I have planted my Delphinium seeds (in pots) too late (June).
The plants are now about 4 inches high with plenty of leaf. What should I do to keep them for next year - greenhouse, plant outside but will they survive the Winter? Keep them in the greenhouse or keep them on a sheltered balcony after re-potting in larger pots, as they are in the very small ones at the moment. Katherine

If you are located in England where winter temps hover between 30 and 40 degrees F ( -2 and 8 C) then you should be able to plant them in the ground and they will survive winter. I would mulch well, though. Choose a planting site that is moist and well drained and is protected from hot afternoon sun and winds.
