How to Grow Hydroponic Rosemary in your Garden?

If you want to plant rosemary in your kitchen or indoor garden, you need a hydroponics system. Also, you can make your own homemade DIY Hydroponics system. I share the post on how you can make your homemade hydroponics system.

How to Choosing the Right Hydroponic System

To start your hydroponic rosemary garden, it is very important to choose the right system for your garden. So that you will face no problems with your indoor garden. The two common options are:

  1. Deep Water Culture (DWC): This system contains pods or holes in hydroponic trays that suspend the rosemary plant’s roots and dip in the nutrient-rich water. It requires an air pump to supply oxygen to the roots and ensure the circulation of water without having any problems.
  2. Nutrient Film Technique (NFT): With NFT, a thin film of nutrient solution flows over the plant’s roots, providing essential nutrients. This method is suitable for smaller plants like rosemary.

What are the main factors that affect the growth of rosemary?

I will share some of my experiences which are the main issues faced by you.

Factors Affecting Rosemary GrowthDescription
Hydroponics MethodUsing the NFT (Nutrient Film Technique) system for growing rosemary hydroponically. There are many popular brands like LetPot and Click & Grow which make the best system for the users.
Growing MediumProvide a suitable medium like rock wool, porphyrite, or perlite for the plant to anchor its roots and access nutrients.
TemperatureMake sure the temperature range around the plants must be within 20°C to 25°C (68°F to 77°F). In a hydroponic system, you have the option to check the temperature.
pH RangeMonitoring and controlling the pH level of the nutrient solution within the range of 5.5 to 6.5 to ensure it’s slightly acidic, which rosemary prefers. You can use the pH device to control the pH value of the water solution.
Electrical Conductivity (EC)Keeping the EC level of the nutrient solution between 1.2-1.8 mS/cm indicates the concentration of nutrients for healthy growth.
Lighting TimeProviding 6-8 hours of light daily, either through natural sunlight or artificial grow lights, to support photosynthesis.
Germination TimeAllowing 7 to 21 days (1-3 weeks) for Hydroponic rosemary seeds to sprout and develop into seedlings.
Harvest TimeHarvesting rosemary leaves when they are ready, usually between 21 days to 42 days (4-6 weeks) after planting, depending on desired growth and flavor.

A Step-by-Step Guide to Grow Rosemary which is 100% working

1. Buy the right variety of seeds

Tuscan BlueCulinary use; strong flavor.
ArpCold-hardy; upright growth.
Spice IslandCompact; intense aroma.
ProstrateTrailing growth; ground cover.
Blue BoyCompact and ornamental.

I bought the seeds of Tuscan Blue on Amazon, it grow well. One of the reasons for growing fine, it consumes less water and is easily florished at room temperature.

You can choose any variety according to your choice and flavor.

2. Germinating Hydroponic Rosemary Seeds

It is a very important step to start your gardening in your home. To begin your hydroponic rosemary journey, you’ll need to germinate the seeds. Follow these steps to ensure successful germination:

  1. Prepare the seedling tray: Fill a seedling tray with a mixture of perlite and vermiculite for proper drainage and moisture retention.
  2. Plant the seeds: Place the rosemary seeds on top of the mixture, spacing them evenly. Lightly cover the seeds with a thin layer of the mixture.
  3. Provide warmth: Rosemary seeds require warmth to germinate. Place the seedling tray in a warm area or use a heat mat to maintain a temperature between 70-80°F (21-27°C).
  4. Maintain moisture: Keep the mixture moist but not overly wet. Mist the tray regularly and avoid overwatering, as it can lead to fungal diseases.
  5. Patience is key: Germination can take up to three weeks. Be patient and resist the temptation to disturb the seeds during this period.

I hope these steps will work for your when you start germination of rosemary seeds.

3. Put your Seeds to the Hydroponic System

Once your rosemary seeds have germinated and grown into seedlings, it’s time to transfer them to the hydroponic system. Follow these steps to ensure a smooth transition:

  1. Prepare the hydroponic system: Set up your chosen hydroponic system, ensuring it is clean and the nutrient solution is prepared according to the manufacturer’s instructions.
  2. Create small holes: Using a pencil or similar tool, create small holes in the system’s growing medium, allowing space for the rosemary seedlings.
  3. Transfer seedlings: Gently remove the seedlings from the seedling tray, being careful not to damage the delicate roots. Place each seedling in a hole, ensuring the roots are covered.
  4. Provide light and warmth: Place the hydroponic system in an area with sufficient light. Rosemary requires at least six hours of direct sunlight or the equivalent of artificial light each day. Maintain a temperature between 60-75°F (15-24°C) for optimal growth.

4. Ensure the water circulation

Make sure the water used in the hydroponics system must be fresh and within pH values 5-6 level. It is near to the balance solution which is more suitable for the rosemary plants.

You can check the pH value with the help of litmus paper or a pH test kit, also you can use the pH device to maintain the pH value within the suitable range.

5. Make sure the Lights 6-8 Hours per day

Ordinary LEDs are not working to provide enough light because they do not emit light like the sun. As we know, plants grow in sunlight, so we need specially designed LEDs that emit similar lights to the sun.

Make sure when you turn on, the temperature is not very high or low. High temperature may damage the leaves of your platns.

6. Maintaining Your Hydroponic Rosemary Garden

To ensure your hydroponic rosemary garden thrives, pay attention to the following maintenance tips:

  1. Monitor nutrient levels: Regularly check the nutrient solution levels in your hydroponic system and make adjustments as needed. Follow the manufacturer’s instructions to maintain appropriate nutrient concentrations.
  2. Prune regularly: To encourage bushier growth, prune your rosemary plants regularly. Trim off any dead or yellowing leaves and pinch back the tips of the stems.
  3. Prevent pests: Keep a close eye on your hydroponic rosemary for signs of pests such as aphids or spider mites. Use organic pest control methods or insecticidal soaps to protect your plants.
  4. Harvesting your rosemary: Once your rosemary plants reach a height of 8-12 inches (20-30 cm), you can start harvesting. Simply snip off the desired amount of rosemary sprigs, leaving enough for the plant to continue growing.


Can Rosemary Grow In Water

Yes, when we grow rosemary in a hydroponics system, we use water instead of soil. And it is better than soil plantation when w grow herbs at home.

In a hydroponics system, we can control the pH values, nutrients, and humidity around the plants. Which helps to grow rosemary well in it. Traditional water propagation methods may not yield the best results for long-term growth.

How To Grow Lots Of Rosemary

You will need a sunny spot, well-draining soil, and frequent trimming to promote bushy growth if you want to grow a lot of rosemary. Rosemary can thrive when given the right care and is highly resilient.

In a hydroponics system, we have limited pods and space. So we cannot grow herbs in large quantities.

What Is Hydroponic Farming

One technique for growing plants without soil is hydroponic farming. Rather, plants are cultivated in a nutrient-rich water solution that gives them all the building blocks they require to flourish. It’s a productive method of growing different crops in a regulated setting.

How To Keep Rosemary Plants Healthy

A rosemary plant needs well-draining soil, lots of sunshine, and frequent moisture to remain healthy. Regular pruning is going to encourage growth and guard against legginess. Avoid clear of overwatering, as this might cause root rot.

Can You Grow Herbs Hydroponically

Yes, hydroponically grown herbs are possible. Many herbs grow well in hydroponic systems, such as parsley, mint, and basil. This technique allows for the regulation of the plant’s surroundings and nutrient uptake, resulting in the growth of healthy herbs.
