Answer: In some cases an excess of nitrogen will result in extra foliage growth at the expense of the blooms. In other cases, the soil may be lacking in some way as you have guessed, but the only way to know for sure is to run some basic soil tests. Your County Extension (664-9502) can help with the tests and with interpreting the results. These plants will also do best in full sun all day long. Finally, water is very important in flower production. Your plants should be receiving about an inch a week from the hose or the sky, and a deep watering is more effective than light daily sprinkings. Finally, a mulch is also useful for both weed control and moisture retention.
