| Sirs, Around the first week of October I purchased 4ea of the 6 |
| You were right to check the weather to see if low temperatures might have been responsible for the color change on the foliage. A frost can do that to some plants. But, since mums are reasonably cold tolerant, it's not the likely cause of the coloration change. More likely it's a nutrient deficiency. I'm sure your plants were fed on a regular basis before you purchased them and it sounds as though they need to be fed every 2-3 weeks while they are in bloom. Choose a bloom booster (one that is high in phosphorous and potassium) and apply in amounts as recommended on the label, which will vary depending upon the sizes of your containers. The phosphorous will help keep the leaves from turning a reddish purple and will also encourage flower bud development. The potassium will help strengthen the stems and encourage root growth. Best wishes with your mums! |
