The levels of gardening skill go from 1 to 10. When you plant a lot of healthy plant varieties, you gradually level-up your skill. So, If the height is green, then your plant is happy and healthy however, if it is red, orange, or yellow, act quickly as that plant requires some tender loving care. Moving your mouse over a plant will show you the progress of its evolution and health by a symbol of the flower with petals.You will need to water them and keep a close eye on your plants as they do need lots of attention. When you click on a plant and choose to produce it, your Sims will grow all plants placed in that area.
You can even choose to plant directly into the ground. You can buy a planter box/pot, then click on it and choose to buy seeds.
