When To Plant Dahlias Nz: What are dahlias’ origins? | Dahlia Growing Guide Mexico sent several Dahlia plants to the Madrid botanical garden in 1789 with the advice that they be used as food. This suggestion wasn’t well received at the time. Up until Joséphine de Beauharnais, the wife of Napoleon had a sudden urge to cover her entire garden in Dahlias. Once they established the new standard, everyone wanted a few of these stunning beauties in their yard.

The Dahlia had to contend with this unfair status for years as they quickly gained popularity and their reputation changed from distinctive to commonplace. In the herbaceous collection, this dahlia is blooming along the lengthy border. Thankfully, she has once more been located! Once more, this lady is the talk of the garden!
Instructions for planting dahlias:
Dahlias can be planted in New Zealand from the middle of August to the end of December, though September or October is the ideal time to do so. Dahlias prefer full sun, so place them in a garden area that receives plenty of sunlight. Ideal sun exposure is at least four hours per day. Dahlias thrive in virtually any type of soil, but they are best in well-drained loamy soil. Several weeks prior to planting, prepare the soil by carefully tilling it, adding some well-rotted compost, and applying general fertilizer.
Before planting, stake the tubers to prevent damage to the roots and tubers
Dahlia tubers should be planted with the eye facing up, 5–10 cm is deep, and 50 cm apart. Water your plants regularly, but don’t water them too much. It’s important to keep an eye out for earwigs and slugs because they can be a real pain when it comes to dahlias. Excellent solutions for controlling slugs and snails, respectively, include slug bait and neem granules.
As soon as the seeds are Planted
If you pinch the plants’ tips after the second set of leaves has appeared, dahlias will grow four flower stalks rather than just one. Although it may seem harsh, you will be rewarded with an abundance of blooms for weeks or even months! Use a sharp knife to cut off the top two pairs of leaves from the main shoot, or squeeze it between your thumb and forefinger. If possible, remove all but five of the shoots that are emerging from the tuber. They should all be removed once there are only five shots left. This will encourage the growth of robust, bushy plants as well as an abundance of blossoms.
Selecting Dahlias:
Because Dahlia Flowers don’t continue to open after being cut, it’s vital to only choose blooms that are fully open when purchasing them. Consider having a deadheading field day once in a while if you don’t get to all of the flowers for the vase. This will not only keep the plant clean but will also extend the flowering period and ensure that more nutrients are returned to the plant’s tubers.
Colorful Dahlias are one of the most popular flowers in the world
As one of the most popular perennial garden plants, dahlias are available in a wide variety of vibrant hues with their own set of floral characteristics and sizes that set them apart. The best conditions for growing dahlias are those with full sun and well-draining soil that is protected from strong winds. Staking the taller types, on the other hand, is a smart idea; some may be grown successfully in appropriately sized containers. It is possible to keep them blooming all summer long with regular deadheading, resulting in a magnificent late autumn show.
After the first cold, they should be cut down to the ground and removed because the stems, which are highly succulent, will turn black, collapse, and allow infections to establish. Because of their underground tubers, dahlias are more susceptible to rotting in the winter. As long as the tubers are in damp sand, you can remove them and divide them for planting in the garden in mid-spring or to give them at this time. For this piece, we photographed one of our most popular dahlias: many visitors stop to inquire about its name. New Zealand Dahlia ‘Longwood Dainty’ was bred and named after the Longwood Ranges, which are located near Riverton in Southland.
The 3 STEPS TO GROWING DAHLIAS
Get ready:
In full sun or some shade, Dahlias will thrive and can be grown if necessary. However, with fewer hours of sunlight, they won’t bloom as well. As long as the soil is fertile, they can grow in a wide range of soils, from sandy to loamy. Once planted, they can withstand dry periods without additional watering, but moist, nutritious soil will help the plants develop faster and provide a longer flowering period.
Be patient if you live in a frosty environment and wait until after the last frost to plant. Do not plant them too early since their new growth is too delicate and tender to withstand frosts. The Cafe au Lait, Copper Queen, Dream Catcher, Edna Brown, Jim’s Passion, Kotare Buttermilk, Mystic series, Rural Belle, Rural Lady, Taratahi Sunrise, Titoki Point, Tranquility, True Love and Twinkle are some of my favorites. The foundation of your garden, like that of a house, is critical to its long-term success. Your plants’ growth will be enhanced if you use high-quality soil. Start by adding organic matter like Tui Sheep Pellets and Tui Compost to your soil if you have an established garden bed. Add a layer of Tui Rose & Shrub Mix, and you’re done.
You can plant dahlias in large pots, but they should be at least 30L in size
Dahlias require lots of space to thrive, so resist the urge to crowd them. When establishing new planting areas, make sure to account for the potential size of your dahlias. If you’re unsure, use the height-spacing system: if your plant grows to a height of one meter, then space them one meter apart. This is the name of the plant. Early in the morning or late in the day is the greatest time to plant because the plants aren’t exposed to the scorching sun right away, which can harm them. Before and after planting, make sure to thoroughly moisten your plants.
The following are the planting instructions for raised garden beds:
Before planting, water the plants thoroughly and allow them to dry out. Your plant’s root ball will require a hole that is twice as deep and wide as it is wide. Position your plant in the center of the hole by gently loosening the root ball. Put the Tui Rose & Shrub Mix in the void. Place your hands carefully around the plant’s base. Dahlias need to be watered regularly and thoroughly.
Potting instructions:
- Allow the soil to dry up before planting.
- Half fill your container with Tui Rose & Shrub Mix.
- Removing dead or loose pant material and roots is necessary before removing the plant from its current pot, so be gentle.
- The plant should be placed in the middle of the new container, and the soil should be filled to a height of 3cm above the soil line.
- The base of the plant should be surrounded by a slightly hard mixture. In this container, the mix should be placed at the same height as it was in the previous one.
- Dahlias need to be watered regularly and thoroughly.
NOURISH:
Your dahlias will repay you with a beautiful summer display if you give them what they need. Your plants will reach their greatest potential if you replenish the nutrients they use. Tui NovaTec® Premium Fertilizer should be used for dahlias in the spring and fall to promote healthy growth and optimal flowering. Insect pests and diseases have a better chance of avoiding a well-watered and well-nourished garden. While dahlias are actively growing, give them a boost with Tui Organic Seaweed Plant Tonic. Between feedings, this can be used as a plant tonic.
