Knockout Rose Soaker Hose Watering and Mulching in Delaware

17 New Knockouts: Soaker Hose Runtime and Mulch Depth

Delaware shore: 7 Rainbow + 9 Red Knockouts planted late July. Quart pots, sandy soil, soil conditioner + bone meal. Soaker hose bought. Asks: runtime (1.5 hrs every other day?), mulch amount, over-mulch warning.

Soaker Hose Reality

• Output variable: 30 gal/hr at 50 ft (¼" hose) ≈ 0.5 gal/rose/hr
• 8 hrs = 4 gal/rose = 5-day supply (with light mulch)
• Burying hose reduces output over time
• Leave 2" clearance sides
• Pressure drop: start roses get more than end roses

Verification Method

1. Run 8 hrs, trowel-check depth
2. Check at 5 days for residual moisture
3. Adjust time accordingly

Watering Time

Night preferred (sandy soil dries fast in sun). Better absorption.
