Gardening Questions And Answers
Delphiniums are hungry plants, which means that they need feeding regularly. Apply a liquid fertiliser every couple of weeks once the first shoots appear to encourage strong growth. Spring is also the best time to stake taller varieties, either with canes or using a frame that plants can grow up through.

Nothing quite beats the drama of delphiniums. In June and July, they produce towering flower spikes that can reach over 2m tall.

They are especially active in periods of cool wet nights and warm humid days, causing leaves to wilt and die. Plant delphiniums on well-drained, fertile soil with enough space between them to encourage good air circulation. Water them early on sunny days. Try to keep their foliage dry by watering just the soil.
The plants must be watered well before application. Another option to reduce the soil’s PH is to add organic matter such as coffee grounds, fruit and vegetable peels, etc. Adding fertilizer that is low in phosphorus and high in potassium content will also help preserve the color of delphinium blooms.

Delphiniums fare best in summers which are cooler, hot dry summers are not ideal, which can exacerbate their tendency towards powdery mildew.
Delphiniums thrive in cold and moist climates and are native to the Northern hemisphere, most notably in the mountainous African tropics. The delphinium flower gets its name from the Greek origin Delphin, which means dolphin. If you look closely, the plant is thought to have unique, dolphin-shaped flowers.
