it isn't hard if you click on the plant it has the water gauge in the verticle word WATER....when it gets down around the e-r you should water again.....as for the magic plants you can breed them or sometimes get lucky with a seed from the store....the chart in the virtual seed tray can tell you what plants you need to have to breed any of the plants magic or not. There is no sure fire answer to what you should do on that score...if a plant can't survive in the soil you are using its health will drop but you can usually self pollinate it harvest the seeds and sell it before it becomes to unhealthy to sell than just store the seed til you have better soil....the fixing up of the nursery mainly just attracts more visitors. it is usually the last thing i do i get the seed trays, better soil and water, nippers than the nets first in that order. when you upgrade something in the nursery you don't have to select a spot it goes to where it belongs all you do is spend the money to do it buy it and it is placed for you. So don't be afraid of the game just have fun. and grow and sell the plants. Don't let the charts and spreadsheets scare you. you don't need them to play the game it just makes breeding the different plants easier.
