Plan your garden by first listing your favorite flowers, then research additions to floral arrangements you may not have thought of by looking through gardening books and magazines. Pay close attention to bloom times, as you will want a variety of flowers to bloom at the same time to create your arrangements.
Prepare your garden space and plant the flower seeds you have chosen in groups. Create your groups based on which flowers you will likely arrange together. The rule of thumb is tallest to the back and shortest to the front for an appealing look. This works for gardens grown in rows or scatter-type gardens, which can be any shape or size (a typical flower bed is a scatter design).
Add interest to your garden and arrangements by growing nonfloral additions, such as fragrant herbs or greenery, that can round out both your cutting garden and floral arrangements. Plant them mixed within the flowers or in groups by themselves.
Cut your blooms just as they begin to or right before they fully open. As your flowers continue to bloom multiple options for your arrangements will become continually available. Trim the flowers to varying heights and arrange as desired. Replace with a new selection of flowers as they begin to fade.
