Whether you’re planting dahlia bulbs, growing gladiolus, or looking to fill your garden with cheerful violas and lavender, flowers bring beauty, colour and joy to any space. But for long-lasting blooms and strong, healthy plants, it all starts below the surface with the right soil nutrition and biological support.
We’ll cover the benefits of planting spring and summer flowers with Rootella and Superzyme, and how to get the most out of your flower garden, especially if you’re growing bulbs like gladioli and dahlias.
Planning your flower garden
Whether you’re planting in beds, borders or pots, now is the perfect time to focus on soil nutrition and to get started in growing flowers for the warmer months ahead.
Here’s what to consider:
- Dahlia bulbs: Best suited to frost-free areas, dahlias love full sun and rich, well-draining soil.
- Gladiolus: These classic summer flowers are planted as corms and grow tall spikes of colour. Stagger your planting every two weeks for continuous blooms.
- Violas and bellis (English daisy): Compact and colourful, these are ideal for borders or containers and perform well with a bit of morning sun and regular watering.
- Lavender: A pollinator favourite that loves a sunny, open spot with free-draining soil. Avoid overwatering.
Why soil nutrition matters when growing bulbs and flowers
Good soil nutrition is the foundation for healthy flowering plants. Bulbs like gladiolus and dahlia store energy and nutrients in their bulbs, so they need space and a soil environment that allows roots to grow freely to access mineral nutrition, otherwise bulbs diminish in size over time.
Start by supporting your soil with biological inputs that go beyond basic soil nutrition. Products like Rootella and Superzyme help unlock, activate and transport existing nutrients, improving root function and creating a more resilient, active soil environment providing protection from disease.
Rootella supports healthy root growth and nutrient uptake
Rootella contains living mycorrhizal fungi that forms a natural partnership with plant roots, extending their reach and helping them absorb more water and nutrients, especially phosphorus, which is vital for flower, bulb and root development.
When planting your dahlia bulbs, or bulbs of any type, apply Rootella directly into the planting hole or mix it into the soil or potting mix. This small step can result in:
- Faster establishment and growth
- Stronger flowering
- Improved drought resilience
- Better nutrient efficiency
Superzyme activates life in the soil
Superzyme is a biological product packed with living beneficial bacteria and fungi. It boosts microbial life in the soil and supports root activity, which is ideal when you’re growing bulbs in regularly used garden beds or starting a new patch.
Use Superzyme at planting and again as a foliar or soil drench every few weeks. Gardeners report healthier foliage, more consistent flowering and improved resistance to pests and disease stress.
Quick flower tips for home gardeners
- Soak bulbs for an hour before planting in a small quantity of Mobilizer with water to hydrate and encourage quicker sprouting
- Plant gladiolus corms 10 to 15 cm deep and space them about 10 cm apart
- Feed regularly, but lightly, especially when using biological inputs
- Apply mulch to retain moisture, but leave a gap around bulbs to prevent rot
- Remove spent flowers to promote continuous blooming throughout the season
Healthy roots, happy blooms
Whether you’re planting cheerful violas, elegant gladiolus, or show-stopping dahlias, vibrant flowers begin with strong roots. Using biological inputs like Rootella and Superzyme helps build a healthier soil environment, giving your plants the foundation they need for colour, strength and lasting growth.
