At Sunburst Nursery we feel it is best to begin with healthy, disease resistant plants. Keep them watered, fertilized, and weed free for optimal vigor. Keep a watch out for pest/disease problems and control them as quickly as possible. If you can avoid using chemicals it is best to do so. If not, always read labels and follow instructions closely. Pay special attention to the warnings related to harvest time. Often there is a minimum waiting periods between the last application of pesticide and the harvest date.
