Propagating Mandevilla Vines: A Step-by-Step Guide

With its glossy, bright green leaves and stunning trumpet-shaped blooms in shades of pink red, yellow or white, it’s no wonder why mandevilla makes such a popular climbing vine. Native to tropical regions of South America, mandevilla can be grown as an annual vine in northern climates or a perennial in zones 9-11.

While you can purchase mandevilla plants from nurseries and garden centers, propagating your own from cuttings or seeds is a great way to add more plants without spending money Not only that, but propagating mandevilla allows you to create new plants that are identical clones of the parent.

Read on to learn the ins and outs of propagating mandevilla vines through cuttings and seeds.

Overview of Mandevilla

Before we dive into propagation methods, let’s review some key facts about mandevilla vines

• Botanical name: Mandevilla sanderi or Mandevilla boliviensis

• Native to Brazil but grows well in tropics worldwide

• Evergreen woody vine growing up to 20 feet tall

• Produces showy, trumpet-shaped blooms spring through fall

• Thrives in warm climates, ideally zone 9-11

• Grown as an annual vine in containers in cooler zones

• Requires bright, indirect light and humid conditions

• Can be trained on a trellis or allowed to cascade from pots and baskets

Propagating Mandevilla from Cuttings

Taking cuttings from an existing mandevilla plant is the easiest way to propagate new vines. Here’s a step-by-step guide:

Supplies Needed

• Healthy parent plant
• Sharp, clean shears or pruners
• Rooting hormone (optional)
• Small pots with potting mix
• Clear plastic bags
• Labels

Selecting Cuttings

• Take 4-6 inch cuttings from the soft, new growth on the tips of the vine.
• Use a sharp blade to sever the cuttings just below a node.
• Remove all but the top 2-3 leaves.

Preparing Cuttings

• Dip the bare end of each cutting in rooting hormone powder if desired. This encourages faster root growth but isn’t essential.

Planting Cuttings

• Fill small pots with moist potting soil.
• Poke a hole and insert each cutting.
• Gently firm soil around the stem.

Caring for Cuttings

• Water to keep soil consistently moist but not soggy.
• Mist leaves daily to increase humidity.
• Cover pots with plastic bags to create a greenhouse environment.
• Place in bright, indirect light.
• Remove bags once roots appear in 2-3 weeks.

Transplanting New Plants

• Allow the rooted cuttings to grow larger over 6-8 weeks.
• Transplant into individual pots with trellises or hanging baskets.

In warm conditions, mandevilla cuttings can take root in as little as 2-3 weeks. Then you’ll have brand new specimens ready to train up trellises and arbors!

Propagating Mandevilla by Seed

Growing mandevilla vines from seeds is more challenging than taking cuttings, but still doable. Follow these steps:

Collecting Seeds

• Allow seed pods on the plant to ripen and dry out completely.
• Collect the seed pods and crack them open to remove the small seeds inside.

Storing Seeds

• Place seeds in an airtight container in the refrigerator for 1-2 months of cold stratification. This mimics winter dormancy.

Planting Seeds

• Fill starter pots with moist seed starting mix.
• Press the seeds lightly into the surface of the soil.
• Cover the pots with plastic to retain moisture and humidity.

Caring for Seedlings

• Keep pots warm, about 70°F (21°C).
• Keep the soil consistently moist but not saturated.
• Once sprouted, move to bright light.
• Thin to 1 plant per pot.
• Transplant into larger containers after 8-10 weeks.

From seeds, mandevilla vines will reach maturity and flower in around 9-11 months. Taking cuttings is certainly faster, but growing from seed can be rewarding!

Tips for Successfully Propagating Mandevilla

Follow these tips to ensure your mandevilla cuttings or seeds grow into healthy, vigorous vines:

• Start with a healthy parent plant – don’t use diseased or pest-infested stems for cuttings.

• Sterilize cutting tools with alcohol to prevent transferring diseases.

• For cuttings, select young, tender growth not old, woody stems.

• Dip cuttings in rooting hormone to increase the odds of root formation.

• Maintain high humidity around cuttings until rooted by covering with plastic bags.

• Keep newly rooted cuttings and seedlings warm, 70-80°F (21-27°C).

• Acclimate new plants gradually before transplanting into gardens, pots, or baskets.

Best Uses for Propagated Mandevilla Vines

The uses for mandevilla vines grown from cuttings or seeds are endless! Consider using your propagated plants for:

• Training up a trellis, pergola, or arbor
• Cascading from hanging baskets on patios or porches
• Adding striking vertical interest to garden beds and borders
• Climbing a pillar in outdoor container arrangements
• Topiaries or obelisks
• Adding bright pops of color to poolside plantings
• Growing in an enclosed courtyard or atrium
• Cascading from elevated pots and planters

The Takeaway on Propagating Mandevilla

With a bit of patience and proper care, propagating mandevilla from stem cuttings or seeds is a straightforward process. In no time you’ll have lush, flowering vines to adorn vertical spaces and add eye-catching color.

The vibrant blooms and fast-growing nature of mandevilla make it the perfect plant for propagation. Plus you’ll save money by multiplying your plants for free.

So don’t be afraid to propagate those mandevilla vines and put them to gorgeous use in your tropical garden. The stunning payoff is well worth the minimal effort required!
