Orange Beetles Are Killing My Flowers, or Are They?

Many gardens are being invaded by orange beetles that have a strong preference for flowering plants. Rest assured, these are soldier beetles and they aren’t feeding on the flowers! Instead, they are actually predators and pollinators.

Saving Seed: Will the seed produce plants similar to the plant it was collected from?

It can be very rewarding to harvest and save seed of ornamental and vegetable plants. But why is it that sometimes when we plant the seed we saved, the results do not seem to be very like the plant we collected the seed from?

Black Vine Weevils Becoming Active

Black vine weevils are now showing up across the state. It is typical for the adult beetles to emerge in early summer and begin feeding on plant foliage. They primarily feed on lilacs and yews, both common landscape shrubs. Although the adults cause minimal damage, their larvae feed on the roots and can occasionally be a threat to ornamental plants, especially those grown in pots or containers.
