May: full speed ahead in the greenhouse!

May is a such busy and exciting time in the greenhouse and polytunnel.  Plants are in all stages of creation, from sweetcorn seeds in the heated propagator, to young tomato plants planted in the borders.

Working on seed sowing, pricking out, and potting on, especially when it’s raining outside, is pure joy.  After no rain all through April, this last week of regular rain is very welcome, as is the change to frost-free nights.    Of course there might still be frosts until June, so it’s not yet time to put away the horticultural fleece and bubble wrap that covers the greenhouse plants on cold nights.

Nicotiana, sunflowers, cosmos, mitzuna, cornflowers, and lettuce. Although the cornflowers, mizuna and lettuce are frost hardy, I keep them in the greenhouse until they’ve grown into big enough plants to survive attack by slugs and snails!

Another radio moment – explaining the importance of peat free compost

Considering the record temperatures we’ve had this week (32.5C), I’d been meaning to finally write a post about the two water-saving automatic drip watering systems that I use, and the bulk rainwater storage in my garden… I must do that.   Then yesterday we had record rainfall – about 2 inches in half an hour I think.  O tempora, o mores!

One thing that would help control climate change and reduce extreme weather events like we’ve experienced in the last few days is if the gardening industry would stop taking peat from peat bogs.  There is more carbon locked up in peat bogs than in forests in the northern hemisphere, and yet uncaring companies continue to dig up UK peat bogs to put the peat into plastic bags to flog to gardeners as ‘compost’.   Even though they signed a voluntary agreement to stop doing this by 2020!  Once dug up, the peat-based compost reacts with oxygen, degrades into useless dust, and releases its stored carbon.  Never buy compost unless it clearly states on the bag that it is Peat Free.

Yesterday I was asked by presenter Kate Clark to talk about peat free compost on BBC Radio Gloucestershire.

Listen at BBC Sounds (1 hour 12 minutes into the programme) or when that expires, which sadly it will do in 30 days because of the music in the show, you can use this backup audio file.

We also talked about Bisley Community Composting Scheme, which I’ve been a voluntary director of for the last couple of years.  At Bisley we produce over seventy tons a year of excellent peat free compost, just from the garden waste of Bisley village.   You can come and buy it in bags (4 x 30 litre bags of sieved compost for £10) or collect bulk unsieved compost in exchange for a donation.  See website link above for details of how and when to visit.

My moment on Radio 4’s Gardeners’ Question Time (promoting the virtues of compost toilets)

Yesterday’s edition of Gardeners’ Question Time -Sunday 19th January 2020 – satisfied one of my lifetime ambitions – I was on the programme, asking a question!   The show was recorded in Nailsworth in December, and once I wrote my question on the piece of paper handed to me at the door, I had a good feeling that it would be chosen.  The question was:

“I have a compost toilet in my garden.  It saves tens of thousands of litres of water a year, and makes wonderful compost.  Do the panel members have compost toilets in their gardens, and if not, why not?”

The producer chose it as the first question of the show.   You can hear it here (at 4 mintues 47 seconds into the show)

The panel members didn’t really know much about compost toilets, but at least they were positive about the idea.  Hopefully this bit of exposure for compost toilets on Radio 4 will set more people thinking about them, and lead to more people making their own.

My compost toilet sits at the end of my garden.  I built it in the autumn of 2016, and after 3 years of use I couldn’t be keener on it – I love it and I think that everyone who has the space should have one.  One of these days I’ll write a detailed step by step article about how I made it and how it works.

This was my second attempt at getting onto Gardeners’ Question Time.  I went to a recording of the show at the Royal Agricultural College in Cirencester about 3 years ago, but didn’t have my question selected that time (“Why is Glyphosate/Roundup weedkiller not banned in gardens?”  Too controversial I expect).

Here’s  a photo from the Nailsworth recording in December 2019

Recording of Gardeners' Question Time, Nailsworth 17th December 2019, broadcast 19th January 2020.

They actually recorded two shows in Nailsworth that evening – the second is to be broadcast on 2nd February (I guess they needed to cover the Christmas and New Year gap).    Each time I’ve been to a recording of GQT, I’ve been really impressed with the incredible skill of the chairman in linking everything together so smoothly and coordinating the panel and questioners’ contributions in such a good natured way.  This time it was Peter Gibbs, last time it was Eric Robson.  Both of them such excellent broadcasters.  The panelists were good too of course.  It was a shame that Bob Flowerdew wasn’t on the panel for the compost toilet question – I’m sure he would have had plenty of informed comment on the subject.  Pippa Greenwood asked (probably not seriously) if I would design a compost toilet for her garden… if you’re reading this, Pippa, just get in touch 🙂

One surprising thing about the show is that they don’t record any extra questions that don’t get broadcast.  They choose just the right number of questions, and the show goes out on air pretty much as it was live, no doubt with a few very subtle edits to keep within the overall time limit.

Now my dream would be for Radio 4 to get in touch with me to present a 30 minute programme all about compost toilets 🙂  There are quite a few around in Stroud, and promoting them is a real passion with me…

Start of the growing season

Like the garden, I’ve been fairly dormant since late autumn.  I think I’m very lucky that I don’t have to rely on gardening for my living all year round – I have other types of work which don’t involve braving the winter weather.

Anyway, things are well and truly bursting into life outside now, I’ve resumed gardening work again this week, and I’ve sown my first batch of seeds in my greenhouse – mostly annual flowers, plus a few edibles.   Such a lovely time of year, having the whole of the spring and summer still ahead of us!

Invasion of the Ivy Bees

A bee or not a bee, that is the question

When about a thousand bee/wasp creatures came to live in my garden polytunnel a couple of weeks ago, I emailed our local permaculture group members for help identifying them.  The bees/wasps were feeding on the split tomatoes by day, and at night were going to sleep in clumps on the floor.  The polytunnel doors were wide open, but they showed no signs of planning to leave.

The mystery of what they were was soon solved.  Someone else had recently had the same thing happen in their polytunnel, and the insects had been identified as Ivy Bees.  These are a fairly new species to us, first seen in the UK in 2001.  They hatch out in the autumn and feed on the ivy which is flowering at that time.   When I looked closely at the ivy in my garden, lo and behold, more such stripey bees were indeed buzzing round the ivy flowers.

I was told that the Ivy Bees were docile, only stinging under very extreme provocation, which seems to be correct as despite having hundreds buzzing round me when picking tomatoes, I haven’t been stung.  They are fairly short-lived, and sadly most of mine have now died (in heaps on the polytunnel floor!).   Apparently they lay their eggs in burrows in the ground, with many females making burrows close to each other.

I wonder if they have made their burrows inside the polytunnel?  Perhaps I will see their descendants this time next year.  I can’t help thinking that they’d be better off living outside, taking nectar from the Ivy flowers.  After all, they aren’t called Polytunnel or Split Tomato Bees.


Austrian Scythes

Grass too long in your orchard?   I finally got a chance to try out an Austrian Scythe recently, having heard about them for several years.   They’ve become popular as they are lighter than the traditional English scythe.  I was impressed, much easier to use than I expected, even for a beginner, and far more effective than the petrol strimmer would have been!

Potato Day and Stroud Community Seed Bank

There’s very little gardening to be done in January other than pruning fruit trees, but one very important task is thinking about the seeds that will be needed in the coming season.   So I’m getting out my box of left-over and saved seeds, and checking what I have, and what seeds I’ll need to buy or swap to be ready for the growing year ahead.

There’s a great event coming up in Stroud that will help with this.  The annual Stroud Potato Day (Saturday 3 Feb, 10 till 2.30, Merrywalks Shopping Centre)  is an un-missable opportunity to buy seed potatoes.  They have a huge selection, and you can buy large or small quantities, even just one or two of each type if that’s what you want to do – great for testing potato varieties you’ve not grown before.

Stroud Potato Day 2018 and Stroud Community Seed Bank

This year, Stroud Community Seed Bank will also be at the Potato Day, offering members of the public the chance to have a share of the seeds lovingly grown, saved, and packaged by the volunteer members of this pioneering local group.  You can get old favourites,  heritage varieties, rarities, and local varieties.  For example,  Cherokee Trail of Tears beans, Jane’s Flat White Beans, Oskar peas, Purple Ukrainian, Tangerella, and Hawkwood Cherry Tomatoes, Thrupp Parsnip and no end of flowers.   All available for a donation of 50p or £1 per packet.   More info about the Seed Bank on their website, and their Facebook page, and you can download the full Stroud Community Seedbank Catalogue here.

Packet of Stroud Community Seed Bank BeansThere are also Seed Swap events coming up in Stroud: at the Stroud Valleys Project shop in Threadneedle Street on Saturday 24th Feb 10.30 – 1pm, and at a Stroud Community Seed Bank filmnight at Lansdown Hall 7pm, Friday 2nd March.    The Seed Bank’s seeds will also be available at both events, and at the Down To Earth stall at Stroud Farmers Market on Saturday 27th January.

And if you’re itching to get sowing, what seeds can you plant at this time of year?  It’s still very early, but I’ll be sowing some onions seeds in trays in a cold greenhouse next week, and starting a few early tomatoes on a widowsill in early Feb, when you can also make outdoor sowings of broad beans.  Apart from that, almost all seed sowing takes place in March and April onwards, so there’s still plenty of time to think about what seeds to sow this Spring, and get out to a seedy local event.


(Blight) resistance is not useless!

It’s been a pretty dreadful summer for blight on outdoor tomatoes – there was such a lot of rain all through August, and blight thrives in damp conditions.  So it was good timing for my trial of a new blight resistant tomato – Mountain Magic.   They did really well – when other outdoor tomato plants have long-since died a horrible death, the Mountain Magic plants are still thriving and perfectly healthy!    Their tomatoes have a pretty good flavour too, so I’ll definitely be growing more Mountain Magic plants in future years, for customers who can only grow their tomato plants outside.

In a dryish summer, ‘normal’ tomato plants can fruit well outside in a warm sheltered spot such as against a south-facing wall.  But on the basis of this year’s experiment, I think it’s well worth growing a mix of Mountain Magic and other tomato varieties, in case the blight strikes early as it did this year.   Fifty percent Mountain Magic would probably be my recommendation.

If you grow your tomatoes in a greenhouse or polytunnel, of course you don’t need to worry about blight, as indoor tomatoes are rarely affected (their leaves stay dry, so the blight spores don’t multiply on them).

Here’s looking forward to the introduction of other blight resistant outdoor tomato varieties –  a cherry tomato would be nice, as Mountain Magic produce small-ish full sized fruits, later to ripen than cherry-sized fruits would be.    If you’re wondering about blight resistant potatoes, the family of Sarpo potatoes, such as Sarpo Mira, are pretty good in my experience – mine are still healthy and flourishing in mid-September after a very wet summer… and they’ve grown some really massive potatoes thanks to all the rain!

Wading and weeding

It’s not often that a gardening job involves something totally new to me, but recently I’ve been working in a large garden that is surrounded on all sides by water.   So on a couple of the recent hot days, I’ve been in waders in the river, weeding it, as the owner has a legal duty to keep the water course free of vegetation.   Luckily, the owner knows a lot about water plants, as I don’t!  I’d heard of water mint and water cress, but not water parsnip or water forget-me-not!

In my own garden and allotment, I’m doing much more conventional tasks for this time of year.  The biggest job is picking the soft fruit – I aim to get as many berries as possible into the freezer, to have with my morning muesli throughout the winter.

It’s a bumper year for redcurrants and blackcurrants.

Other than that, all the food plants are planted, and the work in the kitchen gardens has eased off, which gives me time to admire the newly extended border in my back garden, which is pleasingly crammed with flowers, including lots of nicotianas, clarkia, rudbeckias, penstemons and cornflowers grown from seed to fill up the new space.  Gardens are such heaven in June and July!
