Porcupine Grass Seeds
The seeds are very small and hard to see. They have a greenish color.
There are different kinds of porcupine grass seeds. Some varieties produce only one kind of seed while others can produce several types of seeds. These varieties usually come from the same species but there is no guarantee that they will all produce the same variety of seed or even the same type at all!
If you want to plant your own seeds, it’s best if you start with a good quality seed packet. You don’t need to buy any expensive seeds because most garden centers sell them.
If you’re not sure what kind of seed to get, look around the store for “porcupine grass” or some other common name. Most stores carry both white and red varieties. White porcupine grass is probably the easiest to recognize since it’s the most commonly sold variety. Red varieties are harder to find so you may have to go out of your way to find them.
Planting Your Own Seeds
You’ll need a container big enough for planting your seeds. A large pot works well because it makes planting easier and less likely that the soil will dry up before germination occurs.
If you want fast results, go with at least a five gallon pot. Otherwise, a three or four gallon container will do.
If you’re planting the seeds outdoors, go with a one to three gallon size. It’ll take longer for them to germinate but the container will be much easier to handle when it’s time to plant them in the ground.
You don’t need any special soil for porcupine grass. A good quality potting soil is fine.
However, it’s best if you can find a soil that does not contain any fertilizer. Fertilizer can burn the seeds and prevent them from germinating.
Porcupine grass seeds need sunlight to grow. If you’re planting them outdoors, make sure you choose a spot that gets at least four hours of direct sunlight daily.
You can plant them outdoors as soon as you have prepared your pot.
Planting Your Seeds
Fill your container with soil. Leave a one to two inch gap at the top to make room for the seeds.
If you’re planting several types of seeds, make sure you leave enough room in the container for all of them. Spread your seeds out in a single layer across the top of the soil. This will help them receive the sunlight they need. You don’t have to cover them with soil. If you do cover them, be sure to only use a very thin layer of soil (a quarter inch or less). This is important because the seeds need to remain exposed to the sun.
Keep the container moist but not wet. Water the container from underneath (i.e.
put it in a bowl of water) to ensure it stays moist but not soaked. You can add water as needed. If the seeds get too wet you may have to drain some of the water out. Too much water can cause the seeds to rot.
Leave the container in a place that gets direct sunlight for several hours daily. Porcupine grass seeds need sunlight to sprout so make sure you don’t put it in a spot where it will be in the shadows most of the day.
Check on your seeds daily to see if they have sprouted.
Planting Your Seeds Outdoors
Outdoor planting is best done during the spring and summer so that your seedlings have time to grow before the first frost arrives.
When you’re ready to plant, choose a sunny spot in your yard that has loose, well drained soil. If your soil is heavy and wet, you may want to add more sand or gravel to it before planting.
Loosen the soil using a digging bar to create a hole big enough for the container. If the sides of the hole are sloping, use a rake to make them level.
Using a watering can or hose, gently pour water into the hole. Fill it until you have wet all the soil and there is a small puddle at the bottom of the hole.
Gently remove your container from its pot and tilt it over the planting hole. The seeds should slide right out into the soil.
If not, use a spoon to scoop them out.
Add a small amount of soil to the hole. Level it out using a rake and then add more soil until the hole is filled and the soil is level with the rest of your yard.
Use a hose or watering can to gently add water to the soil until it’s moist throughout. Small cracks and crevasses may appear but that’s okay, they will disappear when the soil is dry again.
