- Perennials and Roses: Supports consistent flowering cycles throughout the entire summer.
Instructions and Dosage
For optimal horticultural performance, prepare your solution according to these recommendations:
- Outdoor flowering plants: Dissolve 5 ml (1 tsp) of fertilizer in 2 litres of water. Apply at the base of the plants every 2 weeks.
- Indoor flowering plants: Dissolve 5 ml (1 tsp) of fertilizer in 4 litres of water. Apply at the base of the plants every 4 weeks.
Application:
- Water the soil directly until well-soaked to ensure the solution reaches the roots.
- Avoid applying the solution to the foliage during periods of direct, intense sunlight.
- For best results, fertilize when the soil is already slightly damp.
Botanix Expert Tips
- Consistency: Plants in planters require steady fertilization; mark your calendar to ensure you never miss your bi-weekly application!
- Alternation: For general maintenance, you can alternate with our 20-20-20 formula once a month to maintain overall plant health.
Understanding the Formulation (N-P-K Analysis)
The 15-30-15 ratio is the gold standard for flower production:
- Nitrogen (15): Maintains healthy green foliage to support photosynthesis.
- Phosphorus (30): The key element (double dose) to trigger a massive production of flowers.
- Potassium (15): Ensures stem strength and the overall resistance of the plant.

The Perfected Muscle T-Shirt.
Size: Medium, Color: Black, Size: Medium, Color: Black
This is a great muscle shirt that can be worn many ways.
My grandson likes it for workouts because the gym (or place) is cold, and this muscle shirt is breathable, comfortable, and stretchy, and doesn't restrict his movements. He also likes that it's a little longer than most muscle shirts.
But he also loves how good it feels under sweatshirts because it is soft on the skin and doesn't create bulkiness. The color is a true black and it runs slightly big. The length of the sleeves is just right for his long arms. All combined, this shirt is a fantastic value.

Surprisingly good quality and cut.
Considering that this brand tends to be a bit hit-or-miss (mostly hit) I was apprehensive about the fit and sizing. These fit so well that I bought other colours and have no issue with the sleeve length (often cheaper brands have very short sleeves) nor with the length of the body of the shirt.
They look great, the fabric quality is excellent, and the colours are compatible with a broad range of pants (you can't go past black pants, black jacket/blazer, and any colour of this underneath).

Nice feel
Special Size: Two Pack, Size: Medium, Color: A-wine Red/Dark Grey
I’m 5’8”, trim and athletic build. The sleeves are a tiny bit tight and would be unpleasant on a warmer than expected day, but for a cool day just fine. Nice fit. Feels pleasant to the touch.

Good fit, light weight, very comfortable
Special Size: Two Pack, Size: X-Large, Color: Black/Army Green
I've purchased several of these now and overall they seem like a decent buy for the price. They are very light weight and seem to retain their shape and avoid wrinkling when hung to dry after washing. Despite never seeing a clothes dryer however, the black variant still pilled up a bit after moderate use.
There seems to be some variation in sizing: all the black and olive colored ones seem pretty consistent but the gray run small and the blue just a bit large (all purchased in XL, me at 6'3 and 225#)

Great with a great price
Special Size: Two Pack, Size: X-Large, Color: A-blue/Army Green
First off. I am female 5’10”. I thought the extra large fit great. The material is very soft and light. I think they’re warm though. I just washed them for the first time yesterday with dryer. Air dry. I’d like to see after a couple washes and know how the dryer affects it.
