The soil should be prepared by adding organic matter, such as compost or manure, to improve soil fertility and structure. Dig a hole that is slightly deeper and wider than the root ball of the plant. Place the plant in the hole, and backfill with soil. Water the plant thoroughly after planting.
Watering Needs
Protea intonsa Rourke has low to moderate watering needs. The plant can tolerate drought but prefers regular watering during the growing season to promote healthy growth and flowering. It is essential to avoid overwatering the plant, as it is susceptible to root rot. The frequency of watering depends on the soil type, weather conditions, and plant size.
Generally, the plant should be watered deeply once or twice a week during the hot and dry season. The soil should be allowed to dry slightly before the next watering. During the dormant season, the plant requires less water, and watering should be reduced accordingly.
Fertilization
Protea intonsa Rourke requires a balanced and slow-release fertilizer to promote healthy growth and flowering. The plant should be fertilized once a year, preferably in early spring before new growth starts. Use a fertilizer that has a low nitrogen content and a high phosphate and potassium content. Avoid using fertilizers that contain urea or ammonium nitrate, as they can damage the plant's roots.
To apply the fertilizer, scatter it around the base of the plant, and work it into the soil. Water the plant thoroughly after fertilizing to help the nutrients reach the roots. Do not over-fertilize the plant, as it can lead to salt buildup in the soil and damage the roots.
Pruning
Protea intonsa Rourke requires minimal pruning to maintain its shape and promote healthy growth. The plant should be pruned immediately after flowering. Remove any dead, damaged, or diseased branches, as well as any branches that are overcrowded or crossing each other. Prune the plant lightly to promote branching and bushiness.
The pruned branches can be used for cut flowers or for propagation. Cut the branches at a 45-degree angle, and remove the leaves from the lower portion of the stem. Dip the cut end in rooting hormone, and plant it in a well-draining and sandy soil mix. Water the cutting lightly and cover it with a plastic bag to maintain humidity. Place the cutting in a bright and warm spot, but avoid direct sunlight. The cutting should root within a few weeks.
Propagation of Protea Intonsa Rourke
