Thanks Clodagh & Dick for very useful suggestions. Will get that Terracotem and let everyone know how it goes! Yes.. we have found the lettuce (and other things) going to seed no sooner than they have started to poke their heads up!
We have found a shaded - and another - semi-shaded part of the plot and will try nuturing the lettuce there.
Will post again when we have moved onto the next stage/read the book!
C&D;- apart from the Terracotem - would you ever recommend a lining of say plastic/other non-permeable layer in the bottom of our seeding bed to keep the moisture in? We are aiming to translpant the seedlings once we feel they are established enough to cope with the regular plots/ground…
All the best,
Susan
