Capers

Family: Capparaceae

Genus: Capparis

Species: spinosa

History

Capers come from the tough little buds of a Mediterranean shrub, grown since ancient times along rocky coastlines. Mentioned in Greek and Roman texts, capers were prized for their sharp bite and ability to enhance sauces and meats. Though not widely cultivated in Australia, they've carved out a niche in dry-climate gardens and gourmet kitchens, where their tangy flavour shines.

Where to Plant

Shady Spots & Herb Gardens

Shady Spots & Herb Gardens
• Areas receiving dappled or indirect sunlight, often near trees or buildings
• Best for shade-tolerant herbs like mint, parsley, or greens like spinach
• Helps prevent sun stress and conserves moisture
• Often used in cooler corners of the garden

In-Ground Garden Beds

In-Ground Garden Beds
• Traditional garden beds dug directly into the soil
• Suitable for deep-rooted crops and long-term plantings
• Offers natural soil ecology and drainage benefits
• Requires proper soil preparation and weed management

Containers & Pots

Containers & Pots
• Portable planting vessels suited for patios, balconies, and small areas
• Provide complete control over soil composition and drainage
• Great for herbs, greens, compact vegetables, or ornamental plants
• Allow plants to be moved to follow sun, shade, or seasonal conditions

Pre-treatment

Scarification

• Gently rub the seed coat with sandpaper or nick it with a blade
• Aim to just break the outer shell without damaging the inside
• Soak scarified seeds in water for a few hours before sowing
• Common for hard-coated seeds like nasturtium or sweet pea

Soaking in Water

• Place seeds in a cup of clean, room-temperature water
• Soak for 8–24 hours depending on seed type
• Plant immediately after soaking to prevent rot
• Useful for large or hard seeds like beans and beetroot

Stratification (Cold)

• Mix seeds with moist vermiculite or paper towel in a sealed bag
• Refrigerate for 2–12 weeks depending on species
• Mimics natural winter conditions to break dormancy
• Ideal for perennials and cold-climate wildflowers

Sowing Method

Start in Trays

• Fill seed trays or punnets with quality seed-raising mix
• Sow seeds at the correct depth—refer to seed packet for guidance
• Place trays in a warm, sheltered location with good light
• Mist or bottom-water to avoid disturbing small seeds
• Transplant seedlings once they develop 2–4 true leaves

Direct Sow

• Sow seeds directly into prepared garden soil or outdoor containers
• Best for plants that dislike transplanting, such as root vegetables and beans
• Loosen soil and remove weeds before sowing
• Sow at the recommended depth and spacing, then water gently
• Keep the area moist until germination and thin seedlings if needed

Watering

Medium

• Benefits from regular watering, especially during active growth or flowering
• Soil should remain moist but not soggy—allow topsoil to dry slightly between waterings
• Ideal for most vegetables, herbs, and flowering annuals
• More frequent watering may be needed during hot or windy weather
• A layer of mulch can reduce water loss and improve consistency

Fertilisation

Frost

Frost Tolerant

These plants can tolerate light to moderate frosts and may survive through cooler seasons.

Maintenance and Harvesting

Capers are best pruned back after flowering to keep compact. Water sparingly and provide good drainage. Remove weeds and mulch with gravel to suppress competition.

Pests and Diseases

Aphids

Aphids are tiny, soft-bodied insects that cluster on new growth and the undersides of leaves. They suck sap from plants, causing leaves to curl, yellow or become distorted. As they feed, they excrete sticky honeydew that encourages sooty mould, and colonies can build quickly in warm weather.

Start with organic controls: blast colonies off with a firm jet of water, encourage beneficial insects like ladybirds and lacewings, and spray neem oil or insecticidal soap to disrupt feeding. Keep plants well watered and avoid excess nitrogen that promotes soft growth. If pressure remains high, selective chemical sprays can be used sparingly, taking care to protect pollinators and beneficials.

Leaf spot

Leaf spot describes several fungal or bacterial diseases that create dark, often round lesions on foliage—sometimes with yellow halos. Severe infections cause premature leaf drop and reduced vigour, especially during warm, wet spells or when leaves stay damp.

Reduce spread by removing infected leaves, watering at the base, and spacing plants for airflow. Mulch to limit soil splash and rotate crops. Organic preventatives include copper and sulfur sprays applied early. If disease escalates, registered fungicides offer a chemical backup.

Crown / root rot (Wet)

Crown and root rots are caused by water‑loving fungi that attack stems at the soil line and roots below. Plants yellow, wilt, and eventually collapse because their roots can no longer supply water and nutrients—most common in heavy, waterlogged soils.

Prevention is key: improve drainage, raise beds, and water deeply but less often. Avoid injuring stems at the soil line and rotate away from affected beds. Solarising soil in summer can knock back pathogens. Chemical drenches have limited benefit in home gardens and are best used preventatively rather than curatively.

Mealybugs

Mealybugs can affect plant health and yields in home gardens. Typical symptoms include slowed growth, discolouration, and reduced productivity, often triggered by weather, nutrition, or cultural conditions.

Start with cultural fixes: rotate crops, improve soil with compost, water consistently, and choose resistant varieties. Organic sprays or amendments can reduce severity; chemical options are a last resort and should be used carefully and in accordance with labels.

Cold / frost injury

Cold / frost injury can affect plant health and yields in home gardens. Typical symptoms include slowed growth, discolouration, and reduced productivity, often triggered by weather, nutrition, or cultural conditions.

Start with cultural fixes: rotate crops, improve soil with compost, water consistently, and choose resistant varieties. Organic sprays or amendments can reduce severity; chemical options are a last resort and should be used carefully and in accordance with labels.

Scale insects

Scale insects can affect plant health and yields in home gardens. Typical symptoms include slowed growth, discolouration, and reduced productivity, often triggered by weather, nutrition, or cultural conditions.

Start with cultural fixes: rotate crops, improve soil with compost, water consistently, and choose resistant varieties. Organic sprays or amendments can reduce severity; chemical options are a last resort and should be used carefully and in accordance with labels.

Nutrient chlorosis

Nutrient deficiencies lead to pale leaves, poor growth, and reduced yields; patterns differ by nutrient—for example, nitrogen causes overall yellowing, iron causes interveinal chlorosis on young leaves, and potassium can scorch leaf edges.

Test soil if possible, feed with a balanced organic fertiliser, and top‑dress with compost. Maintain even soil moisture to aid uptake. Foliar feeds can give a quick boost while longer‑term soil health is restored.

Growing Tips

• Capers is slow to establish and needs heat; plant in the warmest, sunniest position.
• Capers hates wet feet; use very free-draining, gritty soil and avoid over-watering.
• Capers flowers poorly where winters are very cool; a long, warm season improves bud set.
