31 Aug How to Choose the Right Fertilizer
#asmallorange Drew Caplan velcrodogdesigns.com – At first these guys were great but a recent string of downtime, lack of support and flat out dishonesty led me to move away. Be warned, you will be let down by this company. Their uptime is terrible, chat waits times long and unhelpful and absolutely no phone support. They recently deleted all of the comments from their Facebook page to hide their unhappy customers.
CORRECTION: Roger misstates the functions of Potassium and Posphorous in this video. Potassium helps with chemical reactions and Phosphorous helps with root growth.

1. A soil test will determine what nutrients are lacking in your soil and need to be augmented.
2. Follow all manufacturer’s instructions to ensure plants are overly fertilized and susceptible to burning.
3. The three main nutrients a plant needs are Nitrogen, Phosphorous, and Potassium, and these are noted as ratios on fertilizer containers.
4. Nitrogen-heavy fertilizers encourage green top growth on lawns.
5. Phosphorous-heavy fertilizers help with root growth (this is mis-stated in the video).
6. Potassium-heavy fertilizers help with chemical reactions (this is mis-stated in the video).
7. Liquid based fertilizers are good for establishing planters like a window box because they work quickly, then a granular slow-release fertilizer can be used over time.
8. Organic fertilizers have less nutrient density and are better for slow release applications like trees and shrubs.
Fertilizer can be found at garden centers or home centers.
