Once a plant has matured a little, it will enter the young plant phase. From there it will continue to grow.

  This is a mature plant. When a plant becomes mature, it can be harvested. You can harvest a plant by interacting with it. You can harvest from a plant as long as it's in its mature stage of life once every day or so.

  This is an elder plant, the final stage of a plant's life cycle. Many plants won't reach this stage! An elder plant can be harvested one final time, with much greater possible rewards. Once an elder plant is harvested, it disappears and cannot be revived.

You can choose to remove a plant or dirt pile with the Plow Spell.

Plants have Needs! When your plant has a need, it will let you know. These icons will appear above your plant and you must cast the corresponding spell to fulfill the needs shown. Higher level spells will cast on more than one plant.

Needs water.	Needs sun.
Needs magic.	Needs Music.
Needs pollination.	Has pests!

Your plant may also get pests, both good and bad. Rid your plant of these pests by casting the appropriate spell for the level of the pest. Good pests are rare, and you cannot (nor do you want to) remove them from your plants.
