I was reading in you mid-May notes that you have found certain composts to be poor this year. I’ve been using Levington’s Seed and Cutting compost this spring and found it very variable. In particular, the first bag was used to sow Cauliflower and Cabbage seedlings which grew away fast and were transplanted with large healthy leaves near the end of April. I used the second bag to sow Landini cabbage and Brussels Sprouts, but have planted both sets out as rather small plants today with many leaves becoming pale and off colour. When I transplanted out, there was a healthy root ball, so it does suggest that some nutrient deficiency was present in the seed compost of the second bag.
The kale and chard were similar, but since planting them out into newly prepared beds with 6 inches of compost, they have taken off well and will clearly do fine.
I’ve never had any problems with John Innes, so perhaps I will stick with that in future.
