How to Understand Plant Sunshine Requirements
You may be adding some perennials to your garden this summer or freshening up your containers and flower boxes as annuals go on sale. If you have had some difficulty growing flowers in the past, it may be because your plants have received too little - or too much - sunshine.
Here are common definitions for sunshine requirements you will find on garden center tags:
- Full Sun: The plant needs sunshine for at lease seven hours each day with no shade at all.
- Full Shade: The plant will thrive only if it has no direct sun for its growing season.
- Partial Sun: The plant needs at least four hours but no more than about six hours of sun.
- Partial Shade: The plant should recieve only about four-to-six hours of direct sunshine each day, and then be at least partially shaded the rest of the day.
