Ponds You could take the opportunity to dig a new pond - the spring rains may help to fill it. We recommend a minimum depth of 60cm (2ft) at the deepest point, to reduce the risk of the pond freezing to its full depth. Gently sloping contours between the shallow and deep areas, and between the bank and the water, are more wildlife-friendly, and help to make marginal plantings appear natural. In the Greenhouse Greenhouse bulbs that have finished flowering (e.g. freesias and Lachenalia) can now be fed weekly with high potassium feed (such as tomato fertiliser), to build up the bulbs before resting them over the summer. Reduce feeding and watering as the foliage starts to die back, and then lay the pots on their sides under the greenhouse bench until next autumn. Begonia, Gloxinia and Achimenes tubers can all be planted this month. Begonias and Gloxinias need to be planted hollow side upwards; Achimenes can be planted on their sides, in trays if necessary, before potting them on as necessary once growth appears. Lily-of-the-valley (Convallaria) that was lifted from the garden to use as winter-flowering pot plants in the greenhouse, should now be planted back outside. 115 Maintain a minimum of 5°C (42°F) to prevent Fuchsia, Pelargonium and other tender plants being killed by the cold. Higher temperatures (at least 12°C/54°F) will be needed for tropical plants. Fuchsias can be started into active growth (if not done last month) by repotting, increasing watering, feeding (with a slow-release fertiliser such as blood, fish and bone), and putting them in a sunny place. Those that were started up in January can now be sprayed with water occasionally to raise humidity, encourage growth, and help bud break. The RHS is a UK charity established to share the best in gardening. Their work is driven by a simple love of plants and the belief that gardeners make the world a better place.
