Why trim your zucchini plants in Denver?
One of the primary reasons for trimming the leaves below the fruit is that the plant only uses the leaves above the fruit to collect sunlight.
By removing these lower leaves, you can increase airflow around the plant, which helps reduce the risk of powdery mildew and other diseases later in the season.

Steps to Properly Trim Your Zucchini Plant
1. Identify the Main Stem
The first step is to locate the main stem of your zucchini plant. In our example, we're using a patty pan zucchini. You should be able to see the fruit growing on the main stem.
2. Locate the First Fruit
Once you have identified the main stem, find the fruit that is lowest on the plant. This fruit will act as your guide for where to begin trimming.
3. Trim Away Lower Leaves
Trim away all of the leaves that are below the first fruit. This can be done as close to the main branch as possible, but be careful not to cut into the main stem itself. Properly trimming your plant this way ensures that you do not harm the plant while maximizing airflow and light penetration.
Bonus Tips for a healthy zucchini plant
Always use clean, sharp pruning tools to make clean cuts and reduce the risk of disease.
Compost the trimmed leaves to recycle nutrients back into your garden.
