Sampaguita is a beautiful flower that has a fragrant smell. Many gardeners grow this flower in their garden but it will be difficult to care especially when there are many yellow leaves growing on the plant. The plant must avoid getting lots of yellow leaves so that it can produce more flowers. But what are the reasons why sampaguita leaves are yellowing?
Sampaguita Leaves Turning Yellow
Watering Problems
Overwatering
Overwatering can cause yellow leaves on the sampaguita. The sampaguita cannot handle too much water and it causes stress. Overwatering can happen when too much water is given to the sampaguita or it can happen when heavy rains come.
A watering can or a garden hose can be used to water your sampaguita but just give the right amount of water. Check the soil moisture before watering the sampaguita if the soil is dry you can water it but if the soil is moist you don’t need to.
There are ways to check the soil moisture like pressing your finger a few centimeters in the soil, pressing a screwdriver, or using a soil moisture meter. Any of those ways can be used to know the soil moisture and gives you an idea of when to water the sampaguita.
A well-draining soil is also helpful to avoid waterlogging. Sometimes heavy rainfall comes to your location and you must make good waterways to prevent your sampaguita from getting flooded. Too much water can cause root rot which makes leaves yellow but when it’s prevented the leaves are safe.
Lacking Water
Lacking water can also cause yellow leaves on the sampaguita. Water is essential for the sampaguita to grow well which helps it to grow healthy and able to produce more fruits. Water the sampaguita regularly and make a watering schedule so that you know when to water your plant.
The sampaguita needs more water when the weather becomes hot. With the right amount of water, it can make the plant cool and hydrated. The sampaguita needs at least 1 inch of water per week.
Aging Sampaguita Leaves
It is normal to see yellow leaves on any plant or tree. Commonly these yellow leaves are aging leaves. It is normal to see these kinds of leaves even on sampaguita because it is part of their growth.
It is a cycle for the sampaguita leaves to grow and then get old. The young leaves will grow and after a few weeks or months, they turn yellow, and eventually, sampaguita leaves turn brown.
If there are only a few yellow leaves on the sampaguita then probably they are just aging leaves but if there are too many yellow leaves you need to analyze and observe if there are other reasons causing the problem.
Nutrient Deficiencies
Nitrogen is an important nutrient needed by the sampaguita to keep its leaves growing and staying green. Nitrogen deficiency causes yellow leaves on the sampaguita and to prevent it from happening you need to make the soil rich in nitrogen. You can use a soil tester to check the soil and then apply the right amount of nitrogen.
The sampaguita needs nitrogen because this nutrient helps the production of chlorophyll in the leaves. Chlorophyll helps the sampaguita to convert sunlight into food which makes helps it grow better. Aside from nitrogen, Iron deficiency can also cause leaves to turn yellow on sampaguita.
There are many kinds of fertilizer and some of them have nitrogen and iron along with other nutrients which are helpful for the sampaguita to grow well if applied.
Transplant Shock
Moving your sampaguita to a new location can cause transplant shock. Transplant shock causes stress which can lead the leaves to turn yellow. Shock commonly affects mature sampaguita and not that young sampaguita.
You need to be careful in transferring mature sampaguita because transplant shock may happen. Water the sampaguita immediately just after transplanting. You will need to wait for a few days or weeks and monitor how the sampaguita goes especially when they suffer transplant shock.
Usually, those young sampaguita don’t get transplant shock. They just need to be watered after transplanting and they will grow just fine.
You Overfertilized Sampaguita
You also need to be careful not to overfertilize sampaguita. Too much fertilizer can burn roots and when roots get damaged it can cause yellow leaves. When roots are damaged the sampaguita cannot get enough water and nutrients because the roots are not functioning well.
Avoid overfertilizing sampaguita especially if you are using chemical fertilizers because they can burn sampaguita roots.
If you are practicing organic gardening then you can use compost and other organic fertilizers. You can also add mulch to keep soil moisture.
Sampaguita Is Lacking Sunlight
The sampaguita needs sunlight to grow healthy and be able to produce more food. Grow the sampaguita in a place where it can get a lot of sunlight so that the yellowing of leaves can be prevented. The sampaguita needs at least 6 hours of sunlight per day.
Avoid growing the sampaguita near tall trees because it may not get enough sunlight because those tall trees may block the sunlight. When the sampaguita is getting consistent sunlight per day it will grow healthy and can give you a lot of fruits.
Weather Changes
Weather changes can also affect the sampaguita which may lead to its leaves turning yellow. Even if the sampaguita needs more sunlight, extreme heat is not good. Too much sunlight can affect the leaves which can make them yellow. Keep the plants hydrated when the weather becomes hot.
Pests And Diseases
There are pests and diseases that may also cause yellow leaves on your sampaguita. You need to monitor your sampaguita and see if there are pests and diseases that attack your sampaguita. In that way, you can protect them and you can use pesticides or fungicides to get rid of them.
