Seasonal Planting Guide for Raised Gardens in NZ

Seasonal planting helps you match plants with natural conditions in your region. This section breaks down each season so you can decide which crops suit your raised gardens in your NZ home.

Spring (September to November)

Spring days become milder, which prompts seeds to sprout faster. New shoots love warm daytime temperatures but still benefit from the occasional rainfall.

• Vegetables: Tomatoes, cucumbers, lettuce, capsicums, carrots, and radishes
• Herbs: Basil, coriander, chives, and dill
• Flowers: Petunias, marigolds, and impatiens

Expert Tips to Make Spring Plants Grow

Tip #1: Start tomatoes and cucumbers in small seed trays before moving them to your raised garden bed. 

This protects young plants from unpredictable spring weather and gives them a stronger start. Lettuces, capsicums, carrots, and radishes grow best in full sun—just be sure to thin out seedlings to give them space to grow and avoid weak, overcrowded plants.

Tip #2: Plant basil, coriander, chives, and dill in spots with partial shade or mild sun. 

Keep the soil damp but not waterlogged. Snip the top leaves to promote bushier and more vibrant growth. Remove any damaged leaves to maintain health. Space each herb a short distance apart to allow proper light and gentle air.

Tip #3: Choose bright areas for petunias, marigolds, and impatiens. 

These flowers thrive with moderate watering, so check the soil with your finger before adding moisture. Pinch off spent blooms to keep plants tidy. Add a light mulch layer to hold moisture. You can also provide stakes for taller stems if they look quite unstable.

Summer (December to February)

Summer offers long, warm days that push rapid growth. Many plants also enjoy extra light, which increases yields.

• Vegetables: Zucchini, beans, corn, and eggplants
• Herbs: Thyme, oregano, and parsley
• Flowers: Geraniums, begonias, and sunflowers

Expert Tips to Make Summer Plants Grow

Tip #1: Keep your vegetables’ soil moist but not too soggy, checking often during very hot spells.

Zucchini grows better in loose soil that drains well. Beans are like trellis or simple support, so place stakes near each seedling. Corn loves being in blocks for better pollination. Eggplants prefer direct sunlight.

Tip #2: Avoid over-fertilizing herbs to keep their flavours balanced.

Thyme and oregano flourish with moderate watering and sunny spots. Trim them often to encourage fresh and vibrant leaves. Parsley does well in shaded areas if it has very regular moisture. Remove any unhealthy stems as soon as they appear.

Tip #3: Manage the sunlight your flowers receive.

Geraniums and begonias like warm spots with indirect light. Water them when the topsoil feels dry. Sunflowers need direct sun and do well with deeper soil. Place stakes around young sunflowers to help them stand. Make sure there is enough space between each plant to reduce the risk of disease.

Autumn (March to May)

Autumn is when days start to cool down, but the soil often remains warm enough for continued growth. This time of year suits leafy greens and root vegetables that adapt to milder conditions.

• Vegetables: Spinach, kale, silverbeet, carrots, and beetroot
• Herbs: Mint, parsley, and rosemary
• Flowers: Pansies, violas, and chrysanthemums

Expert Tips to Make Autumn Plants Grow

Tip #1: Aim for consistent moisture levels to help roots develop well and avoid splitting or stunted growth.

Spinach, kale, and silverbeet handle cooler nights well. They like regular watering with good drainage. Carrots and beetroot do well in deeper soil that is free from rocks. Thin seedlings early to avoid crowding.

Tip #2: Trim leaves often to shape each plant. Remove debris to keep the area tidy.

Mint spreads fast, so consider using containers or barriers if you want to limit its spread. Parsley grows well in very moderate light with frequent moisture. Rosemary prefers sunny spots and somewhat dry soil between watering.

Tip #3: Plant flowers in spots that get some light but are still shielded from harsh wind.

Pansies, violas, and chrysanthemums bring extra colour during cooler months. Water them without letting them sit in puddles. Remove faded blooms to promote fresh buds. Add organic matter to improve soil texture and nutrient levels.

Autumn winds can often damage your plants. So, buying medium tall raised garden beds can help in protecting them. These beds are perfect for young plants.

Winter (June to August)

During winter, temperatures drop, but certain plants tolerate the cold. A bit of protection from frost helps keep them healthy.

• Vegetables: Broccoli, cauliflower, cabbage, onions, and peas
• Herbs: Sage, thyme, and winter savoury
• Flowers: Camellias, hellebores, and winter pansies

Expert Tips to Make Winter Plants Grow

Tip #1: Don't water vegetables too much to avoid soggy soil.

Broccoli, cauliflower, and cabbage handle lower temperatures but still need extra sun when possible. Onions and peas cope with chilly nights with mulch or straw around the base. Keep the area weed-free so these slower-growing plants get enough nutrients and space.

Tip #2: Cover some compost around the base of your herbs to lock in warmth.

Sage and thyme still produce leaves during very cold periods. Winter savoury remains hearty if it has decent drainage. Trim old stems to shape each plant and boost fresh shoots.

Tip #3: Remove old blooms or leaves to reduce disease risks and help strong new growth appear.

Camellias prefer acidic soil and steady, regular moisture. Hellebores do well in partial shade, especially under taller shrubs. Winter pansies offer colour but need shelter from harsh winds. Add organic matter to boost soil fertility.

Tip #4: Use deep gardening beds

Having raised gardens in NZ during winter can be challenging, but raised beds help regulate soil temperature. Our deeper raised beds provide better insulation against frost, keeping root vegetables and winter greens healthier. Adding a layer of mulch can further protect plants from extreme cold.

Sunlight will surely be scarce during winter, which is why having a large lightweight planter box that you can freely transfer anywhere within your garden is great. Ensure that your plants receive the sunlight they need!

Common Gardening Challenges & Easy Fixes

Starting your first garden can feel exciting but also intimidating. If you're worried about making mistakes, don’t be—every gardener learns as they go. Here are some quick fixes for common beginner problems:"

• Plants wilting? Likely overwatering—check if the soil feels damp before adding more water.
• Seedlings growing weak and spindly? They might not be getting enough sunlight—move them to a sunnier spot.
• Leaves turning yellow? It could be too much water or not enough nutrients—try adding compost for extra nourishment.

6 Tips for Planting in Raised Gardens

These tips help keep your raised gardens productive all year round. Let’s dive in!

Choose Deep Containers

Selecting raised outdoor planter boxes or tall raised garden beds helps you give plants enough root space. Deeper containers also help hold moisture longer.

Check that excess water can drain out. Opt for boxes or beds made with durable materials that can withstand weather.

Use Quality Soil and Compost

Soil health affects growth in a big way. Fill your raised gardens in your NZ home with a mix of garden soil and organic compost for better nutrients. Turn the top layer every few weeks to keep it loose. You should also remove weeds by hand to stop competition.

Rotate Your Plant Choices

Grow different crops each season to prevent soil depletion and pest buildup. For example, follow leafy greens with root vegetables, then switch to fruiting plants. This cycle stops certain pests from settling in. It also keeps the soil balanced.

Consider Companion Planting

Some plants help each other by repelling insects or improving soil. For instance, marigolds often discourage pesky bugs near tomatoes. Place strong-smelling herbs around leafy greens to deter certain caterpillars. Try pairing flowers with vegetables in the same bed. This approach keeps your raised gardens in your NZ home diverse and resilient.

Protect Young Seedlings

Avoid harsh weather by adding a simple cover or cloth during cold snaps. Keep an eye on strong winds that may damage fragile sprouts. 

If needed, place temporary fencing or a tree surround to shield delicate plants. Check daily for dryness beneath the covers. Quick attention ensures seedlings stay on track.

Make Sure Your Raised Garden in NZ Has A Durable Bed

Using a durable raised garden bed ensures better insulation for your soil, allowing plants to thrive in different seasons. Our raised garden beds, made from Aluzinc-coated steel, resist rust and weather damage, ensuring your garden stays productive for years.

Thriving Gardens Year-Round

Seasonal gardening allows you to match each plant's natural growth cycle. By choosing vegetables, herbs, and flowers that thrive in each season, you build a more dependable harvest and reduce the need for extra water or chemicals.

If you are a beginner, focus on a few crops at a time, then try new varieties as you gain confidence. You could check local nurseries, talk to neighbours with experience, or browse simple guides for additional details. 

Every great gardener starts somewhere, and the best way to learn is to begin. Even if you start small—with just a few pots on your patio—you’ll be amazed at how rewarding it is to grow your own food. Raised gardens in NZ make the process easier, keeping plants healthier and reducing maintenance. Pick the right raised planter boxes in NZ , plants suited to the season, follow a few simple steps, and enjoy the satisfaction of homegrown produce all year long.
