Poinsettia Care

The poinsettia, the most popular holiday plant, is best known as the plant with bright red flowers on a green background.

Storing Apples for the Winter

Though this year’s peach crop may have been a disappointment, most gardeners are finding apples in abundance! Most trees are bearing above-average loads, and many home-growers will be searching for new recipe ideas to use up the heavy yields. Why not store some of your crop for fresh eating throughout the winter?

Still Time To Plant Spring Flowering Bulbs This Fall

There’s still time to get those spring-flowering bulbs in the ground yet this fall. Though generally it is recommended to get the bulbs planted by early October to give them enough time to root before winter, it is better to plant now rather than try to store the bulbs over winter.
