Alice du Pont mandevilla vines are gorgeous tropical plants that can grow up to 20 feet long. Their shiny green leaves and stunning flowers in shades of pink, red, or white make them extremely popular for use in hanging baskets, trellises, and garden beds.

While Alice du Pont mandevillas aren’t difficult to grow indoors or outdoors, they do require some specific care – especially when it comes to transplanting Below you’ll find a step-by-step guide on how to successfully transplant your Alice du Pont mandevilla vines without stressing the plant

When is the Best Time to Transplant Alice du Pont Mandevilla Vines?

Timing is important when it comes to transplanting mandevilla vines Here are the optimal times

• Spring – The most ideal time to transplant is in early to mid spring after the last frost date. This gives the plant time to establish roots before summer heat arrives.

• Fall – Late summer to early fall is another good option. Transplanting in fall allows roots to grow before the plant goes dormant in winter.

• Avoid mid-summer – Transplanting during the hottest months of summer can put unnecessary stress on the plant. It’s best to avoid transplanting in mid-summer.

Preparing to Transplant the Mandevilla Vine

Proper preparation is key to ensure your mandevilla vine successfully re-establishes after transplanting. Here are some tips:

• Select a new container or garden location that is at least 2-4 inches larger than the current one Mandevillas have rapid growth and need spacious roots

• Check that the new container has several drainage holes at the bottom or be sure the garden location has well-draining soil. Mandevillas are prone to root rot if they sit in wet soil.

• Fill the new container about 1/3 full with a well-draining potting mix. Or amend garden soil with compost to improve drainage.

• Water the plant thoroughly 1-2 days before transplanting. This makes removal from the old container easier.

• Have the new planting location ready before taking the plant out of its existing container. Minimize the time roots are exposed.

Step-by-Step Transplanting Process

Follow these steps for safely transplanting your Alice du Pont mandevilla:

Remove from Current Container

• Lay the container on its side. Gently squeeze or roll the sides to loosen the root ball.

• Turn the container upside down supporting the plant and tap firmly until the plant slides out.

• If roots are dense and tangled, use a knife to gently score around the root ball to encourage new root growth outward.

Prepare Root Ball

• Use hand pruners to trim any dead or damaged roots. Healthy roots will be firm and white.

• If roots are heavily tangled, use your hands to gently tease some roots outward from the root ball.

Plant in New Container

• Place the root ball into the new container. The top should sit just above the soil line.

• Backfill soil around the root ball gently pressing to remove air pockets. Do not pack too firmly.

• Leave about 1-2 inches between the soil and the container rim for proper watering.

Plant in Garden Bed

• Dig a hole the same depth as the root ball and 2-3 times wider.

• If needed, improve drainage by mixing in compost or small rocks.

• Place the root ball into the hole and backfill with soil, gently pressing out air pockets.

• Ensure the top of the root ball sits level with the ground.

Caring for Newly Transplanted Mandevillas

Proper aftercare ensures your transplanted Alice du Pont mandevilla adjusts well. Follow these tips:

• Do not let the plant dry out – water whenever the top few inches of soil become dry. Prioritize consistent moisture.

• Stake or trellis vines to prevent wind damage to new tender growth.

• Avoid fertilizing for 2-4 weeks after transplanting to prevent burn.

• Move the plant to a shady location for 1-2 weeks to allow it to recover.

• Inspect often for signs of transplant shock like leaf yellowing or drop. Respond quickly.

• Be patient! It takes 4-6 weeks for roots to fully establish in their new location after transplanting.

Signs of Transplant Shock in Mandevillas

Despite best efforts, mandevilla vines may still struggle after being transplanted. Watch for these signs of transplant shock:

• Wilting, drooping, or curled leaves

• Leaves or flowers dropping

• Discolored yellowing leaves

• Lack of new growth

• Appearance of black spots on leaves

If you notice any of these, act quickly to help reduce stress on the plant. Increase water, add shade, mist leaves, and consider using a transplant fertilizer per label instructions. With proper care, even stressed plants typically recover.

When to Consider Professional Help

While DIY transplanting is perfectly fine for most gardeners, some scenarios call for professional help:

• If the plant is extremely large or unwieldy

• If you need to transplant in mid-summer out of necessity

• If signs of shock persist for more than 2-3 weeks after care

A professional landscaper has access to equipment for safely moving huge root balls. They also use growth hormones and other treatments to reduce transplant shock. For extremely tricky transplants or stubborn plants, calling the experts can be worth the cost.
