Full Moon Spell Timing: Cast These 7 Spells During Waxing Versus Waning Phases

The full moon isn't actually when most powerful spells happen—and I know that contradicts everything you've probably seen on Instagram. The truth is far more nuanced and, honestly, more empowering: the moon's gravitational pull influences tides by 2-3 feet, and practitioners for centuries have worked with all lunar phases, not just the obvious one. A waxing moon (the 14 days when the moon grows from new to full) is ideal for building energy—attracting love, abundance, confidence, protection from external threats. A waning moon (the 14 days after the full moon shrinks back to new) excels at releasing what no longer serves you: breaking habits, banishing negativity, ending relationships, reversing hexes. The difference isn't spiritual preference; it's about working with natural cycles instead of against them. This article breaks down exactly which of your 7 most-wanted spells belongs in which phase, what you'll actually need to cast them (spoiler: less than you think), and how to read the moon calendar so you never cast a spell at the wrong time again. By the end, you'll understand why timing matters more than fancy tools.

Understanding Lunar Phases: The Complete Map

Before we talk spells, let's map the moon's actual journey. Each lunar cycle lasts 29.5 days—that's the time it takes the moon to orbit Earth and return to the same position relative to the sun. Practitioners divide this into 8 traditional phases, but for spell work, you really need to know 4: New Moon (completely dark, invisible), Waxing Moon (growing toward full, roughly days 1–14), Full Moon (100% illuminated), and Waning Moon (shrinking back to new, roughly days 15–29). Some traditions add “Dark Moon,” which technically happens 1–3 days before the New Moon and has slightly different energy—more introspective, more suited to shadow work and deep divination.

The waxing phase is called “growing” or “increasing” energy. As the moon fills with light, you literally see more of it each night. This visible expansion mirrors the intention you're building: bigger, brighter, more present. Tarot readers and witches have worked with this correspondence for at least 400 years, with written evidence in grimoires dating to the 17th century. The waning phase does the opposite: the moon visibly shrinks each night, mirroring the intention to reduce, banish, or release. This isn't mysticism divorced from observation—it's practical symbolism built from pattern recognition.

Here's what often confuses beginners: the full moon itself is traditionally considered part of the waning phase, not a separate category. Technically, the moon begins to wane the instant it reaches fullness. However, many practitioners treat the full moon (the 1–3 days of peak illumination) as its own power window because its effects are so concentrated. Think of it as the climax of the waxing energy, with all that accumulated power released in one burst. For spell work, you have about 3 days of genuine full moon energy—the night before, the night of, and the night after maximum fullness. Check a lunar calendar (like those at lunascircle.com/moon-calendar) to see the exact timing for your location, since the full moon can peak at different times depending on your timezone.

Spell #1: Love & Attraction Spell (Waxing Moon)

A waxing moon spell for love works because you're literally growing the energy of connection toward the person or toward the vibration of love itself. This spell is safe, straightforward, and works whether you're calling a specific person or calling in the general energy of being loved and desired. The traditional version uses rose petals, but any flower—even grocery store carnations—works. You don't need a fancy $40 crystal wand; a rose quartz stone the size of your thumb costs $2–5 online, or you can skip stones entirely and use your fingers.

Here's the spell: On any night during the waxing phase (ideally 3–10 days before the full moon, when the moon is visibly growing), light a pink or red candle. Pink is softer, for gentle attraction and self-love; red is intense, for passionate romance. Hold the candle for 10 seconds, feeling its warmth, and speak aloud: “As this moon grows full and bright, so grows [your intention: my confidence, my magnetism, this love, my openness to connection].” Then either drop rose petals into a bowl of water (or a bath you'll use), or burn them safely in a fire-safe dish. The smell is immediate and grounding—that's your cue that the magic is active. Blow out the candle (don't pinch it; blowing carries your breath-energy) and repeat this every 2–3 nights until the full moon, or just once if you're short on time. One repetition works; multiple repetitions amplify.

Materials needed and affordable alternatives:

• Pink or red taper candle (99¢ at any grocery store, lasts 4–6 spells)
• Rose petals—fresh or dried ($3–8 online; grocery store florals work fine)
• Rose quartz stone (optional, $3–5 online)
• Fire-safe dish if burning petals (a ceramic bowl works; never use plastic)
• Matches or lighter (you already own one)

Total cost: under $5 if you already have candles and a lighter. Why waxing and not waning? You're building attraction energy, not removing it. Waning moon spells for love relationships focus on breaking unhealthy patterns or releasing an ex's hold on you—the opposite goal. Waxing = magnetize. Waning = banish.

Spell #2: Banishing & Breaking Habits (Waning Moon)

The waning moon is your best friend if you're trying to quit smoking, stop doom-scrolling, end a toxic friendship, or break any pattern that doesn't serve you. This phase is about consciously choosing less, and the moon's visible shrinking mirrors that choice. A 2020 study by researchers at the University of Basel (published in Frontiers in Neuroscience) didn't directly study witchcraft, but it confirmed that humans have measurably different sleep and energy cycles tied to lunar phases—proof that moon cycles do influence our biology, even if we're not consciously tracking them.

The banishing spell is simple and deeply satisfying. Anytime during the waning phase (the 14 days after the full moon), write on a piece of paper what you want to remove from your life: “I release my dependence on my phone.” “I banish anxiety from my daily practice.” “I let go of my fear of abandonment.” Be specific; vague intentions get vague results. Light a black or dark purple candle (or use whatever color you have—intention matters more than pigment, and this is a common misconception). Hold the paper near the flame, speaking: “As this moon wanes to dark, so wanes [habit/energy] from my life. I am free. I reclaim my power.” Then burn the paper safely in a fire-safe dish, watching it turn to ash. That ash you can scatter outside, bury in soil, or flush down the toilet—the point is that the written intention is transformed from solid to smoke, symbolizing its release from you. Many practitioners report feeling noticeably lighter after this spell, which makes sense psychologically: you've made a conscious, ritualized decision, and ritual reinforces behavior change in your brain.

Materials and cost breakdown:

• Black, dark purple, or brown candle (same sources as above, 99¢)
• Paper and pen (you own these)
• Fire-safe dish or bowl (ceramic, glass, or metal only)
• Matches or lighter

Total cost: under $1. Timing matters here: do this spell in the last 7 days of the waning phase (the final week before the New Moon) for maximum “closing” energy. You can do it anytime during the waning phase, but the closer to the New Moon, the more “final” the release feels. Never do this during the waxing phase—you'd be accidentally building what you're trying to banish.

Spell #3: Abundance & Prosperity (Waxing Moon)

Money magic gets a bad reputation in some spiritual circles, as if desiring financial security is materialistic or anti-spiritual. It's not. You need money to live, and there's nothing shameful about drawing it in. The waxing moon is perfect for this because you're literally watching abundance grow each night. This spell works for attracting a job, a raise, passive income, or unexpected money (like inheritance or a tax refund). The traditional tool is a green candle, but yellow also works for prosperity and optimism, and white works as a universal placeholder.

During the waxing phase, gather coins or bills—even one penny counts—and arrange them in a circle on your altar or a clean table. If you don't have an altar (most beginners don't, and that's fine), any dedicated surface works: a shelf, a windowsill, even a small wooden tray. Light your green or yellow candle in the center of the coin circle. If you have dried basil, mint, or bay leaves, sprinkle a tiny pinch on the candle's flame (be careful—only a pinch, and never leave a candle unattended). The scent is sharp and grounding. Speak your abundance intention aloud three times: “I attract [specific amount or type of money] into my life. I am worthy of prosperity. Money flows to me easily.” Sit with the candle for 5–10 minutes, visualizing the money arriving—the feeling of relief, the things you'll buy, the freedom it brings. This visualization is the spell's engine; the candle, coins, and words are just focusing tools. Repeat this every 2–3 nights during the waxing phase, adding one new coin to your circle each time to literally grow your abundance pile.

Supplies and cost:

• Green or yellow candle ($1–2)
• Coins from your pocket (free)
• Dried basil, mint, or bay leaf (optional; $2–3 per container if you don't have them, lasts 50+ spells)
• Matches or lighter

Total cost: under $2 if you already have candles. Why this works: you're combining focused intention (your words), emotional resonance (your visualization), symbolic action (growing the coin pile), and timing (waxing energy). Neuroscientific research on visualization shows that the brain's reward centers light up identically whether you're imagining earning money or actually earning it—so this visualization isn't “fake”; it's priming your nervous system to recognize and act on opportunities.

Spell #4: Protection Spell (Any Phase, Best on Waxing)

Protection magic is different from banishing because you're not trying to remove something; you're building a shield around yourself or someone else. White light protection can be done on any moon phase, but the waxing moon amplifies it because you're literally strengthening the barrier each night. This spell is essential if you're empathetic, work in healing professions, or spend time around emotionally draining people. Many practitioners don't realize they need this spell until they're exhausted without knowing why—that exhaustion is often emotional or energetic, not just physical.

For a personal protection spell during the waxing phase, light a white, silver, or clear quartz candle. If you have salt (table salt is fine), make a small circle around the candle with it—salt has been used as a protective barrier in cultures worldwide for at least 2,000 years. Speak: “I am surrounded by white light. I am protected from harm, negativity, and drain. My energy is my own. Nothing can penetrate this shield.” Sit for a few minutes and imagine white, golden, or silver light surrounding your body like a bubble. If you're protecting another person (a child, a friend, a pet), visualize that same light around them. Do this every night during the waxing phase, and you'll likely notice you feel calmer and less “permeable” to others' emotions within 2–3 days. Some practitioners report fewer headaches and better sleep simply because they're no longer unconsciously absorbing others' stress.

You can also make a physical protection charm: write your name on a small piece of paper, place it in a small cloth pouch with salt, dried rosemary (a traditional protection herb), and any protective crystal (black tourmaline, smoky quartz, or even a plain stone from outside). Carry this in your pocket or bag during the waxing phase, and the spell's energy refreshes daily. This version is ideal if you can't light candles at work or home.

Supplies needed:

• White, silver, or clear candle ($1–2)
• Salt (you already have this)
• Optional: small cloth pouch ($1–3), dried rosemary ($2–3), protective crystal ($3–10 or found outside for free)
• Matches or lighter

Total cost: $1–3 for candle version; $5–10 if making the portable charm. Protection spells are uniquely scalable—you can do the bare-minimum version (light a candle, speak the words, done) or build the full charm. Both work.

Spell #5: Confidence & Self-Love (Waxing Moon)

Self-love spells are often dismissed as less “serious” than money or protection magic, but confidence is the foundation of every other spell working. You can't attract a partner if you don't believe you're worthy of love. You can't manifest money if you secretly feel you don't deserve it. This spell rebuilds your internal power. The waxing moon is ideal because you're literally growing your own light and presence each night. This spell is particularly powerful done during the days just before your birthday or a personal “new year” (like the start of a new job or ending of a relationship).

During the waxing phase, on the night of a full or growing moon, look at yourself in a mirror—actually look, not just glance. Light a yellow or gold candle in front of the mirror or nearby. You might feel awkward or sad doing this, especially if you struggle with self-image. That's normal and exactly why the spell is needed. Speak directly to your reflection: “[Your name], I see you. I honor your strength. I celebrate your weird, beautiful, imperfect self. You are enough as you are.” Say it three times. Then list three things you did well that week—three things, no matter how small. Maybe you showed up to work even though you were tired. Maybe you made a meal. Maybe you didn't yell at someone who frustated you. These count. Say each one aloud. This forces your brain to acknowledge your own competence, which it regularly overlooks because we tend to dismiss our wins while amplifying our failures. Repeat this spell every 2–3 nights during the waxing phase, and many practitioners report feeling noticeably calmer and more assured by the time the full moon arrives.

The biochemistry here is straightforward: speaking affirmations aloud activates different neural pathways than thinking them silently. Combined with the mirror (which forces you to take yourself seriously rather than scrolling past your own image on a phone), you're rewiring your self-perception in real time. The moon phase simply provides a structure and a timeframe that makes the practice feel sacred rather than self-help-y.

Supplies:

• Yellow or gold candle ($1–2)
• Mirror (you already own one)
• Matches or lighter

Total cost: under $2. This spell costs almost nothing because the real work is internal.

Spell #6: Ending & Closure (Waning Moon)

Not all waning spells are about “banishing” in the dramatic sense. Some are about gentle closure—finishing a creative project, ending a chapter of your life peacefully, or completing a relationship with gratitude rather than resentment. This spell is for people who are leaving a job they loved, moving away from a community, or consciously ending a friendship that no longer fits. It's also powerful if you're grieving and need to ritually say goodbye to someone who's passed on. The waning moon's energy of natural conclusion is perfect for this.
