Liquid fertilizer is important to have for gardeners that need to give their plants an emergency boost of energy and nutrients. Making liquid fertilizer is incredibly simple, but most liquid fertilizers take a while to steep. Here are ways to make different types of liquid fertilizer for your gardening needs.
Use manure from herbivores because that manure will basically be digest plant material which will be perfectly healthy for stewing to create liquid fertilizer. The process here involves filling a bucket with lots of manure and a good amount of water, covering it for about four weeks, stirring it weekly, and then diluting the solution, which will be strong, with some more water. Then you're ready to feed your plants.
Since weeds are common in many gardens and outside homes, these might be easier to get than manure if you aren't living on a farm raising your own animals. Weed tea can be brewed the same way manure is done, by filling part of a bucket with weeds and other broken up or chopped plant parts, as long as those plant parts aren't diseased, then steeping with water for less than a month, stirring several times each week. Mix some of the final solution with some more water before feeding to your plants because your weed tea might be too strong.
Take some compost from your compost pile and blend it basically liquefying it. Add some water and let it steep for some time. Steeping can take a day or so since the solids are already liquefied, but just need to stew properly to be ready for use. Dilute with more water as needed before pouring onto plant soil.
In all cases, the mixtures should be properly covered so bugs and insects don't get into the solution, but should have some form of ventilation so that gas can escape and fresh air can get in and circulate for the steeping process.
