Flowers & Gardening 0 views
There are many reasons that cause yellow spots on the leaves of a Guzmania: if it is caused by improper watering, then you need to water it properly, avoid pouring water into the flower center, and make sure the potting soil stays moist and never dries out; if it is caused by unsuitable temperature, then you need to control the plant's growing temperature, keep it constant, and make sure the temperature difference is not too large.

1. Improper watering

1. Cause: This kind of plant is very sensitive to water content, and improper watering will directly affect the plant's growth; once growth is affected, the plant will show an unhealthy state.

2. Solution: Water the plant properly; after watering, clear away any standing water in the flower center, and there must also be no standing water at the bottom of the pot the plant is grown in. You must also make sure the soil the plant grows in is moist and not short of water. Do all of the above, and the plant will no longer develop yellow spots.

2. Unreasonable temperature

1. Cause: When the plant grows at an unsuitable temperature, it will directly affect the plant's own functions.

2. Solution: Control the temperature of the space where the plant grows; the temperature difference must not be greater than 5 degrees. It is best to keep a constant temperature at all times, so that the plant will not develop yellow spots because of too great a temperature difference.
