Here's something you might want to try.

 The accumulator.
In the latest edition of 'Organic Gardener' (OG) there is an excellent article espousing the virtues of comfrey. One of those virtues is the high level of potash and good levels of nitrogen and phosphate contained within their leaves.


They, OG,  also suggested to use the leaves in layers about 5 cm thick as a mulch so that while the leaves are wilting and breaking down, which happens quickly, the nutrients are leached into the soil and become available to the plant you have mulched.

Here is my tomato with the comfrey stuffed around it. I'm using it on my tomato because it needs a good regular supply of potash for fruit setting and with all our rain lately they have become a bit etiolated.




I went one step further than OG suggested and covered my comfrey with compost and then mulched with some aging straw.


I also mulched and composted right up to the stem of my tomato. I did this because tomatoes don't get collar rot because they have a very active advantageous root system which allows them to produce new roots from their stems and thereby increasing their ability to access available nutrients from the soil

Cheers and happy tomato cropping
