To unlock the "Flower Child" achievement, you must form a flower cluster. The easiest way to do this is by waiting until you see a partially formed one (four or five pieces of the flower already together). Then, just drop in the final piece and you will have created a flower. Flowers are worth alot of points. Whenever you get the opportunity to make one, do so. Note: Do not destroy anything beneath a partially formed flower, or the flower will break apart.
To easily unlock these two achievements, go to Time mode and start a game under the normal difficulty setting. You must get at least one cluster for the clock to start. Do so, then wait for the time (50 seconds) to run out. This counts as a full game. Repeat as many times as needed.
To unlock this achievement, you must form a star cluster. This is very easy; just look for a partially formed star cluster (two pieces) and simply drop the final star piece in whenever one gets close enough to the cluster. Also, the pieces in a star cluster do not need to be the same color; they just need to be star pieces. Forming a star cluster also gives you a large amount of points and usually gives you a big combo. Note: Do not destroy anything beneath a partially formed star cluster, or the star cluster will break apart.
