Consistently good plants

I've ordered from The Sill a few times now, and they're always reliable. This last order was a Monstera Deliciosa, and it arrived in great shape, just like my previous Pothos. Packaging was secure, and it got here in about 4 days. It's why I keep coming back.

Healthy plant, decent delivery time

I recently bought a ZZ Plant and a self-watering pot from The Sill. The ordering process was straightforward on their website. The plant arrived well-packaged in about 5 days, which was reasonable. The ZZ Plant looked very healthy upon arrival, no bent leaves or anything. The self-watering pot works as described, making it easy for me, as I tend to forget to water sometimes. I had a quick question about care, and their online chat support was helpful. Overall, a positive experience and the plant is thriving.

Love my new Fiddle Leaf Fig!

Oh my goodness, I just received my Fiddle Leaf Fig from The Sill and it is absolutely gorgeous! It was so carefully packaged, not a single leaf was damaged during shipping. It looks even better than the pictures online, and it's already making my living room feel so much brighter. I am so happy with this purchase, I will definitely be ordering more plants from them again soon!

Are their plants good quality? Like, compared to Bloomscape or something. Don't want to pay a lot for a dying plant.

A Anna Doyle 1 month ago
I've gotten a few from The Sill and they've always arrived in good shape. My monstera is thriving! I'd say they're comparable to Bloomscape, maybe a bit more selection for smaller plants.

My ZZ plant from The Sill is still going strong after a year. Heard some mixed things about Bloomscape lately, so I stick with The Sill mostly. Plus, they have that 30-day guarantee if anything goes wrong.

Can I use my 15% off new customer discount with a free shipping code if my order is over $99?

C Colin V. 1 month ago
Nah, I tried that before. They only let you use one code at a time.

R Raj 1 month ago
Yeah, I wish! You usually have to pick between the discount code and the free shipping if you have a separate code for it. The free shipping over 99 applies automatically though, so you can still get your 15% off *and* free shipping if your order hits the minimum *after* the discount.

Has anyone used The Sill's plant subscription? Is it worth it or should I just buy plants individually?

R Rosa 1 month ago
I did it for like 3 months. It's kinda cool if you want a surprise and don't care too much about picking, but I ended up with a couple plants I already had so I cancelled. Good for beginners though.

Hey, I'm thinking about getting a plant from The Sill, but I live in Boston. How long does shipping usually take to get there?

A Andre C. 1 month ago
I'm in Philly and it usually takes about 5-7 business days for me. I think they ship from a few different places so it might vary a bit for Boston.

Mine arrived in like 4 days to NYC, totally fine. They ship pretty fast.
