soil preparation for planting tomatoes in the same bed as last year

Asked March 23, 2013, 12:09 PM EDT

Some of my tomato plants (that were planted in the same bed as the year before) did not produce or even grow. What do i need to do to prep the soil this year before planting tomatoes in the same beds.

Non-producing tomatoes are a big disappointment. This could be caused by diseases, low soil fertility, incorrect soil pH, or a combination of these factors. First, take a soil sample into the OSU Yamhill County Extension Office for a free pH test. Follow their directions for adjusting the pH if necessary. Vegetables in general are heavy feeders, so it is important to annually add a 2 - 3 inch layer of compost or composted manures. Growing plants in the same place year after year allows for a build-up of disease causing organisms. Try planting beans or peas in the tomato area this year. Here is a link to "Preventing Plant Diseases in Your Garden and Landscape" it has full details on crop rotation.

Here is a link to a publication, "Grow Your Own tomatoes" with helpful information on successfully growing tomatoes.

Finally, plan to plant your tomatoes in different spots each year, even if that means planting them in large containers.

Good luck with tomatoes in 2013.
