If you want to add some beautiful vegetation to your aquarium, Dwarf Hair Grass is an excellent choice.

This type of grass is pretty easy to grow, and it will make your whole tank setup look so much nicer.

There are, however, a number of things you should know before getting started.

Types of Dwarf Hair Grass

There are three different types of Dwarf Hair Grass to choose from, so you’ll want to learn about each kind before making a final decision.

  • Eleocharis Parvula: The first type of this grass is called E. Parvula, and it is by far the most common among those who keep fish. It grows the fastest and allows for versatile placement in any tank.
  • Eleocharis acicularis: This ‘Mini” dwarf hair grass has a significantly shorter maximum length than Parvula.
  • Eleocharis Belem: This is another type of dwarf hair grass that isn’t nearly as long as the first kind, and it grows much slower.

Planting Dwarf Hair Grass

There are numerous important steps that you’ll want to follow when planting this type of hair grass. It is crucial that you follow each of these steps carefully so as to avoid any serious mistakes.

1. Dividing the Hair Grass

The first thing you need to do is to divide the grass up into numerous patches that are made up of four to six blades. You definitely want to plant it in smaller sections, as this encourages faster growth.

2. Root Trimming

A lot of people neglect the roots of these plants, which need to be trimmed. This helps the roots heal themselves much quicker than normal. By doing this you will help the grass to grow at a rapid rate.

3. Planting the Dwarf Hair Grass

Before you start planting this grass, you’ll want to get a pair of tweezers. This will allow you to put the plants in your tank with the utmost precision. The fact is that using your fingers is just too difficult in most cases.

4. Distributing the Patches

When you are distributing each patch of grass in your tank, make sure they are about half an inch apart. You don’t want them to be too close together, as this can slow down the growth process in a big way.

5. Inserting the Dwarf Hair Grass

When you insert the grass into the substrate at the bottom of your tank, do so with a great deal of care. The last thing you want is to damage any of these plants. You should keep your hand tilted at a forty five degree angle when doing this. This will allow you to get the perfect amount of leverage for planting the grass.

6. Solidify Your Plant in the Substrate

The best way to ensure that the substrate is firmly covering the roots of the plants is to shake your tweezers before pulling them out. You will only want to do this after the patch you are planting is about a third of the way into the substrate.

After You Plant the Dwarf Hair Grass

Once you are finished planting your dwarf grass, you’ll notice it start to take on a brown coloration. This is perfectly normal, so you shouldn’t be concerned. The most delicate blades of grass will start fading within the first week or two after they have been planted.

The importance of trimming your plants shortly after planting them cannot be understated. This will help them grow strong and fast, which is precisely what you want. When the blades you trim grow back, they will retain their color instead of browning.

If you are good about trimming these plants, you should notice massive growth over the following four to five weeks.

Tips for Encouraging Growth

Below we have listed some of the very best tips for encouraging growth with your new dwarf hair grass.

1. Use Proper Lighting

Dwarf hair grass is a bit more high maintenance than most other plants when it comes to lighting. You need to keep in mind that the lights you use will depend on how deep your tank is. The greater the depth, the stronger the lights must be to reach the bottom where the grass is.

Most LED aquarium lights are perfect for maintaining the growth of your dwarf grass. This is due to the high amount of photosynthetic usable radiation or PUR that these lights give off. When you take the time to choose the right lights for your tank, you’ll have no problem maintaining this grass over time.

2. Pick the Right Fertilizer

You also need to make a point of choosing the right fertilizer to grow your dwarf grass. Make sure that the one you choose is packed with macronutrients like potassium, phosphorus, and nitrogen. This will help the grass to grow strong.
