Coffee sacks a useful tool
black garbage bags and come with their own ventilation. I tried growing potatoes in sacks but found they dried out too quickly. Instead I use sacks to disguise grow bags of potting mix and ugly plastic pots.
DIVIDE YOUR PRIMROSES AND POLYANTHUS
The four Ps. Along with pansies, primulas, primroses and polyanthus are reliable for cheerful flowers through winter. There can be some confusion with the names, however, as polyanthus, primula and primrose are often used interchangeably. That’s understandable because primroses and polyanthus are both members of the primula genus which has around 400 species.
The name primula comes from the Latin primus or first as they are among the first of the spring flowers.
Primroses (Primula vulgaris) have clusters of flowers on erect stems arising from a rosette of basal leaves. Flowers can be single or grouped together as an umbel on a single stem. They are often yellow but have been bred in many other colours. Polyanthus, meaning many flowers, have larger clusters of flowers held above the leaves on sturdy stems. They are hybrids of the cowslip (Primula veris) and the common primrose (Primula vulgaris).
Polyanthus have been extensively hybridised and come in a wide range of often multicoloured petals. There are also auriculas (Primula auricula), the subject of much interbreeding for display by Florists Societies during the 18th and 19th centuries.
These perennials should not be confused with Primula malacoides, aka fairy primrose, which is a winter and spring flowering annual. The flowers look more delicate and the stems are much taller (to 30cm).
When it comes to bedding plants, more is more! A generous patch looks better than a sparse sprinkle dotted about. Luckily it’s easy to bulk up your stock of plants. Over a season, primroses and polyanthus grow into clumps of easily divided plantlets called crowns. Dig up each plant, shake or wash off excess soil and tease the roots of each crown apart. Trim off any woody or dead bits and replant. Keep moist until they are established. Feed with dried blood or tomato fertiliser when buds start to form.
It’s getting a bit late in the season but in warm areas there’s still time to start Primula malacoides, pansies and their mini relatives – violas –from seed in trays. Seedlings are also available in punnets or as potted colour from garden centres.
WHEN TO LIFT AND MOVE DAFFODILS
Daffodils don‘t need to be lifted and stored every year but if they look like the ones above, then it‘s This column is adapted from the weekly e-zine, get growing, from New Zealand Gardener magazine. For gardening advice delivered to your inbox every Friday, sign up for Get Growing at: getgrowing.co.nz time to give them a bit more elbow room.
Ideally, move them before they start to sprout as they will be easier to handle. Dig up the whole clump with a fork. Shake or rinse off excess soil. These daffodils had 1-2cm roots that needed to be gently teased apart. Refresh the soil with compost and bulb fertiliser and replant a few in the original spot. The rest can be given away or replanted elsewhere in the garden or in pots. The smallest baby bulbs are unlikely to flower this spring. I planted them separately in a large shallow tub to grow on for a year before finding them a new home in my garden.
