In 2011 Everris™ introduced Osmocote Bloom to the market. Osmocote Bloom is a specially designed controlled release fertilizer for bedding plants like petunias, begonias and geraniums. It helps improve the quality of the plant by delivering maximum nutrition throughout the crop cycle, selling and early consumer stages. Osmocote Bloom can also save you money on labor costs.

Product Characteristics:• Specially developed for bedding plants• Complete trace element package• Longevity of 2 – 3 months• Recommended rate is 2 – 4 gram per liter of

pot volume• Using a starter fertilizer is not necessary, nor

recommended• Mid-size granule is perfect for mixing into

smaller pots and packs

Directions for useOsmocote Bloom has been developed for incorpo-rating into the growing media. Osmocote Bloom begins its nutrient release immediately after application, so the product should be mixed-in right before potting the plants.

During the first period after mixing, EC levels will be low. Depending on the soil temperature, nutrients are gradually released throughout a 2 – 3 month period. In the majority of bedding plant cultures, this longevity matches the entire cultivation period and even the first weeks of the consumer stage. The recommended dosage is 2 – 4 grams per liter of pot volume. However, this depends on the crop and the growing situation (see page 7 for recommended crop rates).

For more specific advice, please contact your Everris advisor or potting soil manufacturer.

Your benefits from using Osmocote Bloom• Specifically designed for bedding

plants.• Healthy, compact and uniform plants.• Sustainable; less emission to surface

and ground water.• Compliant with (MPS) regulations for

nitrogen and phosphate emission.• Save on labor costs; one application is

all you need.• Easy application; designed for mixing

into growing media.• Lower EC value in the potting soil,

better growth.• Less fertilizer inputs and better results• Improved shelf-life for consumer phase.

Keeping watering and nutrition phases seperateThere are three possible fertilizer application methods when cultivating bedding plants: using a water soluble fertilizer, a coated fertilizer or a com-bination of the two. Controlled release fertilizer Osmocote Bloom enables the grower to keep the watering and nutrition phase separate, therefore less fertilizer inputs are necessary. Labor costs can also be decreased as one application is sufficient for a complete fertilizer program for bedding plants.

Sustainable nutritionAs with all Osmocote products, Osmocote Bloom is a sustainable fertilizer. A considerable amount of fertilizer can be saved per hectare. This fertilizer should be applied directly into the growing media, near the plant’s roots.

Improved shelf lifeWith Osmocote Bloom, plants are fed from the initial potting stage and continue all the way up to the first consumer phase; increasing customer satisfaction. Nutrition is released throughout the fertilizer’s longevity, assuring healthier plants in garden centers and less-wasted plants. The plants will remain healthy and vibrant for a longer period of time and therefore customers are more apt to continue to buy the same plants.

The perfect analysis for bedding plantsOsmocote Bloom has a NPK analysis which is ideal for bedding plants which have a 2 – 3 month crop cycle. It has a full trace element package and the small granules are perfect for maximum distribution throughout the growing media. The NPK ratio is also specially designed for condensed growth.

Product description

Product information• Packaging details: 25 kg bag• Product code: 8739.02.01XF• Coating process: 100% coated NPK + trace elements

Directions for useAs a result of the unique resin coating technology of Everris, Osmocote Bloom, for bedding plants, has a very regular release pattern. It is especially suitable for use in short-term bedding plant cultures (from 6 weeks up to 3 months). For other bedding plant types we recommend using Osmocote Exact Standard High K 3 – 4M or 5 – 6M. The longevity of Osmocote Bloom is affected by temperature (product longevity is tested and determined at 21º C).

Store Osmocote Bloom in a dry place. Partly used or damaged bags should be properly closed.

Product information

Osmocote Bloom is a controlled release fertilizer specifically designed for bedding plants in small pots. It contains NPK, magnesium and all other necessary trace elements for a healthy growth. The granule is 100% coated and has 2 – 3 months longevity. In some situations (e.g. when crop cycles are longer than 2 – 3 months, or when using plant hole dibbling equipment), Everris recommends using Osmocote Exact which will deliver the best safety and maximum performance.

ApplicationThe recommended rates mentioned above are based on non-fertilized substrates. Maximum results can be reached when the potting soil does not contain a starter fertilizer. However, if a starter fertilizer has been used, we recommend using no more than 0.5 g/l in combination with the mentioned application rates. Osmocote Bloom is primarily meant for mixing in the growing media – we do not recommend this product when dibbling. Re-fertilization with water soluble fertilizers and/or adjustments for water quality can be required under certain circumstances. Contact your Everris advisor for more specific advice.

Trial first on a small scale before rate, full application or other changes in your cultural practices are implemented. As circumstances can differ, and as the application of our products is beyond our control, Everris cannot be held responsible for any negative results.

Trial results in France

To test the effect of Osmocote Bloom on the quality of bedding plants and leaching of nutrients, research was executed at the official trial station RATHO in Brindas, France.

The trial was executed in 11 bedding plant varieties under standard growing conditions. Osmocote Bloom was compared to other organic and water soluble fertilizers. Organic fertilizers were included in this trial to test their performance and effect on the environment. The use of a base feed in combination with an application of water soluble fertilizer later on in the cultivation period is seen as a common practice and was therefore also tested.

Leaching of nitrogenOsmocote Bloom and the organic fertilizer clearly showed lower nitrogen le-aching than starter fertilizer + water soluble fertilizers: the nitrogen leaching was up to 12 times lower per week! Nitrogen leaching with organics also gave a positive result, but the plants did not reach the required quality.

Leaching of phosphatesOsmocote Bloom also minimized the leaching of phosphates compared to organics and starter fertilizer + water soluble fertilizers. It is remarkable that organic fertilizers gave a negative result with the phosphate leaching. Osmocote Bloom delivered extremely uniform bedding plants in all varieties tested, whereas the organic fertilizer caused salt damage and discoloration to the leaves.

Activity

Week 13 Start of trial and potting of bedding plants at 153 plants per m2, first measurement of irrigation water supplied, drainage percentage, taking drain samples

Week 17 Replacement of plants from 110 to 153 plants per m2

Week 20 Finalization of the trial, assessment of plant quality

Cultivation of the crops

Leaching of the fertilizer was tested by collecting all drainage water from each treatment while analyzing its contents on a regular basis. The total water quantity was also measured per crop, so that results could be translated to practical circumstances at grower level.

Due to the controlled release of nutrients, it is possible to grow plants more gradually, without growth peaks caused by the availability of high quantities of fertilizer. Although plants were treated with growth inhibitors in the same way, it is possible to use lower rates of chemicals under certain conditions.

Key conclusions • Plants fertilized with Osmocote Bloom show better root

development in comparison with plants treated with water soluble fertilizer.

• In Begonia and Calibrachoa results show that with Osmocote Bloom there are more compact plants of a higher quality.

• Quicker blossoming and maturity plants with Osmocote Bloom.

• Plants fertilized with Osmocote Bloom were ready for sale 2 – 4 days earlier.

In 2011 Everris conducted a trial to test the effect of Osmocote Bloom with a starter fertilizer in short cultures. The purpose of the trial was to find out if adding a small amount of starter fertilizer can enhance leaf color and branching. A single application of Osmocote Bloom appears to not be sufficient enough for short cultures (3 – 4 weeks). The build-up of nutrition appeared to be too low. The trials were conducted at Pot and Bedding Plant Nursery Peter van der Plas in Maasdijk, the Netherlands.Treatments were applied to Viola, under normal growing conditions. Osmocote Bloom without starter fertilizer was compared to a treatment of Osmocote Bloom with starter fertilizer.

Better growth with Osmocote Bloom and starter fertilizer for short cultures

The best results were recorded in the treatments with 3 g/l Osmocote Bloom + 0.5 g/l starter fertilizer. Plants were well branched, showed good color and were nicely compact. Adding a small amount of starter fertilizer delivers the best results for short cultures like Viola cornuta. Key conclusion

• Adding 0.5 g/l starter fertilizer to an

application of Osmocote Bloom gives the best results in short cultures of 3 – 4 weeks (and late summer cultures like autumn pansies).
