watering

Hybrid ornamental onion (Allium) plants require regular watering for optimal growth. Water your plant every 5 to 7 days to keep soil consistently moist, not soggy or dry. During the summer, water more frequently if the soil dries out faster due to warm temperatures. During the winter, water less frequently if the air temperature is cold. Whenever you water, apply enough so that the water begins to drain through the bottom of the pot. Make sure your plant's drainage holes aren't blocked, as that can cause overwatering. Always check the soil before watering to make sure the top of the soil is dry.

sunlight

The hybrid ornamental onion species (Allium (incl. hybrids)) is an ornamental bulbous perennial that prefers well-draining soil and full sun. In general, the plant should receive 6 to 8 hours of sunlight each day, with a minimum of 4 hours for the best flowering performance. If grown indoors, hybrid ornamental onion should be placed in a south or east-facing window for the most light, ensuring that it gets at least 4 hours of direct sunlight each day. Hybrid ornamental onions can withstand more hours of full sun per day during the cool months to make up for the hours it misses in the summer.

pruning

Hybrid ornamental onions should be pruned once a year in late summer or early fall. Pruning should aim to remove any dead or damaged stems and foliage, as well as any overcrowding. Generally, prune no more than 1-third of the overall plant material to ensure your ornamental onion stays healthy.
