We firmly believe that an unforced plant is better prepared for the transition from nursery to garden. Conifer needles and peat make excellent additives to increase acidity. Depending on your climate many ferns will tolerate morning and late afternoon sun, but most need protection from intense mid-day sunshine. Ferns are not particularly bothered by pests. Ferns are not tolerant of many pesticides and should be protected from general spraying.
Oil based sprays are particularly hard on foliage.
Newly planted ferns should be watered regularly and deeply until they are well established. We prefer not to water when the sun is on the foliage. As ferns mature they become more drought tolerant. They also should be winter hardy if you match appropriate plants for your USDA zone.
