Pre-emergent herbicide, when applied at the right times of year, will control weed populations before you see them. They do this by inhibiting seeds from forming roots, thus killing them as they germinate.
Eradicating weeds when they germinate is the most efficient way to control weed populations is lawns, flower beds, and even gravel driveways and walkways. It’s time-efficient and cost-effective, saving you months of combating weeds by mowing, weed whacking, hand pulling, digging, and from using costlier products to spray out weeds.
- 25 lb. bag covers up to 4,000 sq. ft.
- 50 lb. bag covers up to 8,000 sq. ft.
- Contains 16-4-8 + Iron plus Barricade pre-emergent herbicide
- This pre-emergent contains a high amount of Nitrogen, so review the "when not to apply" exceptions below for your type of lawn.
Apply only at the recommended rate.
Use our yellow walk-behind spreader to distribute this granular product.
When to apply pre-emergent herbicide:
- Apply 16-4-8 with Barricade to established Tall Fescue lawns in late winter and early spring to feed and prevent weeds. If you've already fertilized your Tall Fescue with nitrogen, then choose 0-0-7 with pre-emergent because it doesn't contain nitrogen.
- Apply 16-4-8 with Barricade to established Bermuda and Zoysia lawns in spring during "green up" to feed and prevent weeds, usually from mid to late April.
- Apply in the morning before temperatures rise above 80 degrees; do not apply during the heat of the day.
- Apply it after one full growing season when your lawn in fully rooted in and you can no longer pull up areas of the sod, after you’ve mowed it at least three times, and after you can no longer see the seams.
When NOT to apply pre-emergent herbicide:
- When seeding new lawns: Do not apply this product or any pre-emergent herbicide if you're planning on reseeding your lawn because it will inhibit germination of that seed too. If you have applied pre-emergent, wait 3-4 months before planting seeds, depending on climate conditions.
-
When laying new sod: Do not apply pre-emergent when laying sod because it will inhibit root formation if applied too soon. Likewise, do not apply pre-emergent before laying new sod - if you have applied pre-emergent, wait 3-4 months (depending on climate conditions) before laying new sod.
- Don't apply 16-4-8 with Barricade to Tall Fescue in late spring or summer; apply it only during cool months; due to high Nitrogen, don't apply to Tall Fescue during warm months.
- Do not apply to Centipede due to the high nitrogen; choose 0-0-7 with pre-emergent instead
- Don't apply 16-4-8 with Barricade to warm-season lawns like Bermuda, Zoysia, and St. Augustine in fall when going dormant or in winter or spring before green up; due to high Nitrogen apply it only when these lawns are actively growing in late spring. Instead, apply 0-0-7 with pre-emergent in fall and winter.
-
Don't apply too soon: If you laid warm season sod in autumn, chances are it will need one full growing season (summer) to root in and fill in the seams, thus skipping the winter and spring applications. If you laid sod in the autumn, here is a general application timetable:
- Zoysia - Safe to apply after Zoysia sod is 12 months old
- St. Augustine - Safe to apply after St. Augustine sod is 12 months old
-
Centipede - Due to high nitrogen, not safe for Centipede at all
- Bermuda - Safe to apply after *Bermuda sod is 6 months old
- Tall Fescue - Safe to apply after Tall Fescue is 4 months old
*TifTuf Bermudagrass is the quickest sod to establish and beats expectations for filling in the seams. If you lay the TifTuf Bermudagrass variety late summer and it’s fully rooted in and no seams are visible, it’s safe to apply the winter application of pre-emergent herbicide.

No taste or texture - it completely dissolves!
Flavor Name: Unflavored, Size: 1.1 Pound (Pack of 1)
Easy way to add fiber to diet. Stir it in coffee or a non-carbonated cold drink. You can't tell it as even added because it completely dissolves.

Keeps me feeling full. Perfect addition to protein shake
Flavor Name: Unflavored, Size: 1.1 Pound (Pack of 1)
Tasteless pretty much. I’ve added to coffee, lemonade, cereal with milk, sauces, stir fry, pasta sauce, yogurt. It’s great addition to my protein drink. It helps me both keeping good on the bathroom but it helps me feel more full and snack less. It has been a secret in helping me lose weight.

A Convenient Fiber Supplement- Digestion, Regularity, Microbiome, Satiety, Hair, Skin, Nails
I’ve tried quite a few fiber supplements over the years, and this one stands out mostly because it combines digestive support with beauty-focused ingredients instead of being just another plain fiber gummy. The formula includes inulin and chicory root fiber, along with a fairly large probiotic blend containing multiple strains like Lactobacillus acidophilus, Lactobacillus plantarum, and Bacillus coagulans. That combination makes sense since prebiotic fiber and probiotics are often paired together to help support digestive balance and regularity.
The added hair, skin, and nail ingredients are also interesting here. Biotin is commonly used for supporting stronger nails and healthier-looking hair, while collagen peptides and keratin are popular ingredients for skin elasticity and hair structure. Vitamin C helps support collagen production naturally, and Vitamin E adds antioxidant support. The apple cider vinegar and saw palmetto are smaller additions, but they round out the formula nicely for overall wellness support.
One thing I appreciated is that these are gummies instead of powders or large capsules. Fiber supplements can sometimes feel like a chore, especially the gritty drink mixes, so having a chewable option made it easier to stay consistent. The blueberry flavor was actually pleasant and not overly artificial. Texture-wise, they were softer than expected and easy to chew.
As far as results, I mainly noticed gradual digestive benefits after about a week or so of consistent use. Things felt more regular and less sluggish overall, especially on days where my diet wasn’t as balanced as it should have been. The fiber content is fairly substantial for gummies, so I’d definitely recommend drinking enough water with them because increasing fiber too quickly can sometimes cause bloating at first. Starting with a smaller serving may help if you’re not used to fiber supplements.
I can’t say I noticed dramatic changes with hair, skin, or nails during the time I used them, but those ingredients usually take longer to show visible effects anyway. Even without obvious cosmetic changes, the combination of biotin, collagen, keratin, and antioxidants gives the formula a more well-rounded feel compared to standard digestive gummies.
Another positive is the allergen-friendly formula. Being gluten-free and free from dairy, wheat, peanuts, and eggs makes it accessible for many people with dietary restrictions. The overall ingredient profile feels thoughtfully put together instead of overloaded with unnecessary fillers.
Overall, I think this works best for someone looking for an easy daily fiber supplement that also offers some additional wellness support beyond digestion alone. The biggest benefit for me was the digestive regularity and convenience factor. The beauty-support ingredients are a nice bonus, even if they may require long-term consistent use before noticeable results appear.
**As always, results can vary from person to person. Consulting a healthcare provider before starting any new supplement is advisable. Keep well (:

Fiber with slight beauty benefits
This supplement definitely falls into the “everything including the kitchen sink” category. You’ve got 10g fiber, 30 billion CFU probiotics, inulin, ACV, plus collagen, biotin, keratin, and vitamins C and E, all in one gummy. In real use, the most noticeable effect is on digestion first, beauty second. The fiber and probiotics actually do seem to help with regularity and a less bloated feeling over time which to me is where this product feels most legitimate. The skin, hair, and nail claims are much harder to directly feel, and honestly those effects (if any) are usually subtle and slow anyway. The main issue is exactly what you’d expect from a formula this stacked. It’s trying to do a lot at once, so nothing is really at a high enough dose to feel targeted. It ends up being more of a general wellness gummy with a strong fiber base, rather than a serious collagen or hair supplement.Taste and convenience are good, and it’s easy to stay consistent with. But like many multi-benefit gummies, there’s a bit of a tradeoff between ease and actual potency. The gummies themselves do taste amazing and I love the texture. They’re also sugar free which is very appreciated. Overall, I’d say this makes the most sense if you want a digestive support gummy with some bonus beauty ingredients layered in, not if you’re looking for strong, noticeable hair or skin changes.

Berry-Flavored Fiber Gummies
These fiber gummies are a quick and convenient way to introduce more fiber into your diet, along with some additional supplements including keratin, vitamins, and probiotics. As these are gummies instead of pills, they're easier to take than trying to swallow whole capsules. The taste is a pleasant berry flavor. While the product packaging prominently displays blueberries, and blueberry flavor is included as one of the ingredients, none of the marketing actually lists these as being blueberry flavored. The price of these gummies ($17.24 with coupon at the time of review) is on par with other fiber supplements, but these have the added benefit of including additional supplements. For awareness, the advertised 10 grams of fiber is only achieved by taking 3 gummies, instead of the lower recommended amount of 2 (which only offers ~7 grams of fiber). After taking these for about a month I did not notice any significant changes or improvements to my digestive health, but effects will vary from person to person. If you're looking for a fiber supplement with some additional vitamins included, these are a good choice.
