Why are tomatoes turning black (dark) from the bottom up when they begin to ripen. They are also dark on the inside.

The condition that you are seeing is called blossom end rot. Blossom-end rot is a physiological disorder caused by a calcium deficiency in the young fruit. Utah soils have plenty of calcium so even though technically it is the problem, the real issue is fluctuation in the amount of water available to the plant that makes the plant unable to transport the calcium as needed. Tomatoes, squash, peppers, eggplants and melons are all vulnerable to this problem. The good news is that normally only the first few fruits to ripen are damaged.
There are a couple of different things that you can do to help prevent this condition. Overwatering your plants can aggravate this condition, especially if your plants are in a heavier clay soil. Keep a close eye on how much water you apply and how much moisture is in the soil. Mulching around your plants can also help to reduce the amount of water lost to evaporation and can help keep soil moisture levels more consistent. In addition, over fertilizing your plants can also contribute to this condition. I have included a link below to our tomatoes fact sheet.

- The last few years, I have had persistent grass growth in my vegetable garden. I till the area each fall and spring, and pull out and discard all the vegetable plants. For the first couple of months, its easy to control the weeds and grass, then about 2/3 of the way through the summer, the grass starts to take over. By the time I pull out the plants in the fall, I practically have a lawn underneath them. Now that everything is pulled up, should I spray Round-up or another grass killer on the entire garden area? Or is there a better way to control the grass?
