Pachypodiums can be a delightful addition to your plant collection, but they require special care to thrive. Here are some essential tips for successful cultivation:

1. Selecting the Right Location

Place your Pachypodium in a spot that receives abundant sunlight. These plants adore bright, indirect light and will flourish if provided with 6 to 8 hours of sunlight daily.

2. Soil and Drainage

Use well-draining soil with a mix of cactus potting mix and perlite. Good drainage prevents waterlogged roots and reduces the risk of root rot.

3. Watering Wisely

Pachypodiums are drought-resistant plants, so avoid overwatering. Allow the soil to dry out completely between waterings, and reduce watering during the winter months.

4. Temperature Tolerance

These succulents prefer warm temperatures and thrive in the range of 70-85°F (21-29°C). Protect them from frost, as they are not cold-hardy.

5. Pruning and Trimming

Remove dead or damaged growth to promote healthier plant development. Additionally, trimming leggy branches will encourage a more compact and attractive shape.

6. Repotting

Young Pachypodiums may require repotting every 2-3 years. Select a slightly larger pot, and gently handle the spiny stems during the process.

7. Pests and Diseases

Monitor your plants for signs of pests like mealybugs or spider mites. Address any infestations promptly with insecticidal soap or neem oil.

7.1. White-ish waxy strands around and among Pachypodium lamerei 

mealybugs

It sounds like you may have encountered a common occurrence with Pachypodium lamerei. The little white-ish waxy strands you’re noticing are most likely mealybugs. Mealybugs are small, soft-bodied insects that feed on plant sap, and they often leave behind a white, waxy substance as they move around the plant.

These pests can be a nuisance to Pachypodiums and other plants if left untreated. They tend to cluster in protected areas, such as the undersides of leaves or leaf axils, and can quickly multiply, causing damage to the plant over time.

To address the mealybug infestation on your Pachypodium, here are some steps you can take:

  • Inspect Your Plant: Examine your Pachypodium closely to confirm that it is indeed mealybugs causing the issue. Look for small, cottony clusters or white, waxy trails on the plant’s foliage.
  • Isolate the Plant: If you discover mealybugs, it’s essential to isolate the affected Pachypodium from other plants to prevent the infestation from spreading.
  • Remove Mealybugs Manually: For minor infestations, you can use a cotton swab dipped in rubbing alcohol to dab and remove the mealybugs from the plant. Take care not to damage the plant while doing so.
  • Insecticidal Soap: For more substantial infestations, consider using insecticidal soap. Follow the product instructions carefully and apply the soap to the affected areas of the plant.
  • Neem Oil Treatment: Another effective natural remedy is neem oil, which acts as both an insecticide and a fungicide. Dilute neem oil in water as per the instructions and spray it on the affected plant surfaces.
  • Pruning: If the infestation is severe and widespread, you may need to consider pruning heavily infested parts of the plant. Dispose of the pruned material away from other plants to avoid spreading the pests.
  • Monitor and Repeat: Continue to monitor your Pachypodium regularly for any signs of mealybugs and treat as necessary. Repeat the treatment as needed to ensure complete eradication.

Remember to follow the instructions on any insecticides or remedies you use, and be mindful of the safety of yourself and your plants during the process. Regularly inspecting your Pachypodium and taking prompt action against pests will help keep your plant healthy and thriving.

If you’re unsure about the best approach or if the infestation persists despite your efforts, consider seeking advice from a local plant expert or a horticulturist. They can provide specific guidance tailored to your plant and its unique situation.
