Watermelons are one of summer’s sweetest rewards, but growing them often requires more space than most gardens allow.
With their sprawling vines and heavy fruits, they can quickly take over your beds, leaving little room for anything else. That’s where a trellis comes in.
Using a trellis for watermelons is a smart way to guide the vines upward, saving ground space while keeping the fruits off the soil.
Not only does this prevent rotting and pest damage, but it also promotes healthier growth and larger harvests. Here’re 15 watermelon trellis ideas to inspire your garden.
