I will add my favorite foliar feed routine. I take a handfull of alfalfa meal and soak it in water for 24-48 hours, then strain and dilute in one gallon of water. I add a tsp or so of liquid silica, and spray at lights out. I can almost guarantee new growth in two days.
Alfalfa meal costs me $12 for 50lb. As always organic is better but either way it is good stuff. I also use it in my compost, as a soil amendment, and in teas. Here is a blurb on alfalfa meal.....
Alfalfa provides many nutritional benefits not only for plant use, but for soil organisms as well. One very important ingredient is tricontanol, a powerful plant growth regulator.
Orchid and rose growers make an alfalfa tea and spray it directly on as a foliar fertilizer. Alfalfa is very high in vitamins, plus N-P-K-Ca, Mg, and other valuable minerals. It also includes sugars, starches, proteins, fiber and 16 amino acids. Approximate analysis is 3-1-2.
Sprinkle lightly over garden and water, or use about a handful (depending on the size) around each rose, tree, or shrub. Alfalfa meal and hay used for mulch contain vitamin A, folic acid, trace minerals and the growth hormone “tricontanol.” Use at 25 pounds per 1,000 square feet or 400-800 pounds per acre.
Alfalfa helps plants create larger flowers and increases the tolerance to cold. Make alfalfa tea by soaking 1 cup of alfalfa meal per 5 gallon of water.
Good for all flowering plants. Research has shown that using more is not better. At recommended rates alfalfa worked wonders on roses but it could be overused causing adverse effects.
