If you’ve ever watched your zucchini plants start strong and then suddenly collapse
mid-season—leaves covered in white fuzz or fruit rotting before it grows—you’re 
not alone. The biggest mistake most home gardeners make with zucchini is simple:
they plant too close together.

That’s it. Not spacing them properly.

Zucchini needs room. And not just for the leaves to sprawl—though they will—but 
for air to move and pollinators to do their job. When plants are packed too tightly,
two major problems creep in:

### 1. **Powdery Mildew**

You’ll recognize it as that white, dusty coating on leaves. It starts small and 
spreads fast. The cause? Poor air circulation. When zucchini leaves don’t have space
to dry out after morning dew or rain, mildew thrives. It doesn’t kill your plants
right away, but it weakens them, slows growth, and cuts your harvest short.

**Fix it:** Give each plant at least 3 feet of breathing room. Yes, really—3 feet.
That might mean fewer plants in your garden, but trust me, healthy plants produce
more than crowded, stressed ones.

### 2. **Poor Pollination**

Zucchini plants have separate male and female flowers. Bees need to move pollen 
from one to the other. But if your garden is a leafy jungle, pollinators can’t get
in easily—or they skip your zucchini altogether. That’s when you get misshapen or
shriveled fruit.

**Fix it:** More space means bees can find the flowers. Also, don’t be afraid to
hand-pollinate. Just take a male flower, peel back the petals, and dab the pollen
onto the center of the female flower (the one with a little baby zucchini behind
it).

**Bonus Tips:**

 * **Water at the base** of the plant in the morning. Wet leaves = fungus magnet.
 * **Mulch around the roots** to hold moisture and reduce weeds.
 * **Cut off diseased leaves** as soon as you spot them—don’t wait.

Zucchini is a generous plant when it’s happy. Get the spacing right, keep the air
flowing, and help the bees out. You’ll be swimming in zucchini by midsummer—without
the frustration.

Your plants will be healthier. Your harvests will be bigger. And best of all, you’ll
avoid the #1 mistake most growers make.
