Full Moon vs. New Moon Spells: When to Cast What

Full Moon vs. New Moon Spells: When to Cast What

by Jules of Jules Magick Moon Offerings

As witches, timing is everything. Just as the tides rise and fall, our magick ebbs and flows with the lunar cycle. One of the most common questions I get from clients and fellow practitioners alike is: “Should I cast this spell during the Full Moon or the New Moon?”

So, let’s break it down—witch to witch.

*******

The New Moon: A Blank Canvas

The New Moon is pure potential. It’s that still, dark space before anything takes form—a cosmic reset. This is the moon phase for intention-setting, planting seeds, and beginning new chapters. Think of it as your magickal blueprint.

Best Spells to Cast During the New Moon:

    •    Manifestation spells (especially long-term goals)

    •    New beginnings: job, love, home, spiritual path

    •    Self-development, shadow work, inner healing

    •    Banishing old patterns to make space for the new

    •    Quiet, introspective rituals with soft candlelight and deep intention

Witchy Tip: If you’re starting a long-term spell, cast the first part on the New Moon and allow it to build power as the moon waxes.

 ******

The Waxing Moon: Building Momentum

As the moon grows in light, so does our spellwork. This is your growth phase—magick that expands, builds, attracts, and draws energy toward you.

Ideal for:

    •    Drawing in love, money, opportunity

    •    Confidence, courage, career advancement

    •    Charging tools, talismans, or spirit vessels with positive energy

*******

The Full Moon: Power and Illumination

The Full Moon is the witch’s spotlight. It’s when the veil thins, energy peaks, and all things hidden are illuminated. This is your go-big-or-go-home moment.

Best Spells to Cast During the Full Moon:

    •    Manifestation spells that need a big push

    •    Power charging and spell amplification

    •    Divination, spirit communication, dreamwork

    •    Healing, releasing, cleansing, and letting go

    •    Any spell that requires strong energetic backing

Witchy Tip: Use moon water made under the Full Moon to boost spell power or cleanse your altar tools.

The Waning Moon: Release and Rest

As the moon begins to shrink, it’s time to let go, purge, and cut cords. This is the phase of surrender and closure—perfect for banishing and protective spells.

Ideal for:

    •    Releasing toxic relationships or habits

    •    Protection, warding, hex-breaking

    •    Cleansing your home, body, or spirit

    •    Resting and recalibrating your spiritual energy

********

So, When Should You Cast What?

    •    Need to attract something? New to waxing.

    •    Need to let go or banish something? Waning to New.

    •    Want to charge, empower, or divine? Full Moon, always.

    •    Starting a big spell cycle? Begin at the New Moon, peak at Full, and close during the Waning phase.

Final Thoughts

The Moon is our oldest teacher. She reminds us that magick isn’t about constant output—it’s about rhythm, rest, and realignment. Whether you’re calling in new love under the waxing crescent or releasing heartbreak under the waning gibbous, the moon offers her power freely. All we have to do is meet her where she is.

Blessed be, and may your spells always land with purpose.
