Daun Haus

This is the story :)

Selasa sore, saat Mba upi (asistenbya Uti) sedang menyirm pohon :

Azka (A) : Mba Pi, agi apah?
Mba Upi (U) : Lagi siramin pohon
A : mang, daunnya haus ya?
U : ha..ha.. (ketawa geli) Iya, pohonnya haus, jadi disiram, biar minum.

Kayanya Azka perlu penjelasan lebih banyak nih. Malemnya, Bunda review.

Intinya, Bunda jelaskan, kalau pohon itu juga makhluk hidup, daun pun bisa haus dan butuh minum. Minum juga bisa menjadikan daun bertambah besar atau tumbuh. (ehm... bunda need more reading nreferencies).

Dan tanggapan Azka.... no comment. teruas mimik ASI sambil lihat wajah Bunda.

Dan siang ini, Bunda browsing, mendapatkan jawaban yang bisa memuaskan Azka...

Ini copy artikelnya ya...

Why Do Plants Need to Be Watered?

1. When you pour water onto a thirsty plant, several beneficial things happen. The soil becomes wet, which dissolves minerals that the plant needs for nutrition so its roots are able to absorb them. After the roots begin taking in the water, the fluid acts as a transportation medium to carry moisture through the entire plant. The process is similar to the way water in your body transports nutrients and waste. The water keeps the proper pressure in plant cells through a process called turgidity. Water also combines with carbon molecules for photosynthesis, which is the process that forms food for plants and also what causes them to release the oxygen you breathe as a waste product.
   
   Plants store water in their roots and depend on evaporation to keep the leaves cool. If the water supply to a leaf or stem is cut off, that part of the plant turns yellow, orange, red or brown and eventually dies. Water's absence signals the leaves to die off, which is responsible for fall foliage present in many parts of the United States in September through November.
   

   Watering Houseplants

2. According to Plant-Care.com, the amount of water houseplants require depends on multiple factors, such as the size of the leaves, the composition of the soil, and heat and humidity levels in the air. Be careful not to overwater houseplants, as it can cause them to die. To check the water level, place your finger into the soil near the plant. If it feels moist, then the plant has too much water; if it feels dry, the plant has too little. Saturate the soil to a depth of at least 8 inches for established plants when watering. This will encourage the plant's roots to reach down where water is more likely to be stored for longer periods of time.
   

   Water Types

3. You should be able to use any type of water, but some types make for stronger plants. According to Home Harvest Garden Supply, most houseplants prefer water with an acidic pH level--between 5.0 and 6.5, but some foliage prefers a slightly more alkaline mixture. You can add pH drops or use test strips to determine your water's pH. Because the water is broken down into the soil quickly and mixes with minerals, the pH of the water may change after it is added. You should not water plants with water that has passed through a softening filtration system unless it has been deionized to reduce salt content.
