Q.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.

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.
