April Care for Perennial Vegetables: Asparagus and Rhubarb

by

April is a crucial month for gardeners focusing on perennial vegetables like asparagus and rhubarb. Proper care during this time ensures a healthy harvest for years to come. Understanding the specific needs of each plant helps maximize growth and yield.

Preparing Soil for Asparagus and Rhubarb

Before planting or resuming care, test your soil’s pH and nutrient levels. Both asparagus and rhubarb thrive in well-drained, fertile soil with a pH between 6.0 and 7.0. Incorporate organic matter such as compost or aged manure to enrich the soil. This preparation promotes strong root development and vigorous growth throughout the season.

Asparagus Care in April

In April, asparagus crowns begin to emerge from dormancy. To support healthy growth:

  • Clear any winter mulch carefully to avoid damaging emerging spears.
  • Remove weeds around the bed to reduce competition for nutrients.
  • Apply a balanced fertilizer, such as 10-20-10, around the plants to promote spear development.
  • Mulch lightly with straw or shredded bark to retain moisture and suppress weeds.

Avoid harvesting spears in the first year to allow the plants to establish a strong root system. Regular watering is essential, especially during dry spells, to keep the soil consistently moist.

Rhubarb Care in April

Rhubarb crowns start to grow actively in April. To ensure a healthy crop:

  • Remove any winter mulch to allow new shoots to emerge.
  • Apply a nitrogen-rich fertilizer, such as blood meal or composted manure, to support lush leaf growth.
  • Divide overgrown crowns if necessary, ideally in early April, to rejuvenate the plants.
  • Remove flower stalks as they appear to direct energy into leaf production.

Maintain consistent watering, ensuring the soil remains moist but not waterlogged. Mulching around the base helps retain moisture and suppress weeds.

Additional Tips for April Garden Care

Monitor for pests and diseases, which can become active as temperatures rise. Keep the garden tidy by removing debris and dead foliage. Regularly check for signs of stress or nutrient deficiencies and adjust fertilization accordingly.

By following these April care tips, gardeners can ensure their perennial vegetables remain vigorous and productive, providing fresh harvests for many seasons to come.
