This affects all growth of any and all plants. Saplings, Potatoes, Seeds, Etc/
Unsure if this is related, but saplings won't grow into trees either. I set the random tick speed to 9000 and nothing has grown. Seeing as both plant growth and leaf decay is based on RandomTickSpeed I can only assume these problems are related.
