Veronica incana

Spiked speedwell does best when it gets plenty of sunlight throughout the day. This light is essential for its healthy growth and development. In the wild it is usually found in open areas with abundant sun. Both too much and too little sun can cause impaired growth or faded leaf color.

Spiked speedwell possesses the capability to adjust to diverse temperature conditions, though its spread can still be constrained by varying combinations of moisture and heat conditions. It flourishes optimally in hot weather during summer with sufficient rain or hydration. Extended stretches of overcast and wet conditions, in addition to sustained high temperatures, can augment the chances of Spiked speedwell perishing. During winter, appropriate safeguards against chilling cold can enhance the survival probability of the plant.

Early spring, when the Spiked speedwell is coming out of dormancy and beginning active growth, is the best time to fertilize. Fertilization supplies essential nutrients for healthy development. Although Spiked speedwell has relatively modest fertilizer needs, applying fertilizer once a year can improve its survival and encourage better, longer-lasting flowers.
