watering
Large speedwell (Veronica austriaca subsp. teucrium 'Crater Lake Blue') should be watered thoroughly once a week. The best time to water this species is in the morning just after the sun rises. During the warmer months, it may be beneficial to water this plant twice a week. Be sure to check the soil prior to watering to ensure it is not overly wet or dry. Avoid overwatering as this can cause root rot.
sunlight
Large speedwell (Veronica austriaca subsp. teucrium 'Crater Lake Blue') is a midsize perennial flower that prefers direct sunlight. The plant should get a minimum of 6 hours of sunlight each day in order to promote blooming and overall health. If grown in a shaded area, the plant might not bloom as expected. Full sun exposure is ideal for large speedwells, and they should be grown in well-draining soils. High temperatures and humidity are ideal for this plant species. If grown outdoors, morning sun with some protection from the harsh afternoon sun is ideal. If grown indoors, an east-facing window will provide ample sunlight.
pruning
Pruning should be done twice a year to help Large Speedwell (Veronica austriaca subsp. teucrium 'Crater Lake Blue') reach its full potential. In late spring, about 1 month after blooming, trim back any dead flower stems and tangles of sterile shoots. This will help to encourage new growth and better shape. In late summer, around August, prune back the outer stems by up to 1 third of their length. This will help the plant keep its dense, mounded shape and will also ensure plenty of stems for the next season.
