Growing asparagus

Growing asparagus can be one of the most rewarding experiences for any gardening enthusiast. This perennial vegetable not only adds a unique flavor to your meals but it also provides significant nutritional benefits.


With the right techniques and fertilizers, you can cultivate a thriving asparagus patch right in your backyard. In this guide, we will cover the essentials of how to grow asparagus and point you toward the best fertilizers to enhance your crop.


Understanding Asparagus


Asparagus is a delicate vegetable that requires time and care. Originating from Europe, it thrives in well-drained soils and prefers sunny locations.


Remarkably, asparagus can produce for 15 years or more, making it a long-term investment for your garden. Understanding its growth cycle and nutrient requirements is vital for a successful harvest.


Asparagus grows from crowns, which are typically one-year-old plants. These crowns are usually planted in spring when the soil temperature reaches at least 50°F (10°C). If you're eager to start your asparagus garden, consider purchasing high-quality crowns from a reputable nursery or online shop.


Many gardeners report that purchasing disease-resistant varieties can lead to healthier plants and increased yields.

Preparing Your Garden Bed for Growing Asparagus


Creating the right growing environment is essential. Select a sunny spot in your yard, as asparagus requires at least 6 to 8 hours of sunlight daily. Clear the area of weeds, rocks, and debris, then till the soil to a depth of at least 12 inches.


To assess soil quality, test the pH and aim for a range between 7.0 and 7.5. If necessary, adding lime can help bring your soil within this optimal range.


For improved soil fertility, incorporate plenty of organic matter such as rich compost or well-aged manure. Research shows that adding compost can increase soil nutrients by up to 50%.


Planting Asparagus Crowns


Once your garden bed is prepared, it’s time to plant the crowns. Create trenches that are about 12 inches deep and space them 3 to 4 feet apart. Water the crowns before planting to keep them moist. Place the crowns in the trenches and ensure that the roots are spread out before covering them with 2 to 3 inches of soil.


Adding a layer of mulch will help retain moisture and suppress weeds. As the asparagus grows, gradually fill in the trench with remaining soil as the shoots rise. Remember, it takes patience; typically, it takes 2 to 3 years before you can harvest your first crop.

Watering and Care


Consistent watering is crucial, especially during the first year. Asparagus needs about one inch of water weekly, particularly during dry spells. Be cautious not to overwater; soggy soil can lead to root rot, a common issue for many gardeners.


During the growing season, keep an eye on weeds, as they can compete for nutrients and water. Hand-pulling or applying mulch can be effective ways to control weed growth, allowing your asparagus plants to thrive without disturbance.


Fertilization for Healthy Growth


Properly fertilizing your asparagus is vital for their health. In the first year, focus on building soil fertility with organic matter and compost. As your plants mature, consider using a balanced fertilizer to ensure they receive the nutrients they need.


Recommended Fertilizers


  1. Organic Compost: Enriches the soil and improves its structure, making it more conducive for asparagus growth.

    Recommended product: Vego Kitchen Composter


  2. Bone Meal: Excellent for root development; applying during planting can boost early growth rates.

    Recommeded Product: Espoma BM24 Bone Meal


  3. Fish Emulsion: A natural source of nitrogen that is perfect for early spring applications when the plants begin growing.

    Recommeded Product: Alaska Fish Emulsion


  4. Organic Slow-Release Fertilizer: This should be applied in early spring for a consistent supply of nutrients throughout the growing season.

    Recommeded Product: Earth Science – Moorganite


  5. Green Manure: Utilizing cover crops can enhance soil vitality; many gardeners mix clover or vetch into their soil.



By applying fertilizers at the right times, you can enhance growth and help ensure a bountiful harvest. Always follow package instructions and keep an eye on your plants' health to avoid over-fertilization.

Harvesting Your Asparagus


Your patience will be well rewarded when it's finally time to harvest! Generally, you should wait until the third year to start picking any asparagus spears. In the third year, you can harvest for about 2 to 3 weeks. In subsequent years, this can extend to 6 to 8 weeks.


Cut the spears when they reach approximately 6 to 8 inches tall and before the tips begin to fern out. Always use a sharp knife or garden shears to ensure a clean cut, which can prevent damage to the plant.


Happy Gardening!


Growing asparagus can be a fulfilling and enjoyable endeavor for anyone who loves gardening. By selecting the right spot, adequately preparing your garden bed, and applying the recommended fertilizers, you can cultivate a vibrant asparagus patch that yields delicious spears season after season.


Whether you are a seasoned gardener or just starting out, growing asparagus offers an exciting opportunity to enhance your skills. Get ready to roll up your sleeves and enjoy the rewarding experience of cultivating your very own asparagus garden! Happy gardening!
