Purple Fountain Grass is a stunning ornamental plant with burgundy or purple leaves, making this plant stand out wherever it is kept. Many people love this plant as it is a low-maintenance plant. This plant can be easily grown and kept in a pot or container for its whole life. 

To grow Purple Fountain Grass organically from seeds, you first need to make sure the seeds are dried, as this will help you break open the seed capsule if you have picked the seeds yourself. If you brought the seeds from a shop, then you can just start planting. 

It is best to start your Purple Fountain Grass off indoors so you can monitor the plant environment, and it is best to start planting these seeds in the early spring. So let us go through the steps to grow your Purple Fountain Grass from seeds:

  • Get a pot or container ready with an organic potting soil mixture that has perlite or peat moss in it as this plant needs well-draining soil
  • Dig small ½ inch (1cm) holes into the soil about two inches (5cm) apart from each other
  • Carefully place one seed in each hole and cover the seed with soil 
  • Gently water the planted seeds just until the soil is damp, do not overwater
  • Place the pot in a warm location with bright light; it can be placed in partial shade if needed
  • Keep the soil moist, and the plants should begin to sprout in about 21 days

Once the seeds have grown two leaves, you can transplant them into individual containers/pots or your garden. Ensure all the pots or containers you use have good drainage. 

How Often Should Purple Fountain Grass Be Watered/Trimmed? 

Purple Fountain Grass is a drought-tolerant plant that can handle some stress or “loving neglect.” This does mean that the plant enjoys having its soil more on the drier side. So, you need to wait for the soil to dry before you water your Purple Fountain Grass again.

But then, when you do water your Purple Fountain Grass, you need to water it well until the soil is moist all the way through the pot/container but be sure not to overwater it as it is prone to root rot. 

The amount of time between watering will be determined by the temperature you keep your Purple Fountain Grass in. The hotter the temperature, the more often the plant will need to be watered. You will need to come up with a watering schedule that matches your plant’s living conditions. 

Purple Fountain Plants do not need to be trimmed regularly, but if you find any dead, dying, diseased or yellow leaves on the plant, it will benefit the plant’s health if you trimmed these off. Ensure you trim these leaves from the base using sharp shears or scissors.

Purple Fountain grass is a fast-growing plant that can easily grow between 3 to 5 feet (90 to 150cm) tall and about 2 to 4 feet (60 to 120cm) wide when fully mature. This means that you need to choose a planting pot or container that can sustain this plant’s fast growth. 

The best size pot or container to use for your Purple Fountain Grass is one that can house the plant for at least two years before needing to be changed. To ensure your pot or container is big enough for this, you need a container that is bigger than your plant’s root ball by 8 inches (20cm) or more in width from the edge of the pot to the plant when the plant is in the middle of the pot. 

As your Purple Fountain Grass grows, your will need to adjust the pot or container you keep it in to ensure the plant stays healthy. 

When To Repot Your Purple Fountain Grass

Your Purple Fountain Grass will eventually outgrow the pot or container it is in, especially if it stays in the same pot for a few years. There are methods you can use to tell if it is time to repot your Purple Fountain Grass yet or not. 

If you pick up the pot/container and you can see the roots of your Purple Fountain Grass growing through the pot’s drainage holes, then you need to repot your plant. If your Purple Fountain Grass has roots that are beginning to show above the soil in the pot/container, then you should repot your plant as soon as you can. 

If there are more of the plant’s roots in the pot than soil in your Purple Fountain Grass plant’s pot/container, then this is an urgent matter, and your plant needs to be repotted immediately as Purple Fountain Grass does not like to be root bound at all, and this can cause problems with the plant’s health.
