– Fall is Coming!!

Fall will be here soon, and I want to share some observations and ideas that will be helpful and not too hard to implement.

• FALL FOR CHRYSANTHEMUMS:

Mums begin to set buds and come into flower naturally during the Fall. They come in several colors. Purchase them as early as possible so they may develop strong rooting systems and rebloom next year. Mulch around them to protect the plant from heaving, freezing in Winter.

• DID YOU KNOW - ABOUT BULBS?

Planting daffodil bulbs in the Fall will insure you will have a beautiful Spring of surprises.

There are bulbs that come out all throughout the Spring. Some in solid colors, others with varied vibrant color. Look through the catalogs and order several different varieties to keep the show preforming all Spring long.

Deer do not eat daffodils for they are poison to them and these bulbs multiply year after year. Buy them by the bag.

Another favorite bulb is Japanese Iris. They multiply and persist for years, especially if the soil is improved. Plant them along a path you frequent to appreciate their delightful fragrance.

• SAVING SEEDS:

What to do with all the zinnia, marigolds, daisy, coneflower heads after they bloom and look dead?
1. Cut them off and save in paper bags or baskets open to air.
2. In the Spring, brake apart the seed heads and sprinkle into the prepared beds of soil.
3. Cover with an inch of soil and water.

• PRUNING IN THE SPRING OR FALL:

1. I prefer to prune in the early Spring for often times cutting stimulates new growth which is tender and can freeze in the cold Winter.
2. Light pruning and removal of dead or diseased branches can be done anytime.
3. Roses should be pruned in April.

Matrix Landscape Design

Master Gardener Educational Credit Opportunities.

Presented by: “Wild Ones”, https://wildones.org/. Wild Ones promote native plants and landscapes, providing education, advocacy and collaborative action.

Matrix planting is a landscape design approach that recommends:
• Utilizing native plants that go well together.
• Planting plants close together and layered.

The aim is to cover the garden soil throughout the growing season, reducing the need for wood mulch and excessive weeding.

This presentation qualifies for Master Gardener Continuing Education credit for time spent.

– Bagworms and other tree caterpillars

Bagworms, Thyridopteryx ephemeraeformis, attack ornamental trees and shrubs in the Eastern United States. Conifers, in particular arborvitae, cedar, juniper, and pine are the most frequently damaged host plants.

Deciduous trees such as sycamore, maple, locust, boxelder, and linden can be attacked, but not seriously damaged.

How to get rid of them?
• Pick the hanging bags off by hand during Winter or early Spring.
• Or spray the tree with natural controls like Bacillus thuringienis better known as BT from May to mid-June when the tiny larvae are actively feeding.
• If absolutely necessary, you can also use a chemical control register with the U.S. Environmental Protection Agency (EPA).

Note, if chemical control is absolutely necessary, always:
1. Make sure it is registered with the EPA.
2. Check the label on the pesticide to be sure bagworm and the type of plant you wish to spray are listed.
3. CAREFULLY FOLLOW ALL LABEL DIRECTIONS WHEN MIXING AND APPLYING THE SPRAY.

Bagworms can often be confused with other tree caterpillars, including:
• Eastern tent caterpillars (Malacosoma americanum), see https://extension.umd.edu/resource/eastern-tent-caterpillars-and-forest-tent-caterpillars-trees/
• Fall webworm (Hyphantria cunea), see: https://extension.umd.edu/resource/fall-webworm-trees/
