast next week, and we'll be able to get some planting done at the allotment.

Planting Starts in a Month of Two Halves

I think I might overuse the term "a month of two halves" but in the case of this March it has been very true weather wise. The first two weeks of March were wet and windy.
Rainfall March 2019 
Up until the 18 March we didn't get a dry day. Some days it was only a little bit of drizzle, or a very light shower, but it rained in one form or another for the first 18 days of the month. Then nothing for the rest of the month, however there was enough rain in the first half of the month to make it the third wettest March in the last 10 years.
March Rainfall 2010 - 2019
That said, I think the windy weather for the first couple of weeks was worse than the rain. As areas of low pressure crossed the country, one after another, from west to east we were battered by strong winds every day. I think the two tables below give some idea of the scale of the windy weather with March 2019 third equal in my windiest months table.

All this meant that trips to the allotment went on hold, save for a couple of quick visits to harvest some fresh vegetables.
All that good progress we'd made in February seemed to be slipping away as we waited for the weather to improve. Eventually, the wind abated and the rain stopped, and the last couple of weeks of the month were pretty decent with a few warm sunny days. The 20th of the month took over as the warmest day of the year so far, when the temperature reached 20.3°C or 68.5°F. On the plot our plums and greengages started to flower.
As the last of the overwintering root vegetables were dug up, the first of this year's were planted. First early potatoes Rocket, Casablanca and Athlete have all been planted and we're hoping to make a comparison to see which of the varieties performs best for us. Rocket have been planted, almost as a sacrificial crop, in a bed cleared of weeds and brambles over winter so it will be interesting to see how they get on. We've also managed to plant our early brassicas, almost a month earlier than last year, so hopefully they'll be alright and won't suffer any nights that are too cold for them.
 Early Brassicas, Cabbage - Regency, Cauliflower - Helsinki and Calabrese - Aquiles
Finally a word about the temperature through March. It's turned out to be a mild March coming in third place over the last 10 years.
March Temperatures 2010 - 2019
Despite a rather poor first couple of weeks to March, we've certainly not fallen behind in our allotment planting and sowing. I should admit to not doing all that much sowing in March anyway, preferring to do the bulk of our seed sowing in April when the temperatures are a little bit higher and the soil temperature a little more conducive to seed germination.
