Spring Tasks in the Garden
At last it is time to begin. After the long winter period with nothing to do, work begins in March and increases rapidly:
• Sow seed of summer annuals,and vegetables, either in the house or directly in seed trays the on balcony or terrace, depending on temperature.
• Cut back plants in containers and at the same time take cuttings to root and make new ones.
• Divide plants such as periwinkles, echinaceas, astilbes, clay, bergenias and thyme.
• Your “green room” can already be beautiful with colourful spring-and tuberous plants, herbaceous perennials and early-flowering biennials.
• Cut back perennials and other woody plants.
• Cut back bedding.
• Repot container plants. As a rule of thumb: younger plants should be repotted after 2 to 3 years and older ones after 5 to 6 years.
• Do not forget to air the greenhouse well in warm sunny weather, so that the temperature does not get too high. Vegetable seedlings in particular resent this. Smallfor use on a balcony and terrace to provide some protection in the winter are available from garden centres and garden mail order firms.
• From April give container plants that have not been repotted a light feed for example with organic liquid fertilizer.
Alternatively, remove the upper layer ofand these with a mixture of compost and fresh soil. This method is particularly good for bay trees.
• Hardy container plants should be slowly accustomed to warmer conditions in the open air, but they must still be protected from excessive sun and late frosts.
• Now it the time to prepare fruits such as blueberries and raspberries, so that the fruits will be ripe in midsummer. With raspberries, all shoots should be cut back in December to soil level, because fruits only develop on new shoots.
• Formal bushes and hedges such as box, privet orshould be clipped to shape and fertilized as required, ideally with long working garden fertilizers. The clippings of box can be planted as cuttings to increase your stock of plants further.
• Summer-flowering bulbs can be brought out of storage and planted out.
• From mid-May, or depending on your local conditions, all frost-sensitive plants can be put outside. The summer flowering season begins.
• With warmer weather the time ofbegins: aphids, spicier mites and snails may become troublesome from May onwards. Check your plants regularly. Roses may suffer from , or .
• Cut off suckers from rose rootstocks.
