According to almanac tradition, roses are planted in the third quarter of the Moon, between the full moon and the last quarter, on a day when the Moon sits in a fruitful or semi-fruitful sign. For 2026 and 2027, that rule gives traditional windows in October and November 2026, March and April 2027, and October and November 2027. The exact days are in the table below.
What the tradition says about planting roses
The almanac sorts every crop into one of three types, then matches each type to a quarter of the Moon’s 29.53-day cycle. Roses fall under the “root” type, a category that also takes in root crops, bulbs and perennials. Gardeners who plant by the Moon therefore treat the third quarter as the roses quarter.
| Crop type | Quarter | Moon phase |
|---|---|---|
| Leafy crops that bear above ground | First quarter | New moon to first quarter |
| Above-ground crops that bear seed inside the fruit | Second quarter | First quarter to full moon |
| Root crops, bulbs, perennials (roses) | Third quarter | Full moon to last quarter |
The fourth quarter, from the last quarter to the new moon, is set aside in the almanac for rest: weeding, pruning, turning the soil and composting. No planting is assigned to it.
A second filter narrows the quarter further. Almanacs label the Moon’s position among the zodiac signs, which it crosses in 27.32 days (one orbit against the stars). Under the common convention, Cancer, Scorpio and Pisces are fruitful, while Taurus, Libra and Capricorn are semi-fruitful. Aries, Gemini, Leo, Virgo, Sagittarius and Aquarius are labeled barren, though sources differ on the last three. The traditional windows for roses on this page are third-quarter days when the Moon is in a fruitful or semi-fruitful sign.
Whether any of this affects a rose is another matter. No effect of the Moon’s phase or sign on rooting, growth or survival has been established. The Moon’s tidal pull at the Earth’s surface is about 1.1 millionths of a meter per second squared at its strongest, roughly one ten-millionth of gravity. That is far too small to move something as small as a seed or a root. What follows is an old custom, presented as one.
Traditional roses planting days, 2026 and 2027
Each row lists the days that meet both tests: third quarter, and a fruitful or semi-fruitful sign.
| Month | Traditional days (Moon sign) |
|---|---|
| October 2026 | October 26-27 (Moon in Taurus), October 30-31 (Moon in Cancer) |
| November 2026 | November 26-27 (Moon in Cancer) |
| March 2027 | March 22-26 (Moon in Libra/Scorpio), March 29 (Moon in Capricorn) |
| April 2027 | April 21-22 (Moon in Scorpio), April 25-27 (Moon in Capricorn) |
| October 2027 | October 16-17 (Moon in Taurus), October 20-22 (Moon in Cancer) |
| November 2027 | November 14 (Moon in Taurus), November 17-18 (Moon in Cancer) |
The months shown are those when gardeners in much of the country plant roses. Your state may start earlier or later, so only the rows that fall inside your own state’s planting window count. A month outside it can be ignored, even if it appears here.
Days are read at noon Eastern time, and the Moon changes sign during the day. Treat the first and last day of each run as soft edges. On a day like March 22-26, where the Moon moves from Libra into Scorpio, the sign label itself changes partway through the run.

Check your state first: when to plant roses where you live
The order of decisions matters. Start with your state’s planting calendar for roses, because that calendar sets which weeks are open to you at all. Once you have that window, the Moon is an optional second step for gardeners who like the custom.
Frost dates and soil temperature decide whether a rose can go into the ground. The Moon, if you follow it, only picks among days the local calendar already allows. It cannot move a planting date earlier, and it should never talk you into a day your local conditions rule out.
Our guide on when to plant roses where you live is the place for dates by state, along with the soil and frost conditions to watch for. This page deliberately gives none of those numbers, because they depend on where you garden and the guide owns them.
Here is a practical way to combine the two:
- Find your state’s planting window for roses in the guide.
- Look at the table above and keep only the rows that overlap that window.
- Within those rows, pick a traditional day that suits your schedule.
- If no traditional day fits the window, plant when the local calendar says to. The tradition has no say over that.
Many windows come in short runs of one to five days, so weather and work often interfere. If a traditional day is missed, the next one is a few weeks away, and the state calendar will tell you whether waiting is an option.
A fair way to try it
If you are curious whether the custom makes any difference in your own garden, a simple side-by-side comparison is the only fair test. Anecdotes from neighbors, or one good season, prove nothing either way.
- Buy two or more roses of the same variety and the same size, and prepare the planting spots the same way.
- Plant half on a traditional day from the table, and half on an ordinary day inside the same week, so weather and local conditions stay as close as possible.
- Label every plant with its planting date and which group it belongs to.
- Water, feed and prune both groups the same way.
- Keep notes: when new leaves appear, when the first bloom opens, and whether each plant is still alive after the season.
One season will not settle anything. Plant-to-plant differences, a sunnier corner or one cold night can outweigh any lunar effect, so a few roses over a single year cannot tell you much. Repeating the comparison over several seasons gives you something to weigh, and it is the only way a home gardener can judge the custom for their own plot.
Questions about planting roses by the moon
Does the tradition say to plant roses in a waxing or a waning moon?
A waning moon. The almanac places roses with the root type, which belongs to the third quarter, after the full moon and before the last quarter. The Moon is shrinking through that stretch. For more on how this phase is treated, see planting in a waning moon. The fourth quarter is also waning, but the almanac reserves it for rest tasks, not planting.
What if the traditional day falls on a frost?
Skip it. The tradition does not override the weather or the calendar of your state. If the ground is frozen or a hard frost is in the forecast, check the rose planting guide for your state, then look for the next traditional day inside your window. If none fits, plant on an ordinary day your local calendar allows.
Do I need to follow the Moon sign as well?
No. The quarter is the older and simpler rule. The sign is an extra layer that some almanacs add, and it is why the table above lists only certain days within the third quarter. If you want the simplest version, use any day of the third quarter that fits your local window. Biodynamic gardening in the Maria Thun tradition sorts the signs differently, into root, flower, leaf and fruit days, and those labels would point to different days than the ones listed here.
