‘Delight Cherry’ and ‘Delight Almond Blossom’ are an attractive supplement to the primula Danova series. These eye-catching varieties feature a red ring around a yellow center, set off by deep-green foliage. They may be used in pots, patio containers and garden beds.
Ideal for the early to mid-early season, they feature a habit and quality consistent with the Danova series.
Transplant plugs into 4-inch pots using a well-drained, sterile media. Optimum pH is between 6.0-6.5. A maximum of 3,000 foot-candles is recommended for primula production.
A well-balanced calcium nitrate–based formulation is recommended. Apply 100- to 150-ppm nitrogen as necessary to maintain an EC between 1.0 and 1.2.
In general, primula is not attractive to insects, but aphids, thrips, whiteflies and cut worms are major concerns. Primula requires cool conditions and high humidity to produce high-quality plants.
