Earlier in the year I made my first batch of comfrey ‘tea’ and trialled it on courgettes, tomatoes and squash. Here’s the outcome:
The picture indicates what I observed: that the courgette plant on the right has more growth and indeed gave more fruits. Unfortunately, all my outdoor tomato plants suffered blight, so I had to remove them from the trial. I was similarly unlucky with the winter squash on the test bed; a cold spell at the vital time meant a lack of pollinators and therefore poor pollination. I only had 2 fruit set, and these were tiny, although they were on the plant that benefited from the tea.
The bed is now cleared and under cover for a well-earned rest overwinter, ready to have compost added in early spring. In conclusion, I think the stinky mixture is well worth brewing if you have the space (and the nose) for it! Read on here for the previous posts.
