Wave Petunia Instructions & Care

The best use for Wave Petunias:

  • Wave Petunias can be planted in just about any sunny location.  They have outstanding garden performance, plus they also work well in hanging baskets, large containers and window boxes.

A few things to remember when planting Wave Petunias:

  • Plant Wave Petunias after the last spring frost when night temperatures stay above 40 degrees consistently. We recommend keeping them inside in a sunny location until then, or put them outside in sun during the day, and bring them back in at night.
  • Plant in full sun (minimum of 6 hours per day).
  • The more established the plant, the more heat tolerant it is.  If you can, plant your Wave Petunias early enough to enable them to establish strong root systems before high temperatures set in.
  • Maintain the same plant depth as the original pot or pack.
  • Space Wave Petunias 12 to 24 in. apart in garden beds.
  • For lush, full container displays, place 3 plants in a 10-12 in. container, hanging basket or patio planter.  Larger containers will require additional plants for an attractive, proportioned display.
  • Using mulch protects the roots and conserves moisture, however, Wave Petunias form their own solid mat of color as they grow.


  • Don’t let your Wave Petunias dry out between watering.  They need plenty of water, but keep in mind that the soil in beds and containers must be well drained and containers dry out faster than in-ground beds.  If possible, water your plants in the morning so the foliage dries before evening.
  • Wave Petunias are heavy “feeders”.  The full potential of Wave Petunias will not be realized from hungry plants.  Apply a liquid fertilizer every 10-14 days.
  • Wave Petunias are low-maintenance; you don’t have to cut the plants back or remove dead flowers.  The faded blooms will dry up and drop off the plants on their own, with more appearing continuously all season long.
