If you are interested in growing beardtongue flowers in your garden, the best way to grow them is by starting the plants from seed. The seeds can be purchased online or in some specialty gardening stores.

The best time of year to start seedlings is early spring. Prepare your soil by mixing in some organic matter like peat moss, compost or rotted manure.

Add a general purpose fertilizer at the rate recommended on the package and mix everything together. You want the soil to be loose and fertile without being packed down or too heavy.

Thin out your seedlings so there is about an inch of soil between each seedling. They can be planted outside after all danger of a frost has passed.

Set them out in an area that gets at least six to eight hours of full sunlight a day and water them daily or whenever the soil feels dry.

Once the plants are a few inches tall, you can thin them out so they are about 8 to 10 inches apart. Deadhead the flowers once they fade and when the weather gets too hot, your beardtongue plants should be able to handle the heat and humidity of summer just fine.

Good penstemon flowers can also be purchased online and at some garden centers. They can be planted in spring or fall, but a well-maintained garden can have flowers blooming from early spring all the way into fall.

Unattractive or invasive weeds can easily be pulled from the garden. If your soil is dry, you can water the beardtongue plants daily or every other day.

If it does not rain for a week, give the plants a deep watering once a week.

You can divide the plants every few years to promote new growth and to get more flowers. This is best done in spring just as the plants begin to bloom.

Using a sharp spade, cut the plant about an inch below the surface of the soil and gently lift it out of the ground. Separate the divisions and replant them in an empty area of your garden.

The best way to keep your garden looking great is to limit the number of visitors. Unless you live on acreage, your neighbors may not be too happy if your yard is overflowing into the alley.

If they ask you to keep your plants contained, then respect their wishes.

If you have no intention of limiting your flower garden on purpose, you can still enforce some limits by keeping the inside of the bed neat and orderly.
