Plants that grow in full sun are the largest group of all the plants and require at least 6 to 8 hours of sun a day.
Plants have adapted to a range of different light intensities. Some require large amounts of sunlight, while others just a little sunshine.
Planting in full sun can vary depending on your climate. Full sun in the heat of Arizona or Texas and full sun in Vermont or Oregon will be very different.
Sunlight Requirements For Plants
Insufficient sunlight is often the cause of plants not doing well. Full sun requirements mean at least 6 to 8 hours of sunlight a day to perform well.
Plants that require partial shade or dappled shade require 3 to 4 hours.
Plants for shade will thrive with 2 hours of direct sunlight a day.
How To Measure Full Sun
To measure how much sun a part of your garden gets, start early in the morning and note the amount of sunlight in that particular space.
Keep an hourly record of whether that area is getting sun, dappled sun, or shade.
Remember that the sun changes position at different times of the year. Keep an eye on that area and map it every few weeks throughout the year. Noting the annual amount of sun each area of your garden receives will determine your plantings during the four seasons.
Can Full Sun Plants Grow In Shade
Remember to read the labels of each plant and note their sun requirements.
Some plants which prefer full sun will still grow well in partial shade for a few hours a day. They may get "leggy" looking for sun or not flower as profusely.
