Fertilizing a dormant lawn will not harm it. However, the turfgrass may not receive the full benefit of the fertilizer application. If the granular fertilizer remains on the soil surface because of a lack of rain, some of the material may actually volatilize into the air. It would be best to wait until growing conditions improve before fertilizing the lawn. September is an excellent time to fertilize lawns in Iowa. Lawns can also be fertilized in late October/early November. Why are my tomatoes cracking? Fruit cracking is a common problem on tomatoes. Cracks usually appear at the top or stem end of the fruit.

A heavy rain or deep watering after a long, dry period results in rapid water uptake by the plant. The sudden uptake of water results in cracking of ripening fruit. Generally, fruit cracking is mo
