If you want to meet season-long plant requirements, broadcasting a slow release fertilizer is the best option. Pick a product that contains phosphorous if your soil test shows that you don’t need it.

Should I fertilize my flower beds in the fall?
You should start feeding flowers in the spring and stop in the late summer. Don’t fertilize them during the fall or winter. Make sure the soil is moist before applying any type of fertilization. Fertilize your plants in spring and fall, but do not apply fertilizer in winter. If you do, the plants will not be able to take up the fertilizer and will die.
When should you stop fertilizing plants?
July 1 is the last day to applyfertilizer. Before winter, new growth needs time to “harden off”. Tender new growth is at risk of cold injury if it is forced late in the season, when plants and trees should be at their best. Fertilize in late May or early June. This is the time of year when trees and shrubs are most vulnerable to frost damage.
If you fertilize too early, you may not have enough time for the plants to fully develop their leaves and flowers before frost sets in. You may also not be able to get enough nitrogen into the soil to support the growth of the tree or shrub you are fertilizing. In this case, it may be best to wait until the next growing season.
Should you feed perennials?
Then, any time between late April and mid May, perennials need a dose of feed. Blood, fish and bone can be used as general-purpose fertiliser. It should be spread on the soil around the plants. If you want to keep your plants healthy, you’ll need to give them plenty of water.
You can do this by sprinkling them with water at least once a day, or by watering them every other day. If you don’t have a drip irrigation system, use a garden hose to water them.
What perennials should not be cut back in the fall?
As soon as possible, dispose of them in the spring. In the fall, when the weather is cooler and the soil is dryer, it is a good idea to prune the plants back to their original size. This is especially true if you have a large number of plants in a small space. Pruning can be done by hand or with a pair of pruning shears.
If you are using a hand pruner, be sure to use a sharp blade that is not sharpened on one side. A dull blade can damage the roots and cause the plant to wilt. It is also important to keep in mind that a pruned plant will not produce as many flowers as a plant that has not been trimmed.
What happens if you don’t cut back perennials?
Diseases can overwinter in dead foliage, as can slugs and other pests. The crown and roots of the plant can be damaged by the fall and winter winds. Cut back any plants that are not healthy.
When should perennials be cut back?
In late fall, once all of your perennials have started to turn brown and die back, it’s time to prune some and leave the rest for the next year.
