Sunlight is a very important factor to consider when planning your garden, for it is sunlight that transforms water and carbon dioxide into the sugar that your plants use for food. The sugar is used in forming new cells, and in developing fruit and flowers. A general rule is that the larger the sunlight intensity the greater the production of sugar. Without sufficient light even a plant that looks healthy will not produce flowers or fruit.
Many crops are not affected by the length of the day, but for many crops it plays a large part in regulating when they mature and flower. So how much sunlight is needed? Vegetables that are grown for their fruit need a minimum of 6 to 8 hours of direct light each day. Crops that are grown for their roots and leaves will do ok in light shade. Root crops like beets and carrots will store energy before they flower and do pretty well in partial shade.
To make the most of your garden light don’t put it in the shade of buildings or trees. Trees not only shade your garden, but can have large root systems that may extend underneath and compete for nutrients, especially keep your garden away from walnut trees as they produce iodine which will stunt or kill vegetable plants. A good idea is to observe the area you plan on gardening throughout the day and mark the limits of the cast shadows.
Although most vegetables need full sunlight, young or newly transported plants need protection from the direct sunlight. You can either plant large plants to act as a screen or erect temporary screens.
