Good fertilizer, fast shipping

I ordered the Shropshire Seaweed Organic Liquid Fertilizer. It arrived quickly, took 3 days to reach me in California. Packaging was fine. The product works well on my tomatoes. Price was fair, though shipping felt a little high.

Detailed review of my recent order

I purchased the Shropshire Seaweed Concentrate and a bottle of their Eco-Friendly Oven Cleaner. Ordering online was straightforward, the website was easy to navigate. I received an order confirmation right away. Delivery took about a week, which was okay. The concentrate mixes well and my plants are looking healthier. The oven cleaner works effectively, though it needed a bit more scrubbing than I anticipated for some tough spots. Customer support answered a question I had about dilution ratios promptly via email. Overall, a good experience with quality products.

Reliable source for plant food

I've ordered from Sea-chem a few times now, mainly for their Organic Plant Food and Lawn Conditioner. This recent order was consistent with past experiences. The products always arrive well-packaged and do exactly what they promise. I keep coming back because I know what to expect. This time, shipping was a day slower than my previous order, but still within a reasonable timeframe. Good stuff.

Great value on Muck Munchers

As a first-time buyer, I was looking for the best deal on septic tank treatment. I found the Muck Munchers Septic Tank Treatment multi-pack discount here. It felt like a solid saving compared to other places. Delivery took a few extra days than I expected but for the price, it was worth the wait. My tank seems happy.

Good deal on fertilizer

I got the Shropshire Seaweed Organic Liquid Fertilizer during their spring planting offer. The multi-buy discount made it a solid value compared to other brands I checked. Shipping wasn't super fast, took about 6 days to get to me, but for the price, it felt worth the wait. My plants are looking healthier already.

Got some Fruit Tree Feed

Picked up some Fruit Tree Feed from here. My apple trees look good. It was pretty easy to order, nothing complicated. Delivery was typical, not super fast but not slow either. The price seemed fair enough. I mean, it's just fertilizer, but it does the job.

Love the Compost Accelerator!

I just got their Compost Accelerator and it's fantastic! My compost pile is breaking down so much faster. I am so happy with the results. This makes my gardening life easier. I will definitely be buying this again. You should try it!

Septic tank stuff worked!

So I finally got around to ordering some Muck Munchers Septic Tank Treatment. Heard good things, and honestly, it seems to be doing the trick. My tank was getting a bit smelly, but it's much better now. Delivery was alright, it arrived in about 5 days. Just wish they had smaller packs to try first, but the multi-pack was a decent buy.

Anyone know how long delivery usually takes for Sea-Chem stuff to somewhere like, say, California? Trying to plan out my garden treatments.

J Jason Turner 1 month ago
Oh, shoot, I don't think they ship outside the UK. I remember looking into it once for a friend in Canada and it wasn't an option. Might want to double check though.

J Jacob 4 weeks ago
Nah, pretty sure they're UK only for shipping. You might need to find a local distributor or a similar brand if you're in the US.

Do they ever do a first order discount? Thinking of trying out their seaweed fertilizer.

S Sofia Green 1 month ago
Not really, I haven't seen one. They tend to do more volume discounts or seasonal sales.

Nah, I signed up for the newsletter and never got a first-time code. Keep an eye out for their Black Friday stuff though, that's usually decent.

Is the Shropshire Seaweed liquid fertilizer actually organic certified? Or is it just 'natural' sounding?

K Katie Lewis 1 month ago
Yep, it's certified organic. They mention it on their product pages, I specifically looked for that when I bought mine.

S Sean Scott 1 month ago
They are definitely organic certified. That's one of the main reasons I started using their products over others.

Hey, thinking about grabbing some Muck Munchers for my septic tank. Does anyone know if they do any multi-pack deals or discounts for buying a bunch at once?

D Donna T. 1 month ago
Yeah, they totally do! I bought a bigger pack last month and saved a decent amount. Check the product page, they usually list the bundle discounts there.

Can confirm, pretty sure I saw multi-pack savings for Muck Munchers when I was checking out their site a while back. It's their thing, volume discounts.

Got a discount code from their newsletter, but I can't figure out where to put it on the website. Help?

M Mary W. 1 month ago
You enter it at checkout, right before you finalize your payment. There should be a box for 'discount code' or something similar.

S Sean Smith 1 month ago
It's usually on the last page of the checkout process, look for a small link or a box for promo codes.

Oh, I don't think they ship outside the UK mate. Last time I looked it was only within the British Isles.

Pretty sure they're a UK-only operation. You might have to find a local alternative or a reseller if you're in the US.

Hey, wondering if the Shropshire Seaweed stuff is actually organic? Like, truly certified or just 'eco-friendly' organic?

H Hannah Johnson 4 weeks ago
Yeah it is. I checked their site when I bought some for my tomatoes, they're certified. It's proper organic.

Is the Muck Munchers stuff actually safe for pets? Got a curious dog who likes to 'sample' things around the house.

E Ella Phillips 1 month ago
Yeah, their cleaning products are pet-safe. I use the oven cleaner and my cat's fine, no issues.

M Mary Wilson 1 month ago
They specifically mention pet-safe on some of their products. Always good to double check the specific one you're buying, but generally yes.
