How to turn yellow leaves of flowers green?

With the improvement of living standards, more and more people are growing flowers. Keeping some flowers and plants at home can not only add greenery and beautify the home, but also purify the air and increase the oxygen content in the air. At the same time, many plants have beautiful meanings. However, when raising flowers and plants, people will find that the leaves turn yellow. So how can we turn the yellow leaves of flowers green? Let’s take a look below.

1. How to turn yellow leaves of flowers green?

1. Ferrous sulfate

Most flowers like acid, and it is easy for them to have yellow leaves and falling buds. Ferrous sulfate can turn the soil into acidic soil, which is an indispensable chemical adjuster for growing flowers in the north. When the leaves of your flowers begin to turn yellow, especially when the new leaves are light yellow instead of green, you should start supplementing them with ferrous sulfate.

How to use: Buy some ferrous sulfate, add it to cold water at a ratio of 1:1000, and water it once every 20 days. You can also spray it on the leaves and stems of flowers to accelerate absorption. The mixed solution must be used up at one time, otherwise it will oxidize if left for a long time.

Suitable for flowers:

Gardenia, jasmine, rose, bougainvillea, azalea, camellia, sasanqua, orchid, white orchid, hydrangea, etc.

2. Citric acid

If you can't buy ferrous sulfate, you can use citric acid instead. Citric acid is also a chemical agent. It is sold in some supermarkets and pharmacies. It is used to clean kitchen dirt. Citric acid is also a food raw material. It is also convenient to make your own citric acid. Take 10 ml of white vinegar, half a slice of fresh lemon, and 1 liter of cold water. Mix the three and soak them for 12 hours to make citric acid.

Directions:

Mix citric acid powder with cold water at a ratio of 1:1000 and water the flowers 1-2 times a month. If it is homemade citric acid water, you can take out 10 ml, dilute it in 1 liter of clean water, and water the flowers. Water it once every 10 days or so.

Suitable for flowers:

Like ferrous sulfate, citric acid is suitable for plants that are prone to yellowing leaves, such as gardenia, jasmine, rose, bougainvillea, azalea, camellia, sasanqua, orchid, white orchid, hydrangea, lucky tree, and money tree (watering once a month is enough).

3. Banana peel water

If the leaves of the flowers start to turn yellow from the edges, it is most likely due to a lack of potassium. In addition to supplementing with compound fertilizer (nitrogen, phosphorus and potassium), you can also make some banana water to quickly replenish potassium.

Directions:

Soak banana peels (freshly peeled, ripe and spotted are best) directly in clean water, seal and ferment for 5-7 days, filter out the clean water and use it to water the flowers. It can be watered 1-3 times a month, and the leaves can be wiped with banana peels.

Suitable for flowers:

Pothos, lucky bamboo, money tree, rose, hydrangea, chrysanthemum, golden diamond, rubber tree, dragon blood tree, Clivia, gardenia, evergreen, pennywort , spider plant, dieffenbachia , arrowroot, strawberry, eggplant, pepper, etc.

4. Urea

If the flower's old leaves turn yellow and the new leaves turn dull, it means that it is lacking nitrogen fertilizer. At this time, you must quickly replenish the fertilizer, otherwise the growth will stop and there will be a risk of death.

Directions:

Urea is very strong for home potted flowers and must be used with caution. For example, 1-2 grains of urea are enough for 1 liter of water, and it should be watered once a month. Too much water may easily burn the roots. If it is outdoor farming or growing fruits and vegetables, you can add more.

Suitable for flowers:

Bougainvillea, rose, Milan, Schefflera, gardenia, camellia, lemon, passion fruit, fig, grapes, and various vegetables and fruits.

2. Things to note when the leaves of flowers turn yellow

1. Do not overwater

If we cannot control our hands when growing flowers and water them all the time or frequently, the amount of water required by potted flowers indoors or on the balcony is not large. Or when the temperature is not high and the ventilation is poor, if you keep watering, the soil in the pot will become moist and waterlogged, which can easily cause the leaves to turn yellow, black, fall off, etc., so watering must be controlled well.

2. Cannot lack light for a long time

When growing flowers, potted flowers and plants basically need sunlight. Even shade-loving plants such as green ivy, spider plants, Clivia, ferns, and ivy cannot be kept in a place without any light all year round. It needs a certain amount of diffuse light. If it is placed in a hidden environment for a long time, the leaves will not get enough sunlight, which will also cause yellowing. Because chlorophyll cannot be formed, the leaves of the plant turn yellow and fall off. In this case, the plant should be placed in a sunny place in time.

3. Too little watering

When we are growing flowers, we find that the tips of the leaves or the edges of the leaves are turning yellow, or the old leaves are turning yellow and falling from the bottom to the top, but the new leaves are normal. This means that the yellow leaves are caused by drought. The plant lacks water, which leads to the yellow leaves. At this time, just water it enough.

4. Yellow leaves caused by improper fertilization

If too much fertilizer is applied, or the fertilizer is too concentrated, too much fertilizer is applied at one time, or the number of fertilizations is too many, the plant cannot bear it and the new leaves will appear dry and brown. The leaves have lost their luster and old leaves have begun to fall off, so fertilizing should be stopped. If no fertilizer is applied for a long time and there is a lack of fertilizer, the young leaves will turn from green to light green or even yellow. At this time, pay attention to adding fertilizer and nutrients. As long as you apply thin fertilizer frequently, it will start to turn green again.
