These corms are ready for planting any time from March/April with flowering mid July/August onwards.
Gladioli like to be planted in a sandy soil, place about 1/2” sand in the bottom of the hole and a light covering over the corm. Corms should be planted 4-5” deep and 6” apart. Grow in a sunny position, papilio can also be planted in mixed herbaceous borders and left to multiply over the following years.
If planting in a heavy clay baset soil: dig a hole twice as big as the planting area and 6” deeper. Mix soil with a coarse sand before planting corms. Place some mixed soil and sand in the hole and plant your corms on this, then cover your corms with the remaining soil mix.
During growing season feed the gladioli with a top dressing of Vitax Q4 monthly. During prolonged periods of warm/very dry weather gladioli may require additional watering. This should be repeated each year.
