Every spring you start over. New seeds. New transplants. New soil prep. New money.<\/p>\n
A perennial food garden eliminates all of it. One weekend of planting produces food for decades without reseeding, replanting, or starting over.<\/p>\n
Asparagus produces for twenty-five years from a single planting. Blueberries bear fruit for thirty and increase yield every season. Raspberries spread on their own and fill gaps without being asked. Rhubarb outlives the gardener who planted it. Walking onions topset and replant themselves \u2014 literally zero effort.<\/p>\n
One planting. Decades of harvest.<\/p>\n
Layout for a ten-by-twenty plot:
\n– Back row on the north side (in the Northern Hemisphere, opposite in the Southern) \u2014 blueberry bushes and elderberry for height
\n– Second row \u2014 asparagus bed running the full width, one trench gives you a twenty-five-year harvest
\n– Center \u2014 raspberry and blackberry canes with simple wire support
\n– Front rows \u2014 rhubarb crowns, strawberry groundcover, perennial kale, sorrel
\n– Edges \u2014 rosemary, thyme, oregano, chives, walking onions
\nYear one investment runs roughly a hundred fifty to two hundred fifty dollars for plants, crowns, and bare-root stock.<\/p>\n
Asparagus and blueberries need two to three years to hit full production. Raspberries, herbs, rhubarb, and strawberries produce meaningful harvest in year one. By year three the entire plot is producing at full capacity with almost no input.<\/p>\n
Maintenance is one spring mulch and one fall compost top-dress. That\u2019s it.<\/p>\n
The most productive garden is the one you plant once and never have to start over.<\/p>\n","protected":false},"excerpt":{"rendered":"
