Since last summer I have been saving up toilet rolls (and kitchen roll tubes cut in two).
These are my "root trainers" for this year. There are quite a few.
I stand them in cell dividers in seed trays fill with compost, sow and cover with vermiculite. This arrangement ensures enough air circulation between the tubes to stop mould becoming a problem. Here's my first batch of the year in the propagator. Tomatoes, Chili, Cucumber, Celeriac. From here on it's a rolling production line until the end of May
For the record I sowed my first early potatoes (Sharpes Express) at the plot today. The broad beans have emerged and the garlic is looking all the better for a weed and feed.
