1. The central axiom

Siman 336 (של"ו) in one sentence.
We do not climb a tree and do not make use of anything attached to the ground — not because climbing is a melachah, but "gezeirah shema yisloch" (lest one come to pluck). The gezeirah grades itself: what is near the tree is assur, the "side of the side" is muttar; walking on the grass — muttar, one isn't aiming at anything.

2. Key concepts condensed

ConceptDefinitionApplication in the siman
שמא יתלוש"Lest he pluck"Reason for the gezeirah on the tree (seif א)
מחובר לקרקעAttached to the groundAssur to use; detached — muttar
דבר שאינו מתכווןUnintentional actWalking on grass — muttar (seif ג)
פסיק רישיהInevitable consequenceWashing hands on the grass = watering — assur (seif ג)
צדי האילןSides / sides of the sides of the treeGradation of the gezeirah (seif יג)

3. Hierarchy of cases

Muttar: walking on grass (fresh or dry), touching the tree without moving it, using a "side of the side", smelling a hadas still attached.
Muttar conditionally: pulling out a plant stuck in the ground erev Shabbos that has not taken root; picking fruit from a branch detached before Shabbos.
Assur (d'rabbanan): climbing a tree, using it, hanging from it — even a dry tree; using a "side" of the tree.
Assur (toldos d'oraisa): plucking (tolesh), planting or soaking grain (zorea), watering by pesik reisha.

4. Decision tree

Q1 — Is the object attached to the ground? Detached → free. Attached → continue.
Q2 — Is it a tree or its environs? Climb / use / "side" → assur. "Side of the side", touch without moving → muttar.
Q3 — Does my act aim to pluck / water? Walking on grass (unintentional) → muttar. Inevitable watering (pesik reisha) → assur.
Q4 — Risk of planting? Seeds in a moist place, soaked grain → assur. Doubt → consult your Rav.

5. The gradation of the gezeirah: from trunk to "side of the side"

The siman rests on a fact one must grasp first: climbing a tree is not a melachah. The issur is entirely rabbinic — a fence (סייג) erected by Chazal out of fear that the person, once in the tree, might come to pluck (גזירה שמא יתלוש). The whole art of the siman is to show that this fence is not uniform: it weakens as one moves away from the point where plucking is tempting.

The three circles: the tree, the "side", the "side of the side"

Halachah distinguishes degrees of distance, and this is the most delicate point to memorize. The tree itself — to climb it, hang from it, use it as a support: assur, because there one is exposed to plucking. The "side" of the tree (צידי האילן) — for example a peg planted in the trunk, which one uses: still assur, because to use it is indirectly to use the tree. But the "side of the side" — to use an object attached to that peg, and not the trunk directly: muttar, since one is now two degrees from the tree, and the fear of plucking has died. The logic: the further the use is from the living tree, the less real the temptation to reach out for a fruit — and the gezeirah faithfully follows this decay.

The tree — climb, hang, use → assur (even an entirely dry tree: the fence targets the kind, not the case).
The side of the tree (peg embedded in the trunk) → assur: to use it amounts to using the tree.
The side of the side (object hanging from that peg) → muttar: two degrees away, no fear of plucking.

The borderline: walking on grass, or the other side of the logic

The same siman addresses a case that seems near but follows an inverse logic: walking on grass. Here the potential issur would be to pluck blades by placing the foot — but walking is muttar, because the plucking, if it happens, is neither willed nor sought: it is a דבר שאינו מתכוון, an unintentional act, and one isn't "aiming" at anything. The boundary is thin: if the act made plucking or watering inevitable, it would swing into פסיק רישיה — a certain consequence — and become assur again. That is why washing hands over the lawn is problematic: the poured water waters by necessity. Walking: one isn't aiming, the grass mostly survives intact — muttar. Watering: the consequence is sure — assur.

To remember: two axes cross the siman. For the tree, measure your distance: trunk and "side" assur, "side of the side" muttar. For the grass, measure your kavvanah: an unaimed act is muttar, an inevitable consequence is not.

6. Mnemonic

אאִילָן: do not climb, do not use — "shema yisloch".

ממְחֻבָּר: what is attached to the ground is assur; detached — muttar.

צצְדָדִין: the gezeirah grades — side assur, side of the side muttar.

אמ"ץ: tree, attachment, gradation of the sides.

7. Pitfalls to avoid

Pitfall 1 — "the tree is dry, so I may". False: the gezeirah targets even an entirely dried-out tree, as a fence.
Pitfall 2 — washing one's hands on the lawn. Walking on grass is muttar (unintentional); but pouring water there waters it — inevitable consequence (pesik reisha), assur.
Pitfall 3 — retrieving an object from the tree. An object placed in the tree before Shabbos may not be retrieved on Shabbos — one would be using the tree.
Pitfall 4 — planting without realizing. Throwing seeds in a moist place, soaking grain in water: toldos of zorea — assur.

8. Modern practical cases

10. The practical pesakim of Siman 336 (של"ו)

For day-to-day conduct

  1. We do not climb a tree and do not use it — even when dry.
  2. Walking on grass is muttar; no watering (pesik reisha).
  3. Attached to the ground: assur to use; detached: muttar.
  4. "Side of the side" and touching without moving — muttar.
  5. Do not plant — seeds in moist place, soaked grain.
  6. In case of doubt — consult your Rav. Pilpul: Level 2; Chabad shitah: Level 4.
