|I planted several New Zealand Flax two summers ago. They don't seem to be doing well. The leaves are turning brown, and they generally don't look healthy. Could this be the result of some sort of insect infestation? If so, what type of insects have a tendency to invade them?
|New Zealand Flax can become too large and overcrowded and appreciate being dug and divided every few years. Browning leaves can indicate too much or too little water or too much fertilizer. These plants generally do not have any insect pests. It might be time to dig and divide your plants. Cut off the browning foliage, amend the soil with organic matter before replanting, and then water them in well. After a few weeks of adjustment they should grow healthy new foliage. Best wishes with your plants!|
