If you want to use organic fertilizer, some of your best choices are alfalfa meal, seaweed meal, and soybean meal. Alfalfa meal is a good alternative to blood meal and is a slow-acting fertilizer. It has a lot of carbohydrates as well as proteins and it encourages the action of soil microbes. The carbon to nitrogen ratio that it has is also one of the best and this helps speed its availability to plants through the soil. By doing this it can offer a lot to flowering shrubs and roses as long as it’s used properly and put into planting beds in the proper amounts.

Two other popular choices are soybean meal and seaweed meal. Seaweed has been used as a fertilizer for a long time, but be careful that it’s prepared correctly. If it wasn’t properly washed it can have a lot of sodium in it, and that will hurt your plants rather than help them. Look for one with a low sodium count.

Soybean meal, on the other hand, is very similar to cottonseed meal and is high in nitrogen. It can usually be found at animal supply stores and works very well for plants that are low on nitrogen or that use it up rapidly. No matter how you choose to fertilizer your organic garden, you should know what each kind of fertilizer does, what kinds of plants like and need it, and how much of it they use so you don’t give them too much.
