Answer: Keeping the soil moist is a key requirement for successfully growing New Guinea Impatiens. You can improve the soil prior to planting by incorporating organic matter to help loosen your heavy, clay soil. Begin by spreading 4"-6" of aged compost, leaf mold, peat moss or aged manure over the bed and digging it in to a depth of 6"-8". Then plant your Macarena's. To help your new plants thrive, fertilize monthly with a diluted liquid fertilizer. 'Spectra' hybrids, including 'Sweet Sue' and 'Tango' can grow to 2' high. You can pinch your plants back once or twice when they're young to encourage side branching, but they won't require additional pinching during the growing season.
