Growing Morning Glory Vines: A Comprehensive Guide to Cultivating Beautiful Blooms


Morning glory vines are a stunning addition to any garden, with their vibrant flowers and lush foliage.

Whether you’re a seasoned gardener or a beginner, this comprehensive guide will provide you with all the information you need to successfully grow morning glory vines.

From choosing the right trellis to caring for your plants, we’ll cover everything you need to know to ensure a bountiful display of these beautiful flowers.

Morning Glory String Trellis

Choosing the right trellis for your morning glory vines is essential for their proper growth and support. Morning glories are vigorous climbers and need a sturdy structure to climb upon.

A string trellis is an excellent option for morning glories as it provides ample support and allows the vines to twine and climb easily.

To create a string trellis, start by installing two vertical posts securely in the ground, about 6 to 8 feet apart. Attach a horizontal support beam between the posts at the desired height.

Then, run strings vertically from the top beam to the ground, spacing them about 6 inches apart.

As the morning glory vines grow, they will naturally wrap around the strings, creating a beautiful display.

Does Morning Glory Need a Trellis?

Morning glory vines are natural climbers and require some form of support to grow and flourish.

While they can scramble along the ground or other plants, providing a trellis offers several benefits.

A trellis helps keep the vines organized, prevents them from becoming tangled, and allows for better air circulation, reducing the risk of disease.

If you prefer a more natural look, you can also use other structures as support, such as fences, arbors, or pergolas.

Just ensure that the structure is sturdy enough to withstand the weight of the vines and provides enough space for them to climb.

How Far Apart to Plant Morning Glory

When planting morning glory seeds or seedlings, it’s important to consider the spacing between each plant. Morning glories are fast-growing and can quickly cover a large area.

To allow for proper airflow and prevent overcrowding, plant morning glory vines about 6 to 12 inches apart.

Spacing may vary depending on the variety of morning glory you’re growing, so it’s always a good idea to check the specific recommendations for the cultivar you have chosen.

Providing adequate spacing ensures that each plant has enough room to grow and receive sufficient sunlight and nutrients.

Growing Morning Glories in Pots

If you have limited space or want to add a touch of beauty to your patio or balcony, growing morning glories in pots is a great option.

Choose a large container with drainage holes to allow excess water to escape. Fill the pot with a well-draining potting mix, enriched with organic matter.

Morning glories grown in pots may require more frequent watering than those planted in the ground. Check the soil moisture regularly and water when the top inch of soil feels dry.

Place the pots in a location that receives at least six hours of direct sunlight each day.

Remember to provide a trellis or other support for the vines to climb. You can use a small trellis or even a bamboo stake inserted into the pot.

As the vines grow, gently guide them towards the support structure.

Morning Glory: How to Grow

Morning glories are relatively easy to grow, making them a popular choice for both novice and experienced gardeners. They thrive in full sun and prefer well-draining soil.

Before planting, prepare the soil by removing any weeds and loosening it with a garden fork or tiller.

Sow morning glory seeds directly in the garden after the last frost date, or start them indoors 4-6 weeks before the expected transplanting date.

If starting indoors, use biodegradable pots to avoid disturbing the delicate roots during transplanting.

Plant the seeds or seedlings about 1/2 inch deep and water thoroughly. Keep the soil consistently moist until the seeds germinate or the seedlings establish themselves.

Once the plants are established, reduce watering frequency, allowing the soil to dry slightly between waterings.

Morning glories are fast growers and can reach heights of 6 to 10 feet or more. Provide a trellis or other support structure for the vines to climb.

As the vines grow, gently guide them towards the support, helping them twine and attach themselves.

Can You Grow Morning Glories Indoors?

While morning glories are typically grown outdoors, it is possible to grow them indoors under the right conditions.

To successfully grow morning glories indoors, you’ll need to provide them with ample sunlight or artificial grow lights.

Choose a sunny window that receives at least 6-8 hours of direct sunlight each day. If natural light is limited, supplement it with fluorescent or LED grow lights.

Place the lights 6-12 inches above the plants and keep them on for 12-14 hours a day.

Use well-draining potting soil and ensure that the pots have drainage holes to prevent waterlogging.

Water the plants thoroughly when the top inch of soil feels dry, but avoid overwatering, as it can lead to root rot.

Morning glories grown indoors may not reach the same height as those grown outdoors, but they can still produce beautiful blooms.

Provide a trellis or other support for the vines to climb, and gently guide them towards it as they grow.

How to Grow Morning Glory from Seed Indoors

Growing morning glory from seed indoors allows you to get a head start on the growing season and enjoy earlier blooms.

Start by soaking the seeds in warm water for 24 hours to help soften the hard seed coat.

Fill biodegradable pots with a well-draining potting mix and plant the seeds about 1/2 inch deep.

Water the pots thoroughly and cover them with a plastic dome or plastic wrap to create a greenhouse-like environment.

Place the pots in a warm location with temperatures around 70-75°F (21-24°C). Once the seeds germinate, remove the plastic cover and provide bright, indirect light.

As the seedlings grow, thin them out, leaving the strongest ones to continue growing.

Transplant the seedlings outdoors after the last frost date, once the soil has warmed up.

Harden off the seedlings by gradually exposing them to outdoor conditions over a period of 7-10 days.

Drought-Tolerant Climbing Vines

If you live in an area with limited water resources or are looking for low-maintenance climbing vines, consider drought-tolerant alternatives to morning glories.

Some drought-tolerant climbing vines include:

  1. Bougainvillea (Bougainvillea spp.): These vibrant vines produce colorful bracts and thrive in hot, dry climates.
  2. Trumpet vine (Campsis radicans): Trumpet vines are known for their showy, trumpet-shaped flowers and can tolerate dry conditions once established.
  3. Honeysuckle (Lonicera spp.): Many honeysuckle varieties are drought-tolerant and produce fragrant flowers that attract hummingbirds.
  4. Passionflower (Passiflora spp.): Passionflowers are not only drought-tolerant but also offer unique and intricate flowers.

When growing drought-tolerant climbing vines, it’s important to provide them with well-draining soil and adequate water during the establishment period.

Once established, these vines can thrive with minimal water requirements.

Morning Glory Watering

Proper watering is crucial for the health and growth of morning glory vines.

While morning glories are relatively drought-tolerant, they still require regular watering, especially during dry spells.

Water the plants deeply, ensuring that the soil is thoroughly moistened. Avoid frequent shallow watering, as it can encourage shallow root growth.

Instead, water deeply once or twice a week, allowing the soil to dry slightly between waterings.

Monitor the moisture level of the soil by inserting your finger about an inch deep. If it feels dry at that depth, it’s time to water.

Adjust the frequency of watering based on weather conditions and the moisture retention of your soil.

During periods of heavy rainfall, reduce or suspend watering to prevent waterlogged soil, which can lead to root rot.

It’s important to strike a balance between providing enough water for the plants’ needs and avoiding excessive moisture.
