Sowing Time

Sowing time refers to the optimum time for sowing seed of a variety to encourage strong and vigorous growth. Whilst some varieties may be able to be sown outside the range suggested, they will generally perform best when sown in the approximate seasonal ranges provided.

A lot of seeds need consistent warmth to help them germinate. The best way to achieve this is to sow at the right time. By sowing in season when the conditions are optimum for seed germination you are increasing your chances of success. Slight bottom heat, approximately 20°C, can speed germination of many varieties.

To reference the best sowing times for a variety, we use sow numbers as detailed here:

Early Spring
Late Spring & Early Summer
Late Summer & Early Autumn

Growing Method

TRANSPLANT

Containers: Seeds can be sown in pretty much any container, tray or pot. Ensure the container has drainage holes in the bottom.
Mix Preparation: Use a good quality, seed raising mix and fill the container to within 2cm from the rim. Always use a commercially formulated seed raising mix to ensure sterility of the growing medium which will prevent possible infection of your seedlings. Use the palm of your hand to press down on the mix to create a firm surface.
Sowing: Sow seed evenly providing some space between seeds. Lightly cover the seed with seed raising mix, a sieve may be useful. Depth should be no more than twice the diameter of the seed. In the case of very fine seed no covering is needed. Use the palm of your hand to press down on the mix to create a firm surface.
Watering: Water the tray either by a watering can or hose using a very fine spray or place the tray into a tray of water and leave to soak until the surface appears glossy.
Environment: A piece of glass with a few thicknesses of paper on top may be placed over the container to prevent the mix surface from drying out. Turn glass daily so that the dry side is downwards. Cling film or recycled clear plastic meat trays can also be used. Check daily for signs of germination and remove covering as soon as seedlings appear, exposing the tender plants gradually to the full sunlight.
Seedling Growth: If growing on a window sill, turn the container every day to maintain an even growth and to keep the seedlings from stretching towards the light. When large enough to handle, transplant seedlings into a suitable container approximately 4cm apart. Harden off plants gradually exposing them to outdoor conditions before planting in their final growing location.
Moisture Management: Keep trays moist but not drenched to ensure germination and rapid growth. Overhead watering can be used initially but once seeds germinate and a leaf canopy establishes it is best to water from below by soaking the trays in water to avoid the development of diseases. When watering overhead, water earlier in the day to prevent having wet leaves overnight when the conditions are not as suitable for drying. The mix within the tray should appear dark and not brown to indicate appropriate moisture levels.

General Definitions

Annual

A plant that completes its entire life cycle (germinates, grows a plant, flowers, produces seed, dies) in one season. It may self-sow, thereby giving the impression of being perennial. Most annuals will flower 60 to 75 days from sowing.

Hardy Annual

An annual that does not need to be germinated indoors but can be sown direct into its growing position in the garden in spring and is tolerant of frost.

Tender Annual

An annual that is frost tender and can be germinated indoors. Sowing direct or planting outdoors must not occur until all danger of frost has passed (also known as a Half-Hardy Annual).

Biennial
A plant that completes its entire life cycle in two years - growing in the first, reproducing and dying in the second. Typically, but not always, producing flowers only in the second year.

Perennial

A plant that can live for more than two years, surviving the winter and flowering each year from the second season. Perennials may flower within 90 days of sowing in their first season but will more typically flower in their second
season.

Hardy Perennial

A perennial that is frost-tolerant.

Tender Perennial

A perennial that is frost tender.

Hardy

A plant that will survive frost.

Tender

A plant that will not survive frost.

Bolting

Going to seed. Premature formation of a seed stalk, may be due to plant stress.

Botanical Name

The formal scientific name conforming to the International Code of Nomenclature for plants. Identifies the genus and species to which the plant belongs useful in distinguishing plants uniquely.

Cotyledon

The seed leaves or first leaves that emerge from a germinated seed, different in form from the later true leaves.

True Leaves

The leaves that emerge after the cotyledons which are indicative of the true form
of the plant’s leaves.

Determinate

Growth stopped by development of terminal flower buds. A dwarf/bush variety which sets fruit in a concentrated period.

Indeterminate

Growth continuing indefinitely when leaf buds form at the tip of the growth. These varieties need to be staked and continue to set fruit until frost.

Heirloom

A variety that is older than two generations (50 years). Can also be referred to as “Heritage” and is always an open pollinated variety selected for garden performance (flavour, long harvest).

Hybrid

A plant resulting from a cross between two parent plants to give a genetically superior plant i.e. improved disease resistance, better vigour, more uniform harvest. Normally, seed saved from hybrids does not grow true to type.

F1 - The first generation of such a cross. Denoted in the name of the variety.

F2 - The second generation of such a cross etc.

Open Pollinated

Natural cross between plants of the same variety. Refers to non-hybrid seeds or plants.

NPK

Basic nutrient needs of plants:

Nitrogen
(N) - for green growth, healthy soil and microbial activity

Phosphorus
(P) - for flower, fruit and seed production; vigorous roots and disease resistance

Potassium
(K) - essential for building plant tissue (important for young plants) and the
quality and size of fruit.

pH A measurement for the acidity/alkalinity of soil, needed for nutrientavailability and microbial activity.

Scarification

Thepractice of scratching or notching the seed coat to assist germination. Usually
applies to hard coated seed.
