• Application Technique: Scatter the fertilizer evenly around the root zone, avoiding direct contact with the foliage or stem.

Soil

Pineapple plants thrive in well-draining, slightly acidic to neutral soil. A mix of sandy loam with good drainage properties and organic matter such as compost or coconut coir provides an ideal growing medium for these tropical plants. If cultivating pineapple in containers, a well-formulated potting mix for tropical fruits can be used to ensure adequate aeration and moisture retention.

Soil Requirements:

• pH Range: 5.5-6.5 (slightly acidic to neutral)
• Drainage: Ensure the soil has excellent drainage to prevent waterlogging, particularly in regions with heavy rainfall or frequent irrigation.
• Texture: A sandy loam texture provides the right balance of drainage and moisture retention, promoting healthy root development.

Pruning

Pruning pineapple plants is a straightforward process that primarily focuses on removing spent or drying leaves, keeping the plant tidy, and promoting air circulation. While pineapple plants do not require extensive pruning, periodic maintenance helps prevent the accumulation of debris and enhances the overall appearance of the plant.

Pruning Guidelines:

• Leaf Pruning: Trim yellowing or desiccated leaves close to the base of the plant to maintain its vitality and neat appearance.
• Fruit Removal: After harvesting mature fruits, remove the central stem (once the fruit is cut) to encourage the development of new shoots and future fruiting.

Propagation

Pineapple plants can be propagated through the use of the crown, suckers, or slips. Each method offers a reliable way to produce new plants and expand your pineapple garden.

Propagation Techniques:

• Crown Propagation: Remove the crown (top leafy portion) of a mature pineapple fruit and allow it to dry for a few days before planting it in well-draining soil.
• Suckers and Slips: Separate young suckers or slips from the parent plant, ensuring that they have well-developed root systems before replanting them.
