Look after your tender treasures
By November we can no longer risk leaving any tender plants outside. If we have not already had our first sharp frost, it is just around the corner, and at Longmeadow that can easily mean temperatures of -10°C or below. So both the greenhouses are now full of plants, some of which, like Salvia elegans, are just hitting their flowering stride. I water them to keep them going, but start to radically reduce the watering of other potted plants like citrus, pelargoniums and fuchsias, and I do not feed them at all. The greenhouses are heated, but only to keep them frost-free, with the thermostat set at 7°C. This reduction in water, feed and heat means that, although the plants are protected from the worst of the weather, they can slow down and rest over winter.
Keep salvia blooms coming with occasional watering
Bring tender plants, such as standard fuchsias, indoors before frosts
