How to Regrow Asparagus

Hi there! Have you ever wondered how to regrow asparagus in your own garden? Well, you’re in luck! Here’s a quick guide on how to do just that.

To regrow asparagus, you’ll need to start with some fresh asparagus crowns. Begin by preparing a well-draining and sunny spot in your garden. Dig a trench that’s around 12 inches deep and about 18 inches wide. Next, create small mounds along the trench, spacing them about 12 inches apart. Place each asparagus crown on top of a mound, ensuring that the roots are spread out evenly. Gently cover the crowns with about 2 inches of soil, leaving the tops exposed.

In about two years, you’ll be able to harvest your delicious homegrown asparagus spears!

So, there you have it – a simple way to regrow asparagus in your own backyard. With a little patience and care, you’ll soon be enjoying the taste of fresh, homegrown asparagus. Happy gardening!

Preparing the Soil

Clearing the Area

Before you begin planting asparagus, it’s important to clear the area where you plan to grow it. Remove any grass, weeds, rocks, or debris that may be in the way. This will provide a clean and clear space for your asparagus bed.

Adding Organic Matter

To ensure that your asparagus plants have the nutrients they need to thrive, it’s essential to add organic matter to the soil. This can include compost, aged manure, or other organic materials. Mix the organic matter into the soil before planting to improve its fertility and water-holding capacity.

Testing pH Levels

Asparagus prefers a slightly acidic soil with a pH level of 6.0 to 7.0. Before planting, it’s a good idea to test the pH levels of your soil to ensure it falls within this range. You can purchase a soil pH testing kit and follow the instructions to determine the acidity or alkalinity of your soil. If necessary, you can make adjustments by adding lime to raise the pH or sulfur to lower it.

Choosing and Preparing Asparagus Crowns

Selecting Healthy Crowns

When choosing asparagus crowns, look for those that are firm, plump, and free from any signs of damage or decay. The crowns should also have healthy-looking roots. Avoid purchasing crowns that have dry or shriveled roots, as they may struggle to establish themselves in the soil.

Soaking the Crowns

Before planting, it’s a good idea to soak your asparagus crowns in water for a few hours. This will help to rehydrate the roots and improve their chances of successful growth. Simply place the crowns in a container of water and let them soak for a few hours before planting.

Trimming the Crowns

Before planting your asparagus crowns, you’ll want to trim any long or damaged roots. Use a clean pair of scissors or pruning shears to cut off any excess or unhealthy roots. This will encourage the crowns to focus their energy on establishing new roots and shoots once planted.

Planting Asparagus Crowns

Digging Trenches

To plant your asparagus crowns, start by digging trenches that are 6-12 inches deep and about 12-18 inches wide. Space the trenches about 4-5 feet apart, allowing enough room for the crowns to grow and spread out.

Creating Holes for Crowns

Next, create holes in the bottom of each trench to accommodate the asparagus crowns. Place the crowns in the holes, making sure that the buds (known as “eyes”) are facing upward. Space the crowns about 18-24 inches apart within the trench.

Spacing the Crowns

Proper spacing is important when planting asparagus crowns to ensure they have enough room to develop into healthy plants. Each crown should be spaced about 12-18 inches apart within the row. This allows the plants to grow without competing for resources and provides good air circulation to prevent disease.

Caring for Asparagus Plants

Mulching the Bed

After planting your asparagus crowns, it’s a good idea to mulch the bed with a layer of organic material. This helps to suppress weeds, conserve moisture, and regulate soil temperatures. Spread a layer of straw, wood chips, or compost around the plants, taking care not to cover the crowns.

Watering and Fertilizing

Asparagus plants require regular watering, especially during dry periods. Keep the soil consistently moist, but avoid overwatering, as this can lead to root rot. Fertilize the plants annually in early spring with a balanced fertilizer to provide them with the necessary nutrients for healthy growth.

Managing Weeds

Keeping the asparagus bed free from weeds is essential to prevent competition for nutrients and moisture. Regularly remove any weeds by hand or use mulch to suppress their growth. Be cautious when weeding, as asparagus plants have shallow root systems that can be easily damaged.

Harvesting Asparagus

Determining Harvest Time

You can start harvesting asparagus spears once they reach a height of around 6-8 inches. It’s important to only harvest a few spears initially to allow the remaining ones to grow and develop. As the season progresses, you can gradually increase the number of spears you harvest each time.

Harvesting the Spears

To harvest asparagus spears, carefully cut them at ground level using a sharp knife or pair of scissors. Hold the spear near the base and make a clean cut to remove it from the plant. Avoid breaking or snapping the spear, as this can cause damage and reduce its quality.

Removing Old Growth

Once the harvest season is over and all the spears have been harvested, it’s important to remove the old growth from the plants. Cut the stalks down to ground level and remove any debris or dead foliage. This will help maintain plant health and prevent the spread of diseases.

Dealing with Pests and Diseases

Common Asparagus Pests

Asparagus can be susceptible to pests such as aphids, asparagus beetles, and slugs. These pests can damage the plants and hinder their growth. Regularly inspect your plants for any signs of infestation and take appropriate measures to control and prevent further damage.

Preventive Measures

To prevent pest infestations and disease outbreaks, practice good garden hygiene. Keep the area around your asparagus bed clean and clear of debris and weeds. Avoid overwatering or overfertilizing, as this can attract pests. Additionally, plant companion plants that repel pests or attract beneficial insects to help control pest populations naturally.

Organic Pest Control Methods

If you’re dealing with pests in your asparagus bed, you can use organic pest control methods to manage the problem. Options include handpicking and removing pests, using insecticidal soaps or oils, or introducing beneficial insects such as ladybugs or lacewings to prey on the pests.

Overwintering Asparagus

Preparing Plants for Winter

Before winter arrives, it’s important to prepare your asparagus plants for the cold weather. Cut back the foliage to ground level once it turns yellow or brown, as this will help prevent diseases and pests from overwintering. Remove any debris from the bed to reduce the risk of diseases.

Mulching and Protecting the Bed

To protect the asparagus bed during winter, apply a layer of mulch over the crowns and around the plants. This will help insulate the soil and protect the crowns from frost. Straw or shredded leaves make good choices for winter mulch.

Cutting Back the Foliage

In early spring, before new growth emerges, you’ll want to cut back the old fern growth that was left overwinter. Trim the foliage back to about 2 inches above ground level. This encourages new growth and helps maintain plant health and vigor.

Dividing and Transplanting Asparagus

Signs for Dividing

After several years of growth, asparagus plants can become crowded, leading to smaller yields. Signs that your asparagus bed may need dividing include reduced spear size, declining plant health, or overcrowding. Dividing the crowns can rejuvenate the bed and promote better productivity.

Dividing the Crowns

To divide the asparagus crowns, carefully dig them out of the ground, taking care not to damage the roots. Gently separate the crowns into individual sections, ensuring that each section has enough roots attached. Discard any old or damaged crowns.

Transplanting to a New Location

If you want to transplant your asparagus to a new location, follow the same steps for dividing the crowns. Once the crowns are divided, prepare the new planting site by clearing the area and preparing the soil. Plant the divisions in the new location, taking care to provide adequate spacing and proper soil conditions.

Troubleshooting Common Issues

Thin Asparagus Stalks

If your asparagus stalks are coming up thin, it may be a sign of overcrowding or nutrient deficiencies. Consider dividing your asparagus bed to give the plants more room to grow. Additionally, make sure you’re providing proper fertilization with a balanced fertilizer to ensure the plants have the nutrients they need.

Yellowing Foliage

Yellowing foliage in asparagus plants can be a sign of nutrient deficiencies, pest infestations, or diseases. Check for signs of pests or diseases and take appropriate measures to manage them. Additionally, make sure you’re fertilizing your plants adequately with a balanced fertilizer.

Improper Fern Growth

Asparagus ferns play an important role in replenishing the plant’s energy reserves. If your ferns are not growing properly, it may indicate a lack of nutrients or insufficient sunlight. Ensure that your plants are receiving enough sunlight and fertilizer to promote healthy fern growth.
