Garden Gladiolus 'Blue Isle'

Mulch to retain moisture. Fertilize lightly.

Plant in a location that enjoys full sun and remember to water moderately. Blue Isle is generally regarded as a half hardy plant, so remember to protect this plant from frosts and low temperatures. Blue Isle needs a soil ph of 6.7 to 7.0 (weakly acidic soil - neutral soil).

Try to aim for a seed spacing of at least 7.02 inches (18.0 cm) and sow at a depth of around 4.29 inches (11.0 cm).

Plant corms at two-week intervals starting in early spring and until the end of June.

Blue Isle is half hardy, so ensure you wait until all danger of frost has passed in your area before considering planting outside - as a guideline, the minimum temperature outside should be approximately 2°C / 36°F.

Gladiolus can be harvested three to four months after planting. Choose either early morning or night and harvest before the top blossoms opens. You can snip back the spent flowers.

This variety tends to mature and be ready for harvest in mid summer.
