New Guinea impatiens

New for 2011-12, ‘Pure Beauty Lavender Parfait’ and ‘Pure Beauty Vibrant Red’ boast large flowers and larger plant habit. Pure Beauty varieties are great for the landscape, and work well in pots and hanging baskets as well.

Choose a media with the following traits: good aeration, porosity between 5 and 15 percent, sterile and contains about 50 percent peat moss. Once plants have established, do not allow to dry excessively, which will result in damage to foliage and flowers.

Begin fertilizing two to three weeks after transplant. Choose a complete balanced fertilizer with minor elements. Pure Beauty requires a periodic feeding of 100 to 150 ppm constant liquid feed. During active growth, fertilizer levels may be increased to 200-ppm nitrogen.Maintain pH between 6.0 and 6.3. Optimum EC is below 2.0. Provide periodic clear water application if excess salts accumulate.

Maintain relative humidity below 70 percent and provide good air circulation to avoid problems with Botrytis. Establish crop with as much light as possible. Provide 5,000 to 6,000 foot-candles.
