Q.Tomato plants
Two weeks ago I purchased and planted a tomato plant about 18″ tall. It had a small tomato on it then. My question is since that tomato is obviously premature is it stunting the growth of my plant. If so what should I do about it. Just so you know it is planted in a raised bed garden. Thanks

Yes, you can remove that early tomato to give the plant a chance to set good roots.
