Lorem Ipsumis simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it

TOPBUXUS Health-Mix is designed to strengthen buxus plants, providing essential nutrients through foliar spraying application.

The nutrients are absorbed directly by the leaves, starting to work in just 15 minutes. It bypasses root competition in instances of closely planted dense root systems so that each plant gets the nutrients it needs. It neutralises water pH to improve nutrient intake.

Can Topbuxus be used on other types of hedges?

Yes, Topbuxus products can be used on all types of hedges, particulary ones that are box like. Euonymous, Japanese yew, Illex etc. They're beneficial to a wide variety of plants such as Pittosporum, Japanese box, Viburnum, and Lilly Pilly. They're also safe around other plants and contribute secondary nutrients. For more guidance, see our YouTube channel: Topbuxus Garden Care.

How do I treat root disease?

Use a combination of anaerobic microbes, and mychorrizal funghi (trichoderma) along with Topbuxus Health-Mix every 4 weeks. Once the disease improves, apply Topbuxus Grow every 6–8 weeks. Continue until noticeable plant recovery.

Why are my buxus turning brown?

Browning can result from stress, disease, poor nutrition, or watering issues. Prune dead areas, ensure soil is healthy, and alternate between Grow (every 6–8 weeks) and Health-Mix (every 4 weeks). Make sure you contact a local horticulturalist if you are unable to correctly identify the cause.

How can I treat blight?

Apply Topbuxus Health-Mix then again two weeks later to beat the spore proliferation cycle, then apply monthly. Prune damaged areas and sanitise tools. Ensure good irrigation and soil aeration. Avoid working on frosty days.

Why are my long-established hedges struggling?

Stress usually is caused by either, too frequent, infrequent and irregular watering, lack of the right nutrients, soil quality and sunlight issues. Older hedges that are sizable will naturally need more nutrients to thrive. Often the plants have taken all of the available nutrients from the soil and require adding more nutrients to begin recovering. In the instance of potted Buxus, they may have simply out grown the pot and require replacing into a pot size that fits the size of the root system and plant.

How do I get rid of mealybugs?

Use eco-oil or introduce ladybugs as a natural predator. Maintain consistent Grow and Health-Mix applications. See YouTube for guidance.

When is the best time of year to fertilise my Buxus?

Most Buxus benefit from feeding in early spring and again in late summer. In warmer climates, feeding can continue later into the year. The best sign to fertilise is at the sign of new buds which follows a 6-8 week cycle from the beginning of Spring.

Should I prune before or after applying fertiliser?

It’s best to prune first, then apply fertiliser to support recovery and stimulate fresh growth. This is because plants require energy from nutrients to recover. The more you prune, the more energy the plant will need to regrow what has been clipped.

How soon will I see results after using Topbuxus products?

Health-Mix may show results within 72 hours. Full recovery and improved appearance typically develop over 2 to 4 weeks.

Can I use Topbuxus products in hot or cold weather?

Avoid using during extreme heat (above 32°C) or frosty conditions. Milder mornings or evenings are ideal for application.

Will Topbuxus help with pest prevention?

Topbuxus products can help against perst prevention through developing better and stronger quality growth. It reduces the likelihood of stress related pests from lack of nutrition, and will also boost the recovery. Topbuxus products are not direct pest management products (aside from Topbuxus Anti-caterpillar)

Do Topbuxus products work in poor soil?

Yes, the nutrients support plants even in poor or compacted soil, especially when paired with improved watering and aeration.

How can I keep hedges healthy without excessive height growth?

Regular pruning is the key to managing the height of your hedges. Consistent clipping should keep them closer to the height that you require. However, as hedges grow, they will naturally increase in size and may require hard cut backs or renovations, to keep them at your desired height. If you are doing a hard cut back or renovating ensure you apply Topbuxus Health-mix and Grow to ensure that all plant wounds are innoculated and that enough nutrients are supplied to boost energy stores for a faster recovery.

Can I overuse my fertiliser? Can I get an SDS?

No risk of overuse. SDS documents are available upon request. Grow and Health-Mix are based on natural components and include essential nutrients like Calcium, Sulphur, and Magnesium.

What are the ingredients in your fertilisers?

Health-Mix: NPK 8-0-10 + Magnesium, Sulphur, Copper. Grow: NPK 13-3-13 + Magnesium, Sulphur, Calcium.

My granules became powder. Can I still use them?

Yes. As Grow is a fast release fertiliser it is designed to break down rapidly in the presence of moisture. Environmental factors like heat and humidity may break them down, but they remain effective. Use the same quantities.

Which products should I use if my hedges are struggling?

Use both Grow and Health-Mix together initially, then alternate (Grow every 6–8 weeks, Health-Mix every 4 weeks).

Can I overapply either Grow or Health-mix

You can't over apply as the products have been designed to be safe with over application. However, we advise using as directed for best results.

My sprayer isn't working. What should I do?

Please send a video of the issue so our team can assist you directly.

Can I use Grow and Health-Mix together (AU orders)?

Yes, start with both, then alternate: Grow every 6–8 weeks, Health-Mix every 4 weeks.

Can I use Grow and Health-mix together?

Yes, use both together initially, then alternate applications for optimal results.

Can I water after spraying Health-Mix?

Yes, but wait a few hours before watering stems or foliage. Watering soil immediately is fine.

How do I prepare my buxus for winter in a cold/wet climate?

Use both Grow and Health-Mix. Apply Grow in late Autumn/Winter for root health. Avoid applying Health-Mix during frost; wait for warmer conditions. It is also best not to prune too late into Autumn as you want the leaves to mature and harden off so they are less susceptible to damage. In high frost/snow ares, it can be benficial to cover with burlap or hessian sheets to prevent branches breaking from snow build up.

What is the shelf life of Topbuxus products?

Our products don't have a total shelf life. However Topbuxus Health-mix tablets may break down and lose form after 3 years.

Can I mix Topbuxus with other brands’ products?

Topbuxus is generally safe to mix with other off the shelf pest and disease products. However, we recommend checking to ensure there are no interactions. Grow and Health-Mix are specifically formulated to work together safely.

Are Topbuxus products pet and child safe?

Yes, when used as directed. They’re based on natural ingredients. Keep pets and children away until the product has dried or absorbed.

Are Topbuxus products safe for edible plants?

Topbuxus is designed for ornamental use. While not harmful, they’re not intended for edible plant treatment.

Why do my leaves have a white residue after spraying Health-Mix?

That’s normal. It indicates proper coverage and will fade naturally. It’s not harmful to the plant.

Can I use a regular sprayer with Health-Mix?

Yes, any fine mist sprayer will do, but our battery sprayers provide more consistent and efficient coverage and are designed to optimally distribute the product.
