Grandiflora petunias are of the most admired type, produce large flowers that are three or more inches across. They may be single colored or belle-dancer doubles type. Some have a pendulous, cascading habit that makes them more suitable for hanging baskets and window boxes, but most are upright plants that develop into large mounds of flowers which are twelve to fifteen inches tall. Multiflora petunias are just a little compact type. Their flowers are smaller than the grandifloras, but they make up for it with the sheer number of blossoms that are open at any given time.

Starting Petunias Indoors

One of the most popular annuals, petunias add mountains of color to garden beds and containers. These tough plants are capable of producing loads of blooms all season long and come in a wide variety of colors and patterns. While most petunias available nowadays are hybrids, they used to come in roughly two general classes, grandiflora and multiflora.

Grandiflora petunias were bred for their large, showy blooms while multiflora were bred for quantity over quality, producing numerous smaller blossoms. Petunias have always been known for their vast selection of colors and patterns, and now more than ever, the options seem almost endless. New varieties come out every year in novel shades and patterns. Countless color options are available, along with patterns like stripes, splashes, and even hearts.

The blossom size selection is quite diverse as well. Whether you're looking for a low-growing groundcover, a mounding type for containers, or a rambling wild plant to fill up some space, there is a petunia for every situation. One of the characteristics that makes petunias such a valuable and commonly used plant is their easy-going nature.

Modern varieties require very little maintenance and aren't too picky about growing conditions. As long as they are planted in well-drained soils , they typically won't have any problems. In anything less, there is a chance that they could have problems with rot and fungal issues.

Because petunias are such vigorous bloomers, they do need a substantial amount of nutrients to keep up their blooming power, so plant them in soils rich in organic matter. It is also beneficial to fertilize them fairly regularly throughout the growing season. It is important to plant petunias in full sun ; anything less can lead to fewer blooms and lankier plants.

Much like planting in wet soils, less than full sun can make plants more susceptible to fungal diseases. Part sun also allows soils to stay wet longer, increasing the likelihood of rot. Similar to flowering tobaccos , a close relative, petunias can attract some pesky bugs, especially during the heat of the summer, but rarely in large enough quantities to be of concern. Keep an eye out for whiteflies and aphids, as they are the most likely to show up.

Petunias are fairly low maintenance, but older varieties, especially seed-grown types, may require deadheading to keep up a constant display of blooms. Meanwhile, most new types are self-cleaning, so deadheading is unnecessary.

If they get too leggy, some petunias may also benefit from an occasional shearing back to help encourage a new flush of compact growth. Petunia 'Cascadias Bicolor Purple' is a heavy-blooming variety bearing purple flowers with a white star in the center.

Even without its fabulous scent, heliotrope would be widely grown in the garden. It has a distinctive scent—some say it smells like cherry pie, others say a grape ice pop.

As a bonus, this tropical plant, grown as an annual, bears big clusters of rich purple, blue, or white flowers. Heliotrope thrives in a spot with full sun and moist, well-drained soil.

It's a great container plant—try it in a window box or next to a doorway where you can enjoy it frequently. For the strongest scent, group several plants together where they can get afternoon sun, which helps release the fragrance. There are few gardens that don't have at least one salvia growing in them.

Most salvias don't like cool weather, so plant them outdoors after all danger of frost has passed.

How to grow petunias

With their trumpet-shaped flowers and petite stature, petunias Petunia x hybrida add a bright pop of color to garden beds and window boxes. Although most commonly grown from seeds, trailing and other cultivars of petunias also grow from cuttings. Growing petunias from cuttings is somewhat challenging since the newly rooted cuttings are extremely sensitive to excess humidity and poor growing medium. However, gardeners with the time and effort to invest in proper care can successfully root cuttings taken in mid-spring from actively growing petunias and produce healthy plants that bloom prolifically all summer.

However, you can ensure your petunias grow back after the winter by bringing them indoors or propagating new plants. Advertisement.

HOW TO GROW PETUNIA FROM SEED

Over the past nine years we have seen a percent increase in the number of cuttings imported into the United States. Growers have little influence on the stock plant management techniques and the methods employed to harvest, store and ship these cuttings, but they can improve how they propagate URCs to reduce rooting time and consequently increase profitability. In this article, we discuss how environmental factors can be adjusted to create a successful propagation environment for vegetative annual cuttings, with a focus on light intensity and daily light integral DLI during propagation. An ideal rooting environment for vegetative propagation is one that maintains hydrated cuttings, minimizes stress, prevents disease and promotes rapid root formation to support a growing and transpiring cutting. Most vegetative annual URCs can be fully rooted within weeks if proper environmental conditions are maintained. The critical environmental factors to manage during rooting are:.

Tips on Successful Young Plant Propagation

Petunias are popular for adding a splash of winter colour but if you sow them in the garden, frost can kill seedlings as they emerge. To provide the required warmth, shelter and moisture the easiest option is to use a mini greenhouse. This features a tray with a lid that has vents so you can control airflow. Sow the seeds in the tray and use a spray bottle to mist the potting mix with water, creating humidity. Replace the lid and position the mini greenhouse in a spot with lots of light but no direct sun. TIP Some greenhouses are called propagation units and have a built-in heater to regulate the soil temperature. Taking petunias from germination to garden bed takes about six weeks.

However, petunias can also be started indoors in late winter. Sow petunia seeds indoors about 10 weeks before the intended outdoor planting.
