Do I need to water the plants every day in summer?
Plant maintenance in midsummer faces severe challenges, and watering management is directly related to the survival status of plants. This article deeply analyzes the scientific methods of watering in summer, and formulates precise maintenance plans based on different plant characteristics to help you create a green courtyard landscape. 1. Analysis of differences in plant water requirements 1.1 Key points for the maintenance of hygrophilic plants Typical hygrophilic plants such as gardenia and rose still maintain growth vitality during high temperatures above 30℃, and the soil needs to be kept continuously moist. Detection method by inserting bamboo stick: Insert the bamboo stick into 2/3 of the basin soil. If no soil adheres to it when it is pulled out, water should be replenished immediately. 1.2 Water control strategies for drought-tolerant plants. Succulent root plants such as Changshou flower and Clivia enter a semi-dormant state in summer and need to adopt the principle of "dry through irrigation through". Judging by the weight of the pot soil: When the weight of the pot is reduced to 2/3 of that of the normal watering state, slowly inject clean water at room temperature along the edge of the pot. 2. Regional climate watering plan 2.1 Meiyu areas such as the Yangtze River Basin in the hot and humid regions of the south need to be equipped with drainage substrates, using a ratio of perlite + legular soil (3:7). Observe the leaf surface condition every evening on sunny days, and add spray when slight wilting occurs. 2.2 The North China Plain, a dry area in the north, recommends using the dipping basin method: place the flower pot in a water basin twice a week and soak it for 15 minutes, and combine it with morning and evening leaf spray to maintain the air humidity at 60%-70%. 3. Professional maintenance skills 3.1 The best watering time for selecting time periods is before sunrise (5-7 o'clock) or after sunset (19-21 o'clock). The temperature difference between soil temperature and water temperature during this period is ≤3℃ to avoid root heat stress reactions. 3.2 Water quality treatment process Tap water needs to be left standing for 48 hours to remove chlorine, or 0.1% citric acid is added to adjust the pH value to 6.0-6.5. Rainwater can be collected during the rainy season, and its nitrogen content can reach 0.2mg/L to promote plant growth.
Scientific watering needs to be considered in three dimensions: plant characteristics, regional climate, and seasonal changes. It is recommended to establish a maintenance log to record each watering time, amount of water and plant reaction, and gradually form a personalized irrigation plan so that each plant can spend the summer safely.
