Yes, there are many fertilizers that are safe for our babies. They are all organic and cannot be found at any of the chain stores. Generally, they are found at small independent organic nurseries. Sometimes they are granular, sometimes they may be a spray on topical. If you google "organic gardening" you'll find lots of information.
Natural organic fertilizers are much much better for your yard than chemical fertilizers. In fact the chemical fertilizers, e.g., Scott's, are extremely harmful and toxic to humans and animals. The nitrates get in our ground water and it is very bad.
Also, did you know that the weed and feed products can actually kill your trees and landscape shrubs, etc. Yes, it is true. In addition to being very harmful to ground water, humans, and animals, it can actually kill trees and shrubs.
Seaweed is very good as a topical spray. Compost tea is a wonderful fertilizer. There are also treatments that introduce micro-organisms into the soil which loosen the soil and make it more amenable to taking in rain and water.
Top dressing with compost is a great thing to do. Also, aerating your yard will help tremendously with how it grows and looks.
Another thing that is as good as any fertilizer is using a mulching mower. If your mower shoots (mulches) the grass clippings down into the lawn, that is a great fertilizer.
The city where I live, Austin, Texas, encourages its citizens to go organic and they ask us to NOT use the chemical fertilizers. You can find lots of helpful information at the Austin city website.
