Colorful flowers will attract butterflies in spring, fall

When making a spot that attracts butterflies, choose a warm location out of the wind. Choose flowers in yellow, orange, red and pinks that bloom in spring or fall when it is cooler, and plant them in large numbers.

Good time to look for borers is after rainfall

Right after a rain is a good time to look for borers feeding in the moist cambium of fruit trees. It’s a good time to get out a sharp knife, sanitize and sharpen it, and remove these borers before they cause more damage.

Plants placed in 2 categories: Mesic and xeric
