Perennials that require no fertilizer: Included are ornamental grasses, false indigo, ground covers, butterfly weed, bee balm, coneflowers, black-eyed Susans, sea holly, dianthus, asters and veronica. summer: Use a quick release food in summer, instead of a slow release food.
Standard Miracle-Gro “all purpose plant food” fertilizers are synthetic and should not be used in organic gardens.

Broadcasting a slow release fertilizer is the best choice to meet season-long plant nutrient requirements, but you can also use a balanced fertilizer such as 20-5-10. If your soil test indicates that you do not need phosphorous, choose a product such as 20-0-10.
Perennial plants may grow quicker with excessive nitrogen (the first number on a package of fertilizer), however this might increase foliage growth and decrease bloom production, or lead to the onset of damaging or deadly diseases. So it's best to use fast-acting fertilizers with a high-nitrogen content.
Cut back the tops of the plant until you can see the growing sections of its “crown”, the area where roots and tops come together at the soil surface. Be sure to leave enough tops to use as handles for lifting the plant. Dig the entire plant up and set it onto a tarp or cart as mentioned above.

Perennials: Rake away mulch in spring and apply 1-inch of compost around plants. Lightly fertilize plants if needed with a complete granular fertilizer. This can be repeated mid-summer if growth is weak or foliage is light green in color. In late summer, fertilize plants that will bloom late summer through early fall.
Like all plants, perennials need nutrients to thrive. Perennial beds tend to be crowded and competitive, meaning the plants are fighting over limited soil nutrients and can benefit from an infusion of fertilizer.
Spring Perennial Plantings:
Week 1: Every day to every other day. Weeks 2-3: Water 2-3 times per week, depending on environmental conditions. Weeks 4+: Water 2-3 times per week, more in hot/dry conditions. When cooler, water less.
Most perennials grow best in soil that is well drained with good fertility and a pH of 6.0 to 7.0. Adding organic matter to soil improves the fertility, texture, and water-holding capacity. Apply a two to three inch layer of mulch to conserve water, reduce the need to weed, and keep soil temperature cool.
Fertilizing in the fall helps plants be hardier when the temperatures drop. We also recommend applying fertilizer in the late fall, toward the end of October or early November. This application will catalyze one last frenzy of root growth and really give your plants some staying power through the cold months.
However, complete fertilizers sold for flowering plants (including roses and bulbs) such as 15-30-50 or 10-30-20 contain higher amounts of phosphorus (the second number) than nitrogen or potassium and are often labeled as “blossom or bloom booster”.
It does not need much fertilizer; however, if your soil is not in good shape or the plant is not thriving you may need to feed the plant. Rich soil and a lot of water is just as important for hosta health as is fertilizer. New hostas planted in the spring will need a good starter fertilizer to help establish the roots.
MG is so strong that if used incorrectly, the fertilizer will actually burn the leaves and roots of your plants (you may have already experienced this). Imagine what it's doing to the healthy bacteria, fungi and other soil microbes that are working so hard to provide the nutrients your plants need.
