Best Hose-End Sprayer For Organic Gardeners

Hudson Hose End Sprayer Professional

$16.00

A decent hose-end sprayer is perfect for applying liquid organic fertilizers and inoculants.

I’ve had a few professional hose-end sprayers over the years, but for some reason, they keep being discontinued.

I used to use a Gilmour sprayer, then a metal trigger Hudson hose-end sprayer, which, as far as I could tell was exactly the same as the Gilmour – perhaps even made by the same manufacturer.

But that’s been discontinued, too.

So I’ve been using this lower-end Hudson Chameleon hose-end sprayer and it’s been working well for me, although the online reviews I’ve read are definitely mixed, which makes sense – it’s made of plastic and can definitely break if it gets banged up.

But that’s what I’ve been using these days, and so far, so good. I buy them for $13 wholesale and sell them here for $16, so I won’t be retiring anytime soon 🙂

When spraying, my goal is to spray both the top and bottom of the leaves of my plants with a spray that isn’t too coarse and isn’t too fine.

Too fine and I know I’d be harming some beneficial microbes in the spray. Too coarse and the spray doesn’t stick as well to the leaves. This sprayer creates the right water drop size.

If you’re combining products that all have different dilution rates, just use the highest dilution rate.

For example, if you’re combining EM (1:250 dilution) with seaweed (1:50) and molasses, make sure you get your 1:250 ratio for your EM (which is to set the sprayer dial to 1 Tbsp) and the others will be fine even if they’re more diluted, i.e. it’s always okay to dilute more with water, just not less.

So if I was going to spray a 1000 square foot garden, I’d add 1/2 cup of seaweed, 1/2 cup of sugar or molasses and 1/2 cup EM, then set the dial to 1 (a 1:250 dilution) and spray the whole thing.

Actually, I’d dissolve the sugar or molasses in 1/2 cup of warm water first and add that to the bottle. That changes my dilution rate, which means I can set my dial to 2, which means the sprayer will have better luck pulling up the solution.

I often fill the remainder of the container up with water, especially if I’m spraying a solution with molasses or fish, as they’re a bit thicker and the sprayers can sometimes have a bit of difficulty sucking them up, especially if water pressure is low.

The last part is cleaning. With any sprayer, always clean it right after use. It just takes a minute.

I rinse out the container, fill it with water and then spray some of that water to get all of the gunk out of the internal parts. Do that and these things will last a lot longer!

In summary, this Hudson sprayer is a high-quality sprayer, with the only downside being that the dial is a bit hard to turn, but I believe it’s the best hose-end sprayer for organic gardeners – let’s start spraying!

  1. Okay, I have liquified seaweed and also BioAg probiotic additive that I want to spray in my planting beds. Recommended application rate for the seaweed is 2 Tbs per gallon. Recommended application rate for the BioAg is 1 Tbs per gallon. My plan is to put those amounts into my Gilmour 362, set it to 1 Tbs per gallon and spray until the mixture is all gone. Is that a good plan?

    1. Almost. But what I would do is try to figure out the square footage of the area you’re spraying first. Then, per 1000 square feet of area, add 1/2 cup of BioAg to the container and whatever amount of seaweed is appropriate, then set it to 1 Tbsp per gallon and spray that over the entire area – that way you’re getting proper quantity and proper dilution. I know there’s a bit of math involved to figure out square footage, but once you’ve done that, you’ve got it. It gets a little more tricky if the product label doesn’t tell you how much to apply per area (for example, 2 Tbsp per gallon is helpful for dilution, but I also like to know how much per 1000 square feet), but for your seaweed, odds are that 1/2 cup is also appropriate. If you need help figuring out square footage, send me some photos and I’ll do my best to help.

      1. I would LOVE your help! Problem is we don’t have a single planting bed that is square or rectangular. There are curves, half circles, circles, comma-shaped beds with rocks and gravel in between (with weed-block under the gravel) and a concrete sidewalk running through the middle. That’s just the front yard. The back yard is even more fun with decayed granite paths (with weed-block under) and grassy areas, some trees and scattered planting beds. The weed-block does let moisture through, so should I be spraying the gravel as well then? If so, figuring the square feet will be a LOT easier! Just measure the width and length and multiply. Not counting the pathways, I doubt that we have 1,000 square feet to spray, but I could be wrong.

        1. A fast way to estimate is to figure out the full square footage and then estimate what percentage of that is taken up by paths and then subtract. If the full yard is 40 feet * 40 feet, that’s 1600 square feet. If the sidewalks take up about 1/3 of that space, the garden area is about 1000 square feet.You certainly can spray the gravel.

          1. How much molasses would you add to this mixture? You think this formula should be applied once a month during the growing season?

          2. Apply the same amount of molasses as EM. Yes, I apply monthly.

  2. I have a Chapin 6004 wet hose end sprayer and use the Neptune’s Harvest seaweed fertilizer with it. I constantly have clogging issues. Will the Gilmour hose end sprayer 362 alleviate this problem or is there something else I should do? Thanks for your help!

    1. I’ve owned that Chapin as well. One trick is to mix your seaweed with equal parts water to help it get through better. This spring I plan to do some more side by side testing with Neptune’s stuff to see which of my sprayers does the best with it, but I didn’t have problems with the 362 last year, so I recommend you try it, and if it doesn’t work, let me know and I’ll be happy to refund you.

      1. Thanks, Phil. I’ll give it a whirl. So did you mix your seaweed with equal parts water when you used it in the 362? And do you need to account for this dilution when calculating the proper amount to use?

        1. Sorry for the late reply – I’ve been away. I mix my seaweed with other products that tend to have the consistency of water, such as EM, so probably that helped. As for accounting for the dilution, yes in theory you would do so. I actually don’t mind a more diluted application rate, so I don’t worry about that much, but since mixing with equal parts water would effectively double the dilution rate, you could double the rate on the dial (e.g. go from 5 Tbsp per gallon to 10).

  3. Phil, can you recommend a water filters to remove impurities, or should I be concerned about this?

    1. It’s worthwhile getting a filter for your hose. I can’t recommend a specific one at this point, but I’ll be looking more into that soon.

    2. Anita Malherbe says:

      Hi There
      I am from RSA and cannot order from you. I can get EM, Kelp and soja( instead of fish emulsion) I also have good compost and blackstrap molasses. What is a good source of pottasium in organic gardening to stimulate flowering and fruiting? I really like to follow your ideas. Thank you.

      1. Potassium doesn’t particularly stimulate flowering and fruiting. It is an important nutrient and does a lot of things in the plant, some of which may be related to fruiting, but it does a lot more than that. That said, I wouldn’t go applying much potassium unless I had a documented deficiency. In that case, potassium sulfate is an excellent source if you need K and S, Sul-Po-Mag is great if you need K and S and Mg.

        1. Anita Malherbe says:

          Thank you so much. I started today to feed my grass with kelp, fulvicacid,EM and Trelmix. Trelix is a micro element mixture. Hope my grass will react in a positive way.

  4. Plan to spray my lawn with Talstar insecticide and the manufacturer recommends 1 oz per 1000 sq ft. I have 2000 sq ft to cover. If I put 2 oz of Talstar in the container… what should the dial be set at?

  5. Should I worry about using city water from the garden hose. Won’t the Chlorine and other chemicals in the water harm the bacteria, mulch, and fungi in the soil?

    1. It’s not ideal, but not the end of the world. Some chlorine will dissipate in the air, some will be broken down my microbes, some is actually used by plants as a nutrient, and some may harm some microbes. You can buy a chlorine filter for the hose, but you need to make sure it won’t decrease the water flow rate too much.

  6. Pat Bartels says:

    Within your link to Best Hose End Sprayer you have a link to sprayer instructions. When I click on the link I get a 404 error.

    1. Thanks for letting me know, Pat. I can’t find the new instruction page. I’ve emailed the manufacturer, but no response so far.

  7. Does this spayer work well with small quantities? I have a 200 square foot garden, so I am often using just a few tablespoons. My Ortho sprayer does not consistently draw from these small amounts. Would the Hudson sprayer work better?

    1. I don’t think the Hudson will be much different. With any sprayer, when I’m using small quantities, I just put some water in there to compensate.

  8. Karen Derrer says:

    I purchased the hudson self mixing garden sprayer but it doesn’t seem to mix the ingredients. I put all the ingredients into the spray bottle (150 ml) total. I attached sprayer to hose & began to spray my plants. I did not visually see the ingredients being mixed nor, after 30 min of spraying did the 150 ml reduce in amount. I have a lot of water pressure. I’ve checked the sprayer for any debris or washer failure, but seems fine. Any suggestions?

    1. I don’t think “self mixing” means that it mixes the ingredients but rather that it mixes the ingredients with water from the hose so you don’t need a standalone sprayer. In terms of mixing the ingredients, I always just shake really well. If the sprayer is having trouble sucking up the ingredients, it may be because you have something thick in there such as molasses, which benefits from being dissolved in warm water first. Regardless, sometimes you just need to decrease the dilution a little bit, such as by turning the dial from 1 to 3, 4, or 5 (whatever you need to get it to come through). Sometimes I turn the dial to 10 just to get it started and then I can decrease it back down to 1 or 2 or 3 once it’s sucking up nicely.

    I just discovered you, and now it’s September 20–too late for the growing season! However, after 2 years I am still struggling to get my new Ecolawn established here in southeastern CT and am about to overseed for the second (annual) time. After 2 years of an intense crabgrass attack (no, I didn’t apply pre-emergent, but believe me, I will forevermore), I’m beginning to wonder if Ecolawn just can’t thrive here. My question is: is it too late in the season to help the Ecolawn overseeding, or also my 2 large perennial beds? I can’t wait for next year to get started with your approach. Thank you!

    1. If you’re asking about it being too late for overseeding, you’re definitely late, but some seed may take if the weather stays warm this fall. If you’re asking about spraying organic fertilizers and microbial inoculants, it’s still useful. I spray in October and even November.

  10. Deborah Steele says:

    Thanks! I’ll get started, then!

  11. I just got this sprayer and there is a lead warning on it. What is the source of the lead, and will it transfer to the plants?

    Thanks!

    1. Hi Nisha, the lead is in the handle, and no, it won’t transfer to the plants. The state of California is especially strict when it comes to labeling, which is why the warning is there.

  12. I have a powdered kelp. The instructions read 1/4 tsp per 3 litres of water. How would I mix this in with my EM in my Hudson house end sprayer?

    1. Hi Traci, I can help. Just have a couple of questions: How big is the area? How often are you planning to spray?

  13. kathleen m peterson says:

    I do all my planting in containers. Are the amounts the same?

    Thank you.

  14. Hi Phil, My first go on the sprayer and it doesn’t appear to be working. I wonder if the molasses is a problem. I’ve already filled the sprayer with BioAg (EM), fish fertilizer, seaweed fertilizer, and molasses (to cover a large area). I’m hoping I don’t have to waste this product. I did miss the instruction about warming the molasses first. I’m using it on the setting it came with for 1 T.
    Thanks again for your help!

    1. Yes, the molasses can be a problem. Shaking it really well can help dissolve it somewhat. Then, you can increase the setting to 5, and if necessary, as high as 10. What I do if I’m ever spraying something thick is I do a first pass at setting 1 to make sure the leaves are wet and then I come through at setting 5, 7, or 10, knowing that I won’t burn the leaves because I’ve already wet them.

  15. Super helpful, Phil! I really appreciate all your help getting me started.

  16. Great website and advice, Phil! I have a question about sprayers. I am an apartment dweller and don’t have a hose to attach to the kind of sprayer you suggest. Also, I only have a small patio of plants. What do I look for in hand sprayers to make sure the good stuff comes out right?

    1. Just use a spray bottle. There are probably higher-quality ones that may be worth a few more dollars, but I think all of them are simple enough in terms of design that the good stuff gets through them.

  17. Are you supposed to be able to turn the water off with the handle of the spray? Once I turn on the hose water, it starts spraying and won’t release. I don’t have to squeeze the handle to get water — it just goes and goes. I’d like to be able to walk across the yard without the spray going. How do you shut it off?

    1. There’s a little metal thing that can be set to keep the sprayer spraying. This is there to save your wrist, like you find at some gas stations on the gas pump. Perhaps that thing is holding the handle in the on position?

  18. I can’t seem to unclog my sprayer. I just used it for applying beneficial nematodes, (they come mixed in DE), I filled the bottle of the sprayer with water to mix it well , the I had the dial set on 1 and for the first minute I could see the amount going down in the bottle. But after that, no matter how much I turned the dial (I tried all settings) the bottle would not empty. I finally put the mix in a pump sprayer so that it wasn’t a total loss. Then I hooked the sprayer up to my hose to clean it and it still won’t empty the bottle. Is there some other way to clean this?

    1. When my sprayer has clogged, I’ve filled it up with hot water as well as submerging it in hot water for a while, hoping to melt what may be stuck in there. I’m not sure whether that will unclog the DE, but it has always worked for me with other fertilizers. Worth a try. You’ll probably find other ideas with an online search. Please let me know how it goes – I’d love to learn of any other methods!

      1. I wish I would have read through all these comments before applying my fertilizer spray. My molasses was clogging my sprayer. The way I got around it was to unscrew the bottle, and the clogging appeared to be at the screen where the fertilizer uptake occurred. I would rotate the tube so that when I had water coming out the nozzle it blasted into my screen. That would remove the black clog. I was always afraid that my screen would go flying somewhere, but that didn’t happen – at least not yet. Hopefully when I dilute better with warm water, I will not need to do this anymore. Out of curiosity, do you sell replacement tiny screens? Also, are additional plastic bottles available?

        1. Sorry, the manufacturer doesn’t sell replacement screens or bottles for this sprayer, not that I’ve seen.

  19. Does BioAg go bad? I bought a jug of it from you at the beginning of last year and still have some left.

    1. It can go bad eventually, but I very often use it for 2 years after the best before date and it still works very well.
