Growing Geranium Orion Plants From Seed vs. Planting Nursery Plants

You can either start Geranium Orion plants from seeds or purchase young nursery plants for your garden.

Either method works well. However, you should consider the time investment necessary. While purchasing nursery plants will ensure a blooming garden the same season, growing Geranium Orion from seed means waiting at least one year for flowers.

Cost-wise, purchasing seeds is typically less expensive than purchasing young plants from a nursery.

What to Do Before Planting

Before planting Geranium Orion, you’ll want to identify an ideal location with well-draining, moderately moist soil and enough sunlight. Then gather supplies like a shovel or trowel and compost or balanced, slow-release fertilizer pellets.

The Best Soil for Geranium Orion

The Best Soil for Geranium Orion

Regardless of pH and composition, Geranium Orion thrives in just about any soil as long as it is rich, moderately moist, and well-draining.

How to Plant a Geranium Orion

First, dig a hole that’s slightly larger than your Geranium Orion’s root ball. Add a layer of compost of sprinkle some fertilizer pellets into the bottom of the hole. Place the Geranium Orion in the hole, so that the base of its stem is level with the ground or the top of your potting mix in a container.

If your soil is not well-draining or tends to become waterlogged, mix some perlite or sand into your potting mix to improve aeration and drainage before filling in around the plant’s roots.

If planting more than one Geranium Orion, be sure to leave enough space between the plants to allow for ample growth, about 3 feet.

Geranium Orion Light Preferences

To encourage abundant blossoms and discourage legginess, Geranium Orion needs at least 4 to 6 hours of full, direct sunlight each day.

In climates with hotter summers, aim for a location that offers part shade in the afternoon and evening. In cooler climates, look for the sunniest location possible.

Geranium Orion Temperature and Humidity Preferences

Geranium Orion is winter hardy down to -30°F and thrives in ambient temperatures ranging from 65°F to 95°F. These plants prefer low to moderate humidity but can tolerate high humidity and more moist conditions as long as their soil drains well.

How to Care for Geranium Orion

Watering Geranium Orion Plants

Most problems with Geranium Orion occur as a result of watering too much or too little. They need about 1 inch of water each week and even moisture is incredibly important for young plants that are not yet well established.

Water ground plants daily during spring and summer, providing more or less water depending on how hot and dry the weather is and how well your garden soil drains.

Water container plants when the top 1 or 2 inches of potting soil feels dry to the touch. Make sure all excess water drains from the containers.

How, When, and Why to Fertilize Geranium Orion

Fertilizer replenishes the nutrients in the soil around your Geranium Orion’s roots, helping it grow and blossom.

Add a balanced, slow-release fertilizer to your garden soil or potting mix when first planing a Geranium Orion. Fertilize every year after the last frost of spring has passed by applying balanced fertilizer pellets or liquid fertilizer to the top of the soil below the plant’s foliage.

Pruning and Cutting Back a Geranium Orion

Pruning and Cutting Back a Geranium Orion

Geranium Orion does not require much pruning. However, they can be cut back to help shape and control their growth. Additionally, removing spent blooms and cutting the plant back at the end of the summer season can help encourage another round of blossoms in the fall.

Propagating Geranium Orion

There are several effective methods for propagating Geranium Orion:

  • Root bulbs can be split and repotted in the autumn, winter, or early spring.
  • Seeds can be collected from the plant throughout summer.
  • During the summer, you can collect semi-rep woody cuttings from the plant to root in water.
  • Roots can be propagated in water any time of the year.

When propagating by cutting or root, use a growth hormone to encourage new sprouts.

Overwintering Geranium Orion

Geranium Orion can be overwintered outdoors in most climates in the United States – as winter temperatures do not drop below -30°F.

Potted plants should be overwintered in a slightly warmer, sheltered location such as a greenhouse.

When and How to Repot Geranium Orion in a Container

When and How to Repot Geranium Orion in a Container

Geranium Orion rarely requires transplanting. However, if your plant becomes too big for its container, it can be removed, split into two or three smaller plants, and transplanted into new containers.

Transplanting is best performed in the fall or early winter when the plant is dormant. Transplanting, however, can also be done in early spring before your plant has entered the growing season.

If you plan to split your plant into more than one, be sure you have enough well-draining containers and potting mix available for all of your plants transplanting.

To transplant a Geranium Orion, grasp the plant by the base of its stem and gently tease it out of its pot. Loosen any potting mix from the plant’s root ball.

Add a layer of potting mix to the bottom of your container and place your plant inside, gently filling in around its roots with the fresh potting mix so the start of its stem is aligned with the soil line.

Gently pat down the soil and water thoroughly, ensuring all excess moisture drains.
