How to create a Rockery (Rock Garden)

So… What is a Rockery?

Simply put, a rockery is a rock garden.

Rockeries are often human-made, but some can be naturally occurring. They present a challenge to gardeners both new and experienced. They require different care than other types of gardens. But once you figure it out, you will be greatly rewarded.

A rockery is a statement piece and will attract the attention and appreciation of visitors, neighbors, and other onlookers.

Where Should I Build a Rockery?

Rockeries naturally occur on slopes or hillsides. If you have a slope you're not sure what to do with, think about turning into a rockery.

If there is a spot in your garden that has soil that is difficult to work with, you could turn that area into a rockery. Places that receive ice-treatment salt like at the side of a driveway or by the mailbox are ideal locations.

A rockery can be created anywhere you would like. If it fits your garden design or you want a change, a rockery is a great way to create visual interest.

Materials Needed:

To build a rockery you will need rocks-- surprising right? You can acquire a few of the materials on this list or everything; it depends on your design scale. Here are some items you may need:

  • Boulders if you have them or want them in your garden
  • Large, medium, and small rocks (locally sourced is ideal)
  • Gravel, shale, pebbles, or grit
  • Rubble (broken bricks and concrete)
  • Topsoil and/or compost
  • Mulch

How to Build a Rockery:

Creeping phlox has a low-growing habit. It's flowers are tiny and they hide its foiage

Don't let this process daunt you, it can be done over a few days or weeks or even months. You can play around with the size and scale of your rockery.

If you have lots of space and plenty of rocks, you can make a large rockery. You can also make a rockery that's the diameter of a hula hoop.

No mater the size of your rockery, the same basic building principals apply:

  1. Create a gentle mound with rocks and dirt. Rocks occur naturally on slopes and have the greatest visual impact if the ground has curving lines
  2. Place some filler in the mound so you can use less dirt-- this can be an upturned tub or more grit/gravel. Some soil will inevitably fall through so prepare to use more soil than what you originally planned
  3. Fill space randomly with larger rocks to give it a natural look
  4. Add grit, gravel, pebbles, or shale to the top, leaving some of the dirt and mulch exposed
  5. Add plants to the spots with the most dirt. make sure they have enough support and wont be blown away in the wind
  6. Water the rockery to help plants become established
  7. If any plants seem to be dying, remove them immediately and replant them in a more ideal location

Best plants for a rockery:

One of the most challenging aspects of building a rockery is selecting plants that can survive and thrive in such rocky conditions. This is a list of plants for rock gardens and rockeries that won't just survive, but will thrive.

These plants can be grown in sun or shade, or both. They can tolerate poor soil conditions and many have a creeping habit. These factors will make your rockery look like it's been there for years (even if you just planted it)!

Butterfly Milkweed

Butterfly Milkweed

The Best Growing Tips for Butterfly Milkweed in Your Garden The Butterfly Milkweed plant is certainly one of the most beautiful wildflowers in North America. Its beauty comes not only from its appearance but also from its fragrance. The plant that most people think of is A. Syriaca or the common plant. The Butterfly Milkweed blooms out in a star-spangled banner-type display. At the top of the stem is a myriad of tiny flowers colored in a watercolor-like light purple. They also bloom in most other colors of the spectrum. The plant is blooming in yellow, orange, green, and pink. To propagate themselves, these plants develop a seed pod that dries and then splits open to spread hundreds of seeds in the fall. How Butterfly Milkweed Attracts Pollinators and Benefits Your Garden Depending on the type of plant, it can grow from 2 to 5 feet in height. It grows in zones 3 to 9. This plant attracts the usual pollinating insects, such as bees, hummingbirds, and especially Monarch butterflies. Monarch butterflies love this plant because it is their main food source and also supplies a secure place for the female to spread her eggs, mostly on the underside of the leaves. These plants are fast spreading, giving them plenty of room in your garden. They like from 6 to 8 hours of sunshine. A good place in the garden is where they are protected from the wind so that you can control the spread of the seeds. This helps prevent the plant from taking over your garden. This also provides a haven for the Monarchs. Caring for Butterfly Milkweed A Complete Guide to Healthy Plants Most Butterfly Milkweed plants do well in just about any soil. The exception is the Swamp weed, which requires moist and humus soil. Plant them in a well-cultivated flowerbed that has been worked to a fine mix.

They are susceptible to most dirt, though they prefer slightly acidic. Fully grown plants generally stand 6" to 8" high; flower stalks can grow to 12". Each plant may extend up to 12". They quickly form mats, especially in shaded areas beneath other trees and shrubs. The plant is hardy enough to grow beneath black walnut trees. Ajuga Reptans A Low-Maintenance Ground Cover Solution The plant's growth speed can be controlled by where it is planted. Plants in shadier areas tend to grow faster than those in sunnier regions.

Shasta Daisy

Shasta Daisy

How to Grow Shasta Daisy for a Beautiful Summer Garden Shasta Daisy is a drought-resistant perennial with abundant flowers that blossom from late spring through premature fall. These hardy plants make excellent cut or dried flowers and survive in full sun and partial shade. Shasta Daisy Care Tips Keeping Your Flowers Blooming Strong It is a perennial with green and divided leaves that stays low to the ground. In spring and early summer, it bears immense flowers in clusters that develop into flat oval seed pods. With proper care, it can become a staple in your garden. The plant can be propagated by seed. The seeds need light to germinate, so sowing them in a ground area that receives adequate sunlight is essential. Germination should occur about two weeks after the seeds are sown. You will see the green shoots popping up above the ground surface. The young sprouts should be transplanted into larger pots with space for growth and root development, which may occur two months after transplanting them from the seedbed site. Why Shasta Daisy is the Perfect Addition to Your Perennial Garden To obtain the best results, it is recommended that the young plants be transplanted one foot away from the plants during the growing season. The plant will adapt to its new environment while providing fertilizer and water. Shasta daisy plants need regular pruning. This activity should be done frequently to avoid lumpy growth near the plant base. Proper pruning will allow light to circulate through the plant, provide more nutrients, and promote an optimum growth environment. They can be grown indoors or outdoors. If grown outdoors, ensure that the plant receives adequate sun and a moderate amount of water. If grown indoors, place the pot near a sunlight source. The soil should be kept moist but not too wet or dry for the healthy growth of the plants. In addition, if the Shasta Daisy is grown in pots, water must be continuously applied to the soil. It would be best to mistreat the plants with water at least daily. Watering and fertilization should be done as often as necessary to keep the soil moist during the growing season, which is essential for plant maintenance.
