  • Decide what flowers to grow.

  • Choose showy, large flowers; small, delicate flowers; brilliant blazes of color; soft pastels.
  • Look for varieties with long stems; some need staking.

  • Purchase seeds and plants early; plant after last frost.

  • Seed packets will have planting depth and directions.
  • Plants transplanted in the ground need water immediately.


  • Thin newly emerged plants if too thick.
  • Supplement with water if needed.
  • Fertilize twice a month with a well balanced fertilizer.
  • Add 2 to 4 inches of mulch when plants are 6 inches tall.
  • Removing dead blooms will promote longer blooming.
  • Keep weeds out of flower bed.
  • Stake flowering plants if needed.

  • Scissors or knife
  • Vases with water
  • Floral preservative (optional)


  1. Gather materials. Select flowers and vase of choice.
  2. Fill vase half full of water.
  3. As stems are selected, remove any foliage that will be below the water line.
  4. Recut stems at a diagonal as this allows for a larger surface area and greater absorption of water.
  5. Start by placing 6 to 8 stems of greenery in a criss-cross fashion to create the base.

  6. Select large flowers as focal points and measure the flowers against the vase to know where to cut the stems. Stagger the height to fill the vase and create an eye-catching design.
  7. Fill in with smaller, secondary flowers.
  8. Add filler to soften the open spaces and round out the arrangement.
  9. Replace water every other day and use floral preservative if needed.
