June brings the end of school, Father's Day and summer. Summer brings hot weather and plants may need extra water. Honey bees will also need extra water to keep the hive cool.

Houndstongue is a beautiful plant in the spring. It boasts many tiny, nodding, burgundy-colored flowers. However, in the fall, this plant becomes a terrible weed to avoid at all costs. The beautiful little flowers spend their summer creating little tick-sized and shaped seeds that will stick to anything and everything that brushes by them! These plants can become invasive and can cause real problems for livestock and other animals.
