Secrets Of Producting Sun Parasol Mandevillas

Sun Parasol Mandevillas

Sun Parasol is the brand for a completely new collection of mandevilla hybrids, an entirely new group of varieties obtained by cross-breeding. The genus mandevilla has many subgroups, including sanderi, boliviensis and amoena, which are all known for their climbing or trailing properties. Until recently, sanderi was the leading variety in North America. However, the market for mandevilla has changed dramatically with the arrival of Sun Parasol. The popular Crimson varieties are the first that stay true to color. The new ‘Sun Parasol Garden Crimson’ is capturing a lot of attention as the first bedding plant mandevilla.

Sun Parasol mandevillas are classified into four groups:

• The Originals come in Crimson, Pink, Cream Pink, Dark Red and White with bushy, compact growth and medium-sized flowers. Exciting novelties – Stars & Stripes, Lush Crimson and Burgundy – are available in limited supply. Plants have good branching, neat foliage and are natural climbers suitable for pots, hanging baskets, balconies or as bedding plants and house plants.

• The Giants are available in White, Pink, Crimson and Carmine King. They have a vigorous growing habit, coarse foliage and are natural climbers suitable for patios, balconies and as house plants in sunny areas. They are the classic mandevilla.

• The Pretty group, which comes in Pink and Crimson, is distinguished by superior branching and vigorous growth. It can be grown as a traditional pot plant, even in 4- and 6-inch pots. Flower size is the same as the Original group but foliage is glossy, thinner and more vining. Plants are natural climbers suitable for hanging baskets, patios and balconies.

• The Garden group begins with Garden Crimson. These plants are uniquely positioned for quart pots and will finish in 14 weeks. Plant in masses in beds, containers and baskets. No trellises are needed for support.

General Culture

Mandevillas are long-day plants. Buds are initiated with 10-11 hour days for the Pretty type and the Originals. The Giant group will flower with 12-hour days. Varieties in each group vary depending on the color. Ideal growing temperature is 65-75ËšF the first two to three weeks after potting. Keep plants on the dry side to encourage roots to grow out of the plug quickly. Temperature can then be lowered to 65-70ËšF. Lower temperatures can be used, but plants will take longer.

Initial potting should take place in a 4-to 5-inch pot. Growing media should have a pH between 5.0 and 5.5. Depending on the time of year, three to four weeks after potting, the leading shoot will begin to grow quickly. The plant will then require a pinch to encourage a bushy habit. Two types of pinches can be carried out:

Method 1 – This type of pinch is a soft pinch, where you will leave at least four pairs of leaves and get fewer breaks and take these up for training. Pinching is done higher.

Method 2 – This method is for short, compact plants. Regular pinching is required once the desired height has been achieved. This will encourage a bushy and dense plant for a nice finish and earlier sale.

Watering

Watering is critical and a dry regime is more suited than a wet one, where plants can become prone to root diseases. Too dry and there will be a problem with nutrient uptake. It is best to water lightly and often. The best way to control growth is with water retention, especially with the white-colored varieties.

Pests & Diseases

Monitor for whiteflies, western flower thrips, aphids, red spider mites, fungus gnats, shore flies and mealy bugs. Diseases to prevent are Botrytis, Phytophthora, Rhizoctonia, Fusarium, Cylindrocarpen (root rot),  Cercospora (leaf spot) and Colletrotichum (leaf spot).

  1. I brought a sun parasol mandevilla in the house last fall. Eventually it quit blooming but is still living. Will it bloom again this summer. Is it possible to start new plants from one. Thank you

  2. My Star & Strip Sun Parasol mandevillas seems like it has many buds but do not fully open. I just had one solid red one open and others that are striped look small and have not fully opened. I have not fertilized it yet I gave it B1 in March 2015. I live in San Jose CA. I’m very concerned as to why the many buds do not appear to open and looks like it dries up. I have this plant growing on a trellis.

Hospitals Are Getting Into The Organic Food Business

Growers investing in the organic food movement could serve a growing new area with vegetable transplants and starts, as well as produce, as hospitals begin to prescribe healthy diets and nutrition, and even go so far as to grow their own food. As part of a new phenomenon among progressive hospitals, health professionals are beginning to realize that without health and nutrition, programs and techniques may be done in vain or worse — obsolete. As more patients seeking a healthy diet turn to nutritionists, who recommend sugar-free, alkaline diets to prevent disease and aid in recovery, hospitals recognizing this trend are taking action. St. Luke’s Hospital in Bethlehem, Pa., recently contracted with the nearby Rodale Institute to manage an organic farm, established in 2014. The hospital, part of a six-campus network, aims to provide excellent healthcare, part of which includes educating patients about the benefits of a plant-based, organic diet. […]

Syngenta Plans To Divest Flowers Business

Changes on the breeder front continue as Syngenta announces it intends to divest the Flowers seed business from its Lawn and Garden operating unit. According to an August 19 press release, “divestment would enable the new entity to play a leading role in the consolidation of the home gardening market, which is taking place in response to changes in the distribution and retail channels, driven by shifts in consumer preference.” The high-quality and profitable Flowers business will be sold in its entirety, including Syngenta’s seed and vegetative flower genetics, as well as its facilities in Gilroy, Calif., and offshore, says Paul Minehart, Syngenta’s head of corporate communications for North America. Differences in the corporation’s offerings and little overlap with the agricultural seeds and crop protection side of the business are the primary reasons behind the sale, Minehart says. “Flowers is a premium, consumer-focused business,” he says. “Syngenta is a market leader […]

Customizing Crop Foliage Color With LEDs: Ornamental Cr…

Do you find that your purple fountain grass (Pennisetum setaceum ‘Rubrum’) crop is often green to light purple? What if we told you there is a quick solution to enhance and darken the foliage of purple fountain grass or other floriculture crops? In this second article of a four-part series highlighting the multiple uses of high-intensity light-emitting diodes (LEDs), we will discuss our research methodology and findings for enhancing the foliage color of ornamental crops with end-of-production (EOP) supplemental lighting (SL) in the greenhouse. Many ornamental crops that greenhouse and nursery growers produce vary in size, shape and color. These variables are often influenced by the growing environment. For example, leaf color (intensity, distribution or both) of ornamental crops such as purple fountain grass is a key component that often influences the consumer’s perception and ultimately an impulse purchase. The red or purple pigmentation of purple fountain grass leaves is […]

Soil System Improves Growing And Sales

My father started our company 45 years ago growing bedding plants, mainly early season production and finished plants for our West Virginia market. It was in the early 1980s that we started growing earlier spring production and shipping materials to southern markets, and by the late 1980s, we also produced pansies for fall. We started using hydrogels when they first came on the market in the early 1990s and found that they really helped with our production by keeping plants healthier for these new markets. Over the years, we’ve grown to be a large young plant producer and have a sizable business growing finished plants in cell packs, 4 1/2-inch pots, 6-inch pots, gallon containers, hanging baskets, multiple sizes of large containers and large baskets for municipal use. Creating The Ideal Soil Mix With our old system, it took several workers to mix pre-made soil with slow-release fertilizers in cement […]
