Guide to Storing, Sowing and Germination

The vibrant and beautiful red mandevilla plant is a popular choice for many gardeners. With its stunning red flowers and lush green foliage, it adds a touch of tropical beauty to any garden or container. If you are interested in growing this stunning plant from seeds, it is essential to understand the proper techniques for storing, sowing, and germinating red mandevilla plant seeds. In this guide, we will walk you through the process step by step.

Storing Red Mandevilla Plant Seeds

Before you can sow red mandevilla plant seeds, it is crucial to store them properly to ensure maximum viability. Here are some guidelines to follow when storing your seeds:

1. Harvesting Seeds: Wait until the mandevilla plant has finished blooming, and the flowers have started to fade. This is an indication that the seed pods are beginning to form. Allow the seed pods to fully mature on the plant before harvesting.

2. Removing Seeds from Pods: Once the seed pods have turned brown and dried out, carefully cut them from the plant using a pair of clean, sterilized scissors or pruning shears. Gently break open the pods and collect the small black seeds inside.

3. Drying Seeds: Place the collected seeds on a clean paper towel or tray and allow them to air dry for about a week. Make sure they are spread evenly and not clumped together to prevent mold or mildew formation.

4. Storing Seeds: Once completely dry, transfer the seeds into airtight containers such as small glass jars or plastic bags. Store them in a cool, dark place with low humidity, such as a refrigerator or cellar. Properly stored mandevilla seeds can remain viable for up to two years.

Sowing Red Mandevilla Plant Seeds

After storing the mandevilla plant seeds, it is time to sow them. Follow these steps for successful sowing:

1. Preparing Seed Trays or Pots: Choose a well-draining seed tray or small pots with drainage holes. Fill them with a high-quality seed starting mix that is moist but not overly wet.

2. Sowing Seeds: Sprinkle the mandevilla seeds evenly over the surface of the soil. Avoid overcrowding by leaving some space between the seeds.

3. Covering Seeds: Lightly sprinkle a thin layer of soil or vermiculite over the seeds to cover them. This layer should be no more than 1/4 inch thick.

4. Watering: Gently water the soil using a misting spray bottle or a fine watering can. Maintain moisture in the soil without soaking it.

5. Providing Warmth and Light: Place the seed trays or pots in a warm location that receives bright, indirect sunlight. A temperature range of 70-80°F (21-27°C) is ideal for germination.

6. Germination Period: Red mandevilla plant seeds typically take 2-4 weeks to germinate. During this time, ensure that the soil remains consistently moist, but avoid overwatering as it can lead to rotting.

7. Transplanting Seedlings: Once the seedlings have developed their second set of true leaves, they are ready to be transplanted into individual pots or containers filled with potting soil. Handle the delicate seedlings carefully to avoid damaging their roots.

Germination Tips and Troubleshooting

While growing red mandevilla plants from seeds is relatively straightforward, here are some additional tips and troubleshooting advice:

• Temperature Control: Ensure that the temperature remains consistent throughout the germination period. Fluctuations in temperature can slow down or inhibit germination.

• Lighting Conditions: While red mandevilla plants prefer bright, indirect sunlight, direct sunlight can be too intense for seedlings. Provide shade or use a grow light if necessary.

• Watering Schedule: Keep the soil evenly moist but avoid overwatering. Overwatering can lead to root rot, while underwatering can cause the seeds to dry out and fail to germinate.

• Pruning Seedlings: Once the seedlings have established themselves, it is advisable to pinch off the top growth to encourage branching and lateral growth.

• Patience: Remember that germination can take time and may vary between individual seeds. Be patient and wait for the seedlings to emerge.

In conclusion, growing red mandevilla plants from seeds can be a rewarding experience for any gardener. By following the steps outlined in this guide, you can successfully store, sow, and germinate red mandevilla plant seeds. With proper care and attention, you will soon be rewarded with vibrant red blooms and lush foliage that will add a touch of tropical beauty to your garden or container.
