Petunias may be grown from seed sown early indoors and transplanted outside after frost, or from potted plants.
Sowing Seed Indoors:
- Sow petunia seeds indoors 8 weeks before last frost using a seed starting kit.
- Sow seeds thinly and barely press into seed starting formula. Do not cover with soil.
- Keep the soil moist at 70-75 degrees.
- Seedlings emerge in 10-14 days.
- As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this process because they will get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
- Thin to one seedling per cell when they have two sets of leaves.
- Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
- Transplant hardened-off seedlings to the garden after the frost.
- Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.
Planting Potted Plants in the Garden:
- Select a location in full sun with good rich moist, well-drained organic soil.
- Prepare the bed by turning the soil under to a depth of 8 inches. Level with a rake to remove clumps of grass and stones.
- Most plants respond well to soils amended with organic matter. Compost is a wonderful form of organic matter with a good balance of nutrients and an ideal pH level, it can be added to your planting area at any time. If compost is not available, top dress the soil after planting with 1-2 inches of organic mulch, which will begin to breakdown into compost. After the growing season, a soil test will indicate what soil amendments are needed for the following season.
- Plants should stand 6 to 12 inches apart in the garden.
- Dig a hole for each plant large enough to amply accommodate the root ball.
- Place the top of the root ball even with the level of the surrounding soil. Fill with soil to the top of the root ball.
- Press soil down firmly with your hand leaving a slight depression around the plant to hold water.
- Water thoroughly, so that a puddle forms in the saucer you have created. This settles the plants in, drives out air pockets and results in good root-to-soil contact.
- Use the plant tag as a location marker.
- Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating.
- Mulches also help retain soil moisture and maintain even soil temperatures. For annuals an organic mulch of shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
- Keep plants well-watered during the growing season, especially during dry spells. Plants need about 1 inch of rain per week during the growing season. Use a rain gauge to check to see if you need to add water. It's best to water with a drip or trickle system that delivers water at low pressure at the soil level. If you water with overhead sprinklers, water early in the day so the foliage has time to dry off before evening, to minimize disease problems. Keep the soil moist but not saturated.
- Until plants become established, some protection from extreme winds and direct, hot sunlight may be necessary. Good air movement is also important.
- After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer such as Flower-tone, as higher rates may encourage root rots.
- Remove spent flower spikes to encourage flowering and prevent seed development. Pinching the growing tips of plants can encourage bushiness.
- Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
- Remove plants after they are killed by frost in fall to avoid disease issues the following year.
- Cut scraggly petunia plants back by half in late summer to spur growth and encourage new flowers to form.
- Petunias make beautiful edging plants and also can be combined with other summer-blooming annuals in mixed plantings. They are superb in containers of all sizes and types, either alone or combined with other flowers.
- Petunias attract hummingbirds and moths to the garden.

Petunia, Shock Wave Coral Crush is rated out of 5 by 7.Rated 5 out of 5 by ashburncutie from THE BEST !!! My Favorite Petunia - Period !Date published: 2015-12-29Rated 4 out of 5 by anotherbeginnergardener from pretty mini petunias I was not expecting these to be mini petunias so was very disappointed at first. They have very small blossoms. Now that they have filled out they look very pretty. The color is not coral - it is more like the color in the photo. More of a very bright warm pink. They are so bright they are almost glow! Really pretty color. They are a bit on the expensive side. They have LOTS of blossoms so I guess that makes up for the flowers being small. Everyone comments how pretty they are. They have become my new favorite flowers and seem resistant to drought, heat and bugs. They are really thriving. I will buy them again if the plants are offered next year.Date published: 2013-07-05Rated 1 out of 5 by GardenerOfTheVille from Never Again ! For $12.95 plus shipping I could have bought a boatload of petunias locally, but I decided to try Burpee as I've known and trusted the name for years. WRONG !!!! What I received, after waiting forever, was six puny little plants, with just a couple blooms..... see photo, all SIX plants compared to my hand !! I've never been so disappointed. They've now been potted for almost three weeks in top brand potting mix and have hardly grown even though I've given them all the care necessary. NEVER will I buy plants from Burpee AGAIN !!! PS: The tomato plants were no better !!Date published: 2012-05-24Rated 3 out of 5 by Beasleysmomma from Too leggy Received these a little too leggy, I will have to cut them back so they don't break. And hope the color fades a little because they are more fushia than coral. And I guess I should have done my research because I thought these were regular patunias and not mini's.Date published: 2012-05-18Rated 1 out of 5 by MomCat from Disappointed in product I was very disappointed in the Petunia plants I ordered. They arrived in very poor shape, dry, spindly, half dead, not sure if they will thrive even after planting. You guys are great with seeds, I will not be ordering live plants from you again.Date published: 2012-05-14Rated 2 out of 5 by gardenpilot from Seed Starting Difficulties While these petunias certainly look beautiful, I have had horrid luck starting them from seed. I purchased the seed packet containing 10 pellets and only was able to get one plant to sprout. I have always had success starting other flowers, vegetables, etc. from seed but next time I think I will have to order the plants.Date published: 2012-04-07Rated 5 out of 5 by BurpeeGardenExpert from Visually Stunning Petunias Shock Wave petunias have been garden champions from the first year they were introduced to the American gardeners. They continue to be the ultimate source for color galore in pots and garden beds, on patios, and along the borders. Coral Crush is no exception. Millions of small flowers in coral with tiny but very bright cream to yellow throats will provide a visual feast to the eye. On top of that, the plants are extremely weather-proof, looking brilliant just a day after a punishing summer downpour.Date published: 2011-11-30
