Guide to Planting Field-Grown Root Balled Plants

Pros:

1. Established Roots: Typically stronger, established roots ensure better initial growth.
2. Immediate Impact: Larger plants provide instant structure and aesthetics.

Cons:

1. Heavy and Bulky: Can be difficult to transport and plant due to size and weight.
2. Seasonal Availability: Generally available only in the dormant season (autumn to early spring).

Preparation for Planting:

1. Unwrap Carefully: Remove any packaging material, but leave the burlap or wire basket on.
2. Keep plants moist: Plants should be kept moist until the time of planting.

Planting Process:

1. Dig a Hole: Make a hole twice the width of the root ball and the same depth.
2. Position Plant: Place the root ball in the hole, ensuring the top is level with the ground surface.
3. Do Not Remove Root Sack: Leave the burlap or wire basket around the root ball. It is bio degradable and will rot away naturally.
4. Backfill: Fill the hole with soil, firming gently around the roots to eliminate air pockets.
5. Water: Water deeply after planting to settle the soil and avoid wilting.

Possibility of Losses:

• Initial Shock: Some plants may suffer transplant shock, leading to potential losses.
• Mitigation: Proper care and consistent watering during the establishment phase can minimise this risk.

Main Causes of Failure:

1. Improper Planting Depth: Planting too deep or too shallow can stress the roots.
2. Poor Soil Conditions: Compacted or poorly drained soil can hinder root growth.
3. Insufficient Watering: Both under-watering and over-watering can lead to plant stress and failure. Strong wind can dry leafy pants.
4. Pest and Disease: Lack of protection and monitoring can result in damage from pests and diseases.

Tips for Success:

1. Stake Larger Plants: Support with stakes to prevent wind damage.
2. Mulch: Apply a layer of mulch around the base to retain moisture and regulate temperature.
3. Regular Monitoring: Check for signs of stress, pests, and disease, and address them promptly.

By following these guidelines and providing consistent aftercare, you can successfully plant and establish field-grown root balled plants in your garden.
