The alkanet began to take over, and while it looks really pretty in early spring, with its fresh green leaves and brilliant blue flowers, it’s one of the favourite foods of the scarlet tiger moth, which shreds its leaves – very good from an environmental point of view, less so in terms of how it looks. The plant also suppresses many other plants, so we’ve gradually removed it to take somewhere more appropriate, to replace it with other wild flowers to keep the site looking good all year.
This spring we’ve also added more of these wild flowers, as well as a few non-native plants that work well in an area of naturalistic planting like this one, such as raspberries, to give some height and structure (and bees just love them!), purple toadflax, geranium macrorrhizum, Michaelmas daisies and bugle. All of these were propagated from plants that had become congested at the Memorial Gardens. We also donated some seedlings of Bowles’ Golden Grass from one of our gardens, via the Pocket Park by the station, another of our sister sites. In this case, it’s not so much a source of nectar and pollen for bees, as the kind of habitat some of them need for nesting, as several species nest in clumps of long grass, including that one.
And so it continues – we’re now potting up some rudbeckia for a couple of months for autumn colour; we’ll plant it out in a couple of months when it’s developed a good root system, as that means we won’t have to spend so much volunteer time watering new plants to get them established.
And the last thing we’ve been able to share is some of our leaf mould, thanks to hours of work by the Memorial Gardens team and much-appreciated contributions of sacks of leaves from Leighton Buzzard Narrow Gauge Railway and many other residents and gardeners. We now have enough for any of our bee-friendly sites around Leighton Buzzard that need it – generally, we don’t improve the soil at all in wild flower areas, but at sites like this one, we need to add organic matter without adding the fertility that comes with compost or manure. We make sure the ground’s wet, then just put the leaf mould on top (not digging it in even with a trowel, as that disrupts the soil structure), and it starts holding in moisture at once and keeping weeds down by shutting out the light they need to germinate. Then worms start pulling it into the ground, and doing the hard work for us!
What has been really nice for us has been the appreciation of members of staff, who said they’d enjoyed watching what we’ve been doing, and they really like it!
