Through out the trials this year at Wisley we are reviewing the chemicals which we use to grow our plants to a high standard. We feel that the general public do not like to or wish to use too many chemicals when growing plants, so we are trying to reflect that in our work. This year we have started a programme of spraying our Delphiniums (including the Delphinium, perennial, from seed trial pictured above) with a product called compost tea which is a mixture of enzymes and natural humic acids which supposedly reduces powdery mildew. The tea also improves soil bacteria and generally feeds the plant without the use of chemicals. We are applying this every two weeks and are excited about the potential outcomes, although not widely available at the moment we think this product has great potential, time will tell.
May is a very busy period for the trials teams and over the next few weeks we will be filling our beds with interesting trials which should be great to look at, we would love to see you in our corner of Wisley so feel free to come and have a chat.
