Benefits of Growing Aquaponic Flowers

Benefits of Growing Aquaponic Flowers

There are many reasons to love flowers. Growing them can be therapeutic, especially when the mix of vibrant colors populate your garden. Aesthetics may be one of the more common reasons to plant flowers, but more than that, they can contribute much to your garden in the following ways:

  • Culinary Applications
  • Pest Management
  • Invites Pollinators
  • Cut-Flower Business

Culinary Applications

Many flowers are edible. Some are used as a garnish to increase a dish’s palatability while others are included in the recipe itself, bringing in unique flavors to your meal. When you plan to grow flowers for culinary purposes, always check that the species you have in mind is edible. When in doubt, skip it.

Pest Management

Aquaponics is known for the fact that it doesn’t use chemicals to deal with pest problems. A common solution to pests is employing natural pest control methods – one of which is companion planting. Some flower species act as sacrificial plants, which attract pests instead of having them proliferate in your main crops. 

On the other hand, there are flowers that are, by nature, repellents because of their intense aroma. Examples of these are lavender and marigolds.

Invites Pollinators

Having flowers in your garden attracts beneficial insects such as bees and butterflies, which are also hard workers at pollination. Pollinator insects (sometimes birds) can help flowers set, so they form into a fruit. That being said, inviting them will help if you are growing plants that need pollination, such as okra, cauliflower, and cucumbers, just to name a few.

Cut-Flower Business

One way to use aquaponics commercially is to grow flowers for a cut flower business. If you love the idea of supplying homemade bouquets for special occasions, then a cut flower business may be right for you. You can take it up a notch by using sustainable practices – which is growing them in an aquaponics setup.

Best Flowers To Grow In Your Aquaponics Garden

There are many kinds of flowers you can plant in your aquaponics garden. Below are our top 5 best flowers for aquaponics based on their ease of maintenance and versatility.

1) Marigolds

Marigolds in aquaponics systems

If you love blooms all summer, Marigold is one of the easiest and most cheerful flowering plants to keep. Not only do they provide wonderful shades of yellow and orange flowers, but they are known to be excellent companion plants in the garden.

Marigolds can attract beneficial insects and help eliminate unwanted pests from your garden. Since aquaponics mostly uses natural pest control methods, companion planting with marigolds does the job of keeping pests at bay.

Quick Marigold Planting Tips

Marigolds are just like most plants – they love full sun. Place your marigolds where they receive six hours of sun a day. You can encourage bushy growth by pinching off the top leaves of established marigolds. You can enjoy marigold blooms when using either media grow beds or nutrient film technique (NFT).

2) Roses

Roses are easily among the well-loved plants. They smell fantastic, and they can transform a garden, soilless, or otherwise. Having them also means you get to have cut-flowers you can give away as a gift or sell for special occasions.

You can grow a variety of roses as they come in different colors, sizes, and growing habits. When growing roses aquaponically, most people use propagated cuttings instead of seeds as the latter can take longer to grow.

Quick Rose Planting Tips

NFT is the most common aquaponics method for rose production, but grow beds can also be great. You can set up your NFT system from scratch by looking for the right pipe size, or you can purchase a pre-made one, such as this GOWE NFT system. 

Place your roses in a location that receives full sun. Prune established bushes to encourage the growth of more blooms. Pests to watch out for when growing roses include black spot and powdery mildew.

3) Nasturtium

Nasturtium in aquaponics systems

Nasturtiums not only bear flowers that can add beauty to your surroundings, but they are excellent at deterring garden pests. More importantly, nasturtium flowers and leaves are edible. The plant can be your culinary friend; flowers are used as a garnish while leaves are used like pepper to add some kick to your meals.

Growing this all-purpose plant is relatively easy, especially in an aquaponics setup. They are excellent as trap crops, which are sacrificial plants that attract pests and lure them away from your main crops. For example, when planted together with cabbages, the nasturtiums can attract aphids, thereby saving your cabbages from a possible infestation.

At the same time, nasturtiums can help repel pests such as squash bugs and cucumber beetles, thereby making them excellent companion plants for cucumbers and tomatoes.

Quick Nasturtium Planting Tips

Nasturtiums are fairly quick to grow. If you’re starting with seeds, you can expect germination to take place within 7-10 days. They love the light, but they would best thrive in an environment with low heat stress.

4) Pansies

Pansies in aquaponics systems

Pansies are among the edible flowers you don’t want to miss planting in your aquaponics garden. Plus, they are an excellent flowering plant for beginners, since they are not fussy and can have a long flowering season despite given minimum care. In the kitchen, pansies can be your source of minty flavor, which you can use to garnish salads and desserts.

One interesting fact about pansies is that they are rich in an antioxidant compound called rutin, which is found to strengthen blood vessels, consequently improving overall health and ease conditions such as varicose veins. 

Quick Pansy Planting Tips

Pansies enjoy the full or partial sun, but they tend to thrive in cooler temperatures. Ideally, they should be exposed to the morning sun but kept away from the stress of the afternoon heat. To encourage pansies to produce more flowers and prolong the blooming season, you should remove dead flowers.

Quick Sunflower Planting Tips
