World Record Breaking Fertilizer
Get outstanding results from your plants with this amazing concentrate from France. In less than ten years, Algoflash has won 27 Guinness World Records for the production of large plants: the 13 ft. geranium at right (grown in one season), a Dwarf Chrysanthemum with 7,794 blooms, a Philodendron 45 ft. in circumference and so on.
Algoflash was originally created for French vine growers in the Loire Valley. It is now the number one selling liquid fertilizer in France. It differs from other leading fertilizers sold in the United States in that it is a liquid 100% completely soluble in water, a 100% mineral base combined with a range of pure trace elements and magnesium. It is non-toxic, made from all natural mineral ingredients, odorless and environmentally friendly-and very economical to use. One liter of concentrate will make 450 liters of fertilizer for use (about 115 gallons). Algoflash supplies a full range of nutrients, quickly available to boost growth, flowers and fruit.

Spring Rose Wake Up
After a very hot and dry summer our roses were very weary going into the fall/winter season. Had lost most of their leaves and we were concerned if they would survive. When I saw new leaves starting I gave them a drink of Algo Rose, and they look wonderful. They all have tiny flower buds and the leaves look healthy! So happy with Algo!

Awesome product!!
I've been using Algo plus on my roses for the last 12 years and it is absolutely, by far, the very best rose fertilizer available! Everyone around town has everbloom roses and theirs are all less than 3 ft tall min get up to 6+ ft with huge amounts of blooms in a single season.

This is the best fertilizer that I have ever used. My roses had a beautiful display after using this. My roses were 17 years old and Marilyn Monroe rose was beautiful. Some that I thought was dead came back also. I use almost all of the alto fertilizers. I have already got my items for this spring and summer.Will stay a repeatr customer !! Thank you !!!

Best Rose Fertilizer!!
I've been growing roses for 45 years, and this is the best rose fertilizer I've found to date. The roses are much larger, fuller, more vivid, and more abundant. The foliage is also more abundant, with richer color. More importantly, especially in Florida,the foliage becomes far more resistant to blackspot and mildew because of its vigor.

You won't believe how many blooms. Easy application. About 40% or more blooms of better qaulity and larger size. Fantastic for bush types.
