Are they rootstock or edible varieties?
I planted 25 rootstock seeds last year in small pots. A third sprouted, of those about half promptly died, and I have five left that are barely 4 inches tall. I think I need to start earlier in the season next year, and with better seeds.
Normally if I have more seedlings than I need, and can't give them away, I just toss the weakest ones until I have a reasonable amount.
