Q.Rhubarb
What should I fertilize my rhubarb with.?
The year after planting, it's a good idea to fertilize your rhubarb plants in early spring, before the plant begins to sprout significantly. Use an all purpose fertilizer - a 10-10-10 formula works well. Compost or well rotted manure also works well as a fertilizer. If you use a granular type fertilizer, apply it according to the manufacturer's instructions. It is usually applied at a rate of 1 1/2 pounds per 100 square feet. Sprinkle the granules around the plant, being careful not to let the granules come in contact with the plant itself. This may burn the plant or have other adverse consequences. After applying the granular fertilizer, water it in well
