Why Plant By The Moon Phases?

People plant by the phases of the moon, a practice known as lunar or moon gardening, because it is believed the moon's gravitational pull affects moisture levels in the soil and within the plant itself. This ancient practice suggests that planting during specific phases can optimise growth, with the belief that a waxing moon (from new moon to full moon) is best for above-ground crops, while a waning moon (from full moon to new moon) is better for root vegetables. While scientific evidence is limited, many traditional and modern gardeners swear by its effectiveness.

Planting by the Moon – January 2026

Full Moon (Waning Gibbous) 3rd January

• The Effect: Gravity is high (peak moisture), but light begins to decrease.
• What Happens: Sap flow starts to reverse and go downwards, focusing energy on the roots. The high soil moisture at this time is excellent for root development.
• Best for: Planting root crops and perennials.
• Plant: Carrots, onions, potatoes, beets, bulbs, and perennials (rhubarb, asparagus).

Plant root crops and perennials, take cuttings, divide plants, and harvest.

Third/Last Quarter (Waning Crescent) 11th January

• The Effect: Gravity is low and light is low.
• What Happens: This is considered a resting period for plants. Sap flow is low.
• Best for: Maintenance rather than planting.
• Tasks: Weeding, pruning, harvesting, and preparing soil. Mowing during this time is said to slow regrowth.

New Moon (Waxing Crescent) 19th January

• The Effect: Gravity is strong, pulling water up, and moonlight is increasing.
• What Happens: Sap flow is high and rising. The increasing light is thought to encourage leaf growth.
• Best for: Planting above-ground annual crops that produce their seeds outside the fruit (leafy greens).
• Plant: Lettuce, spinach, celery, broccoli, cabbage, cauliflower, and grain crops.

First Quarter (Waxing Gibbous) 27th January

• The Effect: Gravitational pull lessens, but moonlight is strong and increasing.
• What Happens: Sap is still flowing upwards, supporting strong leaf growth.
• Best for: Planting annuals that produce seeds inside the fruit.
• Plant: Beans, melons, peas, peppers, squash, and tomatoes.

What to plant in January

Bundaberg's January weather is hot, humid, and often wet. The focus this month is on heat-tolerant crops, protecting your soil from the harsh sun, and managing moisture to prevent fungal issues.

Vegetables & Herbs

You want quick-growing crops or plants that love the sub-tropical heat.

Best Performers: Sweet Corn, Snake Beans, Sweet Potato (runners), Capsicum, Chillies, Eggplant, Rosella.

Leafy Greens: Basil (loves the heat), Lemongrass, Mint (keep in pots), Rocket and Lettuce (only if grown under shade cloth and watered daily).

Root Veg: Radish (quick harvest), Beetroot, Carrots (sow deep to keep cool).

Vines: Cucumber, Zucchini, Pumpkin, Watermelon, Rockmelon.

Tip: Lift melons off the moist soil using straw or an overturned saucer to prevent rot.

Flowers

Plant these to attract pollinators and add colour that withstands the UV.

Sun Lovers: Sunflowers, Marigolds (great for pest control), Zinnias, Petunias, Cosmos, Celosia, Portulaca (pigface), Vinca.

Natives: Kangaroo Paw, Bottlebrush, Grevillea.

Fruit Trees

January is a good time to plant evergreen fruit trees, provided you can keep the water up to them while they establish.

Tropical/Sub-tropical: Mango, Banana, Papaya (Paw Paw), Dragon Fruit cuttings, Citrus (Lemon, Lime, Orange), Passionfruit vines.

January Garden Jobs in Bundaberg

Mulch Heavily: The sun is your soil's enemy right now. Apply sugar cane mulch or lucerne to a depth of 5-7cm to keep roots cool and retain moisture.

Watering: Water early in the morning (before 9 AM) to prevent evaporation. Avoid watering late in the evening to reduce the risk of fungal diseases like powdery mildew, which thrives in Bundaberg's humidity.

Shade: Young seedlings will burn. Use shade cloth or old white sheets to protect new plants during the hottest part of the day (11 AM - 3 PM).

Pests: Watch out for lawn grubs (armyworm) after heavy rains.
