Gregor Mendel experimented with peas and became the father of modern genetics. The peas, however, do not want to cooperate with me. Actually, they just grew too fast and I needed to transplant them before I could start the experiment. The one pea plant in the MiracleGro (MG) potting soil was growing the fastest - which shows that the cheap soil is cheap for a reason. It may be my imagination, but I feel like the plant in the MG (with the fertilizer) is lanky compared to the plants in the non-fertilized soil. It is difficult to make any conclusion when I have only 1 plant in the MG.
Bucolic Bushwick as a guide. The end product is not as elegant as Elaine's but hopefully it will do the job. I transplanted my peas and put together a simple trellis using bamboo and string. So now I have 2 pots of peas!
