Hi, I downloaded PT to try (And hopefully buy), but every time I leave the plants for a night I come back to see they are all dead. Am I doing something wrong? I water them before I leave them for the night, but it seems like they become infested in the night or while I'm doing schoolwork, and by the time I can get to them, they die.

What should I do to keep them safe from infestation?

If you can't check on them very often, I would recommend running the game on slow speed. You should also make sure that you're not planting anything except common seeds until you're able to earn enough to buy better soil. Dead plants always look infested, even if that's not the reason they died.

OK, thankyou Mrs. CFII! I'll be sure to check on them and set the speed on slow. And thankyou for explaining the way they look, I thought they only looked like that because they were infected.

EDIT: I discovered the reasons for my plants deaths; I was on fast!

The only surviving plant is a cactus. Wish me and my cactus luck!
