A long hot summer

02 October 2018

It’s nearly three months since we managed to post on this blog; I’m sorry for the long silence. This summer has really taxed us, with much more watering than usual both at the gardens and on our own allotments and the other gardens we look after. There’s been a knock-on effect too, as we couldn’t move any plants or try and establish new ones during the drought and unusual heat, so there’s been a backlog of work which we’re only just getting done. And now we’re running straight into the leaf-collecting season – though for the first batch we had help from the local preschool, who had a great time on Monday helping load leaves into bags (and run through them, and run around with those big-hand leaf collectors which a couple of the boys felt made them into mini Incredible Hulks).

Our original plan for this year was to consolidate the planting, and to try and reduce volunteer hours as we’d just be maintaining the gardens, rather than rescuing them from the invasive plants like white clover and self-heal which were choking the beds when we took over. This year, we said, we’ll just be able to do a bit of deadheading and move a couple of plants that would be happier in other places, and perhaps add a few more plants that we’ll have grown ourselves.

Well, along with the bit of deadheading we’ve had to do much more watering – we usually try to water as little as possible, partly so as not to waste a valuable resource, and partly because plants grown ‘hard’ (with all they need, but not overfed or overwatered) seem to thrive better. But we did end up watering many parts of the beds with a hose five times in the last five months, and using watering cans for specific plants that weren’t sufficiently established before the heatwave started. These include the five new roses, which need a proper soaking every week for the first year or so even in normal weather, to encourage their roots to get down into the soil; so we’ve given each of them a couple of cans of water every week. At least the thick mulch of leaf mould we put on in May has helped keep what moisture there is deep in the soil, and watering most of the gardens once a month is probably not too bad for this year.

We didn’t manage to sow many hardy annuals as the ground was just too dry and we’d have been watering them every couple of days, though we did raise a few tomato plants with the preschool (and the fruits are just beginning to ripen now). Their peas and carrots didn’t survive the heat, though, and we’re rethinking what we do in their bit of the garden – for a start, we’re adding more herbs and some lamb’s ears (Stachys byzantina) as they love the smells of rosemary, mint and fennel, and the softness of the lamb’s ears leaves.

At least with the combination of heat that stopped many weeds from germinating, and mulch that kept light away from those that were there, we haven’t needed to weed the beds since July, just before the In Bloom competition this year. We had a lovely sunny day for the judges’ visit, with the preschool children out in force demonstrating just how much they love watering anything and everything. The whole team came along, too, including our invaluable Duke of Edinburgh’s award student Miles, who’s helped us so much this year.

And in September we heard that Leighton Buzzard had been awarded 12 Golds, 2 Silver Gilts, and two ‘Best in the region’ awards (for Linslade Wood and for the Tactic youth project). The gardens are part of Mentmore Road park, which was one of the sites awarded a Gold – it’s good to know we’re all on the right track!

Looking back over the last few months

10 July 2017

As the summer flowers give way to the ones that’ll take us through autumn, it’s a good time to look back at how the gardens have been doing so far this year. It’s been quite tough keeping everything going, as we’ve only had two periods of rain several hours long since March, and that’s been it; so we’re having to water a lot more than we usually would to make sure there are always a couple of the bees’ favourite plants in flower right through the year. We should be looking forward to new plants coming into flower in a few weeks, but many of them are two to four weeks early – the Michaelmas daisies started flowering last week, in the first week of July!

Most of the plants established last year are doing OK despite the drought, but this has been the year we trialled bedding plants for their usefulness to bees, and bedding plants seem to be the divas of the plant world – they need constant watering, dead-heading, feeding, and weeding around. With hindsight, they weren’t the best choice. Still, the echiums are settling in and providing bright blue colour in the beds, and welcome nectar for the bees – though nothing like as much as their wild equivalent in the second bed down from the car park, where we have two Viper’s Bugloss (Echium vulgare) plants, tall spikes of smallish blue flowers, covered in bees most of the time. The ‘Disco’ French marigolds provide great bursts of bright orange – but then, so do the California poppies they’ve largely displaced, and while there have been a lot of bees on the California poppies, there haven’t been many bees on the marigolds. The mignonettes are finally growing well and flowering, and they do smell sweet, but it’s taken a lot of watering and TLC to get them established, and we have limited resources. So while they’ve provided a nice change this year, I don’t think we’ll be repeating the experiment. We’ll need to find something else for the children from Mentmore Road Under 5’s to plant next year – they thoroughly enjoy planting things out, and watching them grow and flower!

Last week some of the children had fun picking the peas they’d planted a couple of months ago, and eating them straight from the pod, and they also lifted some of their carrots to see how they were doing (fine, but nowhere near ready). That didn’t seem to bother them at all – they still found it magical that they could dig out little green feathery plants and find a real carrot underneath, even if it was only 10cm long! Next year we’re thinking of getting them to plant early potatoes so they can dig up some buried treasure well before the end of term; we always have to race a bit to get them something to harvest before they break up for the summer. A couple of weeks ago they planted some annuals for the autumn (sunflowers and Cosmos) and a few foxglove and hollyhock seedlings, so that should give them something to watch grow next term. I’m not sure they believed me when I told them the tiny hollyhock seedlings would grow into plants like the ones twice their height in the next bed.

The Leighton Buzzard Observer carried a nice article on June 20th about the cooperation between the preschool and the regular team.

The regular team have been doing more dead-heading and less weeding as our earlier work has begun to pay off, especially as we were able to mulch the ground with almost-ready leaf mould after we’d weeded it. The local blackbirds throw the leaf mould around too much – often, our first task of the day is to brush the leaf mould off the paths and back into the beds. Leaf mould usually takes a couple of years to rot down completely, and what we’re using isn’t quite a year old, so we should have less mobile mulch in future. We’re also thinking ahead to autumn, when we’ll be able to sort out some compost from the bins round the back, and top it with leaf mould to keep weed seeds from germinating.

We’ll also be lifting all the dead plants in the wild flower bed – they’ve gone over much faster than usual, and have grown much less than usual too. This is almost certainly due to the drought – we watered copiously until a couple of weeks ago, when we decided we were just wasting water by pouring it onto the ground to no real effect, as wild flowers don’t seem to respond as well as garden plants and all the annuals were clearly dying back much earlier than usual. So as usual we’ll start the gardening year in September by collecting seed from the poppies to sow once we’ve turned the soil and added compost.

Watering and mulching

13 September 2016

There are still a lot of bees in the garden – here’s one enjoying the coreopsis:

We’ve had very little rain for the last couple of months, and the ground’s dried out again very quickly even after a whole day of it.  We’d never claim to be a ‘drought garden’, but we do try not to use more water than we really need to. Even in this very dry summer we haven’t (yet!) had to use the hose this year, but the gardens don’t look particularly dry. This is thanks partly to the amount of mulching we did last year (putting leaf mould or compost on top of wet ground to hold the moisture in), and partly due to our choice of plants – garden perennials and many wild flowers need much less watering than annual bedding plants, for example. We use watering cans for a couple of weeks when we move plants or put new ones in, to get them established, then mulch them well and leave them to get on with it.

The exception is the vegetable bed where the children from the local preschool are growing peas, beans and carrots this year, where we’ve been using the watering cans a lot, particularly before the children broke up for the summer – they love watering things, and the runner beans probably had such a good start that they’ll survive any number of dry weeks now!

The mulch used for the bottom two beds (nearest the war memorial) last year was a proprietary compost made from wool and bracken, which has also kept weeds down for over a year and is still making a difference. We’re just beginning to notice a few weeds creeping back now, but it’s saved us a lot of time. It forms a bit of a crust, which does make the soil quite hard to work in the second year, so we haven’t used it this year in the other beds where we’re still moving a lot of plants round; there, we’re using garden compost round individual plants that need more feeding, or leaf mould where we just want to cover the ground over the winter, which is better for the soil. We’ve noticed a lot of ladybirds and other predators rooting around in it, which is good as we want to encourage them as much as possible around the gardens – this year they did a great job of seeing off any aphids that did try to colonise the plants!.

It’s a difficult balance at the moment – if we cover too much of the ground too early on, we’ll stifle all the self-sown Californian poppies, cornflowers and others that we’d welcome, but this is exactly the time when a lot of weeds start germinating, and we don’t want our volunteers to have to keep weeding the same patch again and again.
