I have had the heater on during the night in my greenhouse for the past week as I have many small seedlings ( 80 tomatos to name a few!). I can’t remember needing it on as late in the year as this before. Normally I would have taken lots of chrysanthemum cuttings by now but some are only just beginning to shoot. Outside gardening has been impossible up to now as even before this last lot of snow the ground was still far too wet to work. My husband is getting uincreasingly frustrated! You can’t intervere with Mother Nature so we’ll all just have to be patient.
