Nitrogen helps produce green leaves and stems, phosphorus helps produce root development, and potassium helps the plant withstand stress from heat or cold. A good all-purpose fertilizer would be a 10-10-10 NPK (nitrogen, phosphorus, and potassium). This type of fertilizer will work well for most plants and soil types.
The best fertilizer for any garden is always compost. Compost provides a large variety of material that your plants can use to grow and stay health. It is slow release so it never burns your plants.
A 10-10-10 fertilizer is also called an all-purpose fertilizer because it can be used on almost any outdoor plant, including vegetables, shrubs, trees, flowers, lawns, and houseplants. Generally, it can be applied to any plant that doesn't need higher amounts of one of the three macronutrients.
Chemicals like Miracle-Gro urea-based fertilizer have since been found to kill soil microbes and cause loads of other problems in the environment and human health.
Organic Based Fertilisers
Organic-based fertilisers come from things that were once living. Examples include animal manures (composted poo/faeces), blood and bone meal, fish meal, and green manure crops. Organic-based fertilisers are highly recommended because they add nutrients and improve the soil at the same time.
After weeks of giving each plant different liquids(water, carbonated water, mango juice and pineapple soda), the conclusion is carbonated water grows plants the fastest and the healthiest.
As opposed to Miracle-Gro which offers synthetic NPK (Nitrogen - N, Phosphorus - P & Potassium - K) and little else, Neptune's Harvest products, made from fresh North Atlantic fish, contain vitamins, micro and macro nutrients, amino acids, and natural growth hormones.
Miracle-Gro Has No Place in an Organic Garden
If you want to grow an organic garden, you should never use synthetic fertilizers. These are simply products that contain nutrients made in a lab instead of found in nature.
MG is so strong that if used incorrectly, the fertilizer will actually burn the leaves and roots of your plants (you may have already experienced this). Imagine what it's doing to the healthy bacteria, fungi and other soil microbes that are working so hard to provide the nutrients your plants need.
Nitrogen Fertilizers
Nitrogen is one of the most common fertilizers used in wide farming. Nitrogen is one of the primary macronutrients for plant growth and is essential for forming proteins, chlorophyll, and other important plant compounds.
Best case scenario, this is the standard schedule your lawn needs: Mid to end of APRIL – spring fertilizer – 32-0-6 slow release (fast acting) Early to mid JUNE (6 weeks later) – early summer fertilizer – 25-0-5 – 50% slow release. Mid to late JULY (6 weeks later) – late summer fertilizer – 25-0-5 – 50% slow release.
From a nursery production standpoint, N, P, and K are the nutrients that often need to be applied as fertilizer for optimum plant growth in the field. For plants grown in container media, the secondary macronutrients and some micronutrients can also be limiting to plant growth if not supplied in adequate amounts.
Pinching. Pinch out the growing tip on flowering plants—annuals and perennials. When you remove the tip, the next set of buds on the stem awakens, and two new shoots start to grow. By pinching out the tip, you get twice as many growing stems, which means twice as many flowers.
High-nitrogen fertilizers are known for causing huge growth in plants, which is why many types are rich in nitrogen or include it as the main component. Fertilizers high in nitrogen will also restore bright green hues to your foliage.
Choose Your Feeding Style
Measure and mix it directly into your watering can and pour the solution around the bases of your plants, or use with your hose in a sprayer (like the Miracle-Gro® Garden Feeder) for larger areas. Plan to feed every 7 to 14 days.
When planting tomatoes in a raised bed, use a 50-50 blend of garden soil and potting mix, or 100 percent organic Miracle-Gro® Performance Organics® Raised Bed Mix.
While the basic peat moss, pine bark and perlite type potting mixes will work fine for almost all annual flowers and mixed potted plants, there are some crops for which specialty mixes might be helpful. The most common is potting mix for orchids.
OK, when you use vinegar as a plant disease control you do use a lower concentration which shouldn't hurt the plant. But vinegar has never proven to be particularly effective at controlling plant diseases. Vinegar as a fertilizer: Nope, doesn't work.
Don't just pour it down the drain — you can use it to fertilize your plants, both indoor and outdoor. Coffee grounds (and brewed coffee) are a source of nitrogen for plants, producing healthy green growth and strong stems. Coffee also contains calcium and magnesium — both of which are beneficial to plant health.
