All newly planted trees and shrubs require special watering attention. Be sure to read our watering instructions thoroughly and call any of our Plant Clinics if you have any questions.
Container plants are grown in a potting mix of pine bark, compost and sand intended to provide excellent drainage. With these plants, be sure to loosen up the roots prior to planting and check them for watering more frequently than B&B plants. Sometimes even though the surrounding soil is moist, the potting mix is dry.
B&B plants are in denser, heavier soil than container plants, so it is best to water them very slowly, allowing the water to seep deeply into the root ball. Gator Bags, drip irrigation and soaker hoses are especially effective for this use. Once thoroughly saturated, B&B plants may not need to be watered as frequently as container grown plants.
Watch out for tent caterpillars in cherries, crabapples and plums. When the caterpillars are small (less than 1″ long), you can spray with an organic product, such as Thuricide or Monterey’s Garden Insect Spray. These products are only toxic to caterpillars. If you wait until the caterpillars are longer than 1″ you will need to spray with Sevin.
Boxwood leaf miner and boxwood psyllid can be controlled in late April or early May by treating with Bonide Systemic Insect Spray.
Creeping phlox, bleeding heart, candytuft, pansies, snapdragons and sweet alyssum are just a few of the early spring bloomers that thrive in the warm days and chilly nights of early April.
Annuals add instant color to your landscape beds and pots, creating a sense of welcome just in time for spring. If you are planting annuals, such as geraniums, marigolds, New Guinea impatiens or any other tender plants, keep a close watch on the weather forecast and be prepared to protect them with frost cloth when frost is predicted (do not cover them with plastic).
We recommend fertilizing your annuals and perennials with Merrifield Flowering Plant Food. This product contains slow-release nitrogen, sulfate of potash, iron and other micro-nutrients for overall plant growth and development.
