- Plants can take up food through their green leaves and stems. Dilute liquid feed by twice the recommended volume of water to avoid burning the leaves. Spray a good quantity on to the leaves later in the afternoon is more effective. Bulbs like Crocus and Daffodills benefit as they are building up reserves for next year. Stressed and weak plants will probably pick up after a foliar feed but thick leaved plants are less receptive to feeding this way.
- Hardy shrubs that have had the leaves browned off by frost damage will recover all being well. My hydrangeas have been frosted despite leaving the old mopheads on for a bit of winter protection. I will trim the brown very lightly to avoid damage to the buds. Other shrubs can be trimmed back to the healthy shoots or leaves but if another heavy frost is likely I would leave the trimming job or protect with horticultural fleece. My Pieris japonica have been damaged but the new red leaves should still perform.
- It is still too early to sow half-hardy annuals as even cold weather will kill them off. Hardy annuals should be acclimatised to cold and wind gradually. This gardeners call ‘hardening off’ and is done by bringing plants into exposed areas during the day and moving them indoors or protecting them at night.
