SAN DIEGO ROSE SOCIETY FERTILIZER SALE

Rosarians around the world know roses are heavy feeders and benefit from a regular food and water diet throughout the growing year. Our society is committed to helping us provide this optimum diet for our roses. Our fertilizer sale will continue for the 13th year. Here’s our chance to plan ahead to provide our roses with the BEST and LEAST EXPENSIVE nutrients for optimum growth. We don't have to stockpile a lot of product now or pay for the fertilizer way in advance. We lovingly give our roses their spring feeding on FEBRUARY 14 (because we love our roses so much !!) 

In times of drought it is important that we feed our roses well & regularly. When roses are fed well they develop strong roots extending deep into the soil, and can withstand drought much easier.  

BioStart 3-4-3 Organic Fertilizer from Growmore is manufactured fresh each year with bone meal, potassium sulfate, humic acid, beneficial bacteria, ecto and endo mycorrhizae.  BioStart can be applied at a rate of 2 cups per large bush and 1 cup per small rose bush in the spring. One 50 pound bag contains about 100 cups and will feed about 50 large roses once or 25 roses two times.  BioStart may be reapplied in the late summer for a renewed fall bloom.  WE ARE THE ONLY RETAIL SOURCE IN THE U.S. FOR THIS AMAZING PRODUCT. 

Magnum Rose 8-10-8 Water Soluble Fertilizer is formulated for roses, contains all needed micronutrients and can be applied 1 tablespoon to a gallon of water. One gallon per large rose, ½ gallon per small bush applied every 2 weeks from March 1st to October 15 (that is 18 feedings).  One pound = about 32 tablespoons.  One 25 pound bag will feed about 25 roses. 

Better Than Fish can be added, 1 tablespoon, to the same gallon of water. One gallon contains about 250 tablespoons, which will feed about 16 roses if applied as above through the growing season.  

Seaweed Extract Liquified Organic Kelp provides improved root development, more vigorous growth, increased resistance to diseases & insects and can be added, 1 tablespoon to the above gallon of water. Foliar feeding with Seaweed can really benefit your roses, you may consider applying by a hose-end sprayer several times a year.

Jump Start Plant Tonic brings new life into older plants and gives new plants an extra boost by providing vitamins and minerals needed to encourage new growth and stress resistance, accelerating leaf, stem and root growth. Both Superthrive and Jump Start contain Triacontanol, the “magic hormone”. Jump Start beats Superthrive in performance and price. Apply 1 teaspoon per gallon of water. 

ADDITIONAL FERTILIZER 

Think about trying some of these products which can be used by adding them to your existing program of applying Magnum and/or Fish, & Seaweed by the gallon to your roses. This would include  Biocozyme and Humic Acid. If you currently use/buy any iron product for your roses (I do)  Eddha 6% is a good price and can be added to the above several times a year for increasing the deep green leaves.  Dexter, from GrowMore  talked a lot about the benefits of foliar feeding with Seaweed. Dexter adds the other water solubles to that sprayer to fertilize his garden. Bob Martin had been adding SeaGrow  16 -16- 16 to his feeding program for several years and sweared by the combination of  SeaGrow and Seaweed & Magnum Grow.  BTW, all these products (and the others we order) retail for lots more than we pay. We try to keep the price low & pass the savings along.

HUMIC ACID 8% Organic (liquid)  Application - 1 tsp/gallon every several weeks, for really bad soil - 1 Tbsp/gallon.   Humic acid retains nutrients and benefits plant growth. This is particularly good for potted roses because of the nutrient holding qualities of humus. 

HUMIC ACID (Granular)   Application - 1/2-2/3 c. applied with BioStart in the spring.
Gardeners know that humus is wonderful for its effect in helping roses and other plants to grow. How can we help produce more humus in our soil and why is it so beneficial? Humus is a complex substance that results from the action of bacteria and fungi on organic matter. It is recognized as the dark brown to black material in the surface layers of the soil. The particles of humas are microscopic. Amending the soil by thoroughly mixing organic material such as planting mix or compost before planting is the initial way to build humus. In order to continue renewing the soil with humus, add 3-5 inches of organic much each year after pruning your roses. Organic fertilizer also makes a contribution. Many of the properties of humus are due to its negative charge. Think of it like a magnet. The multiple small humus particles with a negative charge hold on to nutrients, most of which have a positive charge. These include nitrogen in the form of ammonium, potassium and iron. Water also has a positive charge and is retained by humus. Humus also has a sponge-like quality that holds water for roots. Roses like a slightly acidic soil with a pH between 6.2 and 6.8. A pH of 7.0 is neutral with levels above this being alkaline and levels below being acidic. Humus plays a major role in stabilizing the pH so it does not become to alkaline or acidic. Humus decays very slowly, at an average rate of 3% per year. It is the largest source of nitrogen reserves in the soil. It consists of about 5% nitrogen and 0.5% sulfur. Humic acid is just one of the many components of humus and consists of organic materials. Most of the time the humic acid is derived from leonardite which is also known as brown coal. Leonardite is a mined product. This, like coal, is the result of prehistoric organic material subjected to prolonged decomposition.

EDDHA IRON CHELATE 6% Powder-1 lb Application -1 tsp/gal    

Fully chelated DTPA iron chelate helps prevent iron chlorosis by maintaining and protecting iron availability in slightly acidic to slightly alkaline soils with a pH of up to 7.5. It prevents iron from binding with other compounds in the soil, allowing it to stay in a form readily available for plant use.
