Crops at plant level 8 and above — start rotting daily
From level 8 your crops decay every day instead of keeping indefinitely. Level one crop at a time from then on so you lose less to rot.

“you've reached the illustrious Level 8 on your plants, something strange has happened”
Our translation: Level 8 row of the crop table: natural decay 2,000
Seed trading with alliance members — is limited to
The higher seed rarities only. Both sources say the two lowest tiers cannot be traded and the two above them can — they use different notation for the tiers, and we do not map one onto the other.

“Green and Blue seeds cannot be traded, while both Purple and Gold can”
pns-mit.org · Japanese
“N,HN の種は種交換で交換することができません。”
Our translation: N and HN seeds cannot be swapped in seed exchange.
The rot is the part people miss
Up to plant level 7 your crops simply accumulate. From level 8 they decay every day, and
nothing in the interface announces the change. Both of our sources call it out independently,
which is usually a sign that a lot of players learned it the expensive way.
What we are not telling you
pns-mit.org says the Cultivation Center unlocks at a specific Command Center
level. No English source we hold states an unlock level, so we do not publish the number.
