Before the Autumn leaf colours start to invade our senses I am just recapping on the leaves that have made an impact for me this summer.

Leaf miners are the larvae of moths, beetles, maggots, flies or caterpillars that have hatched between the upper and lower epidermis of a leaf. They then burrow there way out eating part of the leaf and leaving a trail.

Here are the Most Beautiful Types of Big Leaf Caladium Varieties that will surely turn a lot of heads with their big, bold, and fantastic foliage!

Airborne fungal spores land on buds to infest newly-emerging leaves in spring. The fungus feeds on the young leaves and affects their development so that they become distorted. The smaller leaf size makes them less efficient at making food for the plant and in its weakened state, the flowers and fruit fall off. Trees may recover sufficiently to make a second flush of growth and these leaves are usually unaffected by the fungus. Fungus survives on fallen leaves and branches to re-infect next season’s buds.

Have you noticed the persistent brown leaves still hanging on some deciduous trees long after their foliar companions have fallen? This usually becomes very apparent after normal leaf drop in early winter. These brown leaves may remain attached until spring bud growth pushes them free.

Perennial vines in the genus Vinca have proved to be sturdy and seemingly indestructible groundcovers for the Southeastern Unites States. However, over the past few years, vinca leaf-folder caterpillars have been ravaging landscape plantings of perennial vincas (Vinca major andVinca minor). Both can be infested, but V. major seems to sustain more damage. According to Dr. Matt Bertone, Entomologist at NC State University, this pest is likely Diaphania costata.

Soon, ghosts and goblins will take to the streets to celebrate this season for the macabre. Today, Halloween is an occasion for dressing up in costumes and trick-or-treating. Its origins include pagan and Christian observances commemorating seasonal harvests and the memories of loved ones who have passed away.

Leaf color change is one of the most iconic events that define the fall season. In a matter of days, the green color gives way to bright yellow, orange, and red hues. The appearance of these colors not only increases the beauty of our forests but also helps the growth of our orchards and backyard trees. These fall colors are created by pigments such as ß-carotene, anthocyanin, or lutein. Some may wonder, “why would trees spend energy in creating these pigments right when they are about to drop their leaves?” The answer is that the strategy is not about spending but saving for the next season.

This leaf is showing symptoms of a fungal disease called large leaf spot (Monochaetia sp.) that affects oaks and chestnuts. The appropriately named spots may reach 2 inches wide and stretch across the entire leaf, killing large amounts of tissue.

This Napa cabbage is being fed on by larvae of both the yellow margined leaf beetle (YMLB, Microtheca ochroloma) and vegetable weevil (Listroderes difficilis). YMLB can be a significant pest for organic production, especially turnips and Napa cabbage, which they prefer.

Cut leaf evening primrose (Oenothera laciniata) is a native, biannual plant. It forms a rosette during its first year of growth and produces yellow flowers on low spreading stems in its second year. The pretty, yellow flowers open in the evening and close during bright, sunny conditions Flowering will last for over a month, and sphinx moths and native bees pollinate the flowers. Unfortunately, the plant also hosts the tarnished plant bug, a piercing, sucking insect that feeds on vegetable and ornamental herbaceous plants.
