1869

Beet —seed from plant growing in group — & seed from solitary plant— no additional aid. —

(Jun 5 the row out of doors of self-plants has come up very badly & L. [Lettington] turned up earth & found that very many seed had germinated & then died.)

The seeds were sown on to 2 sides of 2 great Pots. Kept in Greenhouse & in the 2 rows in open ground: the latter were protected during winter by a little straw, but many leaves were killed by the frost.—

None of the plants in Pots or open ground showed any differences last year, or during the winter; but in early May 1870 some of the crossed, when they first began to throw up flowers look rather taller & finer. —
