May is a buzz of activity in our organic demonstration garden. We'll be sowing the first peas, beans and carrots in our vegetable garden - and they'll be delicious rows of heritage lettuces and radish to admire. Our two ponds will also be coming to life: look out for newts, which will be making an appearance in the pond to mate and lay eggs, and frog and toad spawn. Bright sparks among the flower and shrub border will be our alliums and beautifully scented auriculas and ceanothus. Our 30-strong National Collection of comfrey will be in flower at this time.
