No matter what you're considering planting in your garden, it's important to make sure that you've got adequate sustenance arranged for your new plants. Prepackaged plant food can be unnecessarily expensive, especially when you consider the fact that you can easily replicate the same nutrient mix yourself for a fraction of the cost.
Determine whether you need to use agricultural lime or gypsum in your mix. To do this, check to see whether the rainfall in your area is more or less than 20 inches per year. If it's more than 20 inches per year, use agricultural lime. If it's less than 20 inches per year, use gypsum. Do not use both when making your mix; only use one or the other.
Slide your gloves onto your hands, if you're wearing them. If you're mixing your plant food with your hands, you will likely want to wear these gloves.
Mix lime or gypsum with magnesium sulfate and boron in your wheelbarrow. Be careful not to spill any of your mixture before you're ready to use it. Make sure to mix thoroughly.
Apply food in a ratio of approximately 1 oz. per square foot. Work thoroughly into soil about a week before planting.
Store any food you don't use in your empty paint bucket with lid for later use. Make sure the lid fits tightly, so that moisture does not get into your plant food and cause it to clump and become unusable.
