Alfalfa contains triconatol, which promotes plant growth. Alfalfa also conditions the soil. Promotes enzyme activity in the soil, and vigorous growth. Can also green up leaves. Feeds the soil by adding organic matter and basic nutrients, which in turn improves the soil and feeds soil life.
Healthy soil makes for healthy plants.
One fertilizer that we absolutely do not recommend is liquid chemical fertilizers like Miracle Grow. Do not use this on Rugosa roses. If you do, you stand a very good chance of burning up the plant. Rugosas are the toughest roses we grow, but they just can't handle the high nitrogen and chemicals salts in Miracle Grow type fertilizers. If you don't believe us, just go ahead and apply it to the leaves or around the base of a Rugosa plant.
