Delphinium 'Pixie Rocket® Neptune Rocket'

Spring - late · Outdoors

Feed with slow release fertiliser

Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)

This is a simple way to provide a nutrient boost as a single annual procedure.

Spring-Autumn · Outdoors

Water during dry periods

For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.

Spring, Summer, Autumn · Planting

Cut faded flower stems

Once all the blooms on the stem have opened and faded, cut the entire stem off.

Spring-Autumn · Planting

Protect from slugs & snails

Protect young plants and new growth from slugs; mature plants can withstand slugs though damage affects their appearance. Apply nematodes in Spring. Or sprinkle organic slug pellets thinly around plants. Barrier methods, eg copper tape, may help.

Summer-Autumn · Planting

Support tall stems

The plant may require support for long stems. Provide an artificial frame which it can grow through, or loosely tie the whole plant. A network of twigs can be woven together to provide a framework through which the plant can grow.

Tall stems can lean or be battered by weather. Support the plant to keep its vertical lines, aiming for a natural appearance which is easy on the eye.
