Asparagus is a delicious and nutritious vegetable that can be enjoyed for several weeks each spring. But if you’re impatient for a harvest, you may be wondering how to grow asparagus quickly. While you can’t force asparagus to grow overnight, there are several things you can do to speed up the process and enjoy fresh spears sooner.
Start with the Right Asparagus Crown
The key to growing asparagus quickly is starting with healthy, vigorous crowns. Asparagus crowns are the underground stems that produce the shoots you eat. When choosing crowns, look for ones that are firm, plump, and free of damage. You can purchase crowns from reputable nurseries or online retailers.
Prepare the Soil for Asparagus
Asparagus prefers well-drained, fertile soil with a pH of 6.5 to 7.0. Before planting, amend the soil with compost or aged manure to improve its structure and nutrient content. If your soil is heavy clay, you may want to incorporate some sand or perlite to improve drainage.
Plant Your Asparagus Crowns Deeply
When planting asparagus crowns, it’s important to bury them deep enough. This will encourage the roots to develop and produce strong shoots. Dig a trench about 12 inches deep and 18 inches wide. Space the crowns 18 to 24 inches apart in the trench. Place the crowns in the trench so that the growing points are facing up. Cover the crowns with soil, leaving the growing points exposed. Water the crowns thoroughly after planting.
Water Regularly and Deeply
Asparagus needs consistent moisture to thrive. Water deeply and regularly, especially during the first year after planting. The soil should be kept moist but not soggy. Mulching around the plants can help to retain moisture and suppress weeds.
Fertilize Regularly
Asparagus is a heavy feeder and needs regular fertilization to produce abundant spears. Apply a balanced fertilizer, such as 10-10-10, every few weeks during the growing season. You can also use compost or manure as a natural fertilizer.
Protect Your Asparagus from Pests and Diseases
Asparagus is susceptible to several pests and diseases. To prevent problems, inspect your plants regularly for signs of infestation or disease. Control pests with insecticidal soap or neem oil. If you notice any signs of disease, remove the affected plants and dispose of them properly.
Harvest Your Asparagus
Asparagus is ready to harvest when the spears are about 6 to 8 inches tall. Use a sharp knife or pruning shears to cut the spears at ground level. Harvest spears every few days to encourage continued production. Stop harvesting in late June or early July to allow the plants to store energy for the next year.
Keep Your Asparagus Healthy for Years to Come
Asparagus is a perennial vegetable that can produce for 10 to 15 years with proper care. To ensure a long-lasting harvest, follow these tips:
- Continue to fertilize regularly.
- Water deeply during periods of drought.
- Control pests and diseases.
- Avoid harvesting spears after mid-July.
- Apply a layer of mulch around the plants in the fall to protect the crowns from frost.
Asparagus in a Hurry: Final Thoughts
Growing asparagus quickly requires a bit of patience and attention to detail. By starting with healthy crowns, planting them deeply, and providing them with consistent moisture, nutrients, and pest control, you can enjoy fresh asparagus spears sooner. Remember, asparagus is a long-term investment, and the rewards will be worth the wait.
