Petunia Petunia 'Johnny Flame'

Water

Petunias require regular watering to keep the soil moist but not soggy. During active growth periods, watering Petunias 'Johnny Flame' deeply once a week is generally sufficient; however, they may require more frequent watering if conditions are very hot or dry. Each plant should receive about one gallon of water, ensuring that the entire root zone is saturated. Reduce watering in cooler or rainy periods to prevent waterlogged soil. Always avoid overhead watering to reduce the risk of disease and instead water at the base of the plant.

Light

Petunias thrive in full sunlight, which promotes healthy growth and abundant flowering. Place Petunias 'Johnny Flame' in a spot where they will receive a minimum of six to eight hours of direct sunlight per day. These plants perform best and flower most prolifically when they have ample exposure to intense light.

Temperature

Petunias prefer moderate to warm temperatures and will flourish when the daytime temperature is between 60 to 85 degrees Fahrenheit, though they can survive in temperatures as low as 40 degrees and as high as 90 degrees Fahrenheit. Ideal conditions are reached when night temperatures do not drop below 60 degrees, which encourages continued flowering and robust growth.

Pruning

Pruning Petunias encourages bushier growth and more blooms throughout the season. Deadhead spent flowers of Petunias 'Johnny Flame' regularly to promote new growth and remove any damaged or yellowing leaves. Perform a more extensive pruning or "pinching back" by trimming the stems by a few inches in midsummer to rejuvenate the plants and encourage a new flush of flowers.

Cleaning

As needed

Soil

The best soil mix for Petunia 'Johnny Flame' is a well-draining potting mix with a pH between 5.5 and 6.5. It should include a balance of peat moss, perlite, and loam to ensure proper drainage and aeration while retaining some moisture. Adding a slow-release fertilizer can also be beneficial for nutrient supply.

Repotting

Petunias, including 'Johnny Flame', should generally be repotted annually, especially if they are grown in containers. They appreciate fresh soil each year to renew nutrients and to accommodate the growing root system. If they are performing well, you can simply refresh the top layer of soil instead of a full repot.

Humidity & Misting

Petunias like 'Johnny Flame' prefer moderate humidity levels. While they can tolerate a range of humidity conditions, they are generally happiest with ambient humidity found in most homes and do not require any special humidity adjustments.

Suitable locations

• Indoor

  Provide bright light, regular watering, and monthly fertilizing.

• Outdoor

  Full sun, well-drained soil, regular watering, deadhead spent flowers.

• Hardiness zone

  9-11 USDA

Life cycle

The life of a Petunia begins with a seed, which germinates in warm, moist soil conditions, usually in the spring. Following germination, a seedling emerges, quickly developing true leaves and a root system. As the petunia grows, it enters a vegetative stage, with stems elongating and leaves expanding to capture sunlight for photosynthesis. After this period of growth, the plant enters the flowering stage, where 'Johnny Flame' Petunias display their characteristic vibrant, trumpet-shaped flowers, attracting pollinators for reproduction. These flowers eventually give way to seed capsules, which when mature, release seeds for the next generation. Lastly, as an annual plant, after setting seed, the Petunia 'Johnny Flame' completes its life cycle and dies, usually with the onset of colder weather.

Propogation

• Propogation time

  Spring-Early Summer

• Propogation: Petunia 'Johnny Flame', like other petunias, is most commonly propagated through seed. The ideal time to sow petunia seeds is in late winter to early spring, which allows the plants to reach a suitable size before being transplanted outside after the danger of frost has passed. To propagate by seed, scatter the tiny seeds on the surface of a well-draining seed starting mix in a tray or pots and gently press them into the medium. Do not cover the seeds with soil as they need light to germinate. Ensure the soil stays moist but not waterlogged and maintain a consistent temperature of around 70-75 degrees Fahrenheit (21-24 degrees Celsius) for optimal germination. Seedlings typically emerge in 7 to 14 days, at which point they can gradually be exposed to stronger light and eventually harder to outdoor conditions before planting out.
