Forgot to Tie Your Lulav Before Sukkot 2026? What You Can Do on Yom Tov

Sukkot 2026 begins on Shabbos, and the first time the Four Species are taken is Sunday, September 27. If you forgot to bind your lulav with the hadassim and aravos before candle lighting on Friday, you have not lost the mitzvah. Binding beautifies the mitzvah, but it is not an essential requirement. The important question is how you may put the bundle together on Yom Tov.

Outside Israel, Sunday, September 27 is the second day of Yom Tov. In Israel, Sunday is already Chol Hamoed. This article focuses especially on the Diaspora situation, where the laws of Yom Tov still apply.

First: a lulav does not become invalid because it was not tied

The lulav, three hadassim (myrtle branches), and two aravos (willow branches) are normally bound together. Shulchan Aruch HaRav explains that the binding is a hiddur mitzvah—a way of beautifying the mitzvah—rather than an indispensable part of the mitzvah itself. Forgetting to bind the bundle before Yom Tov therefore does not mean you cannot fulfill the mitzvah.

See Shulchan Aruch HaRav, Orach Chaim 651:3–6.

What you should not do on Yom Tov

If the lulav was not bound before Yom Tov—or if its binding came apart—you should not simply make the same permanent knot that you might have made before the holiday.

Both the standard Shulchan Aruch, Orach Chaim 651 and Shulchan Aruch HaRav discuss this case directly. A lasting knot may not be made on Yom Tov.

So how can the lulav be bound on Yom Tov?

Shulchan Aruch HaRav gives practical alternatives. The species may be secured with a slipknot made with two loops, one over the other. Another method is to wrap the binding material around the bundle and tuck the end into the ring rather than tying a permanent knot.

This is useful to know in 2026 because there is a long gap between Friday afternoon preparation and Sunday morning's first lulav-taking.

Why Friday preparation is still best

The simplest plan is to avoid the question altogether. On Friday, September 25, check your Four Species and assemble the lulav before candle lighting. Many have the custom to bind the lulav on Erev Yom Tov, and some have the custom to do so in the sukkah.

The official 2026 Sukkot Reference Guide likewise lists binding the Four Species among the preparations for Friday, September 25.

What if the bundle comes apart on Shabbos?

Do not repair or rebind it on Shabbos. The Four Species are not taken on Shabbos at all. Put them aside and address the binding after Shabbos, according to the laws that apply where you are.

Outside Israel, Saturday night and Sunday remain Yom Tov, so the Yom Tov knot restrictions discussed above still matter. In Israel, Sunday is Chol Hamoed, so the situation is different.

What if you discover the problem Sunday morning?

If you are outside Israel and discover Sunday morning that your lulav was never bound, do not skip the mitzvah. Use a permitted Yom Tov method of securing the species, such as the methods described above, rather than making a permanent knot.

If the issue is more complicated—for example, a branch broke, a species is missing, or you are uncertain how a particular knot is classified—ask your rav. The laws of knots can depend on exactly how the knot is made and how long it is intended to remain.

FAQ: Forgot to tie a lulav before Sukkot 2026

Is a lulav kosher if it was never tied?

Yes. Binding the lulav, hadassim, and aravos beautifies the mitzvah, but the binding itself is not essential to fulfilling the mitzvah.

Can I make a regular permanent knot on Sunday, September 27, 2026?

Outside Israel, Sunday is the second day of Yom Tov, so a lasting knot should not be made. Shulchan Aruch HaRav gives alternatives, including a two-loop slipknot or wrapping the binder and tucking its end into the ring.

Can I fix the lulav on Shabbos?

No. The Four Species are not taken on Shabbos, and you should not rebind the bundle then.

When should I tie my lulav in 2026?

Preferably on Friday, September 25, before candle lighting. That leaves the bundle ready for its first use on Sunday morning.

Is Sunday the same in Israel and the Diaspora?

No. Sunday, September 27 is the second day of Yom Tov outside Israel, but Chol Hamoed in Israel. That distinction can affect what preparation is permitted.

The practical takeaway

Prepare early: check and bind your lulav on Friday before Shabbos and Yom Tov begin. But if you forgot, the mitzvah is still available to you. Binding is a hiddur rather than an essential requirement, and halachah provides ways to secure the bundle on Yom Tov without making a prohibited permanent knot.

If you still need your Four Species for Sukkot 2026, browse EasyEtrog's lulav and etrog sets and order early enough to have everything ready before Friday, September 25.
