Hi web world I have a few Questions for you all re: my seasonal impatient garden. Two years ago I moved into this home and planted some Imp. (FOR SHORT). They were breathtaking big beautiful blooms and I was so proud. Last year I did all petunias good job but I decided to go back to imps. This time the plants are just so-so it is hard to get them to grow and flower. Seems they have buds but only flower once or twice. They are very small as well. I am watering and I have sprinkled fertelizer once. I do have some sunflowers about 3 feet behind them. Could they be taking Nutrients? This year I did not mulch due to lack of money could that help ? What am I doing wrong? Thank you all in advance for your response.
