My Blue Blue Blueberries. – Blueberry & Lavender Jam

“It’s sad and it’s cold at the bottom of the sea but at least I’ve got my blueberries with me.” – Blueberry Boat by The Fiery Furnaces.

Well it finally happened. The inventible blight has struck at the plot. With weeks of wet and warm weather the tomatoes have finally succumbed to the dreaded blight. As we do not spray, trying to be as organic as possible, blight unfortunately is an inevitable fate for our doomed outdoor tomatoes.The 2012 growing season so far certainly hasn’t been a contender for the best season ever, however not everything has been moping down at 18a. Non non, the blueberries and black currants in particular have been quietly fruiting modestly in the soft fruit bed. I might even go as far to say their the best blueberries we’ve ever grown.

It’s their third season growing at the plot and like many things it’s often not til their third season that they really start to hit their fruiting stride. We have three bushes of different varieties , an early (Duke), mid (Bluecrop) and late season (Brigitta) so we’ve been enjoying handfuls of sweet homegrown blueberries on our breakfast muesli and hopefully will continue well into August.

The season started a little tricky for the blueberries during the early drought and heat but once the deluge of rain we’ve been having here in the UK began (and never seemed to stop) the blueberries seem to have been loving it! After an iffy spell during flowering where the leaves began to redden prematurely feared I may loose any berries for this season. But they soon responded to a regular feed with an ericaceous seaweed based feed with added iron (Thank you @Saralimback for your wonderful Horticultural knowledge). The problem was despite planting my bushes direct into the ground in root control bags, I still needed to maintain the right acidic Ph. A mulch with ericaceous Compost at the start of the season just wasn’t enough. With roots close to the surface they have creeped over the top of the bags and into the native soil. Our plot may naturally err on the side of the acidic but not enough for the blueberries. So regular feeds and the odd mulch with spent coffee grounds ( not too much as these tend to have a neutral Ph.) seem to have done the job.

So for next season it will all be about maintaining that low Ph. There are many old wife’s tales about adding old rusty iron nails and horseshoes (It was common practice for Victorian gardeners to plant their hydrangeas with a mix of rusty nails or old horse shoes) to the soil but in reality this does very little to raise the acid levels. What I really need to find is some composted pin needles. So a trip to woods is on the cards! A good mulch and feed feed feed is the blueberry mantra!

To celebrate the beauty of the blueberry why not try this Blueberry & Lavender Jam. Now I cheated a little here, my allotment blueberries aren’t quite all ripe at the same time to make up the quantity needed to make a jam. So I bulked it out with some British grown blueberries from the shops to make up the numbers. Blueberries and Lavender make gorgeous dark and silky floral almost savoury jam. Lovely on a buttermilk crumpets, phwoar-yeah!

For me itโ€™s all about the simple things in life. Pottering around my allotment, growing things indoors and out, baking a good cake, being outside, pretty things, vintage finds and a good pot of tea. Itโ€™s all the small things that make me tick, noticing the beauty in everyday things. Although this blog initially was intended to be a blog about all these things its evolved into being basically a blog about our allotment. Our adventures, highs and lows, wins and loses. So join me & Mr Wilson as we learn from our mistakes and successes down plot 18a.

  1. Hmmm I love blueberries, unfortunately I planted out mine a bit to soon and a sudden harsh frost killed it. I am planning on buying a few more next year. Good tips on how to maintain the acidity of the soil, thanks for that!

  2. Definitely going to up the number of blueberry bushes at my allotment, they tasted amazing this year and I’d love to try this recipe.

  3. Interesting recipe idea. One of the community gardens I work with grows blueberries, I’ll pass it on. Had never heard about the iron ‘old wives tale’, will be looking it up ๐Ÿ™‚

    1. Thank you. The recipes a little different to the usual jam recipes. The lavender gives an interesting savoury edge. The old wife’s tales about raising the Ph are interesting. I guess it must have made sense at the time, need iron in the soil? Why not add some rusty iron nails!
