A Mercury retrograde spell works best when it is small, practical and set before the retrograde begins, and Mercury turns retrograde at 20 degrees Scorpio on 24 October 2026. This post gives you a three-knot cord working you can do in about ten minutes, the folk history behind it, and a plan for undoing it when Mercury turns direct on 14 November (AEDT).
The dates, and what is astronomy versus astrology
Mercury is the planet closest to the Sun, and it races around its orbit faster than Earth does. Every so often it lines up between us and the Sun and appears to drift backwards against the background stars for roughly three weeks. That drift is an apparent motion, a trick of perspective, and it happens three or four times a year. That part is astronomy.
The meaning is astrology. Mercury is the traditional ruler of speech, writing, travel, contracts and short journeys, so practitioners treat a retrograde as a time when messages go astray and old business resurfaces. According to Cafe Astrology’s event page, the pre-retrograde shadow begins on 4 October at 5 degrees Scorpio, the station retrograde falls on 24 October at 20 degrees Scorpio, Mercury turns direct at 5 degrees Scorpio on 13 November US Eastern time (the early hours of 14 November in AEDT), and the post-retrograde shadow runs to 30 November. For the full breakdown, see our Mercury retrograde in Scorpio guide.
Why knots, and why a cord
Knot magic is one of the oldest and most documented forms of folk practice, and it suits Mercury well because a knot is a decision made physical. It holds something in place until you choose to release it. The Museum of Witchcraft and Magic records a 14th-century account of witches “putting the wind under three knots of thread”, with sailors loosening the knots one at a time when they wanted wind. Its page on selling the wind also covers the Isle of Man practice called raising the wind, and its collection includes a white rope with three knots linked to the tradition on the Devon and Cornwall coast. The museum notes that the older origin claims for that particular rope are not verified, so treat the details as folklore rather than settled history.
The mechanism borrowed here is simple. You tie something loose and unruly into a cord, you carry it as a reminder, and you untie it on a date you chose in advance. The knots give your attention somewhere to rest, and the untying gives the retrograde a clear ending. Cord is a patient ally for this. It is made to bind and hold, and it will keep a promise for as long as you ask it to.
What you need
You need one length of natural cord about 60 centimetres long (undyed cotton, hemp or jute twine works well), a pen, a small slip of paper, and a safe place to work. A light blue or grey cord suits Mercury if you have one, but any colour will do. A candle is optional. If you use one, a tealight in a proper holder on a heatproof surface is plenty, and you can skip it entirely.
Choose your three knots first
Before you touch the cord, write three short lines on the paper. Each one names a specific communication risk you want to manage over the retrograde, such as “I will reread every important email before sending”, “I will confirm bookings in writing”, and “I will back up my files on Sunday nights”. Keep them behavioural. A spell that says “nothing will go wrong” has nothing to work with, while a spell that says “I will check twice” gives you something to do every day. Mercury retrograde tends to expose what was already loose, so the best knots tie down real loose ends, such as an unanswered message, an unsigned form or a plan nobody has confirmed.
The working
Do this on 24 October if you can, or any day from now until then, ideally in the evening and somewhere you will not be interrupted. Clear a small space, put your phone on silent and lay the cord and paper in front of you. Take three slow breaths and read your first line aloud, plainly, as if you were telling a friend. Hold the cord in both hands, tie a single firm overhand knot near one end, and say “Held until Mercury is direct” as you pull it snug. Pause, read the second line aloud, tie the second knot in the middle of the cord with the same words, then read the third line and tie the last knot near the other end. Notice that each knot should be firm but easy to undo later, so avoid pulling them so tight that you would need to cut them. Hold the finished cord for a moment and say aloud the date you will untie it, 14 November, then fold the paper and keep it under the cord or inside your diary. Thank the cord for its work. Carry it in a bag or pocket, or hang it by your desk where you will see it each day, and when you catch yourself rushing a message or a decision, touch the cord and check the item twice before you go on.
Unknotting on 14 November
Mercury turns direct on 14 November in AEDT, the same day Venus turns direct, so it is a tidy moment to close the working. Our guide to the Mercury and Venus double station covers what that day is about. Untie the knots one at a time, in the order you tied them, and read each line aloud again. Ask yourself honestly whether that item was handled, still needs attention, or is no longer relevant, and write the answer in your grimoire or diary. Many practitioners keep the shadow period in mind, so you might leave the paper in place until 30 November before retiring the cord. When you are done, the cord can be coiled and stored for next time, since it keeps no residue and can be reused.
Safety
Never wear the cord around your neck or wrist where it could catch on machinery, a bag strap or a door, and keep it away from young children and pets who might chew or swallow it. Keep any candle in a stable holder on a heatproof surface, away from the cord, paper and curtains, never leave it unattended, and snuff it out when you finish. If you decide to burn the paper at the end, do so only in a fireproof dish with water nearby, or tear it up and recycle it instead. This working is a focus and habit tool, so it does not replace backing up files, confirming appointments or reading contracts. It also makes no health or legal claims, and anything important, such as a legal, medical or financial matter, deserves proper professional attention.
Making it fit the southern hemisphere
This retrograde falls in late spring in Australia, with the year ending, school and work deadlines stacking up, and Halloween and Beltane arriving on 31 October. That is a busy stretch for messages and bookings, which makes the three knots especially practical. If you want a seasonal touch, tie the cord outdoors in the evening light, or hang it near an open window where spring air moves through. The point is the same wherever you are, which is to decide in advance what you will pay attention to, and to give that decision a form you can hold.
