Rebirth pays cash and upgrades, then wipes the wall stack so you rebuild. The game has not published a full numbered ladder. Two requirement sets were seen in one session, and they are not a promise that every server shows the same plants.
What one session had to hand over
| When | Plants | Coins | What the session said you get |
|---|---|---|---|
| Earlier rebirth | Apple tree and sunflower | 100,000 | Cash and upgrades. A 5,000 figure shown nearby was the payout of that rebirth, not its price |
| Later rebirth | Peach and lemon | 1,000,000 | Cash and upgrades again. The wall stack still has to be rebuilt |
Keep rolling so those plants are already in the collection when the coins arrive. Guard them. They are stealable, same as any other plant on the plot.
What resets
The built wall stack is wiped. Plan on a new box after the rebirth, using the same tutorial-to-tier order as a fresh base. Plants required for the rebirth are spent as the requirement. The session does not say you lose every other plant, and it also does not say you keep them. Do not assume either.
First buy after the reset
In that session, carry space was bought before new walls. The reason given was practical: more carry space meant more money, which then paid for walls, wire, and the next rebirth. That is one player's order, not a developer rule. The carry-space formula itself is not published.
A better axe was also a cash upgrade in the same stretch of the session. No axe damage or tier list was shown.
How to know you are ready
You are ready for the early set only when the apple tree, the sunflower, and 100,000 coins are all in hand at the same time. You are ready for the later set only when the peach, the lemon, and 1,000,000 coins are all in hand. Missing one plant means you are still in the rolling and guarding phase, not the rebirth phase.
Afterward, expect an empty wall line and a cash bump you should turn into carry space and a new box before you show off a rare plant.
