watering
Longleaf speedwell requires frequent watering, with about once or twice a week being ideal. The soil should always be damp, not soggy. Be sure to check that the soil does not dry out, as it may be necessary to water more often during particularly hot or dry weather. During the winter, water should only be given when the soil begins to dry out.
sunlight
Long leaf speedwell (Veronica longifolia) is a cold-tolerant perennial plant and requires full sun exposure for optimal growth. It does best in direct sun for at least 6 hours each day, ideally, between late morning and early evening. This plant should be shielded from direct afternoon sunlight, as it may become too hot for it. It may be suitable to coexist with other plants near it that offer some shade, however, it needs adequate access to the sun. Water and supplemental fertilizer may be needed if the soil is poor and it may need some protection from strong winds.
pruning
Long leaf speedwell (Veronica longifolia) should be pruned in early spring, just as new growth appears. Pruning should be done lightly, removing only about a quarter of the total plant growth in order to maintain its full shape and size. Deadheading should also be done to remove any spent blooms in order to promote continued flowering. This species is best kept to the same size and shape every year, so it is important to prune the same amount each year.
