Lime sulfur is a mixture of calcium hydroxide and sulfur. In horticultural dormant sprays, lime sulfur is usually mixed with an oil, like mineral oil, to make it stick to plant surfaces. These horticultural oil sprays contain a high concentration of lime sulfur that is only safe to use on dormant plants because the sulfur can burn leaf tissues. Lime sulfur can also be mixed in much weaker concentration with water for use when plants have leafed out.
