Why My String of Hearts Have Yellow Leaves

Written by Ivy
If your string of hearts have yellow leaves, it may because of overwatering, drainage issues and low temperatures. Let's learn how to solve it!

Overwatering

One of the main reasons why the leaves of string of hearts turn yellow is that they are watered too frequently. Once the basin soil has too much water, the leaves of string of hearts will turn yellow and wilt, and eventually the roots and tubers will rot.

Avoid harsh sunlight

String of hearts plant likes to grow in a scattering environment, so we should avoid exposing string of hearts to the sun during maintenance, especially in summer. If we put string of hearts in the sun, its leaves will be sunburned, resulting in yellow leaves. If we accidentally sunburn, Timely transfer the string of hearts to a cool and ventilated environment.

Maintain temperature

String of hearts likes a warm growth environment. During the maintenance period, it is necessary to keep the temperature between 15 ° C and 25 ° C. string of hearts is afraid of cold, so it is best to keep the temperature above 10 ° C in winter. If the temperature is lower than 10 ° C, string of hearts will be frostbitten, resulting in yellow leaves. Therefore, the temperature in northern winter is relatively low, Keep warm in advance.

Reasonable watering

The rhizome of string of hearts has a certain water storage capacity and is very drought resistant, so it does not need to be watered frequently during the maintenance period. If excessive watering causes ponding, the root of string of hearts will rot and the leaves will become yellow due to lack of nutrient transportation. Therefore,  we need to wait until the soil is dry before watering during the maintenance of string of hearts.

Drainage issues

Many people think that the most important way to care for string of hearts is to water and fertilize these later maintenance methods, but in fact, when planting string of hearts, the configuration of basin soil is also very important. Only the soil with good air permeability and nutrition can breed strong string of hearts. But how can we ensure the drainage and ventilation of string of hearts soil? In fact, we only need to pay attention to the material of the container and the ratio of soil, so as to ensure the healthy growth of roots.

Add perlite into the potting mix 

In order to avoid water accumulation in string of hearts after watering, the poured water cannot flow directly from the drainage hole. After watering, there is no water at the bottom, or after raining, the basin soil is wet for several days and difficult to dry out, which means that the basin soil is too cohesive, too viscous, airtight and undrained, which can easily lead to string of hearts yellow leaves, We need to add character to improve the soil structure. When the soil in the string of hearts basin can not dry all the time, especially in autumn and winter, sometimes the temperature is relatively low, the light is not very strong, and the evaporation is very small, we can also place the string of hearts basin on the ground at a higher position.

Ensure your pot has drainage holes 

Potted string of hearts are basically inseparable from flowering pots. When selecting flower pots, we usually choose more appropriate flower pots according to the characteristics and size of string of hearts. For most pots, there will be holes at the bottom. Its function is to improve the drainage effect and air permeability of soil media and avoid excessive watering or blocked respiration, resulting in moldy and rotten plant roots. Therefore, we should ensure that the basin of string of hearts has drainage holes. (Also Read: How to Repot a String Of Hearts)

Use clay/terracotta pots 

Clay/terracotta pots has good air permeability to plant roots and better air permeability without glazing. The plants grown from string of hearts raised with clay / terracotta pots also grow faster, which can also prevent yellow leaves from appearing in string of hearts.

Low temperatures

String of hearts likes a warm growth environment. During the maintenance period, it is necessary to keep the temperature between 15 ° C and 25 ° C. string of hearts is afraid of cold, so it is best to keep the temperature above 10 ° C in winter. If the temperature is lower than 10 ° C, string of hearts will be frostbitten, resulting in yellow leaves. Therefore, the temperature in northern winter is relatively low, Keep warm in advance.

How to properly water a String of Hearts

1. Check the dry and wet condition of basin soil

This is extremely critical. We should check the soil every time before watering the string of hearts basin soil. Most potted plants raised indoors are usually watered after the basin soil is dry, that is to say, when the soil is dry below 3 ~ 5 cm, water it again.

2. Check the weight of the flowerpot

When maintaining small potted plants in the room, we can weigh the weight of the flowerpot and test whether the soil needs water. If the weight of the flowerpot is quite different from that before watering, we can water it in time. If the weight of the flowerpot is the same as that after watering, don't rush to water it first. You can practice more times. Basically, you can pick up the string of hearts flowerpot to know whether the plant is short of water.

3. Inspection through drain hole

We can take up the flowerpot and check whether the soil at the drain hole at the basin bottom has been dry. If the soil at the drain hole at the basin bottom is very dry, it must be watered in time.

4. Growth state of branches and leaves

If we find that the leaves of string of hearts are yellow and curly, and we don't usually water them, it must be a lack of water. This situation will lead to the yellow leaves of string of hearts and the withered plants. We can recover better by cutting off the yellow and withered leaves and maintaining a certain air humidity.
