How to Water Golden wonder tree?

Senna spectabilis requires a deep watering, which means you should soak the soil thoroughly until water drains out of the bottom of the pot. This ensures that the roots have enough moisture available to them. A general guide is approximately 1000 milliliters per session for mature plants in large pots. Adjust this based on the soil's ability to retain moisture and the environment the plant is in.

Senna spectabilis typically requires a balanced fertilizer. Apply a diluted liquid fertilizer at half strength to avoid over-fertilization. Use around 100 ml of liquid fertilizer per plant per application.

How to Prune Golden wonder tree?

Pruning Time: Spring, Summer

Start by assessing your Senna spectabilis for any dead or diseased branches and remove them using clean and sharp pruning shears. Cut close to the main branch without damaging the stem. Focus on maintaining a balanced shape and thin out congested areas to improve air circulation and light penetration. To shape your tree, trim overgrown branches to maintain the desired form. Remove crossing branches and ones growing inward towards the tree center. This practice not only keeps your tree aesthetically pleasing but also prevents potential pest infestations and diseases.

How to Propagate Golden wonder tree plant?

Propagate Time: Spring,Summer

Collect seeds from mature pods on the Senna spectabilis when they turn dry and brown. Ensure the seeds are fully matured to increase the chances of successful germination.

Select healthy, non-flowering stems for cuttings. Cut the stem at a 45-degree angle, around 4-6 inches long, and remove the leaves from the bottom half to encourage root development.

Plant seeds or prepared cuttings in a mixture of peat and perlite. Ensure the soil is well-draining and place the container in a warm, bright area, avoiding direct sunlight.

How to Repot Golden wonder tree plant?

Repotting frequency: Every 2-3 years

You should consider repotting your Senna spectabilis when you notice roots growing out of the drainage holes, or when growth seems stunted. These are clear signs that the plant needs more space to continue thriving.

Choose a pot that is one size larger than the current one, with good drainage holes. This ensures enough space for root growth and prevents waterlogging, which can lead to root rot.

Opt for a well-draining potting mix, possibly incorporating sand or perlite. This helps in providing adequate aeration and prevents excessive moisture retention, promoting healthy root development.
