Have you ever planted seeds and forgotten to label them? Every gardener has made this mistake at least once!
When it comes to squash plants, it can actually become a huge headache not knowing what type it is! Some winter squash varieties can turn into huge sprawling vines, so you want to make sure you place them where they can grow!
Did you know that you can identify squash plants using their leaves? The leaves can give some clues as to what type of squash they are, based on size, shape, color, and texture.
Keep reading to discover how to identify squash plants using their leaves with our simple squash plant leaf identification guide!
How to Identify Squash Plants By Leaves
It matters which type of squash plant you have so that you can care for it correctly.
Tips for Identifying Squash Plants by Leaves
Examining a squash plant’s leaves can be an excellent way to identify which type of squash you have. Leaf identification a lone is not always perfect – for example, it can be challenging to identify young squash seedlings by leaves. You can also identify squash plants with:
- Plant size
- Bush or vine growth
- Flowers
- Stems
- Fruit
If you are determining a squash plant by its leaves make sure you are paying close attention to the leaves’
- Color
- Texture
- Shape
- Size
If you’re not sure, refer to the pictures in this guide to help identify the squash plants by their leaves.
Examining your squash plant’s leaves will also help identify and prevent diseases such as bacterial wilt and powdery mildew.
Squash Plant Characteristics: Leaves
With several shapes and sizes, squash plants display characteristic leaves.
Leaves help create energy from the sun for the plants to grow, called photosynthesis. Without photosynthesis, squash plants cannot grow!
The majority of squash plants’ leaves have big veins running from the base to the edge.
Squash leaves develop in an alternate arrangement along the stem. This means leaves grow out of the stem from different locations and not opposite each.
There are many combinations of shapes, textures, and appearances of leaves, which will make the identification of squash plants difficult. Fortunately for you, here is the squash leaf identification guide!
Identification of Squash Plants
Squash plants are known for their large leaves, and squash can be a standout in the garden!
There are two major types of squashes:
- Winter Squash includes delicious varieties, butternut, acorn, and spaghetti
- Summer Squash includes scrumptious varieties,s zucchini, pattypan, and crookneck
Need to identify winter squash varieties or summer squash varieties by leaves? By looking at the differing characteristics of the leaves, we can identify squash plants.
- Colors
- Texture
- Serrated leaves
- Smooth leaves
- Lobed leaves
There is certainly plenty of variability within categories. However, by looking at the differing characteristics you can learn to identify squash plants by leaves.
Let’s get to it!
Identification of Squash Leaf Color!
Squash leaves are generally a bright green leaf. However, shades will vary greatly depending on the variety (some can be light green, mottled, or some can even be purplish green!) Also, be aware that the color of a squash leaf may not indicate the variety.
Sometimes if there is something bad happening with a squash plant its leaves become pale, or outright yellow. There’s always a good chance that too much sun or not enough sun could affect the color of leaves.
But don’t worry, there are more characteristics to help you identify a squash plant by its leaves.
Identification of Squash Leaf Texture!
You may have possibly seen some of these words used to describe the texture of different squash leaves:
- Smooth
- Velvety
- Crinkly
- Rough
- Sandpaper
- Fuzzy
- Prickly
The texture of a leaf is also a considerable clue in identifying the squash plant.
Smooth leaves are readily seen with butternut, acorn, and some Pepo varieties.
Rough textures can frequently occur with spaghetti squash, zucchini, and even other summer squashes.
Identification of Squash Plant by Serrated Leaves
Serrated means notched like the teeth on a saw.
Look closely at the edges of the leaves. Do you see little notches? It could help identify varieties such as zucchini as well as acorn.
Identification of Squash Plant by Smooth Leaves
Not all squash plants have spiny or fuzzy leaves. Some will have smooth, waxy, or even velvety leaves.
Examine your plant’s leaves; if they are smooth, it could indicate that it is a butternut or buttercup squash variety.
Identification of Squash Plant by Lobed Leaves
Lobed leaves are common to many types of squash varieties. There can be anywhere from three to seven deep lobes. Some plants will have shallow lobes that are less pronounced.
Many summer squashes have deeply lobed leaves. To show you, our old pal zucchini has lobed leaves, and they are serrated.
Acorn squash has lobed leaves, too, but the lobes are uniquely shaped, resembling an oak leaf.

Diseases
Unfortunate as they are, squash plants can be prone to some diseases. Determine and react quickly, and you could still have a relatively okay squash crop.
Here are some tips for identifying and treating two common diseases that affect squash plants.
Identify Squash Powdery Mildew by the Leaves
You may have noticed squash plant leaves with little white spots and started wondering what they were. They may be powdery mildew.
Sometimes, powdery mildew can start as little bumps, eventually, white powdery mold growth can take over the leaf. The white can also be a gray color.
Powdery mildew usually develops in late summer and may develop into the fall.
White spots appear on both sides of the leaves, and also often on the stems.
If left untreated, powdery mildew:
- It will affect the health of your squash plants
- Limits growth
- Limit crop production
How To Treat White Powdery Mildew?
- Spacing: Make sure you give your squash plants plenty of room to grow. If they are crowded together, the airflow is limited, and disease can establish itself. Squash plants like room to breathe!
- Be Fast! Powdery mildew develops quickly, so try to act on it as quickly as you see the problem.
- Remove Affected Leaves: If white powdery spots are only on a few leaves, remove them. Throw the infected leaves away; do not put them in your compost pile, as this will only spread powdery mildew
- Topical Treatments: Try spraying organic plant sprays for powdery mildew issues. Some can be used to help combat other pests like mites
- Neem Oil: Neem oil is an oil from the neem tree. Neem oil is a very effective plant treatment for powdery mildew. You can either buy neem oil or an easy, ready-made spray to apply to your squash plants
- Vinegar spray: This is a simple and inexpensive way to use something you have in your cupboard! Mix 4 tablespoons of vinegar in 1 gallon of water. Use a spray bottle to apply it to your squash plants every 3 days
Identify Squash Bacterial Wilt by the Leaves
Have your squash plant leaves ever suddenly wilted? If so, you may have bacterial wilt.
This disease presents itself in the following stages:
- Green leaves suddenly droop
- Wilted leaves turn yellow
- Leaves become brown and die
How To Treat Bacterial Wilt?
Bacterial wilt cannot be treated, but you can either manage or prevent the development some bacterial wilt disease.
- Pest Control: Cucumber beetles are a known pest that creates bacterial wilt; keeping cucumber beetles away will limit infections. Use an organic plant spray.
- Remove Affected Plants: Once you determine you have bacterial wilt, make sure you analyze and remove any affected squash plants. You should garbage can your infected plant matter, and not put it in your compost pile when you have bacterial wilting as an issue!
