Why ferns and trailing plants love a window

There is something quietly perfect about a fern suspended in a cottage window. The Victorians were mad for them — the fern craze of the nineteenth century filled glass cases and conservatories the length of the country — and the appeal has not faded. A window gives you exactly what most houseplants are desperate for: soft, bright daylight without the scorching midday sun, plus the humidity that gathers around kitchen sinks and bathroom sills.

Trailing plants make the most of the space. Rather than crowding your windowsill with pots competing for the same square foot, you lift them into the light and let them cascade. A spider plant, a string of hearts, a golden pothos, a maidenhair fern in a terracotta pot — hung at slightly different heights, they soften a plain sash window the way a lace curtain does, and they look charming from both inside and out.

A macramé hanger is the simplest way to get there. You need no specialist tools, no sewing machine, and about an hour of an evening. Below is a hanger built from eight cords and a wooden hoop: sturdy enough for a decent-sized pot, gentle on the plant, and pleasingly rustic in the way good cottage craft always is.

What you will need

• Recycled cotton cord, 3–4mm thick — eight lengths of 3 metres each. Cotton is kind to fingertips and holds a knot well; synthetic cord slips.
• A wooden hoop or ring, 8–12cm across — a plain birch or beech ring is ideal, and a hoop is easier to hang from a ceiling hook than a solid ring.
• Sharp scissors — blunt ones fray the cord ends and make everything messier.
• A plant pot no wider than 15cm, with a saucer or a plastic liner inside the hanger.
• A ceiling or window-reveal hook, plus a wall plug or a screw eye long enough to bite into timber.
• Optional: a little moss or coir around the pot's base to hide the plastic rim and hold moisture.

The three knots that do all the work

You do not need a knotting manual. Three knots carry the whole project.

• Lark's head — fold a cord in half, pass the loop through the hoop and pull the two loose ends through the loop. This attaches each cord to the ring.
• Square knot — take two cords, cross the left over the right, tuck under and pull; then cross right over left, tuck under and pull. Two moves, one secure knot.
• Gathering or wrapping knot — a short length wound tightly around a bundle of cords and knotted to close the basket at the base.

Knotting your hanger, step by step

• Cut eight cords of 3 metres. They will look far too long — they are meant to. Knotting eats length quickly.
• Attach all eight to the hoop using a lark's head knot, spacing them evenly so the hoop is balanced. You now have sixteen loose strands.
• Number the strands one to sixteen, left to right. Starting about 12cm below the hoop, tie a square knot using strands 1 and 2, then 3 and 4, and so on to 15 and 16. You will have eight knots in a ring.
• About 8cm further down, tie a second row, but this time take one strand from each neighbouring pair: knot 2 with 3, 4 with 5, 6 with 7, and so on, finishing with 16 with 1. This staggered row is what makes the net open into a basket shape.
• Work a third row 8cm below the second, matching the pattern of the first row.
• Slip your potted plant into the net and check the fit. Adjust the spacing between rows now, while it is easy.
• Gather all sixteen strands together below the pot and tie a tight gathering knot with an offcut of cord. Leave the remaining tails to hang as a tassel, trimming them level about 10cm down.
• Hang the hoop on its hook and even out the cords so the pot sits level.

Hanging it safely in a British window

Weight is the thing to respect. A 15cm pot filled with damp compost can weigh two to three kilograms, and a soaked fern more. The cord will happily take it; the fixing is the weak link. Screw into a joist or a solid lintel where you can, or use a proper masonry plug in a brick reveal — never rely on plasterboard alone.

Think about placement, too. Keep hangers clear of radiators, which will dry out fronds faster than anything, and away from doorways where a swinging pot will meet shoulders. If your window gets fierce afternoon sun, a few centimetres of shift can be the difference between lush and frazzled.

Styling, watering and keeping it lovely

Cottage style rewards a slightly relaxed approach. Hang three at staggered heights in a tall sash window, pairing upright ferns at the back with trailing ivy or a chain of hearts in front. Terracotta pots suit the look better than glazed ones, and the natural cream of cotton cord sits warmly against old painted woodwork.

Water by taking the whole hanger down and setting the pot in the sink. Let it drain thoroughly, then rehang — this keeps drips off sills and wallpaper, and spares you the misery of a watermarked windowsill. Ferns appreciate a misting every few days in centrally heated rooms, and a weekly turn keeps growth even on all sides.

Finally, give the cord an occasional brush with a soft cloth and check the knots each season. Cotton softens and stretches slightly with age, so a quick tighten here and there will keep your hanger hanging beautifully for years.
