According to almanac tradition, peas are a second-quarter crop. They go in between the first-quarter Moon and the full Moon, on days when the Moon is in a fruitful or semi-fruitful sign. For 2027, that gives traditional windows of February 17-18, March 16-17, April 19-20, September 9-10 and September 14-15. No effect of the Moon on peas is proven, and your state’s calendar comes first.
What the tradition says about planting peas
The almanac rule
Gardening almanacs sort crops into types and match each type to a stretch of the Moon’s cycle. Peas fall under “fruit,” meaning above-ground crops that bear seed inside the fruit. The almanac rule is to sow that type in the second quarter, from the first-quarter Moon to the full Moon. This is the same logic behind planting by the moon in general.
Gardeners who plant by the Moon often narrow the choice further with the Moon’s sign. This convention labels Cancer, Scorpio and Pisces fruitful, and Taurus, Libra and Capricorn semi-fruitful. The other six signs are labeled barren, though almanac sources differ on Virgo, Sagittarius and Aquarius.
| Crop type | Almanac quarter | Examples in the almanac lists |
|---|---|---|
| Leaf | First quarter (new moon to first quarter) | Lettuce, spinach, cabbage, broccoli, celery |
| Fruit (peas) | Second quarter (first quarter to full moon) | Tomatoes, peppers, beans, squash, corn |
| Root | Third quarter (full moon to last quarter) | Potatoes, carrots, garlic, onions, beets |
The fourth quarter, from the last quarter to the new moon, is a rest period in this tradition. It is set aside for weeding, pruning, turning the soil and composting rather than sowing.
What is not proven
No effect of the Moon’s phase or sign on peas, or on any other crop, has been established. The phase cycle runs 29.53 days, and one orbit against the stars takes 27.32 days, which is the cycle the sign calendar follows. 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 anything as small as a seed or a root. Read everything below as custom, a calendar some gardeners enjoy keeping, and not as a mechanism.

The windows
Each row below combines the quarter rule with a fruitful or semi-fruitful Moon sign. Days are read at noon Eastern time (ET).
| Month | Traditional days | Moon sign | Label in this convention |
|---|---|---|---|
| February 2027 | February 17-18 | Cancer | Fruitful |
| March 2027 | March 16-17 | Cancer | Fruitful |
| April 2027 | April 19-20 | Libra | Semi-fruitful |
| September 2027 | September 9-10 September 14-15 |
Capricorn Pisces |
Semi-fruitful Fruitful |
How to read the rows
The months shown are those when gardeners in much of the country plant peas. Your state may start earlier or later, so only the rows that fall inside your own state’s window count. A row outside that window is not a planting date for you, whatever the Moon is doing.
The Moon changes sign during the day, while each day here is read at a single moment, noon ET. Treat the first and last day of each run as approximate edges. If a run starts or ends close to the sign change, the Moon may be in the neighboring sign for part of that day.
Gardeners west of the Eastern time zone should keep the same clock in mind. A change of sign that lands in the evening on the East Coast arrives earlier in the afternoon in Pacific time.
Check your state first: when to plant peas where you live
The order of decisions matters more than the Moon. Start with your state’s planting calendar for peas. That calendar tells you which weeks are open for sowing where you live. Only after that, if you want to follow the tradition, do you look at the Moon.
The Moon never overrides the calendar of the place. Frost dates and soil temperature decide whether peas can go in the ground. If you follow the Moon, it only chooses among days that are already open, and it does nothing to open a closed one. A traditional day in a month your state has not reached is not a reason to sow.
Our guide on when to plant peas where you live covers the calendar side. It owns the planting dates, soil conditions and frost timing, so this page does not repeat them. If you want to see how your state compares with its neighbors, the state guides collect the local planting information in one place.
Once you have your state’s window, put the table above next to it. Some states will overlap with only one or two of the traditional runs, and others may overlap with none of them. If no run lands inside your window, the tradition simply has nothing to offer for that stretch, and your own calendar stands on its own. The same applies to a run that begins before your window opens. In that case, wait for the part of it that falls inside.
A fair way to try it
Nothing on this page can tell you whether the tradition does anything for your peas. A home gardener can only judge it on their own plot, and the simplest way is a side-by-side comparison.
- Pick a week that sits inside your state’s planting window and holds one of the traditional runs. Split your peas into two equal plantings, one for each type of day.
- Sow half on a traditional day. Sow the other half on an ordinary day in the same week, using the same seed, soil, depth and spacing.
- Label both plantings with the date and the type of day, so the markers are still readable weeks later.
- Write down when seedlings first appear in each planting, and again at harvest, noting how much each one gives.
A single season will not settle anything. Weather, shade, soil and seed lots all differ from one row to the next, and one year of notes is too little to separate those from any Moon effect. Several seasons of notes give a clearer picture, though even they will not prove a cause. What you get is a record from your own garden, which is the only kind of evidence a home gardener can collect.
Questions about planting peas by the moon
Does the tradition say to plant peas in a waxing or a waning moon?
Waxing. The almanac rule puts peas in the second quarter, between the first-quarter Moon and the full Moon, which falls inside the waxing phase. Our page on planting in a waxing moon explains how the almanacs treat that half of the cycle. The waning half, after the full moon, is assigned to root crops and then to rest.
What if a traditional day falls on a frost?
The tradition has no answer for that, because it was never meant to overrule the local calendar. If your state’s guide says the ground is not ready on that day, skip it. Wait for the next traditional run, or sow on an ordinary day inside your state’s window.
Do I need to follow the Moon sign as well?
Only if you want the stricter version of the tradition. The quarter rule alone gives you a wider set of days, and the table above adds the sign filter on top of it. Biodynamic gardening, following Maria Thun, uses a different system. It groups the signs into root, flower, leaf and fruit days, and its fruit days are Aries, Leo and Sagittarius. Those are not the signs used in the table, so the two methods can point to different days for the same crop.
