Hats off to Gardeners Worlds’ Alys Fowler and Garden Organic’s Bob Sherman for helping to plant an allotment at the proposed site of Heathrow’s new runway.

Check this out. Gardeners World presenter Alys Fowler and Garden Organic Bob Sherman have joined forces to plant an allotment at the site of the proposed 3rd runway at Heathrow Airport. I am so pleased we have a new garden presenter prepared to step out of the gardening arena to comment on wider environmental issues.

Babs2Hay and Cardiff

Barbara Haddrill is taking her talk about her book Babs2Brisbane to the Hay Festival and Cardiff Borders next week. Hay on Thursday and Cardiff on Saturday. Babs travelled overland to Australia to be a bridesmaid at her best friends wedding because she wanted to avoid flying for environmental reasons. Her talk is inspirational – suggesting how much we can all do to make a difference. For more details visit www.babs2brisbane.com.

Make your own wormery

The easiest recycled wormery I’ve come across is at the Yalding Organic Gardens in Kent. It’s made with three fairly large polystyrene boxes – the type used for packing vegetables or fish. Ask around your local market for spares. Quite often, they’re left at the end of each day for waste collection, so it shouldn’t be a problem finding some. Each box usually comes with a lid, but you only need one: discard the others or use them as seed trays.

Make a hole in the centre of the bottom box, 2.5cm (1 inch wide. Place the box on two small columns made of some scrap material like old wood, bricks or concrete blocks. The hole in the bottom box allows excess moisture to run out. Place a small container underneath and then dilute the liquid that collects and use as a plant food. It’s powerful stuff – use ten parts water to one part worm juice. Take the second box and make seven or eight holes in the bottom. These holes are for the worms to climb up and down between the boxes so they need to be at least worm-sized (remember that baby worms grow fatter every day!). Place this box on top of the first. Take the last box, make the same number of holes and place on top of the second. Put the lid on top.

To start, place kitchen scraps and small amounts of scrunched-up (not flat) cardboard in the bottom of the first (single holed) box (or some shredded bills mixed with a few leaves) for bedding, along with 100 tiger worms. Keep on filling with kitchen scraps and a little bit of cardboard and paper. When the box is full, place the next box on top of it (one with several holes) and start filling it. When that is full, do the same with the top box. The worms will move through the holes between layers in search of food. By the time the top box is full of food waste, the bottom box should be full of worm casts. Take it out and empty the contents (being careful to lift any worms you dislodge back into the wormery). You can put it straight onto the soil or use it as part of a mix for potting compost.
