If you grow Asparagus, it’ll take more time to plant Asparagus from seed, but gratifying.

- Water regularly during spear production, tapering off as ferns mature. Control weeds with mulch or plastic covers.
- Let ferns grow all season the first year. Do not harvest; fertilize in spring and midsummer to establish the plants.

Common Asparagus Pests And Diseases
Asparagus beetles are a common pest that can damage asparagus spears and ferns. The adult beetles feed on the spears, leaving them pitted and scarred. The larvae attack the fernlike foliage on the plants. Monitor for the black and red beetles early in the growing season and pick them off by hand.
Fusarium wilt is a soil-borne fungal disease that causes asparagus plants to turn yellow and wilt. It spreads through contact between plant roots. Improve drainage around the plants and avoid overwatering to help prevent fungal diseases like fusarium.
Asparagus rust is another fungal disease that infects the plant’s leaves and stems. It causes orange-colored lesions and spots on the fern foliage. Remove any diseased plant debris and mulch around the plants to prevent spores from spreading.
Aphids are tiny sap-sucking insects that cluster on asparagus spears and ferns, causing stunted growth. Blast them off the plants with water and encourage natural predators like ladybugs.
Nematodes are microscopic worm-like parasites that attack asparagus roots, inhibiting nutrient and water uptake. Rotating crops, mulching heavily, and planting resistant varieties helps control nematodes. (Read Snake Plant Too Tall)
Where to Plant Asparagus
Choose a sunny area in your yard to plant asparagus. Asparagus, which grows in the form of asparagus crowns, is easy to grow and does best in well-drained soil between the pH range of 6.5 and 7.5.

Removing weeds from the soil will allow you to add organic matter, like compost or well-rotted manure.
For growing bare-root asparagus crowns in containers, pick a pot that is at least 18 inches deep to accommodate the lengthy roots. Before putting the crowns at the bottom of the pot, spread the roots out and cover them with soil. Place the crowns at least 12 inches apart for wholesome growth.
After planting, water the plants well and hydrate the soil in the area surrounding them to encourage strong development. Avoid letting the asparagus get too hot since it can cause the asparagus to lose its form.
How to Harvest Asparagus Spears

- How – Using a knife, Snap or cut spears when they are 6-8 inches tall. Always cut at ground level.
- When to stop – End harvesting when spears are pencil-thin. This allows the ferns to develop to nourish the plant fully.
- Frequency – During harvest season, cut the asparagus spears every 2-4 days as they emerge. New spears grow rapidly.
- Length – Stop cutting spears once they are pencil-width. This ensures robust plants the following year.
