By March I will have thoroghly cleaned out my cold frame and painted the inside white.
March is the time I start to move my plants on from 3” pots into 5” pots and for this I use the same mixture as I did for the 3” except that I use John Innes number 3 instead of number 1, mixed with a multi-purpose compost.
Once I have potted them on I will leave them in the green house for a further few days prior to moving them into the cold frame.
When they are in the cold frame remember to watch out for severe frosts. If there is a frost forecast protect your plants by covering the cold frame with either an old carpet or some heavy duty poythene. You should also keep up with your spraying programme as a deterent for White Rust, Green Fly and Black Fly.
Again when they are in the cold frame I spot water, meaning only water those plants which are giving me signs that they need water. Those plants which turn a bluey green or wilt on a morning, these plants will get watered and by doing this you are encouraging a nice healthy root system.
The first week in March also sees me stopping my first plants, the plants which take more time to develop such as Joyce Frieda (7th March). Later on in the month I take varieties such as Billy Bell and other early intermediates.
Now is the time to have a soil test taken on your plot of land, ensuring that you use a reputable company who carry out soil analysis.
