Doing seeds is kind of scary. I wait until they have two seed leaves and then gently lift them and put them into pots of soil. 4 rows of three in a four inch pot. I did 24 seedlings this afternoon and can hardly see the difference in the number of seedlings. Of course some seeds will not thrive and I only select the strongest. I'm thinking about 50 seedling with a 50% survival rate for those so that's still 25 more pots of plants. It can get out of control! Of course if they all survive ... say no more.
(I noticed some buds on your Strictum this afternoon)
