12 best plant root stimulator

A plant root stimulator is a type of gardening product designed to encourage the development and growth of plant roots. It is typically used during the planting or transplanting of plants to support root establishment and overall plant health. Root stimulators contain specific nutrients, hormones, or beneficial microorganisms that facilitate root growth and enhance the plant's ability to absorb nutrients and water from the soil.

Key features and functions of plant root stimulators include:

  1. Root Growth Promotion: Root stimulators often contain auxins, a type of plant hormone that promotes root development and elongation. These hormones encourage the growth of new roots, enabling plants to establish themselves more effectively.

  2. Nutrient Boost: Many root stimulators provide essential nutrients like phosphorus and potassium, crucial for root growth and overall plant vitality. These nutrients aid in the formation of a healthy root system.

  3. Microbial Support: Some root stimulators incorporate beneficial microorganisms like mycorrhizae or bacteria, which form symbiotic relationships with plant roots. These microorganisms enhance nutrient uptake and improve soil structure, contributing to robust root systems.

  4. Reduced Transplant Shock: When transplanting or repotting plants, the shock of being moved can stress the plant and hinder root development.Root stimulators can help alleviate this stress and support faster recovery by promoting vigorous root growth.

  5. Easy Application: Root stimulators are usually available in liquid or powder form for convenient and easy application. They can be mixed with water and applied directly to the soil or used to soak the plant's root ball before planting.

  6. Water Absorption: Some root stimulators contain ingredients that aid in water absorption and retention, ensuring that the roots have adequate moisture for growth and development.

Gardeners use plant root stimulators to enhance the success of transplanting, encourage healthier root systems, and ultimately promote vigorous plant growth. It's important to follow the manufacturer's instructions for application and dosage to achieve the best results.

User questions & answers

Question: What square footage would this bottle cover if spraying the outside of a building
Answer: I have used it at all times of the day although I usually use it in the morning before noon.Just a preference on my part do not think it makes any difference at what time its used.
Question: Can this be used for cuttings to root in water
Answer: I guess like any other spray bottle. I don't remember having a problem, however, if in doubt, I usually rotate the head in a counter clockwise motion, which usually does the trick. I've used this for years without a problem.
Question: How do you use it? On a daily basis or once in a while? Thanks in advance
Answer: It came one piece but you will adjust some part .
Question: no instructions on the bottle I purchased. Please provide instructions/portions, on application
Answer: It doesn't roll well on carpet, but my granddaughter is only five months old. I'm sure an older baby would be able to move about easier.

User questions & answers

Question: Can this be used on tree clipping
Answer: I'm not sure...We used it when we had a huge palm tree planted in our backyard. The palm went into SHOCK and it looked dead for about 2 months. We were told by the nursery to just hang in there...we did, and it is coming back. That is my only experience with it -- but I have to say it appears to be some pretty great stuff!
Question: Would it be appropriate to apply this to freshly planted holly & fraser fir trees in december in western nc with freezing temperatures
Answer: I bought it to stimulate slips of geraniums in California. It worked fabulous! But no idea regarding your question. Good luck. Maybe the manufacturer can answer your question.
Question: I'm new to planting trees and bought a crabapple tree. Is this product good for it and is it all I would need
Answer: The Root Stimulator is an excellent product for new trees. The stimulator should do the trick to plant it but you'll need to spray it in the spring every year for any diseases and bugs that might want to munch on your tree, keep that in mind.
Question: Would this be good for a tree planted about 2 weeks ago
Answer: Absolutely. I use the Root stimulator every time I plant a tree or shrub. It has a mild fertilizer, vitamin B1, and a rooting hormone in it to encourage quick root development after planting and to help with transplant shock. It's a great product. Water your newly planted tree or shrub with Root Stimulator every time it needs watering for the first 2-3 waterings after transplant. You can still use it now and have very good results. Thanks!

User questions & answers

Question: How do you apply this product? do you mix it and spray it on? Do you pour it around the roots
Answer: I mix it with water and pour it around the roots.
Question: I've read this product is not for edible plants. Why are people suggesting it for their vegetables? Is it not really toxic
Answer: I’ve used it for over 40 years on my vegetables and everything else that I’ve planted.
Question: How much per gallon should I use and how much of that gallon should I put on a small tree just planted
Answer: Mix root stimulator at a rate of 3 1/2 tablespoons of root stimulator product to 1 gallon of water or for treating many new plants, mix at a rate of 1 pint of root stimulator to 1 gallon of water. Pour the diluted root stimulator solution around the root zone of new transplants. Pour the solution on the soil and not directly on the plant stems and leaves. Apply 1 pint of solution per plant for small plants, such as annual flowers, up to 1 foot tall. Use 3 pints of root stimulator solution per plant for plants 1 to 4 feet tall. Use 1 gallon of the root stimulator solution per plant for plants over 4 feet tall. If you are treating a potted plant, apply 1/2 cup of the solution for each quart of soil in the container. For example, a 2-gallon container holds 8 quarts of soil, so you apply 4 cups of root stimulator solution to the container. Reapply new root stimulator solution once every two weeks for the first six months after transplanting. If a plant that was 6 inches at planting time, requiring 1 pint of root stimulator solution, grows to 2 feet tall after a few months, increase the amount of solution to 3 pints per application.
Question: what is the mineral ratio of this fertilizer? I.e., nitrogen, etc
Answer: This is a 4-10-3 fertilizer with nitrogen 4%, phosphate10%, Soluble potash 3%. Don't know if you are familiar with this product, but I have used this stuff for years on everything I plant whether it's for outside plants or indoor plants. The nursery where we use to live carried this and we recently moved where I can't find it. So I ordered it on line at actually a cheaper price and larger quantity than I was use to. It absolutely is the best for new plants. And no, I don't have any affiliation with ferti-lome...Luther

Super Charged Moon Juice Tree and Plant Root Stimulator 1 Quart

Based on 28 reviews Check latest price

Product description

Tree & Plant Health Maximizer Our Supercharged Moon Juice is designed to maximize the nutrient intake and growth potential of all trees, palms, and plants. Tree and plant growth cycles are regulated by environmental signals. The Furst liquid technologies that Supercharged Moon Juice uses include a proprietary blend of organic enzymes and amino acids to stimulate the growth signals within the plant. One of the many benefits of Supercharged Moon Juice includes new root hair growth. This provides the essential nutrients needed to increase fertilizer and moisture intake. It also provides stronger cell development throughout the trunks, branches, and stems which allows water and nutrients to pass more efficiently to the leaves. Within the foliage, these stronger cells help maximize photosynthesis and optimize the evapotranspiration rate. Supercharged Moon Juice also contains the three most important micro-nutrients required by nearly every tree and plant. Iron, Manganese, and Zinc are plant nutrients included in Moon Juice because they are typically deficient in most warm weather soils. In addition, thiamine mononitrate (Vitamin B-1) is also included for its beneficial effects on new plantings. Using Supercharged Moon Juice will enhance your trees' and plants' abilities to ward off diseases, possible infestations, and infections from outside sources. Moon Juice helps plants prevent and recover from the stresses caused by extreme heat, frost, freeze, transplanting, and other events. Use Supercharged Moon Juice to maximize your tree and plant performance! Easy to Use! Supercharged Moon Juice is 1QT of concentrated liquid, so all you have to do is mix with water and apply to the root area. It can also be used for foliar applications as needed.

Question: Can this be fed by watering can instead of foliar feed for potted plants and in the greenhouse
Answer: Yes this can be fed using a watering can. I would recommend you keep the mixture at 1-2oz per gallon.

User questions & answers

Question: I just received this product and there is a date on it 201954531, is this the production date or the expiration date
Answer: No, Bonide Triple Super Phosphate is meant to be used outdoors.
Question: Has anyone tried this on roses? did it work
Answer: Yes, potted roses are typically well established. Follow the label directions for feeding
Question: What are the active ingredients
Answer: Yes, this product is time released.Granular "Bone Meal" and granular "Phosphate" (Or Triple Super Phosphate) are essentially the same thing... with a couple of differences.Bone Meal can take months to "break-down" enough for the plant to be able to absorb the phosphate. This particular product (Triple Super Phosphate), has been "treated" with a form of Acid... (don't freak-out...this acid is similar to "vinegar acid") and this acid enables the "graduals" to "break-down" much faster than Bone Meal.Hence, this product allows the plant "access" to the phosphate much quicker than Bone Meal.I give this product to my plants each spring (read the directions for the correct amount for your specific plant)...and your plants will "reap-the-benefits"...Slowly... but constantly.... over the next few months. However... if your plants are showing signs of phosphate deficiency, I suggest a liquid Phosphate. Liquid Phosphate will "instantly" give your plant phosphate.BUT.... the plant or plants (who are deficient) will "suck-up" the phosphate "very quickly".And, (depending on the plant and it's "phosphate hunger")... after only 1 or 2 weeks (depending on the specific plant, weather conditions and your type of soil)...the liquid phosphate will be "eaten"... leaving your plants hungry for phosphate "again", after a very short period of time.Here is one example: Roses LOVE phosphate. (they also have many other nutritional needs, but lets just stick with Phosphate). If you have Roses... you need this product. Why? Because Roses are "heavy" feeders... and giving them Triple Super Phosphate in early spring... will give them a constant source of phosphate for months.If you ONLY used "liquid" phosphate for your roses, you'd need to feed them phosphate on a weekly basis. This is Good Stuff ! Hope this was helpful.
Question: Does this product contain antifungal capability? Using it for Jade plants
Answer: The beetles we had were black and their larvae was red at the Ash Tree. The adults would invade the house en masse. Very few this year because we sprayed the larvae. Still sprayed the base of the house. My neighbors tried it with soapy water claiming that the beetle's waxy wings would cause the beetle to die. I never put anything chemical on my yard but had to make a change to rid the beetles.
