How to Grow T Rex Hosta

🌱 Planting Time

• Best planted in spring or early autumn, when soil is moist and workable.

🪴 Site Selection

• Choose a sheltered, shady position, such as under trees, along a north-facing wall, or in a woodland-style garden.
• Avoid areas with strong, drying winds that can damage large leaves.

🌿 Planting Steps

1. Dig a hole twice as wide as the root ball.
2. Enrich the soil with compost or organic matter.
3. Plant at the same depth it was in the pot.
4. Water thoroughly and apply mulch around the base.

Care Guide for T Rex Hosta

• 💧 Watering: Requires regular watering, especially in hot or dry weather — keep soil evenly moist.
• 🌱 Feeding: Apply a balanced slow-release fertiliser in spring.
• 🍂 Mulching: Add compost or leaf mould annually to maintain moisture and improve soil.
• ✂️ Tidying: Remove any damaged or yellowing leaves throughout the season.
• ❄️ Winter: Cut back dead foliage in late autumn. No lifting required — it’s fully hardy.

Pest Protection

Due to its size, T Rex can withstand some slug damage, but young shoots are still vulnerable.

• Use copper tape around containers or beer traps in borders.
• Consider slug-resistant treatment if planted in areas with high pest activity.
• Keep the area around the plant tidy to discourage hiding places for pests.

Companion Plants for T Rex Hosta

Growing T Rex in Containers
