What is Bur ka potato and why do people use it?

Bur ka potato usually refers to leftover potato water or mashed raw potatoes used for plants. People believe that potatoes contain starch and nutrients that can naturally nourish plants. This idea spread rapidly on social media because it seems easy and free, especially for home gardeners.  


Some even believe that Bur ka potato helps weak plants recover quickly. Because potatoes are a living food, many assume it will be good for the soil as well. But plants don't eat like humans. What goes into the soil matters a lot.

What's actually in potatoes for plants?

Potatoes mainly contain starch, some potassium, and small amounts of minerals. These nutrients are locked inside organic matter. Plants can never directly absorb solid starch through their roots. Soil microbes have to break it down first, which takes a long time.


If your soil is healthy and alive, a small amount of organic matter can slowly help. But in indoor pots, soil life is limited. Therefore, most of the time, potatoes don't become plant food as quickly as people expect.


When can potato water help?

Potato water can offer some benefit if used in a very diluted form. For example, unsalted, cooled boiled potato water can be mixed with water containing a small amount of organic matter. Over time, this can support soil microbes, rather than directly feeding the plant.


This works better for outdoor plants where there is a larger volume of soil and good drainage. In indoor pots, the effect is much slower and often imperceptible. This is why many people find the results inconsistent.


When can potato water harm your plants?

Using raw potato pieces or concentrated potato water can cause serious problems. It can rot in the soil and attract fungus, ants, or cause unpleasant odors. Indoor plants are especially susceptible to poor soil conditions.


Many people see yellowing leaves or fungus after using potatoes and think the plant is weak. But in reality, the soil is compromised. Once soil health is damaged, it takes time and patience to recover.


Common Mistakes vs Safe Practices

MistakeBetter Fix
Adding raw potato piecesUse only diluted, cooled water
Using potato water weeklyLimit to once a month
Expecting fast growthThink long-term soil support
Using in small potsAvoid for small indoor pots


Better Natural Alternatives to Potatoes

If you want safe, homemade options, there are even better alternatives. Things like vermicompost, cow manure compost, or diluted compost tea work more reliably. They are already broken down and easier for plants to absorb.

Even simple things like providing the right light, proper watering, and clean soil are more beneficial than kitchen remedies. Fertilizer is only a small part of plant care, not the complete solution.

How I personally use it (if I do)

Personally, I avoid using potatoes for my indoor plants. If I ever do use it, I always test it on an outdoor plant first. I dilute it heavily and observe it for two weeks. Most of the time, I don't see any significant changes.


This has taught me that patience and consistency matter more than viral hacks. Plants don't need experiments every week. They need consistent care and a calm routine.


Final thoughts

Potatoes are not a miracle cure for plants. At best, they provide a mild organic boost when used very carefully. At worst, they can harm the soil and attract pests. For indoor plants, simple fertilizer, good light, and proper watering work far better. Gardening is slow, gentle, and honest – just like healthy plant growth should be.

What is potato water for plants and how does it work?
Potato water refers to the cooled leftover water from boiling potatoes. It contains nutrients such as potassium, phosphorus, and minerals that soil microbes can break down and make available to plants when used correctly.
Can I use boiled potato water to water my plants?
Yes — if the water is unsalted, fully cooled, and diluted, it can be used as a mild fertilizer because it provides micronutrients that help soil life, but it should not replace regular watering routines.
Does potato water really help plants grow faster?
Potato water can support plant growth by feeding beneficial microbes and adding potassium, but it is not a quick growth miracle. Benefits are gradual and most noticeable when soil is healthy.
Which plants benefit most from potato water?
Deep-rooted, nutrient-loving plants like tomatoes, peppers, or flowering houseplants may benefit most. Shallow-rooted plants (e.g., cacti or succulents) are best avoided with potato water due to potential sogginess.
How often should I use potato water on my plants?
Use potato water infrequently — typically once every 2–4 weeks during active growth periods — to avoid soil imbalance, mold, or root stress.
Can potato water harm my plants?
Yes — if it contains salt, seasonings, or is not diluted, it can harm plants by causing nutrient imbalance or soil salt buildup and attract pests or fungus.
Should you add raw potato pieces to potting soil?
No. Raw potato pieces can rot, invite pests, and create fungal issues in the soil rather than directly feed plants. Always use only the strained water.
Is potato water a substitute for fertilizer?
No. Potato water provides trace nutrients but lacks a balanced nutrient profile (NPK) that plant fertilizers provide. It should only be a supplement to regular fertilization.
Can I store potato water before using it on plants?
Yes — once cooled and strained, potato water can be stored up to one week refrigerated but must be shaken and used before microbes start degrading it.
When should I never use potato water for plants?
Avoid using potato water right after boiling with salt, seasonings, or when soil is waterlogged, as this can stress plant roots and harm soil structure.
