Gardening in Waitaki April 14th 2026

What an early introduction to winter wet received this week! Autumn is a time for reflection and planning. With cooler mornings and brilliant colour all around, April reminds us that although growth slows, the garden is far from sleeping; it is quietly preparing for the promise of spring. Once outside again, it will be back to the inevitable autumn task, leaves, leaves, and more leaves. While the workload can feel endless, the reward is a garden glowing in magnificent shades of gold, red, and orange. Truly, autumn is a second spring, when every leaf becomes a flower.

b>Most fallen leaves make excellent compost, although oak and walnut leaves take much longer to break down. I did compost some mixed with grass clippings, but I burned the excess in my trusty drum, returning the ash to compost heaps later. Keep layering compost bins with leaves, grass clippings, manure, and garden waste, watering between layers to encourage decomposition while warmth remains in the soil. Recent damp conditions have helped retain moisture in the ground, giving shrubs such as hydrangeas, camellias, rhododendrons, and azaleas an opportunity to harden wood before winter. Hydrangea blooms are now turning rich autumn tones, perfect for picking and drying by hanging upside down or leaving in a vase until the water evaporates. Leucadendron, protea, nandina, and nerines also provide excellent winter colour and long-lasting cut flowers. Nerines are now taking centre stage, sending up elegant flowers on tall stems and thriving in well-drained positions with little water during dormancy. Give winter flowering shrubs a dressing of compost as many are already forming buds. Only feed plants preparing to flower now; most others are slowing growth ahead of winter rest. On the coast, prune perennial wallflowers, mignonette, dentata lavender, and marguerite daisies to encourage fresh winter growth. Inland gardeners are better to take hardwood cuttings and overwintering them under protection, as frosts often damage established plants. Divide violas and clumping primulas now — one plant quickly becomes many and provides beautiful edging for spring displays. Trim spent flower heads from hebes to prevent legginess, Ranunculus corms are still available and well worth planting. Soak overnight before planting claws downward in groups for best effect. Lilies may be lifted only if overcrowded, keeping roots moist at all times, and replanted deeply, about three times the bulb height, except Madonna lilies, which prefer shallow planting and limy soil. Autumn remains an excellent time to plant evergreen shrubs and give hedges a final light trim. Small shrubs, conifers, camellias, azaleas, and rhododendrons transplant well now while soils are still warm. Peonies can also be moved once foliage yellows, planting crowns shallowly with buds just 5 cm below soil level. Lawns are responding well to cooler nights and renewed moisture. Repair grass grub damage by raking and resowing. Treat compacted areas with gypsum and fine compost while the soil is soft and moist. During the rain is a perfect time to spread. Vegetable Garden: Green manure crops are valuable in vacant beds, oats are ideal for autumn sowing, while blue lupins add nitrogen. Protect young veg seedlings from birds with raised netting. Broad beans can be planted now, adding a little potash beneath the seeds to help prevent rust. Leeks, carrots, spinach, snap peas, and spring onions can all be sown or planted. Remove shading from glasshouses and reduce watering as growth slows. Harvest pumpkins, always leaving the stalk attached to prevent rot. b>Fruit Garden: Apples, crabapples, quince, grapes, feijoa, and late peaches are ready for harvest and preservation. Pick surplus apples slightly unripe for storage, but leave some to ripen naturally on the tree. Gather walnuts promptly before pests find them, spreading them out in a dry, airy space so the green husks can dry and separate naturally. Feed citrus trees generously now with manure, seaweed, rock phosphate, dolomite, or citrus fertiliser, followed by mulch Cheers, Linda
