When we'd gone shopping a few weeks ago to get our plants, we had gotten a fully grown tomato plant in a pot from Home Depot.
As the days went by, the plant slowly started dying and we couldn't figure out why. The other plants we'd bought were fine and even the other tomato plant was fine. The leaves of the plant were turning yellow and starting to droop.
The condition of the plant was getting worse and we thought that we had just wasted $15. But I happened to be talking to my friend one day about this plant and she told me that Home Depot has a 1 year warranty on plants and that we could take it back to the store and return it or exchange it.
Luckily, Home Depot had emailed me the receipt and I was able to dig it up in my email. We took the receipt and plant to the store and were able to return it. We bought another tomato plant - a different variety. Now we just have to wait and see how it does.
