Babiana Stricta is an early-summer-blooming bulb that produces as many as 20 sweetly scented, 1 1/2" flowers in combinations of blue, rose or pink. The blooms last for 3-5 weeks.
Plant: 3 Bulbs Per Sq Ft
Bloom Time: Late Spring
Planting Depth: 2"
Zone: 6-10. In northern climates lift in the fall.
Spade or till the soil to a depth of 8 to 10 inches. Dig in 2 to 3 inches of compost or manure, as crocosmia prefers rich, well-drained soil.
Plant crocosmia when the soil is at least 55 degrees Fahrenheit and all danger of frost has passed. In cooler soil, the corms are susceptible to rot.
Dig a hole for each corm, making them deep enough that the corm will be at a depth of 3 to 5 inches. Allow 6 to 8 inches between each corm.
Water crocosmia deeply after planting. Thereafter, water regularly throughout the growing season. Provide enough moisture to saturate the roots, and then withhold water until the top of the soil feels dry. Never over-water, as crocosmia is relatively drought-tolerant and the corms may rot in soggy soil.
Watch for spider mites, which often feast on the foliage of ornamental plants. Spider mites look like tiny specks that gather en masse on the underside of leaves. Insecticidal soap spray is often an effective method of control. Healthy plants are less susceptible to damage.
Protect crocosmia from slugs, which often chew holes in the leaves. Prevent the pests by removing leaves, grass clippings and other plant debris from the soil around the plants. Control infestations with slug bait. Apply the bait strictly according to label guidelines.
I won't know whether the bulbs grow well until next spring, but they arrived promptly with no obviously damaged or moldy ones. They also come with basic plant information and planting instructions. It was difficult to find any Babiana bulbs for sale, so I am happy I ordered these.
