Can answer questions about spring and summer bulbs: selection, soil preparation, planting, fertilizing, designing with bulbs. I can also give references where to buy the bulbs and how to store them. Besides the typical bulbs (tulips, daffodils, amaryllis, lilies etc) I can also answer questions about other geophytes, such as tuberous begonia, dahlias, etc. When to start indoors, light requirement, etc. My experience is in cool season areas, but I can answer questions about warm season areas if given time to research matter.

Experience

Have worked with various bulbs (spring and summer bulbs). I am presently an allexpert advicer on the lawn message board also.
