Fiddle Leaf Fig Plant Food
How much food should I use on a houseplant? I have 4″ potted plants.
Use 1 teaspoonful diluted in 2 cups of water, and water each week as normal.
How will I know if my plant is getting enough fertilizer? I wish my plant could tell me how it’s feeling!
For optimal growth, fertilize your houseplant every week throughout the year. Read our blog post that discusses this specifically.
What color is the fertilizer?
The fertilizer is a clear liquid with a blue tint.
What’s an NPK ratio and what does it mean for my houseplant?
The abbreviation NPK stands for nitrogen (N), phosphorus (P), and potassium (K), the main nutrients essential for plant growth. We created our Fiddle Leaf Fig Plant Food with the ideal NPK ratio of 3-1-2 to support healthy roots, leaves, and growth in your houseplant.
Can I use this fertilizer on my succulents?
We do not recommend this product for succulents.
How can I learn more about the beautiful fiddle leaf fig plants?
You’ll find a lot of information online, but an essential reference is The Fiddle Leaf Fig Expert: Your Guide to Growing Healthy Ficus Lyrata Plants.
What exactly is root rot?
Root rot is a plant disease that attacks the plant’s root system, and it’s caused by certain water molds and fungi which result from over-watering your plant. The symptoms of root rot include stunted growth, wilting, as well as discolored leaves, which result from the plant’s inability to absorb moisture and nourishment.
I started using the Root Supplement yesterday, but so far nothing is happening. What should I do?
Although Root Supplement should be started at the first sign of disease, it should only be applied every two weeks as directed. The supplement is taken up by the plant’s root and foliar systems, where it then activates a biostimulant response which leads to improved nutrient uptake and assimilation, abiotic stress tolerance, and enhanced natural defense mechanisms. But be patient because this process takes time.
What is the “integrated growing plan” I hear you talk about, and how will it help with my plant’s root rot problem?
To assure your houseplant’s health and vitality, there are several factors involved in the integrated growing plan. For root rot treatment, this might mean using Root Supplement along with repotting, modifying watering intervals, and utilizing a suitable fertilizer.
Can you explain the difference between the phosphite in Root Supplement and regular phosphate in typical fertilizers?
Don’t confuse phosphite supplements with phosphate-derived fertilizers, such as potassium phosphate and those found in traditional fertilizers. Although phosphite and phosphate compounds are chemically very similar, their actions in plants differ significantly. Phosphates are primary sources of phosphorus in plant fertilizers. Phosphorus is essential for all living organisms; plants use it for many processes, including photosynthesis, energy storage, and cell division.
On the other hand, phosphite has one less oxygen than phosphate, which means that it acts in a completely different way than its phosphate counterparts. First of all, plants absorb phosphites more easily, although they contribute little to no phosphorus. However, although phosphites lack nutrient value, they make up for this by simulating the plant’s natural defense mechanisms. And even though phosphites can control root rot disease in plants, they’re unsuitable for phosphate fertilization. The inverse is also true: phosphate is an excellent source of phosphorus for plant growth but is unable to control certain diseases, such as foliar blight, downy mildew, and root rot. Therefore, to produce optimal vitality in your houseplant, a good growth plan should include phosphate fertilizer in addition to a phosphite supplement (such as Root Supplement).
Can I mix Root Supplement with Fiddle Leaf Fig Plant Food?
Yes! These products were designed to be used together, but just be sure to first put water in the container before adding the fertilizer and Root Supplement.
What color is Root Supplement?
Root Supplement is a clear liquid.
How do I use Root Supplement for my plants?
Add 1 teaspoon of Root Supplement to 2 cups of water and apply with normal watering every 2 weeks. We recommend that you use it in addition to fertilizer.
Can I use Root Supplement on all my houseplants, even succulents?
Although you can use Root Supplement on all houseplants, I wouldn’t recommend using it on succulents as they typically don’t suffer from the same root rot organisms.
My houseplant is growing new leaves and getting healthier, but why are the brown spots on the old leaves still there? What’s going on?
Brown spots on leaves will unfortunately never repair themselves. Remove the affected leaves with clean pruning shears. Don’t worry, pruning your houseplant helps encourage new growth!
Even though my houseplant doesn’t have root rot, can I still use Root Supplement as a preventative measure?
Yes! Root Supplement was developed to be used at the first sign of root rot as well as to maintain healthy root systems to prevent root rot.
Premium Indoor Plant Soil
Can I just use regular garden soil for my houseplants?
All plant roots require water, nutrients, and air to survive. In the wild, the soil is constantly replenished with nutrients, aerated by earthworms, and it also has perfect drainage! However, potted houseplants sit in the same soil for months and even years. Every time you water, the soil is compacted, likely won’t drain as well as in the wild, and the nutrients are washed away. This is why it’s critical to have a houseplant soil that is specially formulated (read more here). Our Indoor Plant Soil is created to provide perfect drainage, aeration, and nutrients for your houseplant. Your houseplant with thank you!
How frequently should I repot my indoor houseplants?
We recommend repotting your plants once per year for optimal health and growth. For very large plants, you can top-dress the soil, or remove the top few inches of soil and replace with fresh soil.
What is biochar, and why is it important for soil?
Biochar is a soil amendment that reduces the need for water and fertilizer, because more moisture and nutrients remain in the soil and don’t leach into the groundwater, all of which enhances plant growth. Biochar is created by burning wood and agricultural byproducts slowly, at low temperatures, and with a reduced oxygen supply. Read more about the many beneficial properties of biochar that make it perfect for growing here.
You say your indoor plant soil provides good water drainage, but don’t plants NEED water to survive?
While plants need water to survive, to avoid root rot, the plant’s roots need to dry out between each watering. In fact, root rot caused by the roots sitting in too much water is the most common cause of problems and disease in houseplants. With a fast-draining soil, your plant’s roots will have access to the necessary moisture without the risk of root rot. In our blog post on choosing the best soil for your houseplant, we discuss this in more detail.
Plant Care and Maintenance
There’s dust on the leaves of my indoor houseplants. Should I do something about that?
It is important to keep the leaves of houseplant clean and free of dust. For cleaning tips and more information, read our blog post on this subject.
I’m new to growing houseplants. What would be a good “starter” plant?
How do I know what pot size is best for my houseplant?
To allow for new growth, choose a pot that is 2 to 4 inches larger in diameter than the existing pot.
I know everyone says that over-watering plants is bad, but how much is too much, and how do I tell?
Too much water is the number-one killer of houseplants. We recommend watering once per week, but only if the top inch of soil is dry to the touch.
My houseplant is almost dead, but I’m all out of options. What should I do?
While some houseplants can be too far gone, there still might be hope to save a plant that’s on the brink of death. Read more here.
