Method 1: Using Seeds to Propagate a Mandevilla Plant

It is the easiest and beginner-friendly method of propagating a Mandevilla plant. For the execution of this method, you would require fresh Mandevilla seeds; you can get some from your existing adult Mandevilla plant; alternatively, you can also ask the good neighbor next door who owns a beautiful garden.

Step 2:

Once the pods are dried, you can extract the seeds from inside. You can extract the seeds manually; it won’t take long to do so. Just be careful and try not to damage the seed.

Step 3:

Soak the Mandevilla seeds in room temperature water for about 12 hours. You can use normal tap water for the purpose, no fancy requirement here.

Step 4:

Plow the soil where you need your new Mandevilla plant to grow. Select warm and moist areas without direct sunlight since Mandevilla plants thrive in such areas.

Post propagation is a very delicate and crucial time for the plant. Since the plant is adjusting to the new environment, it is vulnerable to pests and insect attacks. Hence it would help if you were very diligent and constantly lookout for possible pests and insects. If your plant becomes infested with pests, use pesticides and insecticides to protect it.
