Growing Brassica Vegetables on a Tower Garden: A Guide to Success

Brassica vegetables, including broccoli, cabbage, kale, and cauliflower, are not only delicious but also packed with essential nutrients. Imagine having these nutritious greens readily available in your own backyard, thanks to the convenience of a Tower Garden. In this guide, we’ll explore the steps to successfully grow Brassica vegetables on your Tower Garden, ensuring a bountiful harvest and a healthier lifestyle.

Choosing the Right Varieties:

Before diving into the growing process, it’s essential to select Brassica vegetable varieties that are well-suited for vertical gardening. Opt for compact or dwarf varieties that thrive in smaller spaces and have shorter growing seasons. Some excellent choices include:

  • Broccoli: Consider varieties like ‘De Cicco’ or ‘Calabrese’ for their compact growth habit and abundant side shoots.
  • Kale: ‘Dwarf Blue Curled’ and ‘Red Russian’ are excellent choices for Tower Gardens, offering tender leaves and vibrant colors.
  • Cabbage: Look for compact cabbage varieties such as ‘Gonzales’ or ‘Mini Dynasty’ that produce small heads ideal for vertical growing.
  • Cauliflower: ‘All The Year Round’ and ‘Snowball’ are compact cauliflower varieties that adapt well to Tower Gardens.

Preparing the Tower Garden:

Ensure your Tower Garden is set up and ready for planting. Follow the manufacturer’s instructions for assembly and installation, making sure the reservoir is filled with water and the pH level is adjusted to the recommended range for Brassica vegetables (typically between 6.0 and 7.0).

Planting Brassica Seedlings:

Start by germinating Brassica seeds indoors or purchase seedlings from a reputable nursery. Once the seedlings have developed a few true leaves, transplant them into your Tower Garden’s growing ports. Space the seedlings according to the plant’s mature size, ensuring adequate airflow and sunlight penetration.

Providing Optimal Conditions:

Brassica vegetables thrive in cool weather and full sun, so place your Tower Garden in a location that receives at least 6-8 hours of sunlight per day. Monitor temperature levels to ensure they remain within the ideal range for Brassica growth (around 60-75°F or 15-24°C).

Watering and Nutrient Management:

Maintain consistent moisture levels in the Tower Garden’s reservoir to ensure the roots have access to water and nutrients. Brassica vegetables are heavy feeders, so supplement with a balanced hydroponic fertilizer rich in nitrogen, phosphorus, and potassium. Monitor the nutrient levels regularly and adjust as needed to support healthy growth.

Pest and Disease Management:

Keep an eye out for common Brassica pests such as aphids, cabbage worms, and flea beetles, especially during the growing season. Implement organic pest control methods such as companion planting, row covers, or introducing beneficial insects to keep pests at bay. Additionally, practice good sanitation to prevent the spread of diseases and pathogens.

Harvesting Brassica Vegetables:

Brassica vegetables are typically ready for harvest within 60-90 days, depending on the variety and growing conditions. Harvest broccoli and cauliflower when the heads are firm and compact, and cabbage when the heads are firm and fully formed. For kale, harvest individual leaves as needed, allowing the plant to continue producing throughout the season.


Growing Brassica vegetables on a Tower Garden is not only convenient but also incredibly rewarding. With proper care and attention to detail, you can enjoy a continuous supply of fresh, nutritious greens right at your fingertips. Follow the guidelines outlined in this guide, and embark on a journey to a healthier, more sustainable lifestyle through vertical gardening.
