Hi I'm very new to gardening and need help! (This is one of my first vegetables to start.) I purchased an early girl tomato plant at my local farmer's market recently. I planted it in a fabric smart pot (22" diameter and 16" depth). It had two blossoms on it and when I checked on it this morning one of them appears to be closing up. I live in Oklahoma and the daytime temperature has been daytime highs of 77, nighttime low has been 55, and average temp has been 66. Average humidity has been 84%. Can anyone help me with what is going on here before it totally drops?
