How often should you fertilize asparagus?
Considered hardy in the U.S. Department of Agriculture zones 3 to 10, asparagus drains nutrients from the soil as it grows. However, starting with a nutrient-rich bed and fertilizing annually replenishes the nutrients so the plants have the necessary elements for fresh spear production each spring.
Should I fertilize my asparagus bed?
Generally, it is not necessary to apply fertilizer for an established asparagus crop until after harvest. In fact, delaying fertilization until after harvest can reduce early weed growth. For sandy coarse-textured soils, however, 20-25 lbs N/acre in the spring may be beneficial for spear development.
What is the best fertilizer for asparagus ferns?
Fertilizer. Feed asparagus fern with liquid or water-soluble all-purpose plant food diluted to half strength. During summer, container plants may need weekly feedings; otherwise, feed monthly.
How do you make asparagus grow better?
Choose a fertile, sunny, well-drained site with soil that holds moisture well. Late spring frosts can kill emerged spears, so find an area that is not low-lying or exposed to frost. Asparagus plants have deep root systems. Avoid areas with shallow soils, or soils prone to water-saturation.
Is bone meal good for asparagus?
Asparagus loves phosphorus. Composted manure, bone meal and rock phosphate are all good amendments to keep soil levels high in this nutrient.
Is chicken manure good for asparagus?
Asparagus likes full sun and a well-drained, deep friable soil that has had lots of well-rotted animal manure added to it. I like to dig a small trench about 20cm wide and 20cm deep. I then 1/2 fill it with a mixture of compost, cow, sheep and chicken manure.
Is cow manure good for asparagus?
If your soil is not rich and loamy, add about two inches of well-rotted manure or good aged compost. Or buy a bag of sheep manure from your nursery. Cow manure will do, but sheep manure has more nitrogen and nutrients.
Are coffee grounds good for asparagus plants?
Stocking up on coffee grounds for your vegetables, sowing peas, and planting asparagus are some of the spring activities for this year’s vegetable garden. Coffee grounds contain some major nutrients (nitrogen, phosphorus, and potassium) as well as some micronutrients, so put them to work in your garden.
