Evelyn and I went to Home Depot and bought two Mexican petunia plants of the same size of 21 centimeters. We transferred the plants to the pots with soil in them. We then took a picture before the fertilizer and measured the plants and recorded the data on a bar graph shown on the Powerpoint. Later we added ½ teaspoon of Jobe’s crystal fertilizer into the pot of plant 1 and added 1 tablespoon of fertilizer into the pot of plant 2. You see we had to double the amount of fertilizer on the second plant to see which one would grow more; the one with the regular amount of fertilizer or the one with doubled the amount of fertilizer. On Wednesday we watered the plants with 1 cup of water poured on top each plant. We then put it in a sunny spot in the backyard. After the first week had ended, on Friday, we had to check on the plants and recorded the data. We also measured the plants and noticed that plant 1 grew half a centimeter and that plant 2 had grown 2centimeters more than its original size. On Wednesday we watered the plants again. Later on Friday we measured the plants again and noticed that plant 1 had grown another half centimeter and that plant 2 grew another centimeter from last time we had measured. Plant 2 had grown faster and larger than plant 1. Plant 1 had also grown throughout this time but at a consistently slow path. At the end of this experiment we had confirmed that due to the fertilizer being doubled the plant had grown more than if you would have put the regular amount of fertilizer on the plant. We believe that if a planter is going to plant a flower they should use double the amount of fertilizer to accelerate the plant growth.
