Description: Tree onions are clump forming onions and can be grown by planting single onion bulbs which clump over the season. Another way to grow them is to plant the bulbils which are produced at the end of the flower stalks. Each bulbil will form either a single bulb or a small clump of bulbs.
Planting Instructions: Do best in light soils with good drainage and need a sunny position. Enrich soil with well rotted manure, compost, lime and Nature’s Garden prior to planting. Plant each bulbil just below the soil from May to July at 14 cm diagonal spacings. They benefit from a weed suppressant but light mulch.
