How to Water Juniper Bonsai Plants


Bonsai is a technique for miniature plant creation that originated in China 1,200 years ago. This technique is a popular hobby using plants like trees, shrubs, herbaceous plants and succulents. The goal of bonsai is to create a dwarf plant that mimics the natural form of an old plant in the wild. Juniper plants are one of the most popular plants to use as a bonsai plant. Junipers are the easiest plants to train and care for as a bonsai.

Step 1

Fill a 2- to 3-inch deep tray with 1 inch of pebbles. Pour enough water into the tray to just reach the top of the pebbles. Place the juniper bonsai on top of the pebbles. This tray protects the surface from drainage runoff and increases the humidity around the bonsai.

Step 2

Feel the soil every day to check for dryness. Stick your finger into the soil 1/2 to 1 inch deep to see if it is dry. When the soil is dry then the juniper bonsai needs watering. During hot, dry weather, the juniper bonsai may need water every day.

Step 3

Fill the kitchen sink to the depth of the rim of the bonsai plant pot with room-temperature water. Place the juniper bonsai container in the sink. Remove enough water so the plant is only rim deep. Do not flood the top of the bonsai container since it will adversely affect the bonsai landscaping.

Step 4

Soak the juniper bonsai for 30 to 60 minutes. Allow enough time for the water to seep up through the drainage holes in the bottom. Remove the juniper bonsai from the water when the top of the soil is damp.

Step 5

Drain the juniper bonsai container for two hours before replacing the container on the tray. Do not leave the juniper bonsai standing in the water longer than 60 minutes. Over-watering causes root rot in bonsai plants.

Tips and Warnings

  • Do no let your juniper bonsai become bone dry. This creates a condition that causes the soil to repel moisture and not absorb it.
