    Best landscaping pros on the planet
    Sandy G.

    J Harold Mitchell Landscape Supply is easily the best store in LA county for irrigation parts. It's a wholesaler that also sells to the public, which means better products that are intended to hold up in commercial use. Not Big Box store thin plastic crap, but quality parts that last. Three locations: Cypress, San Gabriel and my favorite, Altadena. They stock the best brands in the landscape trade...Rainbird, Hunter, Toro, Netafim, etc. The store has everything possible for irrigation installation & repair, plus kickass hand tools for serious garden work, a good variety of beautiful, quality landscape lighting, plus benderboard, fertilizers, potting soil, bagged mulch and fountain pumps and more. The retail prices are good, cheaper than local hardware stores. Plus the parts will last so you won't be replacing them soon and using up all your time, money & resources. The store is in a smallish, white industrial building, kind of hidden, on Woodbury & Windsor in Altadena. It's clean, organized, well-lit and doesn't smell all rubbery or dieselly like other landscape stores. If you have a vague grasp of how to approach your irrigation issues this is a fantastic resource. Check in at the front counter for quick assistance or wander if you want to see the latest drip irrigation parts. Some stuff is behind the counter, so not completely self-serve, which is a really great old-school touch. The guys will help you troubleshoot & will help you find the parts you need. They offer occassional bi-lingual free instruction classes in irrigation controller clocks, lighting installation and it's not just product reps selling their brand but actual trouble shooting & instruction. This is a real service which homeowners & DIYers should get on! If you want to geek out with manufacturers catalogues, ask for a complimentary copy. Kinda like reading the tool section of the ginormous old Sears catalogue (yeah, that was a thing kids did in the 60s). The manufacturers provide these catalogues to wholesalers and they are great to share with clients or use as your own textbook. So ask for some! I love this store. The guys who work here are so smart & well-trained. They know their stuff & can help you save water & save time. Thanks for being here, J Harold Mitchell Landscape Supply!

    I needed to add lighting in my dining room. I have been in this house for three years, the ceiling…read morein the dining room didn't have a light fixture. We had two lamps, but I didn't like it because you have to walk over to the lamps in the corner to turn them on in the darkness! An electrician installed a ceiling connection and wired it to a wall switch by the room entrance. I browsed the Lamps Plus website and went to the Pasadena location to see their products in person. So glad I did, I got a good look and selected the perfect ceiling fixture for my home. The sales personnel were very helpful and made recommendations, which made it easier to narrow my choices down to the final three. They have "fancy" chandeliers, LED lighting, wall scones, floor lamps, interior and exterior lighting options. I learned so much about the different styles such as a flush mount, a hanging swag light, and features such as a dimmer with different light tones from high to low. I chose a Mission Tiffany Pendant light (sounds like a necklace, lol). As I write this review, I am in the dining room with the light above me! All I have to do is flip the switch and the room glows. It's the perfect addition to my home. I recommend browsing on their website or coming in person to see first-hand what your options are. Sincerely, Rosemary

    Great customer service! The whole team was super friendly and Carlo helped me process my order…read more Gave me a lot of good tips about the light direction and bulbs, which saved a lot of time. Would gladly come back here again.
