i will be growing lots of veggies in my new backyard this spring. there's 2 good flat spots, one gets morning sun, the other gets afternoon sun. is half a day of full sun enough for vegetables? and which half is better?
If your garden spot is a mixture of some shade as well as full sun, here are the best rules-of-thumb:
Leafy vegetables, such as lettuce and spinach, will tolerate the most shade.
Root vegetables, such as carrots, radishes, beets and parsnips, need a half day of sunshine, doesn't matter which half.
Fruiting vegetables, such as tomatoes, cucumbers, peas, beans and squash need a full day of sun. Corn also benefits from full sun. A full day is 8-10 hours.
Some herbs can tolerate three-quarters of day of sun.
Kalicleo has good advice, but I'd like to add: when speaking of sun preferences in horticultural books, sun usually refers to morning sun...most plants that prefer sun will not grow as happily with only afternoon sun.
That said, the shadier parts of my veggie garden grow many things: all kinds of lettuces, chicories, and leaf cabbages, cutting celery, softwood culinary herbs (oregano, marjorams, basil), peas...and WEEDS! heh.
Mousa Calliope mentions sun in relation to when you water, and that jogged my winter-logged memory some.
Morning sun *is* generally better because it helps dry up the morning dew on plants. Likewise, we are usually advised not to water in the evening because it can create mildew. Of course, you can't tell Ma Nature what to do if *she* wants to water every evening!)
