Speaking of lettuce. That reminds me. My lettuce and spinach experiment. Little Gem lettuce is growing very well in all three of the soils, maybe a slight edge in the Mushroom Compost.
There is a BIG difference between the Compost and the other beds for Spinach. We’ll see how it goes from here, but it is looking like Spinach of the future will be planted in Mushroom compost.
The black seeded Simpson is slightly better in the Compost, and secondary in the Mel’s Mix plus top soil plus Mushroom compost. Dead last is the top soil.
Conclusion: So far the Little Gem seems to do well in a variety of soils, but Spinach definitely prefers the Mushroom Compost, and the leaf lettuce is inferior to Little Gem at this time of the year, or maybe the seed is just not a good batch?
I have been planting Simpson Blackseed lettuce for several years. It grows fast and can be planted several times each year.
