According to almanac tradition, lettuce is a leaf crop, and leaf crops are planted in the planting by the moon first quarter, the stretch from new moon to first quarter. Gardeners who also follow the Moon’s sign look for Cancer, Scorpio or Pisces, or for the semi-fruitful signs Taurus, Libra and Capricorn. The days from October 2026 through October 2027 are in the table below. No effect of the Moon on lettuce has been proven, so read all of it as custom.
What the tradition says about planting lettuce
The almanac rule is short. Almanacs sort crops into three types by where the harvest grows, and lettuce lands in the leaf type: leafy crops that bear above ground, plus crops whose seed is outside the fruit. Spinach, cabbage, broccoli and celery share the group. The rule puts the whole type in the first quarter, the two weeks or so between new moon and first quarter.
Whether any of this affects a lettuce seedling is another matter. No effect of the Moon on lettuce is proven. The tradition is a way of picking among days, and nothing more has been established.
| Crop type | Examples | Almanac quarter |
|---|---|---|
| Leaf (lettuce) | Lettuce, spinach, cabbage, broccoli, celery | First quarter, new moon to first quarter |
| Fruit | Tomatoes, peppers, beans, squash, corn | Second quarter, first quarter to full moon |
| Root | Potatoes, carrots, garlic, onions, beets | Third quarter, full moon to last quarter |
The fourth quarter, from last quarter to new moon, is the almanac’s rest period. It is kept for weeding, pruning, turning the soil and composting rather than sowing.
How the windows are built
The phase cycle takes 29.53 days, so the first quarter comes around once per cycle. The sign layer is separate. The Moon circles the sky against the stars in 27.32 days and passes through each sign in turn. A common convention in moon-sign almanacs labels Cancer, Scorpio and Pisces fruitful, Taurus, Libra and Capricorn semi-fruitful, and Aries, Gemini, Leo, Virgo, Sagittarius and Aquarius barren. Sources differ on Virgo, Sagittarius and Aquarius.
The days in the next section are those where both conditions line up: first quarter, and a fruitful or semi-fruitful sign. The first quarter is the opening half of the waxing moon. For the broader rule, see planting in a waxing moon.
What the Moon can and cannot do
The Moon’s tidal pull at the Earth’s surface is about 1.1 millionths of a meter per second squared at its strongest. That is roughly one ten-millionth of gravity. It is far too small to move anything as small as a seed or a root.
Traditional lettuce planting days, 2026 and 2027
The windows, month by month
Each row lists the traditional days for a leaf crop, with the Moon’s sign. A slash between two signs means the Moon changes sign during the run. For a day-by-day look at the first window, see the October 2026 moon calendar.
| Month | Traditional days (Moon sign) |
|---|---|
| October 2026 | October 10-13 (Moon in Libra/Scorpio) October 16-18 (Moon in Capricorn) |
| March 2027 | March 8 (Moon in Pisces) March 11-13 (Moon in Taurus) |
| April 2027 | April 8-9 (Moon in Taurus) April 12-13 (Moon in Cancer) |
| May 2027 | May 6 (Moon in Taurus) May 9-10 (Moon in Cancer) |
| August 2027 | August 6-8 (Moon in Libra/Scorpio) |
| September 2027 | September 2-5 (Moon in Libra/Scorpio) September 30 (Moon in Libra) |
| October 2027 | October 1-3 (Moon in Libra/Scorpio) October 6 (Moon in Capricorn) October 29-30 (Moon in Scorpio) |
The months shown are an approximation of when gardeners across much of the country plant lettuce. Your state may start earlier or later, so only the rows that fall inside your own state’s window count.
Reading the edges
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. A run listed as October 10-13 may begin or end a few hours either side of those dates, depending on the hour of the sign change and where you live. Gardeners in the Mountain or Pacific time zones will see the changeover land at a different clock time than the Eastern one used here.
Single-day entries, such as March 8 or September 30, are the narrowest windows in the table. If your schedule cannot meet one, the tradition simply offers the next run.
Check your state first: when to plant lettuce where you live
The order of decisions
The Moon comes second. Frost dates and soil temperature decide whether lettuce can go in the ground where you live. If you choose to follow the Moon, it only picks among days the local calendar already allows. It never overrides that calendar.
So begin with your state’s planting calendar. The page on when to plant lettuce where you live covers the dates, and the state guides go into the local detail for each state. Those pages own every practical number. This one does not repeat them.
Then, if you want it, the Moon
Once you have your state’s dates in hand, lay them over the table above. Cross out every row outside your window. What remains is a short list of traditional days, and in some states and months it may be only one or two. In others the list will be longer, and you can pick the day that fits your schedule.
A row that falls outside your state’s window is not worth waiting for, however neatly it fits the quarter and the sign. The almanac gives a preference among days. It has no way to move a planting season. A gardener who treats the table as permission to sow outside the local calendar has read the tradition backwards.
A fair way to try it
Almost every claim about planting by the Moon rests on memory and anecdote. A gardener who wants to know whether it makes any difference on their own plot has one honest method: a side-by-side comparison.
- Choose one lettuce variety and one bed, or two beds with the same soil and the same sun.
- Plant half the seed on a traditional day from the table that also falls inside your state’s window. Plant the other half on an ordinary day within the same week.
- Label both halves with stakes or tags that name the date and the reason, either “tradition day” or “ordinary day.” Water and care for them the same way.
- Write down the date seedlings first appear in each half, then the date of the first harvest, and a note on how each half looked.
One season will not settle anything. Weather varies from one week to the next, and a small difference between two rows could come from a shaded corner, a patch of drier soil or plain chance. Several seasons of notes, kept the same way, would tell you more. Even then, what you learn applies to your plot and not to anyone else’s.
Questions about planting lettuce by the moon
Does the tradition say to plant lettuce in a waxing or a waning moon?
Waxing. The almanac rule places leaf crops in the first quarter, between new moon and first quarter, while the Moon is growing toward full. The waning half of the cycle is assigned to root crops in the third quarter and to rest in the fourth. This is almanac tradition and no effect has been proven.
What if the traditional day falls on a frost?
Then skip that day. Your state’s calendar and the weather at your place come before any Moon rule, and the tradition does not ask you to plant against them. Look at the next row in the table that falls inside your state’s window, or consult the lettuce planting dates for your area and choose again.
Do I need to follow the Moon sign as well?
No. Some almanacs use the quarter alone. Others add the sign as a second filter, which is what the table above does, keeping only days when the Moon is in a sign this convention labels fruitful or semi-fruitful. A separate system, the biodynamic calendar of Maria Thun, sorts days by element instead and calls Cancer, Scorpio and Pisces leaf days. It does not use the quarter rule in the same way. Pick one approach and keep it for the whole season so your notes stay comparable.
