Petunias grow in average well-drained soil and full sun to partial shade. Afternoon shade protects these perennials from the intense Sacramento summer-sun. Deadhead petunias for continued growth. Water every day during hot weather. They tend to get leggy in extreme heat, so you may need to trim them back by mid-summer. They'll reward you with a profusion of new blooms.

In Sacramento, perennial geraniums do best in partial shade to protect them from the intense sun rays. Keep them moist during hot weather. They come in shades of red, pink, lavender and white.
