Spring is a great time to plant or transplant trees and shrubs.
If you have perennials that need divided, as soon as you begin to see new growth emerge, split the perennial clumps and transplant them.
For gardening success, do a soil test. We have a number of products to choose from:
The Pennsylvania University - Soil Test Information Kit, done by mail
Rapitest pH Soil Test
Rapitest Soil Test Kit which contains four tests: pH, Nitrogen, Phosphorus and Potash
When choosing a fertilizer, the three numbers, such as 20-10-20, refer to the percentage of Nitrogen, available Phosphate and soluble Potash that it contains.
The Soil Test Kit will tell you the content of the nutrients in your soil, so you will know how to amend the soil to get it to the appropriate levels. Or the pH level will determine what types of plants will grow well in that soil, as plants have alkalinity preferences.
Read more about pH in our How-to guides for trees and shrubs, How Do I Change the Color of My Hydrangea Flowers?
For blue Hydrangeas blossoms, add Aluminum Sulfate to the soil to lower the pH of the soil.
Apply Bulb-tone to your established Spring and Summer plantings when they reach 6 inches in height. Fall plantings can be fed after they bloom in the Spring.
Before the weeds begin to take over your mulch beds, you can spray any visible weeds with a weed killer, such as Roundup, and then put a new covering of mulch down. Then, you can apply Preen Garden Weed Preventer on top of the mulch to prevent the growth of new weeds.
While the plants are still dormant, apply All Seasons Horticultural & Dormant Spray Oil to plants that are susceptible to scale or mites. It will kill all stages of insects including eggs. This must be done before the buds show green tissue.
Prune any spring flowering shrubs, like Forsythia, right after they have bloomed.
