Aphids on Roses

Many gardeners use the systemic rose food. This product is a combination of fertilizer and an insecticide. The product needs to be applied on the soil around the base of the plant and lightly worked in. As the roses are watered, the fertilizer and insecticide are absorbed by the roots.

Bee Swarm

Bee swarms occur in almost every beehive once a year, usually in the spring. In managed, commercial hives the beekeeper can manipulate and divide the hive to prevent swarming. In every hive there is a time in late winter/early spring when the hive begins to produce new queens.
