Ladybirds

This is a ladybird larva. Not a bit like a ladybird, so don’t mistake it for a pest like an asparagus beetle (I’ve done that). Ladybirds, most people know, are excellent predators – eating aphids, mealybugs, scale insects, whiteflies, mites and other insects. Their larvae are even better. In the weeks it takes for them to develop, one larva can eat 500 aphids before pupating. The aphid (black and greenfly) are menaces – sucking the life out of beans and brassicas. A single cabbage aphid has the potential to produce 1,560,000,000,000,000,000,000,000,000 more aphids (I don’t know who counted them), though, for various reasons, this never happens. One of the reasons is, of course, the ladybird.

Even if your broad beans are sucked of life by aphids, don’t be tempted to use pesticides. They can make the problem worse. The pests will eventually adapt or become resistant to the chemicals and you might end up killing beneficial insects – such as ladybirds – as well. Chemicals also destroy the organisms in the soil that transform rotting material into food for your plants so that you need to rely increasingly on fertilisers and more pesticides. So, you need to encourage the good bugs by giving them the habitats and plants they like – basically plant a good variety of plants and leave wild patches. The plants will drop their leaves which provide places for ladybirds to overwinter. It’s essential to have nooks and crannies for ladybirds to lodge in so that they stay in the garden. If they find a good hibernation site their numbers will increase. Useful plants are ones that form basal rosettes, such as mulleins and evening primrose, umbellifers such as fennel, and plants with dense foliage such as brambles and ivy.

You can probably tell I have referred to A Book or two. One is called Pests by Charlie Ryrie and the other is Ladybirds, Natural Pest Control by Darren J Mann.

Clean up evening

We had a gathering of gardeners and volunteers last night. The Man from the RHS is coming to assess us tomorrow for the It’s Your Neighbourhood competition, which means we needed to clear up the confetti of beer cans and weird muscle tonic bottles (I’m talking proper boy muscle, from the Titan Gym next door) which are thrown over the wall from Mare St. We should make an inventory of the detritus that appears – lots of cans, crisp packets, fast food wrappers (thanks Col. S) of course, but also empty methadone bottles (thrown in joy or despair I wonder) and, one one occasion, a dead cat. A little archaeological survey of life in this corner of Hackney.

Another though, was our evening activity.  We mowed, weeded, organised, built, shovelled, painted, snipped and made tea.  This is what it looked like before we started.

This scene, understandably, was particularly upsetting to Jane who was responsible for the scaffolding shelves below.

We did a lot of mowing

 

Bee Seminar by Ian

Squeezed in a bit of bee school and had time for some snail racing.

For or five snails racing towards a lettuce leaf.

And this is what it looked like this morning.
