8. Ferns
Whether you are growing classic Boston ferns in hanging baskets or striking Japanese painted ferns in a shaded corner of your patio, these ancient plants are entirely dependent on moisture to thrive.
Ferns do not have deep taproots; instead, they rely on a dense mat of fine, hair-like roots that sit very close to the soil surface. They also absorb a significant amount of moisture directly from the air.
A summer thunderstorm creates the perfect microclimate for ferns, soaking their shallow roots while simultaneously pushing the relative humidity of the air close to one hundred percent.
This prompts the ferns to unfurl new fronds—tightly coiled structures known as fiddleheads—at an accelerated rate. After a storm, you will notice your ferns look significantly fuller and greener. Ensure your hanging baskets have drainage holes so the ferns do not sit in standing water, which can quickly lead to root rot despite their love for moisture.
