Summer-flowering bulbs

About this variety

Dahlia Black Jack is a striking dahlia variety known for its dramatic and elegant dark burgundy to almost black blossoms. With its rich, deep color, this dahlia adds a touch of sophistication and intrigue to gardens and floral arrangements.

Why We Like It

  • Dark and Dramatic: The deep burgundy to black blooms of Black Jack create a bold and captivating focal point in any setting.
  • Late-Summer Beauty: It blooms late in the summer, extending the season of vibrant color in your garden.
  • Versatile in Arrangements: Its dark, luxurious flowers are excellent for creating eye-catching bouquets and floral designs.

What to Know

  • Soil and Sun: Plant in well-drained soil with full sun to partial shade for the best growth and flowering.
  • Watering: Keep the soil consistently moist but not waterlogged, especially during hot and dry periods.
  • Deadheading: Regularly remove spent flowers to encourage continuous blooming and maintain the plant's appearance.
  • Overwintering: In colder climates, dig up tubers before the first frost and store them in a cool, dry place during the winter.
  • Pest Control: Keep an eye out for common garden pests like aphids and caterpillars, and address them as needed.

When to buy and plant

Buy summer-flowering bulbs in spring. Plant according to the variety’s instructions; tender varieties may need to be started under cover and planted out only after frost risk has passed.

Planting and growing

Choose a position and compost suited to the variety. Follow the pack for planting depth, spacing and whether it suits a container or a border.

Aftercare

Water as needed and feed according to the variety’s guidance. Some plants need support. Check whether bulbs or tubers should be lifted, dried and stored frost-free over winter.

Blue Samurai Pacman Frog | Ceratophrys cranwelli

The frog is in good condition and settled in very quickly, having bought frogs here before I was confident that the frog would be healthy and have a head start on learning certain skills (tong feeding). The staff are friendly and made sure to question me to make sure I had everything I needed to properly take care of them in the long term. Excellent service as always

Mixed Daffodils – 2kg Bag
Daffodil bulbs

I am absolutely delighted with the service I have received from Newlands . The Order of various daffodil bulbs were delivered the next day ! How efficient was that! I have begun to plant them to have an early spring display. Each of the bulbs look healthy and not soft as sometimes occurs . I would highly recommend Newland for ordering , fast and protected delivery and competitive prices .
Happy planting !

HabiStat Leopard Gecko Substrate 10kg
Excellent

Tried this substrate out of curiosity. Previously my gecko was on Earth Pro Arid which itself is a good substrate, so I didn't expect it to be outperformed. I prefer this substrate by far. It does not give off any dust when dry. When wet it sticks and holds together like sand on a beach, making it very malleable and easy to landscape your viv. It holds humidity very well. My gecko hates sphagnum moss, so I use this in his humid hide and it works just as good, so it's solved that issue for us!

Everything I ordered came packaged very securely with fragile stickers attached to the outside. Which was appreciated as bulbs were also in my order. Order arrived quickly too!

I am really pleased with the pond plants I purchased from Newlands, it was the first time I had done so. The plants were in good condition, and I have no hesitation buying more plants in the spring for my pond from them.
