About Netted Chain Fern
Lorinseria areolata · also called Netted Chain Fern, Net-veined Chain Fern · flowering
The netted chain fern, Lorinseria areolata, is a deciduous North American wetland fern that spreads by creeping rhizomes to form colonies in acidic, boggy ground. Its sterile fronds resemble a small sensitive fern, with a distinctive net-veined pattern, while the slender fertile fronds stand erect. Ideal for pond margins and rain gardens in shade.
Preferred mix: Wet, acidic, humus-rich soil
Watch for — Drying out: As a wetland fern it browns and dies back fast if the soil dries. Maintain wet to saturated conditions at all times.
Why netted chain fern needs this mix
Netted Chain Fern hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Netted Chain Fern comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons netted chain fern struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for netted chain fern — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets netted chain fern dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for netted chain fern?
Netted Chain Fern prefers a slightly acidic mix (around pH 5.5-6.5); a peat-free compost-and-coir blend sits there naturally, so routine pH testing is unnecessary.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A good peat-free houseplant compost works for netted chain fern straight from the bag if you mix in some perlite for air. The DIY ratio above gives a more reliable moisture-to-air balance.
Drainage and the pot
Use a pot with a drainage hole but a less-porous material (plastic or glazed) so it does not dry too fast. Bottom-watering keeps the mix evenly moist without sogging the crown.
Peat-free mixes slump and compact as they hold moisture, so refresh netted chain fern's mix every 12-18 months to keep air in the rootball even if the pot size is unchanged. When the time comes, our repotting guide for netted chain fern covers the timing and technique step by step.
