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.

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.

Mystical, layered, and thought-provoking
Format: Paperback
This book took me on a serious deep dive. I’ve read Jasher before, but this version gave it new life with clean translation and smart notes. Ina Quant and the Three Jubilees were new to me—and honestly, they pulled me in with their strange, prophetic rhythm. It’s not a casual read, but if you’re spiritually curious or love ancient texts that go beyond the traditional canon, this is a goldmine. It felt like uncovering the other half of a story I didn’t know was incomplete.

21 Microneedling Pen Cartridges for Dr Pen. Well Made; Sanitary; Perform Well; Good Value
Aiscool 21 Pcs Microneedling Pen Cartridges for Dr Pen A6/N2/M5/M7 Replacement Tips 0.25mm by Aiscool I sampled this 21-piece cartridge set to use with my compatible Dr. Pen device, and I was impressed by the variety included for the price. Having a mix of 36-pin, 12-pin, and round nano cartridges makes this kit much more versatile than single-style refill packs. I liked being able to switch between gentler skincare applications and more focused microneedling sessions without needing separate orders for different cartridge types. The cartridges were individually sealed, which added reassurance about cleanliness and storage. The fit with my compatible device was secure and consistent. Each cartridge locked firmly into place without wobbling or shifting during use, which is something I pay close attention to with replacement tips. The needles moved smoothly across my skin without snagging or dragging, and I did not notice bending or dullness during normal use. The 0.25mm depth is also a comfortable option for lighter at-home treatments with minimal downtime afterward. I also appreciated how convenient this set is for maintaining a regular skincare routine. The nano cartridges worked well for serum application and gentler sessions, while the higher pin counts covered larger areas efficiently. The cartridges themselves are lightweight, and while the plastic housing does not feel especially premium, the actual performance was dependable. I made sure to inspect each sealed cartridge carefully before use, which I would recommend with any microneedling accessory product. For the price, this set delivers strong value if you already own a compatible Dr. Pen model and go through cartridges regularly. The combination of variety, compatibility, and individually sealed packaging makes it a practical refill kit for routine personal skincare use at home. Pros: ✅ Includes 36-pin, 12-pin, and nano cartridge options ✅ Compatible fit with supported Dr. Pen models ✅ Individually sealed for cleanliness and convenience ✅ Needles glide smoothly without dragging ✅ 0.25mm depth works well for lighter at-home treatments ✅ Good value for a 21-piece mixed set Cons: ❌ Plastic housing feels somewhat lightweight ❌ No protective caps over the needle openings ❌ Compatibility limited to certain Dr. Pen models ❌ Requires careful sanitation and inspection before use

Fit my Dr. Pen perfectly!
I picked up this 21-piece microneedling cartridge set for my Dr. Pen device, and overall it’s a very solid value for at-home use. For the price (around the low $30 range), you’re getting a useful mix of 7 nano, 7 12-pin, and 7 36-pin cartridges, which makes it easy to switch between lighter skincare treatments, product infusion, and more intensive microneedling sessions without buying separate packs. Compatibility was exactly as expected. The cartridges fit my Dr. Pen M7 securely with no looseness or alignment issues. They clicked into place properly and stayed stable during use, with no wobbling or skipping, which is important for a consistent treatment experience. In actual use, the performance was reliable. The needles worked smoothly on the skin, and I didn’t notice any bending or breakage. Each cartridge comes individually packaged, which helps maintain sterility and makes them convenient for single-use sessions. The different tip types also give good flexibility depending on whether you want gentler nano-needling or deeper penetration with the 36-pin option. That said, the build quality is a bit on the simpler side. The cartridges have a slightly plasticky feel and a blue-purple tint, so they don’t look as refined as some higher-end alternatives I’ve used. However, since these are disposable, that cosmetic difference doesn’t really affect performance. Pros Great value for a 21-piece mixed cartridge set Includes nano, 12-pin, and 36-pin options for different treatments Secure fit with Dr. Pen devices, no wobbling during use Individually packaged and sterile for hygiene and convenience Needles perform smoothly without bending or breaking Cons Build quality feels a bit lightweight and less premium Plastic housing looks and feels cheaper than higher-end brands Single-use design means ongoing repurchase required Not much differentiation in “feel” compared to more expensive cartridges during use Overall This is a practical and cost-effective cartridge set for anyone doing regular at-home microneedling. While it doesn’t have the premium finish of higher-end options, it delivers where it matters—fit, sterility, and consistent performance. For the price, it’s a very reasonable and useful refill pack for routine skincare use.

Good Variety Pack With Solid Compatibility, But No Protective Caps
This is a review for this 21-piece variety pack of Dr. Pen microneedling cartridges. For around $32, this actually feels like a pretty solid value overall. You’re getting seven nano cartridges, seven 12-pin, and seven 36-pin, so it’s a nice mix depending on whether you’re doing product infusion, lighter treatments, or more intensive microneedling sessions. I always appreciate a variety pack because otherwise you end up buying giant boxes of one type and suddenly becoming emotionally committed to 36-pin needles for the next six years. These fit my Dr. Pen M7/M7S perfectly with no issues clicking into place or staying secure during use. I didn’t have any wobbling, uneven dragging, or weird skipping while microneedling. Functionally, they performed just as well as other replacement cartridges I’ve used. That said, they do look and feel a little cheaper than some other cartridges I’ve purchased before. Not necessarily unusable, just not quite as sturdy or polished-looking. Since these are single-use anyway, that may not matter to everyone, but it was noticeable. My biggest hesitation is that these do not come with protective caps over the needles. To be fair, the listing photos actually do show them packaged this way, so it’s not misleading — they were honest about it — but personally I’m just more comfortable when cartridges have caps for an added sense of sterility and protection. They are individually vacuum sealed with expiration dates, which I do appreciate, but I’ll probably use my capped cartridges first before reaching for these. Because of that, I’d feel a little more comfortable initially using these on areas like the chest or neck rather than jumping straight into facial treatments, at least until I’ve tested them more thoroughly. I’d also definitely be extra cautious about sanitizing everything beforehand. Overall though, for the quantity and variety included, this still feels like a decent buy if you go through cartridges regularly.
