How To Grow A Marijuana Bonsai: Step-by-Step Guide

Growing a cannabis bonsai tree is a unique and intricate process, combining the art of bonsai with cannabis cultivation. Here’s a detailed step-by-step guide to help you embark on this fascinating journey.

Step One: Selecting and Preparing the Pot

Choose the Right Pot: The pot should be shallow and wide enough to accommodate the plant’s root system while also allowing for proper drainage.

Drainage and Soil: Ensure the pot has adequate drainage holes. Fill it with a high-quality potting mix suitable for cannabis, which typically includes a blend of soil, perlite, and compost.

Step Two: Choosing and Planting Your Cutting

Selecting a Cutting: Choose a healthy cutting from a mature cannabis plant. Look for a cutting with several nodes (points where leaves emerge).

Rooting the Cutting: Plant the cutting in your prepared pot. Some growers use rooting hormones to encourage root development.

Initial Care: Keep the soil consistently moist and place the pot in a warm area with indirect light until the cutting establishes roots.

Step Three: Training Your Bonsai

Start Early: Begin training when the plant is young. This involves gently bending and shaping the trunk and branches.

Use of Wires: Carefully wrap wires around the branches and trunk to guide their growth in the desired direction. Be mindful not to damage the plant.

Regular Adjustment: Regularly adjust the wires and the direction of growth to achieve the desired shape.

Step Four: Pruning and Maintenance

Pruning: Regular pruning is necessary to maintain the shape and size of the bonsai. This includes trimming the top to control height and cutting back branches.

Leaf Trimming: Trim larger leaves to allow light to reach the lower parts of the plant, which encourages even growth.

Root Pruning: Root pruning may be required to keep the plant small and healthy. This involves gently removing the plant from the pot and trimming the roots.

Step Five: Ongoing Care

Watering: Keep the soil moist but not waterlogged. Cannabis bonsai trees require careful watering to avoid both over and under-watering.

Fertilizing: Use a balanced, gentle fertilizer to provide nutrients, especially during the growing season.

Monitoring Plant Health: Regularly check for signs of pests or diseases. Healthy bonsai cannabis plants have vibrant green leaves and a strong structure.

Step Six: Flowering and Harvesting (Optional)

If you wish to harvest from your cannabis bonsai, you will need to initiate the flowering stage by altering the light cycle (12 hours of light and 12 hours of darkness).

Once flowering is complete, you can harvest the buds. However, remember that the primary goal of a cannabis bonsai is usually ornamental.

Best Strains for Cannabis Bonsai Trees

Considerations for Choosing a Strain:

  • Growth Habit: Look for strains that naturally have a compact, bushy growth habit.
  • Response to Training: Strains that respond well to training and pruning are more suitable for bonsai.
  • Size and Height: Smaller and shorter strains are easier to manage as bonsais.
  • Flowering Time: Shorter flowering times can be advantageous if you plan to see the plant through its full life cycle.

Choosing the best strains for cannabis bonsai trees involves considering growth patterns, size, and overall manageability. Here are some strains that are particularly well-suited for bonsai cultivation:

  1. Critical Kush: This is an ideal strain for bonsai due to its robust and resilient nature. It has a sturdy structure that responds well to training and pruning, making it easier to shape.
  2. White Widow: Known for its compact growth habit, it is perfect for bonsai. Its dense and bushy structure allows for easy manipulation and maintenance, which is ideal for the bonsai technique.
  3. Northern Lights: This strain is famed for its compact, fast-growing nature. Northern Lights plants have a strong central stem and evenly spaced branches, which make them excellent candidates for bonsai training.
  4. Blueberry: This strain is appreciated for its colorful appearance and manageable size. Blueberry plants can be easily trained, and their vibrant foliage adds an aesthetic appeal to the bonsai.
  5. Sour Diesel: Although it can grow quite tall, Sour Diesel can be an excellent choice for bonsai due to its responsive nature to pruning and training. Maintaining its size requires a bit more effort but is rewarding for those looking for a challenge.
  6. Auto-flowering Strains: Auto-flowering cannabis strains like Auto Northern Lights or Auto Blueberry are great for bonsai. They naturally grow smaller and are easier to manage, making them ideal for beginners.
  7. Indica-Dominant Hybrids: Generally, Indica-dominant strains are preferred for cannabis bonsai due to their shorter and bushier growth pattern compared to Sativas.

The Best Plants to Practice Your Bonsai Craft

Practicing the art of bonsai can be a rewarding experience, and selecting the right plants is crucial for beginners and experienced enthusiasts alike. Here’s a list of some of the best plants to practice your bonsai craft, considering their ease of care, adaptability to pruning and shaping, and aesthetic appeal.

  1. Ficus (Ficus benjamina, Ficus retusa): Ficus species are among the most popular for bonsai due to their tolerance to indoor conditions, vigorous growth, and resilience to pruning. They also have attractive, glossy leaves and can develop impressive root structures.
  2. Juniper (Juniperus spp.): Junipers are classic bonsai choices, especially for outdoor gardens. They have a naturally artistic form, tolerate pruning well, and can be shaped into various styles.
  3. Chinese Elm (Ulmus parvifolia): This is an excellent choice for beginners due to its hardiness and ability to thrive indoors and outdoors. It has small leaves, ideal for bonsai, and responds well to pruning and training.
  4. Pine (Pinus spp.): Pine trees, such as the Japanese Black Pine or Scots Pine, are traditional bonsai plants. They require more skill to maintain but are highly valued for their aesthetic qualities and classic bonsai appearance.
  5. Maple (Acer spp.): Maples, particularly the Japanese Maple (Acer palmatum), are famous for their vibrant fall colors and delicate leaves. They are a bit more sensitive but offer stunning visual appeal.

Tips for Successful Bonsai Training:

Start Slow: Begin with easier techniques like pruning and work up to more advanced techniques like wiring.

Understand Your Tree: Different species respond differently to training techniques. Research your bonsai species to understand its specific needs.

Be Patient and Observant: Bonsai training is a slow process. Regularly observe your tree’s response to training.

Use the Right Tools: Invest in good quality bonsai tools for precision and ease.

Remember, the key to successful bonsai training is a combination of patience, observation, and adapting your techniques to the response of the tree. Each tree is unique, and part of the joy of bonsai is learning to work with its individual characteristics.

Cultivating a cannabis bonsai tree is a rewarding endeavor that blends horticultural skill with artistic expression. It’s a unique way to grow cannabis while enjoying the beauty of bonsai. Recognize the journey is as important as the destination in the art of bonsai.


Can I use LED lights for growing a cannabis bonsai indoors?

LED lights are suitable for growing cannabis bonsai indoors. They provide the necessary light spectrum, are energy-efficient, and produce less heat than traditional grow lights.

How often should I water my cannabis bonsai?

Watering frequency depends on several factors, such as the size of the pot, the type of soil, and the environment. Generally, water when the top inch of the soil feels dry. Over-watering can be as harmful as under-watering.

Is it necessary to use fertilizers for my bonsai, and what kind should I use?

Fertilizers are essential for the health and growth of your bonsai. Use a balanced, water-soluble fertilizer during the growing season, reducing frequency in winter. Organic options like fish emulsion are also beneficial.

How long does it take to train a cannabis bonsai tree?

Training a cannabis bonsai tree can take several months to years, depending on the desired size and shape. Patience is key, as bonsai is a gradual art form.

What is the ideal temperature and humidity for a cannabis bonsai?

Cannabis bonsai thrive in temperatures between 65-80°F (18-27°C). Humidity levels should be around 40-60%. However, lower humidity (around 40%) is preferable to prevent mold during the flowering phase.

Can I create a bonsai from any cannabis plant, or are there specific types?

While you can attempt bonsai with most cannabis plants, compact and bushy varieties are more manageable. Auto-flowering strains are particularly suitable for beginners due to their smaller size and shorter life cycle.
