Deadhead to tidy for winter

Tidy the plant to make the garden ready for winter. When the flowering season concludes around mid-autumn, cut off the flowered stems to their base.

Spring-Autumn · Outdoors

Water to keep the soil moist

For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.

Without regular watering some plants never fully regain their beauty.

Summer - early · Outdoors

Feed a general fertiliser

Where plants have moderate needs for nutrients, they can simply be given a general feed, fairly early in the growth season so that the growth has plenty of time to harden off before the cold weather.

Give plants a general boost with the application of a general purpose fertiliser which is spread around the root area of the plant, with amounts as directed on the feed label.

Summer · Planting

Trim dead flowers to develop buds

Take off the flower as it fades. Cut the stalk back to the point where there is a side shoot, preferably facing outwards, near the base of the stalk. If the spent flower is removed this bud will then develop.
