Herbs are among the plants that can be easily grown indoors or your backyard. Other than growing these in potted soil, hydroponics is a viable planting technique for regrowing herbs and making sure you never have to spend on your herbs again. Celery is a good example of an herb that can be easily grown using the Kratky Method.

 

The Kratky Method is a passive farming method that rests its foundations on the basic concepts of hydroponics. This method offers a much simpler method of growing your celery though — air pumps not required, and absolutely zero added kilo-watt-hours on your electric bill.
 

What You Will Need to Grow Celery Using Kratky Method

For the Kratky Method, you will only need the ingredients listed below. You can get all of these when you purchase a basic hydroponics kit. Or, you can always buy these separately from any  hydroponics store.


Other than the base of a store-bought celery, all you will need are:

  • (1) Empty glass jar and (1) net pot . One of the best containers to use for this method is a mason jar. Make sure to get a net pot that is as wide as your jar’s mouth. For growing celery, you may not need a container as big as a mason jar, but make sure that your bottle will be able to accommodate the radius of the base of your celery with ample space to fit your growth medium and leave some air so your herb can breathe.
Net pot and a glass jar wrapped with foil to protect the integrity of fertilizer components from degradation due to exposure to light.
  • (1) Hydroponics fertilizer.  These fertilizers usually come with proprietary combinations of nutrients intended to support the growth of your plant. Any generic fertilizer should work but, where a special nutrient combination for herbs is available, you should go for this mix. Never use plain water or you will be significantly depriving your plant with the nutrition it requires to grow.

  • (1) Growth medium. Most hydroponics growers choose rock wool and clay pebbles to use as growth medium because both provide just the right amount of moisture and drainage plants need to grow. Both growth media decrease the risks of rotting or suffocating of the roots. Either of which will work well when growing celery at home.
Most hydroponics growers prefer stone wool and clay pebbles.

 

A Step-by-Step Guide to Grow Celery Using the Kratky Method

To grow your celery, below is a list of the steps you need to follow:

Step 1: Cover your bottle with foil wrap.  The nutrients in the solution you are about to fill it with may become degraded when exposed to sunlight. You must also take note that celery loves the sun so this step is of prime importance.

Step 1: Cover your bottle in foil wrap to protect its contents.

Step 2: Follow the preparation instructions on your hydroponics fertilizer.  Any nutrient solution comes with specific instructions that you must follow down to the tee. Any more of the fertilizer than is recommended by the manufacturer may hurt your celery. Any alteration in the recommended proportion, most especially for fertilizers that require measuring and mixing, will limit the growth and yield.

Step 2: Prepare your fertilizer. Hydroponics fertilizers come with detailed instructions for use. Follow the instructions closely. Place the solution inside your bottle.

Step 3: Place your net pot inside the bottle.  Make sure that there is no chance your pot may slide inside the bottle or, your celery will drown. The water level must barely touch the bottom of the pot. As long as your growth medium touches the water, your plant should be fine. Keep in mind that your plant’s roots will  grow longer downward as the water in your jar decreases.

Step 3: Insert the net pot inside the bottle. Check that the base of the net pot just lightly touches the solution.

Step 4: Set your celery cuttings inside the net pot.  It cannot be reiterated further how important it is for the size of the container you are using to complement the size of your celery cuttings.

Step 4: Place your celery cuttings inside the net pot. Make sure that the size of the base complements the size of your bottle.

Step 5: Place your growth medium inside the net pot.  Make sure that it touches the solution and absorbs it so the solution reaches the base of your celery. Take care not to suffocate or drown your herb by putting in too much growth media or soak in too much water. Remember, you want it damp not dripping in water. Leave some space to allow air in.

Step 5: Place the growth medium inside the net pot. Surround your celery cuttings with enough growth medium.

Now, all you need to do is watch your celery grow. Every few days, make it a point to check on the level of the solution and the length of the roots. You want to make sure that the tip of the roots touches the solution and that the upper part of the root and the base of the plant are suspended in air. If the tips are not able to reach the solution, add some of your hydroponics fertilizer solution. If the top of the roots and the base of the plant are not suspended, take out some of the solution so that only the tips of the roots are submerged in the water.

 

The Best Benefits of Growing Celery

The Environmental Working Group (EWG), a non-profit that has gained worldwide recognition for its human health and environmental campaigns, includes celery in its list of produce with the highest load of pesticides for 2018. The list is based on the pesticide test results conducted by the US Department of Agriculture and Food and Drug Administration. Pesticides can cause multiple adverse effects to your health and well-being, and has been specifically demonstrated to affect the brain and nervous system. Pesticides are also known to cause infertility.

By growing your own celery, you can safeguard your health and obtain the nutrients that can be derived from this herb without the pesticides. Some of the health benefits of incorporating celery in your diet includes:

  • Anti-inflammatory and healing benefits given its high antioxidant content
  • Normal blood clotting with its Vitamin K content
  • Weight management and low cholesterol levels owing to dietary fibers
