Plant Diseases and Growth Issues in Bromeliads 1 Water DeficiencyInadequate irrigation has been linked to poor growth and bloom. Part 2 of Pests and InsectsThe plant's leaves and blooms are frequently nibbled off by Mexican bromeliad weevils, which have a long red or black body and two or three prevalent illnesses. These insects initially feed on the leaf underside before moving on to the next flower. Once they reach the petal area, they will feed on the pollen and then move on to another flower.
Bromeliads are susceptible to many of the same diseases and pests that affect other plants. We recommend that you take the following precautions to help prevent disease and damage to your bromeliads:
1 Provide adequate water during dry periods. If necessary, use a soaker hose or drip irrigation system to supply moisture when needed.
2 Clean up any debris around the base of the plant. This includes fallen leaves, twigs, and even nails that may be near the ground. Any material that can serve as shelter for insects should be removed.
3 Control insect populations directly associated with your bromeliads. For example, Mexican bromeliad weevils like warm temperatures and high humidity, so ensure that your house is not being used for pest control during hot summers or when it is cold outside. You can also try introducing parasitic wasps into your yard to control beetle populations.
Troubleshooting Bromeliad Issues
The most prevalent reason of yellowing leaves in bromeliad plants is insufficient soil moisture, specifically overwatering. Water your plant just when the dirt in the pot is nearly dry. It is critical that any surplus water in the saucer be discarded and that your plant not sit in any standing water. Bromeliads do not like to be wet for long periods of time or even occasionally so make sure you provide them with a stable environment where they can grow and develop without stress.
If your bromeliad is growing in an environment where it receives sufficient sunlight but is still producing yellow leaves, there may be some insects feeding on the plant. Check the foliage for any signs of insect damage such as small holes where bugs have eaten into the leaf tissue. If you find evidence that insects are harming your bromeliad, take the plant out of its current environment and put it in a protected location until the problem has been dealt with. Do not try to control insects yourself because they can easily spread disease as well.
Finally, if your bromeliad's leaves are completely brown and falling off, it may be suffering from low levels of oxygen. Make sure there are no broken stems and that the root ball is not exposed at the bottom of the pot. If you notice any damage to the plant, immediately move it outside into partial shade. Let the plant air out and wait until new growth appears before re-potting into a larger container.
Your bromeliad can burn if it is placed in a window that receives too much direct sunlight. The presence of brown tips or light brown specks on the leaves indicates that the plant is receiving too much sunlight. When relocating a bromeliad outside for the summer, take care not to expose it to too much direct sunlight. If necessary, move it into a shaded area during the hottest hours of the day.
The tips of the plants organs, including leaves and shoots, will turn brown when they are not getting enough air. This is called desiccation and it is one of the main causes of death for many plant species. Bromeliads are very sensitive to drought so make sure to give them enough water during the dry season. You should water the plant at least once a week during the dry period. Drought also causes the nutrients in the soil to leach out which makes it harder for the bromeliad to grow.
If you notice that your bromeliad is losing its coloration up towards its crown, this could be an indication that it needs to be repotted. As long as the roots of the plant are growing and there are no signs of disease, then your bromeliad is healthy. However, if it has been sitting in the same pot for several months or longer, then it may need to be moved to allow it to find new growth.
