Stock flowers grow in thick clusters on the spike-like stems. Stock will tolerate light frost and is useful for winter bloom in mild climates. Elsewhere, plant as early in the spring as ground can be worked.
Sunlight - Despite their love of full sunlight, stock flowers will thrive in partially shaded conditions as long as they get at least 2-3 hours of sun each day.
Soil - The ideal soil for growing them is one with a neutral to slightly alkaline pH of 6.8 to 7.5 with an average to moderately rich, well-draining texture.
Watering - It is important to water your plants regularly in the summer, but do not overwater, as this can cause the leaves to yellow. The young plants should be watered thoroughly and often until the stems sprout, then once or twice a week thereafter.
