There is little difference in the yields of the first three plantings, 
no doubt because the weather up to the middle of April did not 
encourage growth, while after that the plants made steady progress 
without the usual set-backs due to late frosts and the like ; but the late 
plantings, especially the June one, led to serious reductions in the crop, 
moreover the proportion of chats was markedly greater in both late 
plantings, but especially in the June-planted set. April seems the best 
month to plant at Wisley, and though seasons may make some 
difference, for all but quite early varieties planted in the most 
favourable positions probably from the middle to the end of the 
month is best if the seed is previously sprouted.
