RUSTICA PLUS by Campbells Fertilisers Australia

Slow-release NPKS compound fertiliser with Magnesium, Calcium and Micronutrients.

A dry spread application fertiliser that meets the complete nutritional requirements of vegetables, fruits, vines, flowers, turf and ornamentals. Rustica Plus has been widely used in Australian horticulture for over 40 years.

NUTRIENT FORMS:
Nitrogen is present both as nitrate and ammonium. The readily available nitrate-nitrogen gives an immediate growth response, while the more slowly available ammonium-nitrogen ensures a long-lasting effect.

Potassium is present as sulphate of potash only, which makes the product chloride-free.

Phosphorus is in a soluble form, allowing ready uptake by plant roots and is essential for the establishment and early development.

Secondary Nutrients and Micronutrients are present, with amounts tailored to plant production, with emphasis on calcium, sulphur, magnesium, zinc and boron.

ADVANTAGES:
The specific ratio of nutrients in Rustica Plus is formulated to meet the complete nutritional needs of a vast range of horticultural crops.

Rustica Plus has a low salt index and hence minimises the potential for fertiliser scorch. It is near neutral in its effect on soil pH, which helps maintain a productive soil environment.

Rustica Plus is a true compound fertiliser, not simply a mixture of different fertilisers pressed into a granular form (a granulated blend) or different fertilisers physically mixed together (a blended fertiliser).  The consistent granule size range allows uniform application with no separation of nutrients.

APPLICATION FOR INDOOR PLANTS:
Apply compound pallets sparingly around the base of the plant and water as usual. The fertiliser will be released when watered. Once pallets completely dissolve, re-apply as needed. See the website for more directions before opening.

GENERAL APPLICATION:
Campbells Rustica Plus is ideal as a base or top dressing.  It is a non-dusting, free-flowing product that can be applied as a band or broadcast or can be incorporated into the soil or growing medium prior to planting.

Consistency is the key
This product is amazing. You have to keep in mind that it doesn’t give instant results. However, consistent use will reveal wonders. I use my whole stick before I started to see results. When my stick was gone, is when I looked in the mirror and I was shocked. My forehead was tighter and lifted. My under eye bags had disappeared, and my eyes looked tighter. My skin was just so youthful looking. So I was like OK!! I need to order another one, I swear I didn’t think it was working at all until the sticker was gone. And I just woke up one morning and noticed a huge difference. I wonder if the changes will last?

The balm stick needs to roll all the way to the top
Overall I like the product itself I think its very moisturizing and it does seem to help the appearance of wrinkles however I think for the cost its pretty wasteful in the application. The rollup stops and there is still a ton of product on the bottle. I had to dig it out with my finger for a good 2 weeks worth of product I dont understand why it doesnt roll all the way to the top..

Seems like it provides good coverage
Size: 6 Fl Oz (Pack of 1)
I am very much liking this for the sunscreen properties. It should be noted that your face will be white and it's hard to meld into your natural skin tones. However I'm more concerned with something that works

reliable everyday sunscreen
Size: 6 Fl Oz (Pack of 1)
this product goes on smoother than many mineral sunscreens I’ve tried and doesn’t leave an overly thick or greasy feeling on the skin. The protection lasts well during outdoor activities, and the water resistance makes it great for the beach, workouts, or long walks in the sun.
