Site Selection and Soil Preparation
Asparagus thrives in well-drained, sunny locations. Choose a spot that receives at least 6 hours of sunlight daily. Prepare the soil by:

Planting Your Asparagus Crowns
Asparagus is typically planted from crowns, which are the root systems of the plant. Follow these steps for planting:
1. Prepare the Planting Area: Dig a trench 15-20 cm deep and 30-40 cm wide.
2. Spacing: Space crowns 30-45 cm apart in the trench.
3. Planting Depth: Place crowns with the buds facing upward and cover them with 5-10 cm of soil.
4. Watering: Water thoroughly after planting.

After the harvest season, allow your asparagus plants to rest and rebuild their energy reserves. This ensures a bountiful harvest in the following years.
