How to Grow Convolvulus Minor

Select a spot in full sun. Convolvulus minor grows best in soil that is not overly fertile, as long as it has good drainage. Because are low-growing and do not form vines, Convolvulus minor is suitable for the front of the flower border.

Soak the seeds overnight or nick their hard outer coat with a nail file. This hastens germination.

Plant seeds about 4 inches apart in rows 8 to 12 inches apart. Thin the seedlings so the remaining plants stand about 6 to 8 inches apart when the seedlings have two sets of true leaves.

Water the seedbed after planting the seeds. Spray the surface of the bed with a hose end sprayer to keep the soil moist until germination. Thereafter, water only when the surface of the soil is dry. Overwatering will cause them to produce fewer flowers.

Fertilize Convolvulus minor with water-soluble fertilizer every 10 to 14 days until mid- to late August. Spray the mixture on the foliage, following label directions, or put the fertilizer solution in a watering can and hand-water the flowers.
