General Information

Plant Care Instructions By Steve Brigham

Asparagus are easy to grow in Southern California. Although it\'s best to wait until the plants\' third spring to start harvesting, your plants will continue to produce heavily each spring for 10-15 years after that. Good soil preparation before planting is essential, but little maintenance is necessary. If you grow an \"all male\" variety such as \'UC 157\', \'Jersey Giant\', or \'Jersey Knight\', you\'ll avoid unwanted volunteer seedlings which may differ in quality from the original plants.

Is Indoor Plant?
