In this course, we will explore a wide range of horticultural practices with something to offer no matter our experience level or where we live. We will cover container gardening, aquatic gardens, ornamental and fruiting plants, bonsai, landscape design, and pest management. Each week, we will focus on a theme and examine design ideas, plant choices, and long-term care practices for success. Whether we garden on 10 acres or in an apartment, we will find plenty to learn and enjoy in horticulture.
