What To Look In The Best Fertilizer For Indoor Plants
What is the best fertilizer for indoor plants? It is the one you can find easily, use it and get amazing results. For that, you need factors or parameters we actually use while testing the aforementioned products. Now, we will share them with you and hopefully help you in finding the best choice.
Type of a fertilizer
Best organic fertilizer for vegetables varies these days and we can see three main types. Each one has its own list of pros and cons and each one is applied separately. Let’s explain to them.
- Spikes or tablets
Spikes or tablets will be inserted into the soil, next to a plant. Once done, they will start dissolving and providing nutrients. However, they must be replaced at a precise time, as specified on the box.
It is the oldest type and still one of more preferable. It is the best option when you are planting plants into the pots. The nutrients will be absorbed slowly. Just the way plants like it. However, for indoor purposes, this may be paired with a bad odor.
This fertilizer will be mixed with water and then applied to the plants. A good side is simplicity and the fact you have precise control on how much fertilizer you have applied. A bad thing is that you must not forget to add it to the water, and you must follow the specific rules.
A fertilizer that is certified tells you a lot of things. First of all, it is safe for plants. Secondly, it contains all the nutrients as advertised and it is a great option for the plant it is made for. For organic fertilizers, this also means that they do not contain harmful chemicals or any artificial compound. The same applies to the best potting soil for herbs.
Nutrients inside (numbers on a bag)
You may have seen an NPK on the plants and then three numbers. The example is 15-4-8. The NPK stands for nitrogen, phosphorus, and potassium (its symbol is the letter K). What this simply means is that there is 15% nitrogen, 4% of phosphorus, and obviously 8% of K or potassium. Plants need all three minerals but you can choose which variation to get.
Ideally, you will conduct a soil test. Then you will use the best natural fertilizers for that soil, which contain nutrients that are depleted in the soil.
Size of a package
More plants need more fertilizer, so you will need a larger package. We believe that getting a larger package instantly is a much better option than getting a smaller one and then adding a second package. By using this trick, you will make sure that the plants don’t stay without nutrients at any given moment.
Are you looking for the best organic fertilizer for tomatoes or some other plant? Most fertilizers come in multiple options. Some are made for generic purposes, while others are made for a specific plant type. Consider this and try not to make a mistake.
- What is fertilizer?
Fertilizer is a set of vitamins and nutrients plants need. It is equivalent to multivitamin tablets people can take. It is essential for the proper growth of the plants and better health.
- What NPK stands for?
NPK refers to nitrogen, phosphorus, and potassium. The number next to it refers to the percentage of these ingredients in the fertilizer. For example, nitrogen makes the plants green, phosphorus boosts the root growth while potassium keeps plants immune to diseases.
- Is a soil test needed?
Yes and no. If you are in a hurry, you can get any fertilizer for the plant you have. But, if you want to do it properly, you will need to conduct a test of the soil, find which nutrients are lacking and get fertilizer, which is rich in those nutrients specifically. Add the best organic potting soil to the equation and you will get the best results.
- Do all plants need fertilizer?
Yes, all plants do need fertilizer but of different types and at different times of a year. You will need the best fertilizer for raspberries, the best for vegetable and the best for flowers to get the biggest and healthiest plants.
- How often do I need to add fertilizer to the plants?
The time frame will be specified on the box. Some fertilizers need to be added every week. Others need to be added after 60 days during winter and after 30 days during summer. In general, liquid fertilizers need to be added sooner, while spikes and tablets need to be replaced after a longer period of time.
- Do outdoor plants need fertilizer as well?
Yes, outdoor plants do need fertilizer as well. However, in this case, scenario we do not recommend pills and spikes. They are ideal for small plants in a controlled environment. For outdoor purposes, we recommend liquid or granular fertilizers.
- Can fertilizer burn the plant?
Usually, this isn’t the issue. However, if you apply too much fertilizer to a plant, you can kill it. Always follow the instructions on the box. Adding too much fertilizer won’t have any positive effect on the plant.
What is the best fertilizer for indoor plants? Our answer is Miracle-Gro Water Soluble All Purpose Plant Food. Reasons are easy to apply to the plants, offers all major nutrients, and can be used on all plants. It is a safe, reliable, and effective method to boost the health and productivity of your plants.
