NEW GUINEA IMPATIENS CONTINUED OUTDOOR GROWING SCHEDULE Infinity New Guinea Impatiens finish best in a controlled greenhouse environment, but can be moved outdoors after all threat of frost has passed (late May to early June in Michigan). This recommendation is based on average spring weather and should be adjusted for unseasonably severe or unseasonably mild conditions. OTHER TIPS Growing at an average daily temperature of 68 F will produce larger blooms and earlier flowering plants. Maintain higher humidity levels if possible to encourage earlier and larger blooms, 75% optimum. Do not keep too wet or overfertilize. This will affect plant growth and delay flowering. Maintain soil pH levels above 6.0; 6 - 6.5pH is optimum. Fungicides with the active ingredient fludioxonil (Medallion®) can have a PGR effect on New Guinea Impatiens and should be avoided. The rates and chemicals listed are based on our southeast Michigan growing conditions, and are not recommended for nationwide application. Please adjust the rates and spray applications to your location and facility. 41
