long leaf speedwell

Water long leaf speedwells (Veronica longifolia 'Joseph's coat') regularly, but avoid overwatering. These plants prefer their soil to be kept lightly moist. Aim to water the plant when the top inch of soil has dried out. During periods of hot, dry weather they may need to be watered every 2-3 days. Overwatering may cause root rot, so it is important to only water when the soil has had time to dry out.

Long leaf speedwell (Veronica longifolia 'Joseph's Coat') needs full sun to partial shade for optimal growth. It will tolerate full sun in cool climates with well-draining soil, and will do best with a few hours of morning sun and afternoon shade in hot, sunny climates. During summer, the plants should be located in a spot where they will get plenty of direct sunlight for at least 5 to 6 hours a day. In spring, 6 to 7 hours of direct sunlight a day is ideal.

Long leaf speedwell (Veronica longifolia 'Joseph's Coat') should be pruned in early spring before new growth begins. The shape of the plant should be established by pruning annually to control size and improve flowering. Cut back any large, unruly shoots and thin out or remove any stems that are dead, damaged, or crossed. Remove any spent flowers from the previous season to promote continuous blooming. Prune to the desired shape to encourage increased flowering and vegetation growth. Try cutting back 1 third of the stems up to 10 cm from the base of the shrub to promote new healthy growth and flowering. Lightly shearing the tips of the remaining stems will also encourage healthy new growth and flowering.
