How To Grow Asparagus in your Survival Garden - Growing perennials is a sustainable, practical gardening technique that will provide you with food for years. But there are a few things you need to know about growing your asparagus crop like how to avoid pests, diseases and weeds, how to properly prepare the beds and ultimate how to harvest them.
Allow asparagus to grow without harvesting the year it is planted. In the second year, harvest spears that are 1/2-inch in diameter, but only for two weeks. Cut or break off 7- to 9-inch-long spears with tightly closed tips. In subsequent years, harvest for five to eight weeks, then allow the shoots to develop into ferny growth to build up the roots for the following year's crop.
