nutcutlet. I face a similar problem with watering over winter, not knowing when or how much water to give plants.
Last year the plants were given a good bottom watering in October and it wasn't until about February/March time when they needed water. They were bottom watered again but as there's still chance of a frost I put less water in the trays and waited for it to be absorbed before taking a few plants out of their pots to see how far up the pot water had been absorbed, if it half covered the roots, I judged that to be enough, if not more water was added to the tray.
Sounds a bit pain staking but after nurturing plant through a cold winter didn't want them to die from over watering a few weeks before planting out, worked for me
