Gardening in New Zealand offers a rewarding experience, but it also comes with challenges, especially with pests like beetles. These insects can destroy plants overnight and reduce the photosynthetic capacity by %60 if you're talking about 'Bronze Beetle.


Fish fertilizer combined with Naturally Neem is a potent combination! Watch as the beetles back away from your garden; they literally change route on the spot.

Meanwhile, the huge benefits of this NZ-made Fish Fertiliser has for its ability to nourish plants naturally, while Naturally Neem defends and boosts the plant's own ability to protect itself. This post explores how these two products work together to support healthy gardens and keep common New Zealand beetles at bay.

Understanding the New Fish Fertilizer


Fish fertilizer is made from processed fish parts, rich in nutrients like nitrogen, phosphorus, and potassium. The SeaCliff Organics available now in my shop is specially formulated to provide a balanced nutrient boost to plants without harsh chemicals. Here’s how it benefits your garden:


  • Improves soil health by adding organic matter and beneficial microbes.

  • Promotes strong root growth and vibrant foliage.

  • Supports flowering and fruiting by supplying essential nutrients.

  • Safe for all types of plants, including vegetables, flowers, and shrubs.


Unlike synthetic fertilizers, fish fertilizer breaks down slowly, releasing nutrients over time. This slow release reduces the risk of nutrient burn and helps maintain steady plant growth.


How Naturally Neem Works to Deter Beetles


Naturally Neem is derived from the neem tree, known for its natural insect-repelling properties. It contains azadirachtin, a compound that disrupts the life cycle of many garden pests, including beetles. Here’s why Naturally Neem is effective:


  • Repels adult beetles by making plants less attractive.

  • Interrupts beetle larvae development, reducing future infestations.

  • Safe for beneficial insects like bees and ladybugs.

  • Non-toxic to humans and pets when used as directed.


Using Naturally Neem regularly can deter beetles populations without harming your garden’s ecosystem.


Common Beetles in New Zealand Gardens This Time of Year


During the warmer months, several beetle species become active in New Zealand gardens. Knowing which beetles to watch for helps gardeners take timely action.


  • Raspberry Beetle: Attacks raspberry and blackberry fruits, causing damage and rot.

  • Christmas Beetle: Large, shiny beetles that feed on leaves of native trees and garden plants.

  • Lily Beetle: Bright red beetles that chew on lily leaves and flowers.

  • Argentine Stem Weevil: Targets grass and turf, causing yellow patches and thinning.

  • Flea Beetle: Small beetles that create tiny holes in vegetable leaves, especially brassicas.


These beetles can reduce plant health and yield if left unchecked.


Combining Fish Fertilizer and Naturally Neem for Best Results


Using the new fish fertilizer alongside Naturally Neem creates a powerful combination for garden health and pest control.


  • Fish fertilizer strengthens plants, making them more resilient to pest damage.

  • Naturally Neem keeps beetles away, reducing the need for harsh chemical pesticides.

  • Both products are organic and safe, supporting sustainable gardening practices.

  • Regular application encourages a balanced garden ecosystem, promoting beneficial insects and soil life.


For example, applying fish fertilizer every 3-4 weeks during the growing season helps maintain nutrient levels. Naturally Neem can be sprayed every 7-14 days on affected plants to deter beetles effectively.


Practical Tips for Using Fish Fertilizer and Naturally Neem


To get the most from these products, follow these guidelines:


  • Apply fish fertilizer early in the morning or late afternoon to avoid leaf burn.

  • Dilute fish fertilizer according to package instructions for safe use on all plants.

  • Spray Naturally Neem on both sides of leaves, focusing on areas where beetles are active.

  • Repeat Naturally Neem applications after rain to maintain effectiveness.

  • Monitor your garden regularly for signs of beetle damage or pest activity.


Real Garden Success Stories


Many New Zealand gardeners have reported positive results using this combination. One gardener in Auckland shared how their vegetable patch thrived after switching to fish fertilizer and using Naturally Neem to control flea beetles. Their brassicas showed fewer holes and stronger growth compared to previous seasons.


Another gardener in Wellington noted a significant drop in lily beetle damage after applying Naturally Neem weekly, while their flowering plants flourished with the added nutrients from fish fertilizer.


Environmental Benefits of Using Natural Products


Choosing fish fertilizer and Naturally Neem supports the environment in several ways:


  • Reduces chemical runoff into waterways, protecting aquatic life.

  • Encourages biodiversity by preserving beneficial insects and soil organisms.

  • Improves soil structure through organic matter addition.



So, head over to the shop and buy some :)
