The first brand of trailing (hanging) petunias to hit the market was Surfinia. Petunias called Surfinia are wonderful trailing plants that can withstand rain and are grown from cuttings.
Where should Surfinia petunias be planted?
Petunia Surfinia is an annual that does best in full sun. For optimal blooming, a bright location is advised because Surfinia requires a considerable amount of light to be able to flower. After the risk of frost has passed, midspring or early summer are the best times to sow your flower.
Do Surfinia petunias grow year-round?
One of the most popular summer bedding plants in our region is the petunia, which blooms from mid-summer until the first hard frosts of autumn. Their profusion of flowers fills gardens with wonderful color.
The trailing kinds liven up hanging baskets and flow down the edges of containers, while the compact, bushy varieties are ideal for planting in beds and borders.
Petunia flowers come in a vast array of colors, single and double blooms, smooth or ruffled petals, solid single, striped, veined, or picotee-edged colors, and even fragrance. The issue of ancient petunia types turning to mush in a wet summer has also been eradicated by recent breeding.
Petunias are perennial, despite the fact that the majority of bedding kinds are produced from seed annually as annuals. The perennial trailing varieties, like Surfinias, are cultivated from cuttings or young plants.
Cultivation
Although they will tolerate a little moderate shade during the hot, sunny summers, petunias like to be cultivated in full sun. They thrive on soil that is rich in nutrients, moist but well-drained. To keep moisture in sandy soils that drain very well, add lots of organic matter to the soil, such as garden compost, well-rotted manure, or other soil-improving materials.
Petunia varieties
Grandifloras, which have larger flowers, or multifloras, which have smaller flowers and are more resilient to rain, are the two varieties used as bedding.
The Surfinia, Wave, Tumbelina, Supertunia, and Cascadia series of petunias spread or trail.
Sowing petunias
Petunias can be grown from seeds inside with warmth in cell trays, seed trays, or tiny pots at a temperature of 18 to 24C as an annual or bedding plant (65-75F).
When plants are big enough to handle, prick them out into cell trays or tiny pots and let them continue to grow at a temperature of 50 to 65 degrees Fahrenheit (10 to 15 degrees Celsius) in good light.
Before planting the seedlings outdoors once all danger of frost has passed, gradually acclimate them to outdoor circumstances for 7 to 10 days.
Young petunia seedlings are available from garden centers and mail-order suppliers in the late winter/early spring if you don’t have the resources to grow them from seed.
Planting petunias
Make a good-sized planting hole that can readily fit the rootball. Fork in a layer of organic material, such as compost or planting compost, at the bottom of the hole.
Place the rootball in the planting hole, adjusting the planting depth (except for hardy fuchsias) until the top of the roots is level with the soil surface and the rootball is planted at the same depth as it was growing. Fill the planting hole with the excavated soil after adding more organic matter to it. Put some granular general feed on the soil and thoroughly wet it in. The soil can be kept moist and weeds can be controlled by adding a 5-7.5cm (2-3in) deep mulch of well-rotted garden compost or something similar over the soil. If you have a warm greenhouse, you can plant baskets and containers in the spring, let the plants mature, and then move them outside in late May or early June. You’ll have flowers earlier in the summer if you do this.
How to care for petunias
When there are protracted dry spells in the summer, water the soil frequently to keep it moist. Plants in containers will require routine, possibly daily watering with the intention of maintaining evenly moist compost. But be careful not to overwater, as this may make the plants leggy and produce few blossoms.
To ensure a steady supply of blossoms throughout the summer, feed your plants with a liquid plant food on a regular basis. Up to the first autumnal frosts, a high potash liquid plant feeding will promote more, better blooms.
The show will last longer if faded blooms and any sprouting seed pods are removed. Cut back straggly plants severely before feeding them with a liquid plant food to encourage fresh new growth and an abundance of blossoms.
Fall is the greatest time to dig up and compost bedding petunias that have been harmed by frost.
Overwintering petunias
Trailing perennial kinds can be pruned back severely in the fall, cleaned up by removing any dead or broken growth, and then gently lifted. They should be overwintered in a bright, frost-free location, preferably a greenhouse or cool conservatory, in pots just large enough to hold the rootball and with some fresh potting compost around the sides.
Propagating perennial petunias
Cuttings taken in March or April from plants that overwintered or in August or early September from perennial, trailing kinds can be used to create new plants.
Select young, robust, vigorous stems that aren’t in bloom. Cut back one or two stems at the back of the plants severely to promote vigorous regeneration if you are unable to locate adequate growth. collect clippings 7.5–10 cm (3–4 in) long and positioned immediately below the node or junction of a leaf. In pots of gritted cuttings compost, place five or six cuttings at the base of the lowest leaves after removing the leaves from the lower two-thirds of the stem. Put the pots in a propagator or a plastic bag and set them somewhere with good light—but not in the sun—to root.
In two to three weeks, the cuttings should have taken, at which point they can be potted up separately and continued to grow.
Petunia Surfinias are resilient.
Overview:
Although petunias are native to Argentina, the majority of the varieties marketed now are hybrids created for particular uses.
They are a well-liked bedding plant with broad trumpet-shaped flowers in a rainbow of colors and spreading, hairy, and slightly sticky foliage.
The flowers can have a mounding or cascading habit, be solitary or double, striped, veined, or self-colored, and occasionally they may even be scented.
Grandiflora and multiflora types are the most popular variations; grandiflora has larger blossoms, while multiflora types keep up better in wet weather.
These have gained popularity since they don’t require deadheading and may be used as groundcovers, bedding plants, or as plants that trail in pots.
In particular, if they are routinely deadheaded to lengthen the flowering season, all of the plants in this series are prolific bloomers and will bloom all summer long.
Both varieties are common plants for hanging baskets, window boxes, tubs, and borders; they are typically cultivated as half-hardy annuals.
The many garden cultivars demand a sheltered sunny setting and light, well-drained soil. They grow to a height of 200-400mm (8″-15″) and flower from late June till the first frosts.
The growth of leaves will be favored at the price of flowering due to overly rich soil, excessive shadow, and wetness.
The wind and strong rain might harm the fragile blossoms, so look for kinds that can withstand the elements.
Cultivation:
Week 10:
Plant seeds in the seed compost and allow them to germinate at 20 C. (68F).
Week 11:
Week 14:
Grow the plants for a few more weeks at 12°F or lower, then gradually harden them off in a frost-free coldframe until planting time.
When the plants are 50-75mm (2″-3″) tall, pinch out the growing tips to promote a branching habit.
Around week 18:
Make sure to remove the seed pod after deadheading, and do the same if any petals have fallen off.
Week 23:
Although they thrive in full sun, petunias may also tolerate partial shade, especially in hotter climates.
They are drought-resistant and tolerant, but they don’t like it when it’s dry for a long time or when it’s too wet either.
Water them frequently to keep them from drying out or becoming stressed, and after they start to bloom, feed them every few weeks with a high-potash fertilizer.
Petunia plants may cease setting blooms in extreme heat, but they will resume when the temperature drops.
Diseases and Pests:
Petunias are often trouble-free, with the possible exception of prolonged wet weather when they may develop grey mold or root rot.
Can Surfinia endure the winter?
A
The Surfinia petunia is a perennial plant with numerous variants. Overwinter them in a lightly heated greenhouse where the temperature does not drop below 7 C to keep yours safe (45 F).
The number of Surfinias in a hanging basket
The typical rule for hanging baskets is to use one plant for every inch of the basket’s diameter, or 12 plants per 12 inch basket. For larger plants like geraniums (Pelargoniums), Surfinia petunias, culinary herbs, and fuchsias, you only need five plants per 12-inch hanging basket.
What you must do is as follows:
- 1. To keep your empty basket steady as you plant, place it on a bucket.
- 2. Use sheet plastic covered in a layer of straw or hessian to line wire hanging baskets instead of buying pre-cut liners. Any material that extends past the basket’s rim should be cut off.
- 3. To accommodate trailing plants, cut a series of 5 cm (2 inch) slits around the sides of the basket. Use a plastic hanging basket or our polypropylene basket with pre-cut holes to avoid the effort of lining your basket.
- 4. Add controlled-release fertilizer and water-retentive granules to a compost that serves many purposes. By feeding your plants during the growth season, you can prevent your pots from drying out too rapidly.
- 5. Fill your basket with compost until the compost layer is even with the side slits. To remove any air pockets, carefully press the compost into the ground.
- 6. From the inside, push your trailing plants through the slits “head-first.” Before guiding your plants through the perforations, cover them in polythene to safeguard the tender new growth. Place the plant so that the leaves are on the outside of the basket and the root ball is resting on the compost surface.
- 7. After you have stuffed every slit, carefully pry the plant roots out. More compost should be added to the area around the roots, filling the basket to within 5 cm (2 inches) of the rim.
- 8. Add extra trailing plants to the basket’s rim.
- If you place these so that they grow between the plants below, your form will be more evenly distributed overall. Fill in the center of the basket with erect, bushy plants.
- 9. Spread compost around your plants, being sure to leave a gap of 2.5 cm (1 inch) below the lip of the basket so the compost won’t wash away when you water.
- 10. After thoroughly moistening your basket with a fine-rose watering can, hang it in the desired location or place it in the greenhouse.
The rate of Surfinia’s growth.
Suntory released Surfinia petunias, the first petunias to be propagated vegetatively, sparking a revolution in vegetative annuals around the world. Surfinias, a robust and vivacious plant, revolutionized the petunia genus, which had previously been dominated by compact seed annuals. Surfinias are still in first place in the world more than 20 years later. The original trailing types come in 20 different colors and feature novel genetics including Baby Deep Purple, Deep Red, and Yellow. Four Patio varieties and three Baby Compact hues are among the mounding types. The floriferous and thick habit of the new Bouquets has particularly appealed to growers. The new Denim is one of the five new colors available in Surfinia Bouquets. The new Rose, Pink, and White Surfinia Summer Double Petunias are the most exciting 2013 introduction, though. By providing the exceptional heat and weather endurance for which Surfinias are renowned, the Summer Doubles reimagine double petunias.
Cuttings that have been rooted need to be potted as soon as possible into 4- to 6-inch containers. It is advised to use one liner per pot and a well-drained peat/perlite mixture with a pH of 5.5 to 5.8. At this point, crop temperatures should range from 55 to 60 F. Watering is important since overwatering might cause root rot. When plants are very young, a little-and-often regimen is recommended. Surfinias are heavy feeders, so in addition to liquid fertilizer, it is advised to use slow-release fertilizer as they grow.
For Surfinia to become a bushy, spreading plant, pinching will be necessary to promote the proper habit and breaks. After potting, this should be done two weeks later. Daminozide (B9), which can be sprayed at a rate of 2,500–5,000 ppm, has an effect on Surfinia. At 1-3 ppm, a Bonzi drench can be used. Use as necessary. High heat and high light conditions promote the rapid growth of surfinia.
- four-inch pots from one liner with one pinch, four to six weeks 6-inch potsone liner and two pinches after seven to eight weeks 10″-wide baskets With three liners and two to three pinches, for 10 to 12 weeks.
Aphids, fungus gnats, mites, beach flies, thrips, and whiteflies are important pests to keep an eye out for. Botrytis, Phytophthora, Pythium, Powdery Mildew, and Rhizoctonia are among the diseases that need to be avoided.
Twenty years ago, Surfinia was well on its way to becoming a household name among European consumers who enjoyed gardening because of how well its hanging baskets sold for the money. Whereas earlier no other plant could withstand the harsh circumstances of summer heat and severe rain, it replaced ivy geraniums on balconies in Austria, Switzerland, and Germany. It simply looked amazing as it performed continuously while hanging down in window boxes and baskets. The English summers’ coolness did not phase Surfinia at all. Along with resistance to mildew, the plant’s capacity to blossom again up the stems was a remarkable strength. By the end of August, the majority of petunias grown from seed would have lost their bloom. Additionally, customers are not required to deadhead the blooms. Surfinia cleans itself.
Surfinia is a propagator’s dream, taking 3–4 weeks at most to root on a bench. Plant growth regulators (PGRs), especially B9, have an effect on it. It quickly turns into a 4-inch pot on the bench thanks to its branching nature. It is simple to flower in the container and maintain compact growth with PGRs or a dry regimen. Keep plants cool, pinch the crop just once, and plant it in a plug or a 4-inch pot. Feed it well for the duration of its life. Make sure there is enough fertilizer in the finished pots. Always supplement liquid feed with a slow-release substance, such as Osmocote. They are simply insatiable! Plant liners in odd numbers, such as three or five, in larger containers and baskets. Mix with a mound of Temari verbenas, Desana ipomoeas, or Million Bells calibrachoas for arrangements.
