Common Mistakes Growing Parsley in Rhode Island

One common mistake in Rhode Island is planting parsley too early in the season, particularly in cooler regions where frost may linger. Wait until after the last frost date to ensure your young plants thrive.
Many gardeners in Rhode Island underestimate the impact of humidity on parsley. Excess humidity can lead to fungal issues; therefore, proper spacing and airflow around your plants are important.
