Smart Watering During Drought: Prioritize Plants, Conserve Water

Drought forces triage. Prioritize like a leader allocating scarce resources.

First Priority: Recent Plantings

New trees, shrubs, perennials (autumn/winter planted) lack deep water-seeking roots. Annual bedding (marigolds, impatiens) are likely casualties — sacrifice them to save a Japanese maple. Water when soil 5 cm down is dry. Drought-tolerant once established: Brachyglottis, Corokia, Gleditsia, Halimiocistus, Hippophae.

Second: Containers and Hanging Baskets

They're above the water table with only pot moisture. Check 5 cm down. Use catch trays to retain excess. Terracotta absorbs water plants can't reach. Drought-tolerant container plants: Arctotis, Lantana, Plectranthus, Portulaca, Zinnia.

Third: Thirsty Edibles

Tomatoes, peas, onions, cucumbers, marrows, lettuce need consistent moisture or produce stunted crops. Fruiting plants (strawberries, raspberries, currants, fruit trees) are 70–90% water — supply it during formation. Exposed/windy sites need extra water; wind desiccates foliage. Deep watering prevents this.

Fourth: Shallow-Rooted and Moisture-Lovers

At risk: Rhododendron, Azalea, Heather, Hydrangea, Birch (shallow roots); Hosta, Ferns, Helleborus, Sarcococca, Fatsia, Camellia (moisture-lovers). Wall climbers struggle in rain shadows — don't forget them. Drought-tolerant climbers: Clematis montana, Fallopia, Jasminum, Trachelospermum, Vitis.

Last: Lawns

Brown grass recovers after rain; roots survive dormancy. Utility seed mixes (No. 2, Manhattan) withstand drought. Fine grasses suffer more.

Application Methods

Sprinklers waste water. Hand-water at base (10 L/m²) or use seep hose/drip irrigation — woven through beds, it oozes water directly, efficiently. For runoff on dry soil, sink a gravel-filled 2L pot at the plant base and water into it.
