Once you’ve picked the last of your fruits this season, you may think your work with your fruit plants is over. However, a few tasks can be done in the fall to set yourself up for a successful growing season next year.

This year has been good for many plants, but not all. In late spring Central Illinois went through almost three weeks where it rained at least once per day. Many of our plants responded to this favorably. Standing in a pollinator garden a few days ago, the goldenrod towered over me. Our vegetable gardens have seldom needed a drink from the hose. Even the grass has remained mostly green and actively growing.

From evergreens and Poinsettias to holiday cacti and holly, we use a variety of different plants to adorn our homes and offices during the holidays. One plant we commonly hear about is mistletoe. Mistletoe has an interesting past, from an ancient symbol of fertility to somewhere to sneak a quick kiss. It also has a darker side as a freeloading parasite on trees.

Mythology and folklore

It is believed that the golden bough that allowed the Greek hero Aeneas to travel to the underworld was mistletoe.

I bet you’re sick of reading about elections and politics. Fortunately, the Good Growing column is a welcome escape. Today I would like to dive into diseases. Oh, that’s right. We’re kind of in the middle of a global pandemic and I bet “disease” is not on the top of your list either.

Within our global pandemic of COVID-19, I hear scientists and doctors talk about recommendations for preventing the spread of disease. After listening to all the human health experts talk, one thing I realized, folks in the plant world have been dealing with “pandemic” type events for a long time. 

I spend a lot of time asking homeowners to show me their tree butts. Buttress to be specific, but industry lingo shortens it to butt and is described as the dramatic widening of the lower trunk. The buttress of a tree is located beginning at the root flare where the base of the trunk flares out into the root system. How high up the buttress goes depends on the species. For oaks, it may only be two or three foot high. Some tropical trees have buttresses that go up twenty feet!

Tree Injury

Cucumbers, melons, squash, and pumpkins are collectively known as cucurbits. Because these crops are related, they are afflicted with many of the same pests and diseases. Here are some of the most commonly encountered pests and diseases in cucurbits.
Insects

Tomatoes are the most commonly grown plant in the home vegetable garden. Tomatoes are relatively easy to grow, and there is a wide variety of different types. If you’re growing tomatoes, you’ll more than likely encounter a few pests and diseases along the way. So, let’s take a moment and talk about some common issues we encounter when growing tomatoes.

Have you ever noticed the leaves of your peach tree becoming curled and puckered and turning reddish or purplish? If you’ve seen this, you’ve likely had peach leaf curl.

Peach leaf curl is a fungal disease caused by Taphrina deformans. It is one of the most commonly encountered diseases of peaches and nectarines, especially in home plantings. While it primarily affects the foliage, it may also infect blossoms, young twigs, and fruit. 

As summer kicks into high gear, we often start to see more pest problems. An important and often overlooked part of pest management is scouting. It can help you figure out what is going on in your garden/landscape and help you determine if you need to take any action to manage any pests that are present (particularly if you are going to be using pesticides).
