Top tips?!

water well and fed them with a decent plant food.
Are you going to plant them straight out or grow them on?

If they are small and you are going to plant them cut some coke bottles in half to a make little Cloche to go over them and dont forget to slug pellet around them.

I find getting lots of containers/trays to sit the pots in a d watering from below helps.

Sprinkle a thin layer of vermiculite on top of the compost - it doesn't go rock-hard in the way compost sometimes does.

but if it does go rock hard soak the plant in a tub of water

sorry, repeating advice!
