In my Plant Tycoon game (online demo on game remakes) one of my plants is dropping health. I've never had a plant drop health before. The only reason other than it being a fragile hybrid that I can think of is not enough water. Would Fourpetal Reptans+ Fragrant Reptans be a fragile hybrid? Will it survive to adulthood with the lowest level stuff? If not, I'm in trouble. It has no infestations, and I just watered it. I really don't wanna lose this plant. I have an extra seed, so what'd I do with that if it can't survive? Oh, I need help!

ETA: I'm no longer worried. It's 23 years old and blooming with pretty flowers. Its health isn't full, for which I'm befuddled. Probably the water thing. All is well now.

There are several charts in the Plant Tycoon Guide section that will tell you what cross breeds need which level of soil to thrive. Unless it is an extremely fragile plant, it should survive long enough for you to get seeds and then sell the plant
