Fertilizer requirements: 100 to 200 ppm N and alternate with clear water. Leucanthemum are sensitive to high salt levels. Applying an occasional clear-water irrigation is recommended for maximum growth and root quality

Pinching requirements: None required; if a dominant shoot develops, pinching is recommended.

Growth Regulators: none required. White Mountain™ posses a well branched growth habit with thick stems creating a strong plant structure.

Disease and insect pests:
Mites, Thrip and Aphid
Avid™ foliar applications to control Mite and Thrip will burn foliage, turning the plants to black, looking like cold damage. It is best to use WP pesticides on Leucanthemum.

Pythium, Phytophthora
Roots of Leucanthemum are very sensitive to excessive drying, too wet or high salinity soils. Keep moisture at consistent level and do not over feed. Clear-water irrigation may be required now and then to reduce salt levels.
