Bolting Lettuces

It's time to ditch my windowsill grown lettuces
I returned from holiday to find lots of my lettuces have started to bolt. It's due to a combination of the recent heat, the longer daylength and my having too many lettuces growing to keep them thoroughly picked to their central core.

It's too late to save my pictured 'Amaze' lettuces. A quick nibble on a leaf showed they're too bitter for eating. As these are windowsill grown, I'm not going to save their seed - NAH has been most tolerant of my growing activities, but I think seeding lettuces in the bedroom might be beyond his limit!

Outside I'm keeping my non-bolted lettuces well picked and well watered and I've moved the potted ones to a much shadier part of the garden*. These measures should help prevent my remaining lettuces from doing what comes naturally. As soon as they start growing upwards then I'll have to decide which are going straight to the compost bin and if any are worth saving for seed. So far, Black Seeded Simpson, Freckles, Marveille de Quatre Saisons and the iceberg varieties are resisting the urge to bolt the most.

It's really too hot at the moment to sow their replacements (lettuce doesn't germinate well if soil temperatures are above 25oC), but I'm going to have a go at sowing some later in the day and keeping the seed trays in the coolest, shadiest part of the garden to let the seeds take advantage of the cooler nights. If this doesn't work, then I'll simply wait until next month to get my next batch of lettuces going. NB it's also time to sow a variety of non-lettuce leaves ready for late summer/autumn picking.

Have you found any particular lettuce varieties which are less reluctant to bolt? It would be great to compile a list of them for future reference :)

* = or you could use some netting to shade them if moving's not an option.

    I would love a list of these lettuces...I will also have to wait as we are still in the tropical weather zone right now.

      Hi Donna anything you and your fellow garden bloggers can do to add to the list would be great. I don't think there's much of a variety overlap between our sides of the pond? Or we do have an overlap, just different names!

    Red Salad Bowl hasn't been too bad for me. But it is also my favourite (love the colour on the plate) so it does tend to get well picked.
    It's so difficult to find the right balance between having too many plants and too few. After last year's wash out & slugfest, I've now gone for overproduction, so I'm having more wastage this year but at least we have not run out.

      You're quite right, I've just had a peek in my cold frame and both red and green salad bowl lettuces are still coming along nicely :)

    We are in our true July-August weather - close to 100 degrees every day so lettuce is out of the question.
    I'll plant kale and chard next month and buy lettuce at the farmer's market when it returns in the fall.

      Molly - welcome! We're in the middle of a heatwave (high 80s F) which is forecast to last for over a week. So lettuce may become out of the question for us too!

    I fell like my arms are dropping off from all the watering we are having to do, even so my little gems, which have been brilliant this year, are just bolting now. I also have a mystery iceberg type lettuce, a type I don't usually grow given to me by a lovely elderly Chinese speaking allotment neighbour which has been brilliant. Goodness knows what sort it is - she doesn't understand a word I say! I wonder whether it is the amount of lettuce I am eating that makes me so sleepy in the afternoon a la Flopsy Bunnies.

      Same here Colleen and I have raspberries, spuds and apples which are desperate for more. I spotted an opium lettuce amongst the Plant Heritage varieties on offer at Hampton Court. However, I have too many other varieties on the go, so resisted buying some!

    Our Tom Thumb lettuce finally went to seed, and a lot else has as well. It is the season to be thin on greens in this heat unless one has the proper place to grow them and has timing down to perfection. Now do I recall you grew Dazzle? Has that bolted?

    So we are eating green and purple wave mustards, some lettuce, scarlet kale, Bright Lights chard and bulls blood leaves. Sort of a harder leaf salad..so...good with a Caesar salad dressing or ranch. Shred leaves, remove stems. Add any fresh herbs. Garlic scape pesto perhaps )))

      Dazzle is just about hanginging in there - it's wanting to bolt, but the leaves are still sweet. I'm hoping that some rapid picking has stayed its execution.

      I've never really got on with chard, but it's such a good leaf to have on standby for all kinds of times when other leaves are in trouble. Perhaps I should sow some for emergencies...

That blue flower: A spring spotter's guide

Image
Spring is a prime time for blue flowers and my daily walks currently have several from the same plant family* lining the local footpaths. As I walked past the Donkey Field the other day, I overheard some children ask their parents** what the pictured blue flower was. It reminded me it's often mistaken for those other familial blues and this time was no different, as they said it was forget-me-not, instead of the green alkanet it actually is. As well as similar flowers, most of these plants are hairy in their nature, flower around the same time, and favour damp, shady places. Many of them are great for pollinators too, especially bees and this week's warm weather has certainly drawn them to these flowers. This makes it even more likely for these plants to be mistaken for each other and it's a great opportunity for me to put together a spotter's guide in case you find the same flowers on your outings. Staying with green alkanet, the key features which set it ...

Jack Go To Bed At Noon

Image
Last year this rather exotic looking flower appeared on mine and several other allotments for the first time. Having been stumped (again) by Mr Allotment Warden as to its identity, I rushed home to find out what it was. It's salsify, aka the marvellous Jack Go To Bed At Noon - named as such because its flowers always close by midday. Here you can see both open and closed flowers - making it seem even more exotic and alien than in the first picture. I think this must be the cultivated version because the flower in my Francis Rose Wild Flower Key looks exactly the same in form, but is bright yellow in colour and called meadow salsify . Its other common name is Goatsbeard, which must be a nod to the fantastic dandelion-like clock which forms the seed head. With 'parachutes' like those shown above, who knows how far our plotted plants came from. I rather like the photographic dissection of the seedhead found in this link . Salsify is edible: its lateral shoots and fl...

Red Nose Day - Gardening Jokes Anyone?

Image
The nation goes ever so slightly bonkers on Red Nose Day - hurrah! Previously, it's been very easy to join in - usually via a dress down day at work plus lots of people up to mad things at the station and in the office. Everyone smiling for once - it's a real feel good day and all in a good cause. This year's different - every day's a dress down day for me now - my friend L suggested yesterday that perhaps I could have a dress up day instead and whilst that's a good idea, I confess that ballgowns and tiaras don't really feature in my wardrobe: scruffy student's always been my favourite look. So my Red Nose Day contribution for this year is to compile a list of gardening related jokes. For each one (clean ones only please) you leave in the comments below, I'll make a donation of 50p to the cause. Here's a few for starters just to get you warmed up: Q Why do potatoes make good detectives? A Because they keep their eyes peeled. Q What did the grape...

Salad Days: Mastering Lettuce

Image
I've decided one of my salad challenges for this year is to grow as many lettuce varieties as I can, ready for the publication of my planned Factsheet* later on. The idea is to grow as many of the Tried and Trusted lettuce varieties last year's Salad Challengers helped compile, then provide a visual guide and as many lettuce facts as I can muster. So far I've found around half of those listed**. Then naturally whilst I was out searching - because such is the way with seeds - a number of other varieties found their way home too ;) A couple of weeks ago I sowed 22 varieties***. Just the simple act of sowing them has me intrigued. Why are some lettuce seeds black and others white****? They split into about half white to half black in my sample and as far as I can tell it's nothing to do with whether they're a type of cos, iceberg, or whatever. I sowed them indoors and popped them into a propagator on the windowsill. The soil's too cold outside for sowing ...

VPs VIPs: Derry Watkins of Special Plants

Image
Last week I had the pleasure of visiting Derry Watkins at her home, garden and nursery - the acclaimed Special Plants - just a few miles along the road from me. I first met Derry at one of her open garden days last year and was keen to find out more about her wonderful garden and running an independent nursery. She specialises in tender perennials and regularly goes on plant hunting trips to find new treasures, particularly in South Africa. As well as running Special Plants and opening her garden under the NGS scheme , Derry holds day courses at her nursery, hosts Special Tuesdays from April until September, lectures and has written a couple of books. How did you find your way from Connecticut to the UK? I'd started a biodynamic vegetable garden in Connecticut and we used to have people come along at weekends to help out. A particular young man turned up: he returned many times and at the end of the summer I married him. So it was all down to love? Isn't that the...

#mygardenrightnow: heading into summer with the Chelsea Fringe

Image
Ahhhhhh, that's better! I love walking through dewy grass in bare feet, not that there's much in the way of grass on my back lawn this weekend. My wild and woolly lawn has morphed into meadow of sorts this month, which even NAH admits looks attractive*. It's also proved a great source for my Flowers for mum project so far, yielding self-sown perennial cornflowers, lamb's ears, and lemon balm in addition to the blooms you can see. These originated from elsewhere in the garden, the ox-eye daisies must have blown in from the A350 nearby. * = he got very stroppy about the weeds aka self-sown foxgloves in the lawn one year, so he's come along a bit since then. Skimble's demanding to say hello to you too. He does enjoy the patio when it warms up. If the embedded video doesn't work try this link instead. The Nectaroscordum are a revelation. I planted the bulbs around 2 years ago, but it's only this year they've bloomed properly. The bee...

Make Use of Mildew

Image
On my garden patrol this morning I spotted some powdery mildew on a couple of my new Verbena bonariensis plants. I suppose it was almost inevitable as I prefer to grow my plants hard - this means no water for them unless they look absolutely desperate. This approach means plants root themselves more deeply and have a better chance of survival during spells of dry weather like we've had lately. However, it also means I run the risk of problems like today's, especially with any garden newbies planted late in the season. We've had a good drop of rain overnight, so this should help my plants survive. I'll mulch them later today to help lock in the moisture as it's water stress which encourages the mildew to take hold. I've also removed the infected leaves and sprayed the rest with a milky drink.* I'm also pleased to find there's a use for my infected leaves. Oliver Ellingham at Reading University has started a PhD - sponsored by the RHS - researchi...

The Resilient Garden

Image
  Part of Tom Massey's Resilient Garden at RHS Hampton Court I've been pondering VP Gardens a lot lately. Last year's drought conditions set me off initially, then our harsher than usual winter combined with this summer's flip and flop weather means the thinking continues. It's a huge topic which I freely admit I'm struggling to get my head around. Tom Massey's Resilient Garden  at Hampton Court recently  tackled this topic brilliantly and was a timely interlude which gave me much food for thought. There he encapsulated the detailed research he'd found which informed both his show garden and book of the same name. I think it's one of the most important show gardens I've ever seen. It's clear the way I garden needs to change so that I have my own resilient garden. I haven't worked out the exact details yet, but Tom's book plus a couple of others (see below), alongside the rainwater management handout from the show garden's  sponso...

The gloves NAH used to build the raised bed . The effects are L to R, top to bottom:  Original photo, Warhol, HDR, Green tint, B&W, Posterize, Boost, Cross process and Sepia Welcome to Shows of Hands - my Chelsea Fringe project for 2014! As you can see I've been having a bit of a play around in Pic Monkey for my first contribution. You're welcome to join in between now and 8th June 2014. The idea behind this year's project is to highlight the tool most precious to a gardener: their hands. How do I take part? It's simple. All you need to do is take a photo of hand(s) in a gardening context and then share it via your blog or other social media (such as Twitter or Facebook), then make sure I know you've done so. I've set up Mr Linky below for your blog contributions. The Chelsea Fringe photo on the right sidebar links to this post, so you can easily find it again when you're ready to add your contribution.

Testing Times: Tomatoes

Image
  I've run a couple of tomato trials this year. The first is a revisit of the biochar trial with Oxford University I attempted some years ago (with a different organisation this time), and the second is a trial of a water gadget called Plantsurge which I was given to try at Malvern Spring Show earlier this year. Most of you have probably heard of biochar already and the claim that this inert, carbon-rich material can help soil fertility and plant health. The RHS information in the above link says results can be mixed, with reduced effects found in alkaline soils. This may help to explain the lack of difference I found in my previous trial as VP Gardens is on a lime-rich soil. Plantsurge is a different beast altogether. It's a strong magnet which is attached to a hosepipe as shown in the photo above. It's claimed that it softens water, with the result more like watering with rainwater. The higher nitrogen found in rainwater is thought to be beneficial to plants. Gardener...
