To upgrade your plants' stars, you must get Puzzle Pieces (the ones with the whole plant in it) and put them on The Scale. This will be a very hard work, so try to obtain some three-starred plants from daily rewards.

Upgrade your plants' levels by using Green Beans from the Sunflowers in Zen Garden or play again the previous levels.

Upgrade your plant's roman numeral level by putting them in The Oven. It gonna needs some potions, which you can get from daily rewards, and exchange them to upgrade plants with higher stars.

Give plants costume, which can be bought by gems. The easiest way to get gems is the boxing arena. Try to upgrade your level by getting more EXP to unlock that arena.

Give plants equipments, which can be obtained by getting some... sort of white stones which can be obtained from Road of Trial.
