Even the smallest garden has room for annuals. This can be no more than a few pots or hanging baskets of petunias or marigolds. In fact, these areas often need more color for interest.
Annuals can provide a succession of bloom throughout the year.
In southern Nevada annuals are planted several times during the year. Plant September-November for winter and spring color. Plant March-June for summer color. If the soil is very poor and rocky or consists mostly of caliche, remove it to a depth of 6 to 12 inches and replace with soil containing organic material. Organic matter should be added to an existing flowerbed every year.
