3. Water the seedlings: Water the seedlings thoroughly after transplanting them into the tower, ensuring the potting mix is evenly moist.
4. Add fertilizer: Introduce a balanced fertilizer to the potting mix as per the recommended guidelines to nourish the plants and promote healthy growth.

Remember to:

• Position taller plants at the top of the tower to prevent them from blocking sunlight for lower-growing plants.
• Rotate the garden tower occasionally for even sunlight exposure and nutrient distribution, especially if the tower has a central composting axis.
• Monitor the growth of the plants and adjust their watering and fertilization needs accordingly.

By following these steps, your vertical garden tower will soon flourish with an array of healthy, productive plants.

Watering and Fertilizing

Watering Techniques

When it comes to watering a vertical garden tower, it’s important to ensure that all plants within the tower receive an adequate amount of water. There are several techniques that can be used:

• Drip Irrigation System: This method involves placing a drip line around the tower with emitters positioned to deliver water to each plant. Adjust the flow rate of the emitters to provide the appropriate amount of water to each plant.
• Manual Watering: If a drip irrigation system is not available or preferred, you can also water the tower by hand. It’s important to water each plant slowly and evenly, making sure that the water reaches the roots.
• Self-Watering System: Some tower garden designs come with a built-in self-watering system. This type of system typically uses a reservoir at the bottom of the tower, which allows water to be drawn up through capillary action or via wicking material.

Regardless of the chosen method, it’s essential to monitor the moisture levels in the growing medium to prevent over- or under-watering. Check the moisture content by feeling the soil or using a moisture meter.

Applying Fertilizer

Proper fertilization is crucial for the success of a vertical garden tower. Nutrient requirements will depend on the type of plants grown and the growing medium used. There are two common methods for applying fertilizers:
