Euphorbia Silver Swan

Euphorbia plants prefer a spot in full sun, meaning at least six hours of direct sunlight on most days, though some species can tolerate part shade.

Water whenever the top couple inches of soil feels dry from spring to fall when the plant is actively growing.

Temperature and Humidity. Most Euphorbia species can tolerate hot temperatures and prefer a warm environment with average daytime temperatures around 20 degrees. Feeding requirements vary by euphorbia species, but in general, all of them will benefit from some fertilizer. Adding compost or a balanced organic fertilizer to a new plant will help to promote healthy growth. After that initial feeding, many Euphorbia species will do fine with a weak liquid fertilizer applied throughout the growing season. For the amount to use, follow the product label instructions. Container-grown plants typically need more feeding than plants grown in the ground. And a plant that develops yellowing leaves at the bottom is one that's in need of feeding.
