This is a powerful time of year: winter has broken, water is running high, and the energy of action and courage is in the air. The alder is the tree for this moment. The Celtic Month Alder (March 18 to April 14) celebrates rebirth, resurrection, and sunrise as it heralds spring with new leaves.
In Gaelic, the month of Alder is referred to as Fearn (pronounced fa-rin), and it is the fifth month in the Ogham calendar. Alder is linked to both male and female principles and represents balance. Along with balance Alder wood has shielding and protection qualities.
A majestic tree, the powerful alder can be found across the Northern Hemisphere in cooler climates. Alder (Alnus glutinosa) grows along rivers, streams, and wetlands. It loves water and is one of the few trees that actually thrives with its roots submerged. This relationship with water is central to everything the alder represents.
In this article, I will talk about the symbolism of the alder, magic and spells, deities associated with this tree and the importance of the alder tree and its conservation.

Symbolism of the Alder
The alder carries a specific set of symbolic meanings rooted in its physical nature and its role in Celtic mythology.
Protection and Courage: The blood-red wood linked the alder to warriors and battle magic. Shields were sometimes made from alder wood. It's the tree of the fighter who stands their ground.
Boundaries Between Worlds: Alder grows at the edge of water — the boundary between land and the otherworld. In Celtic cosmology, water was a threshold, and the alder stood guard at that threshold. It has strong associations with liminality, the space between.
Steadfastness: Because alder wood hardens and becomes nearly indestructible in water, it symbolizes resilience and the ability to remain strong under pressure, in difficult or emotionally overwhelming situations.
Death and Resurrection: The red wood, combined with the tree's ability to thrive in conditions that would kill other trees, tied the alder to themes of death, transformation, and rebirth. It was a tree that could "bleed" and still live.
The Otherworld and Prophecy: Alder is connected to the fae, the ancestors, and messages from the spirit world. Its position at the water's edge made it a place of communication with what lies beyond the veil.
Fire and Water: The alder bridges two opposing elements. Its wood was used to make charcoal, connecting it to fire, while its roots are in water. This dual nature makes it a tree of balance and transformation between opposing forces.

Deities To Honor For Alder
Several deities have strong connections to the alder and are worth honoring during Fearn month. These aren't the only deities you can work with during this time, but they have direct ties to the tree itself.
Celtic Gods And Goddesses
Bran the Blessed (Celtic — Welsh)
Bran is the deity most directly associated with the alder in Celtic tradition. His name in Welsh means raven, and his mythology is layered with alder symbolism. Bran is a giant king and warrior, a figure of tremendous strength and sacrifice. In the Mabinogion, he gives his life for his people and is connected to themes of protection, the otherworld, and the cauldron of rebirth.
Read my blog Ravens & Crows: Spirit Animals, Messengers, and Guides
Bran is the deity to call on when you need courage to face something difficult, when you are making a sacrifice for others, or when you are doing work with the ancestors. His sacred bird is the raven. Honor him with dark red offerings, whiskey or mead, and iron.
We talked about his father Lir (Llyr), God of the Sea, last month in the Celtic Month of Ash
Male catkins (yellow, dangling) and female catkins (small, red/green) are associated with Bran. They are used in rituals, linked to water, and shifting between realms.
The Morrígan (Celtic — Irish)
The Morrígan is a goddess of battle, sovereignty, fate, and prophecy. She is deeply connected to the themes that run through Fearn month: courage under pressure, the cost of conflict, and what lies beyond death. She appears at boundaries — between life and death, victory and defeat — just as the alder stands at the boundary between land and water.
Call on the Morrígan during this month for protection, for the courage to confront what you've been avoiding, and for clarity when facing hard choices. She doesn't soften things, but she gives you the truth and the strength to act on it. Offerings include red wine, crow or raven feathers, and weapons or iron.
Arawn (Celtic — Welsh)
Arawn is the king of Annwn, the Welsh Otherworld. He rules the realm of the dead and is associated with hunting, magic, and the cycle of life and death. The alder's connection to the otherworld and its blood-red transformation makes it a fitting tree for Arawn's season.
Work with Arawn during Fearn month for ancestral communication, shadow work, or magic involving transformation. He's also a deity of fairness and keeping one's word - this is a good time for oaths and commitments. Honor him with black offerings, bones, hunting imagery, and time in nature.
I would love for you to watch one of my videos - please and thank you! I am working on getting enough watching hours to get the YouTube channel monetized. With the additional income I plan to pay our writers (yes, they are humans) to produce more content for you including articles, free downloads, books and videos for YouTube. (Ame~ founder CPH)
The horned one is associated with nature, fertility, animals, and the underworld. Modern pagans and nature lovers like myself continue to honor him. Learn all about him and ways you can develop a relationship with him.
Cernunnos (Celtic — Continental/Gaulish)
Cernunnos, the antlered god, is a deity of wild nature, animals, liminality, and abundance. As the land wakes up in late March and April, Cernunnos's energy is very present. He is a bridge between the wild world and the human world, and between the living and the dead — another liminal figure suited to this month.
Honor Cernunnos during Fearn month by spending time in nature, particularly near water or in wild spaces. Offerings include antlers, coins, animal imagery, grain, and fruit. He's a good deity to call on for abundance work and for connecting with the wild, instinctual self.
People Born in the Month of Alder
People with the alder as their birth tree are charismatic and driven. However, they can sometimes be immature and impatient too. Alders are natural leaders renowned for their confidence and focus on tasks, carrying the alder's best attributes.
Alders generally get along well with everyone and are typically extroverts, although exceptions certainly exist. They hate wasting time and love it when their plans come together and they get their communities involved.
For these reasons, Alders get along fantastically with persons born in the months of Hawthorns, Oaks, as well as some Birches.

Alder Magic
The energy of Fearn month is well-suited to specific kinds of magical work. Here are spells and practices to consider during this period.
Protection Magic
The alder's warrior nature makes this an excellent time for protection work. A simple but effective practice: carve a protective sigil or rune into a piece of alder wood (if you can source it) or onto red paper. Hold it while visualizing a strong boundary around yourself, your home, or whoever needs protection. Speak your intention aloud. Keep it on your altar or in a protective bundle.
If you have access to an alder tree, you can gather a fallen branch. Use it to create a protective wand or boundary marker for your space.

Courage Working
If you are facing something that requires courage — a difficult conversation, a major decision, a confrontation you've been putting off — this is the month to work with it.
Spell: Light a red candle. Place a piece of bloodstone or red jasper in front of it. Write down what you need to face on a piece of paper. Speak it out loud: what it is, why you've been avoiding it, and what you need in order to move forward. Call on Bran or the Morrígan to lend you strength. Burn the paper (safely) or bury it in the ground. Carry the stone with you as a reminder of the commitment you've made.
Ancestral Communication
The alder's position at the boundary between land and water makes this a good month for reaching out to ancestors and working with the spirit world. Set up an ancestral altar near water if possible — even a bowl of water on your altar works. Offer food, drink, and a candle. Speak to your ancestors directly. Ask for their guidance or simply share what is happening in your life.
Scrying in water is particularly well-suited to Fearn month. Use a dark bowl filled with water and work by candlelight. Allow your eyes to soften and your mind to quiet, and see what comes.
Decision-Making Ritual
Alder energy is decisive. It doesn't waffle. If you have a decision to make that you've been sitting on, use this month's energy to move through it.
Sit quietly with the decision in front of you. Write each option on a separate piece of paper. Hold each one in turn and notice what happens in your body — not what your anxious mind says, but what your body says. The alder tradition teaches that the body knows the answer when the mind is too scared to admit it. After you have your answer, commit to it out loud and burn or bury the paper with the option you're not choosing. Let it go.
Resilience and Endurance Spell
For times when you are under sustained pressure and need to hold on, work with the alder's quality of hardening under water. Fill a bowl with water and submerge a small smooth stone (river stones work well). Hold the bowl and speak into it what you are enduring and what you need to sustain. Ask the water to carry your intention. Leave the stone submerged overnight on your altar. Carry it with you as a talisman of endurance.
Alder is best used in magic that restores balance. You can also use it to inspire harmony, clarity, and confidence. Calling on the spirits of the tree can also restore your inner strength.
Similarly, Druids once used alder cuttings to invoke air elementals. Specifically, they would hollow out the tree's green shoots to make whistles.
The alder symbolizes rebirth possibly because alder buds grow in a spiral pattern.
Fairy Magic
Some of the strongest magic comes from the alder's associations with fairies, though. Alder flowers and twigs are invaluable when communicating with a fairy, and alder fairies are certainly an interesting lot.
Although they're technically Unseelie spirits, the Alder fairies aren't overly hostile. Rather, they're simply protective, but they can cooperate. This is why approaching them with alder twigs is so important.
The alder balances Bran's power with the fairies' magic. It is this balance that really gives it protective powers. The timing of its month just before the spring equinox reminds us of this, as we all need protection and balance in our own lives to face the trials ahead.
Alder fairies are also water spirits. Of course, this makes sense. The trees are most commonly found growing beside bodies of natural water, such as rivers or lakes. Given the fragile state of these environments nowadays, it’s no surprise that alder fairies are so protective.
Overall, these fairies venerate the tree for its role in cosmology, both theirs and our own. Alders symbolize balance most of all, and there's no better balance than continuing the cycle of rebirth. These nature spirits love the tree's strength, as well as its intricacy
If you can get permission though, drinking from the water running by an alder's roots can earn you a fantastic boon. The fairies might grant you foresight, or clarity when making your decisions. Alder water can stabilize and reinvigorate you.
When alder fairies do have to travel, though, they do so in the form of ravens. Make sure to pay the birds extra respects if you're planning to do alder magic shortly or if it's Alder month.

Read Poetry
The gods loved to be read to and Odin and Bran especially love poems. Read your favorite poems or write a poem for them. In the Welsh poem Cad Goddeu (Battle of the Trees), the alder is described as a leader in the battle.
The following poem by Cicely Mary Barker is a beautiful one to start with. Barker was a popular illustrator born in 1895. She created the Flower Fairies (children with wings holding flowers).
The Song of the Alder Fairy
by Cicely Mary Barker
By the lake or river-side
Where the Alders dwell,
In the Autumn may be spied
Baby catkins; cones beside —
Old and new as well.
Seasons come and seasons go;
That's the tale they tell!
After Autumn, Winter's cold
Leads us to the Spring;
And, before the leaves unfold,
On the Alder you'll behold,
Crimson catkins swing!
They are making ready now;
That's the song I sing!
Spells
Alder trees are associated with protection, strength, and the balance between the elements of fire and water. During this month, practitioners of Celtic paganism may choose to work with spells that harness the energies of Alder for various purposes.
Here are a few spell ideas for the Celtic month of Alder:
Protection Spell: Carve a symbol of protection, such as a pentacle or a bindrune for safety, into a small piece of Alder wood. Hold the wood in your hands and visualize a shield of light emanating from it, protecting you from harm. Carry this talisman with you for added protection.
Strength Ritual: Sit quietly under an Alder tree and meditate on the qualities of strength and resilience. Visualize yourself absorbing the tree's strong and sturdy energy. Carry this sense of inner strength with you throughout the month to overcome challenges.
Balance Charm: Create a sachet or charm bag using Alder leaves, combined with herbs like lavender and rosemary for balance. Charge the charm with the intention of balancing the opposing forces within your life, whether it be work and home or emotions and logic. Keep the charm with you or place it in a space where you seek balance.
Spells to aid success in business and academic ventures work well during this month.
Magic Spell for Clarity and Balance
To invoke clarity and balance into your life, gather a purple candle, rosemary, and an amethyst crystal.
Begin by lighting the purple candle, focusing on its calming flame. Take a few deep breaths to center yourself.
Take the rosemary and sprinkle it around the candle in a clockwise direction, envisioning a shield of clarity forming around you.
Hold the amethyst crystal in your dominant hand and close your eyes. Feel its energy pulsating through you, bringing insight and balance to your mind.
Repeat the following incantation:
By the light of this candle so fair,
With rosemary's magic filling the air,
Amethyst's clarity and balance I claim,
In mind, body, and spirit, the same.
Sit in quiet meditation for a few moments, absorbing the energy of your spell and visualizing the clarity and balance you seek.
When you feel ready, extinguish the candle and carry the amethyst with you as a talisman of your intentions.
May clarity and balance be ever present in your journey. Blessed be.
Remember to always approach spellwork with respect and mindfulness, honoring the energies of nature and the elements. May these spells for the month of Alder bring you protection, strength, and balance on your spiritual journey.
Tools
Alder Shields
As a symbol of strength and battle Alder wood is great for making shields. An alder shield will protect you and give you courage. Remember courage and compassion go hand in hand.
Alder Wands
Because alder wood has a connection to all four elements, wands made from alder are particularly versatile. They're especially useful for magic that needs you to balance something, such as your emotions. You can use alder wands for weather magic as well.
For the best results, carve your wand from branches that the wind has blown off the alder tree, not branches that you've cut off yourself. This way the wood's elemental connection is preserved.
Keep in mind that an alder wand can be unpredictable sometimes. You're automatically involving all the elements when using one, so be careful if you're not experienced with that.
Alder Flutes
For the more musically inclined pagans, the month of Alder is a great time to make a flute. Following in the traditions of the druids, you can use your flute to help focus your air elemental magic. Not only that, you can use it to play songs too and celebrate the spring equinox.
Associated with fire, water, and protection. It is considered a, sacred, prophetic tree, often used to create flutes for invoking the wind.
The best flutes come from branches that the wind has blown off the alder tree, such as after storms. This way, the wood has already been infused with the air element. As well, you can collect them without harming the tree itself.
Flutes are also associated with the deity Pan, as is the Alder month. Because of this, it is auspicious to begin this kind of project during this time, especially if you plan to pray to Pan in the future.
Value of Alder Wood
The alder tree's distinctive properties also add to its mysticism. It was a valuable tree for the Ancient Celts and one we still use today.
The alder tree burns at an extremely high temperature. For the Celts who loved their jewelry, this was invaluable for heating the fires of the forge.
However, nobody just cut down an alder tree willy-nilly. In fact, it’s still illegal in parts of Britain to do that. People believed that the alder tree was bleeding when cut because its wood would change from a pale white to a dark orange.
The thick, oily sap also looks like blood. This sap can be boiled down to make syrup.
It became taboo to harm them unless necessary. To do so was to ask for tragedy and chaos in your house. Although alders were felled or naturally fallen, their wood wasn't only used in the forges.
The Celts used alder wood extensively for carpentry, most notably in the foundations of their homes and for their shields. Other parts of the tree they used for medicine, often as a substitute for quinine.
Conservation and Ecology
Alder trees play an important role in their ecological communities. In addition to providing habitats for various land mammals and birds, their nitrogen-rich leaves and roots also contribute to soil health and stability.
Their leaves play another role in the ecosystem too. Alder leaves feed many species of moth and butterfly caterpillars, which discourages them from damaging agricultural crops. Of course, other browsing animals also eat alder leaves, such as the moose.
This is not to say that all is well, however. Although alder trees aren't classified as endangered, they're still vulnerable to parasites like the northern groundcone, a holoparasitic plant native to Canada and Alaska.
Additionally, deforestation has destroyed numerous alder forests, which has significantly destabilized the ecology of those regions and destroyed the lifestyle of the indigenous peoples who harvested from the trees.
Traditional Healing
The alder tree is renowned for its healing properties worldwide. It'd almost be easier to list what the tree can't treat. Alder has traditionally been used to treat coughs, parasites, sprains, toothaches, and strains.
Additionally, you can brew tea or make a poultice from the leaves that'll soothe a sore throat or burns. The bark can also be used to treat inflammation or skin disease and bites and poison oak.
Burning the bark itself can be useful too, as it makes fantastic incense. As well as smelling wonderful, alder bark clears the head and helps you to balance your life. Alder incense is a great choice before major decisions, as well as before exams or interviews.
The History of the Month of Alder
In Celtic legend, the alder is most closely associated with the deity Bran, a Welsh king of Britain. He carried its twigs into battle. Because of all this, the alder was a sign of protection for the Celts. Not only did it symbolize a warrior's strength, the alder was also a symbol of wonder and mystery. After all, it is the tree that fairies love.
Indeed, there's a riddle about Bran's famed connection to this beautiful tree:
Talisan the Poet: Why is the alder tree purple?
Gwydion the hero: Because Bran wore purple.
This is symbolic of Christ’s resurrection made during the middle 500s AD.
Also known as Bran the Blessed, the name "Brân" is Welsh for raven.
Alder in Creation of Man
Irish creation myths tell of how the first man was actually made from alder wood. This association has lasted, and even today the alder has a correspondence with masculine energy.
Simple Ways to Observe Fearn Month
You don't need elaborate rituals to honor this time of year. Here are some grounded ways to connect with the energy of Alder month:
Visit a river, stream, or wetland. Sit with the water. Pay attention to where the land meets the water and what grows there.
Spend time with the alder if there are any in your area. Identify them by their distinctive dark bark, sticky buds, and small woody cones.
Set up a simple altar with red or black cloth, a candle, a bowl of water, and any of the correspondences listed above.
Do something that requires courage this month. Use the energy of the season intentionally.
Honor your ancestors. Speak their names. Leave offerings.
Pay attention to boundaries — where you need stronger ones, where you need to cross one.
