Maintenance Notes

No dead-heading necessary for continuous bloom. Moonlight Knight is cold tolerant and heat tolerant. He is also a "heavy drinker" and will prefer evenly moist soil. It will be quick to show drought stress, but should bounce back quickly once re-hydrated. In a hanging basket you should be prepared to water often, maybe more than once a day during warm weather. Plants are easier to keep moist when planted in large planters. Due to water needs Moonlight Knight is ideal for use in larger planters. In containers an application of continuous release fertilizer at planting is best. To help maximize performance use applications of a well-balanced water-soluble fertilizer (according to package directions) starting in mid-summer.

Moonlight Knight will also perform well in the landscape where she will function as an annual, full sun, groundcover.

While plants shouldn't need to be trimmed back, if the plant is taking over your walkway or is looking less than the best a trim can be administered at anytime. Use a sharp pair of scissors or pruning shears as needed.

A yearly application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.

Pinching and Growth Regulators

For all sizes of containers, pinch the liner 1–2 weeks after transplant; for containers larger than 6” and for hanging baskets, trim around the edge of the container as needed prior to spacing or hanging of the baskets.

A Sumagic spray at 5 ppm, 3 weeks after transplant is effective. Bonzi at 1 to 2 ppm is a good holding drench, do not apply too early - apply when the plant just starts over the edge of the pot. Topflor spray at 10 ppm is also effective. Snow Princess is also responsive to day/night temperature differential (DIF), and are shorter with a negative DIF.

Pest and Disease Management

Standard pest and disease practices as outlined in the notes.

Grower Tips

-Water early in the day so foliage is dry by nightfall to decrease disease pressure.

-Growing at too cold a temperature can cause purpling of the foliage.

-Yellow foliage is caused by drying the plant down past wilt stage.

This plant is much more vigorous and heat tolerant, continuing to bloom through the summer, than seed versions.

This plant is vigorous and can be pinched or pruned to shape.
