Green radish gardenia... Will it turn into a yellow-faced woman when the weather is hot? Learn 1 move
The high temperatures in midsummer have swept over, and many flower lovers have discovered that plants such as green radish and gardenia have turned into "yellow-faced women" in their homes. Why do these common household green plants collectively turn yellow during the hot season? This article will analyze the causes of yellow leaves in 6 common plants and provide targeted greening techniques. Scientific water replenishment solution to the yellow leaf crisis first aid plan for water shortage in roses requires water replenishment once a day, and potted plants are recommended to water every other day. Special reminder: When the soil temperature exceeds 35℃, watering should be postponed, and after the ground temperature drops, choose to replenish water in the morning or evening to avoid root burns. Hydrangea water balance technique adopts the "leaf observation method": water is poured immediately when the leaves droop slightly, and a double watering system is implemented in the morning and dusk on high temperature days. Combined with a pottery basin with holes at the bottom + pine scale paving, it can effectively prevent stagnant water and root rot. The secret to water control by green radish adopts the "chopstick detection method": insert bamboo chopsticks into 2/3 of the soil in the basin, and observe the humidity after 20 minutes. If the bottom of the basin is still wet 3 cm, there is no need to water. Combined with a circulating fan to strengthen ventilation, the problem of stagnant water and yellow leaves can be quickly improved. Regulate soil acid and alkali to restore vitality.

Most gardenia yellow leaves are alkalized due to soil alkalization. It is recommended to use ferrous sulfate (1:2000) and citric acid (1 g/L) for acidification treatment every month. In the northern region, the legular soil can be replaced regularly to maintain the pH value between 5.5 and 6.5. Humidity control saves dry leaves and the humidification plan of the spider plant adopts the "double basin nesting method": the outer container is filled with 3 cm of water, and the built-in volcanic stone holds up the flowerpot to create a microclimate through water evaporation. Combined with weekly foliar spraying of beer diluent (1:50), it can enhance the water-retaining ability of leaf cuticle. Use a humidifier to maintain 60% humidity in an air-conditioned room and use a timed spray device (3 times a day, 10 seconds each time). It is recommended to use siphon self-watering flowerpots to cooperate with ceramsite paving to achieve continuous moisture retention.
Through targeted maintenance measures, most yellow leaf problems can be improved within 3-7 days. The key is to establish a maintenance closed loop of "observation-diagnosis-intervention" and regularly test the soil EC value and pH value to keep green plants green. When the new leaves are fully unfolded, seaweed fertilizer containing iron chelate can be applied to consolidate the greening effect.
