Our sunflower experiment is coming along nicely. No clear relationship between soil amendment and growth yet. But I’m hypothesising we will see a difference in the actual flower and seeds. Time will tell…

Our grass experiment is coming along very nicely in Cumbria. Rain and warm weather has helped. Now we leave it for a month and see what impact the soil amendments have had.

It was great talking to the Sussex Kelp Restoration Project today. For someone who has not analysed any Sussex kelp they were so welcoming and inquisitive it was amazing.
