Knowing how to make organic plant food saves you money as well as being better for your plants and the rest of the environment. Since it has none of the harsh chemicals in purchased fertilizers, it won't be as likely to burn your plants. It is a good idea to take your soil to your county extension agent for testing so that you can create the correct plant food for your specific needs, however.
Organic Plant Food Recipes
There are many different kinds of homemade plant food and fertilizer recipes. Most of them are simple and easily made with ingredients you may already have on hand. Always keep your homemade products in a well marked, glass container out of children's reach. Even though they are organic, they may still be harmful if a child ingests them.
Manure tea is a simple, liquid plant food that is good for all kinds of plants. Use it as a quick start fertilizer for seedlings that have recently been transplanted or as a boost for those that aren't doing well.
Always compost the manure before using it in the tea. Once it is composted, it is safe to use on vegetables as well as flowering plants and shrubs.
- Fill a container 1/3 full of well rotted manure.
- Fill the remaining space with water and put on a lid. Make sure the lid isn't too tight.
- Allow to sit for two weeks during which time it will ferment. This results in the manure tea concentrate.
- After two weeks use one part manure tea concentrate with ten parts of water. It will be the color of weak tea.
- Apply to plants as needed.
Seaweed tea is made exactly the same as manure tea; you just need to make sure to rinse the salt off the seaweed before you use it. If you live by the beach this is one of the best fertilizers that you can put on your plants. Seaweed is higher in the nutrients that plants need than any other material.
Compost Tea is yet another variation, made in the same way as manure tea. Use a rich, organic compost and follow the directions carefully.

Keeping It Organic
Although some things, like Epsom salts, don't come in organic versions they are all natural and can be used in organic gardens.
