General Planting Tips for April Flowers

  • Check your frost dates: In regions with late frosts, sow seeds of hardy annuals and perennials first, and wait to transplant frost-tender species until the forecast is reliably warm.
  • Prep your soil: Amend with compost or balanced fertilizer before planting for richer blooms and stronger plants.
  • Water deeply: Early spring root growth is essential, so keep soil moist but not waterlogged.
  • Mulch: Apply an inch of organic mulch to retain soil moisture, regulate temperature, and suppress weeds.
  • Deadhead spent flowers: Remove faded blooms to encourage plants to keep producing flowers well into summer.

Companion Flowers for Pollinators

Many of these April-planted flowers, including coneflower, alyssum, salvia, and calendula, are magnets for bees, butterflies, and other pollinators. Incorporating a range of flower shapes and colors will support a healthy ecosystem and improve yields for nearby fruits and vegetables.

Suggested Layouts: Beds, Borders, and Containers

  • Borders: Layer taller varieties like coneflower, cosmos, and snapdragons at the back; use medium-height plants such as zinnias and salvias in the middle; and tuck alyssum or pansies at the edges for a lacy trim.
  • Containers and Baskets: Combine trailing petunias and geraniums with upright snapdragons and pansies for a dynamic display in planters.
  • Cottage Mix: Direct sow nigella, bachelor’s buttons, calendula, sweet William, and cosmos together for an informal, pollinator-friendly patch.
