3-Minute Installation
The Ultimate Indoor Watering Solution
Easy To Install
Remove a handful of dirt and push the the Oya™ Watering Spike straight down or at a slight angle (whatever fits best) into the pot until 2/3 of the spike is buried.
Fill the Oya™ Watering Spike, surface water, and you're done!
When To Refill
First, follow any watering instructions on the original plant tag. Then, put your fingers two inches into the soil and:
- If your plant doesn’t like a lot of water and the soil is cool, WAIT until the soil is dry to refill your Spike once it’s empty.
- If your plant likes water and the soil is cool, refill your Spike when it’s empty.
Continue to surface water when you refill the Spike.
The Patina
The top of the Spike will develop a Mineral Patina pattern. Similar to how leather changes color, the mineralization of water will create unique white rings around the exposed area of the Spike. This is 100% natural, promotes healthy mineral separation, and creates a unique look on each spike.

These ollas hold enough water for a single plant in a pot to last a couple of days. Nice that you don't have to perch a plastic bottle on top. Perhaps you could, I haven't tried it. At any rate they are very functional and cute!
Peace of mind. We were away for 7 days. I filled all spikes full before departing. When I arrived home yesterday the spikes were empty (which I expected) but the soil was moist AND all plants were doing great! Just what I had hoped for!
The plant are still alive after two weeks, a record for me balcony. Saying up to five days is a stretch, I berley get three.
Easy, Efficient, Effective! I’ve been looking at getting these for a while now and finally did. I set it up before going on vacation in my grow bags and in a corner of my raised bed that doesn’t have a drip connection. It kept my potatoes and ginger going strong while I wasn’t home and they’re super easy to fill back up etc. love mine!
Love these teardrop shaped growoya. Perfect for my potted plants.
I love the Ollas! The small ones are wonderful for pots. The medium ones and larger ones are great for raised beds. I've attached 2 photos, one shows the small olla in a container pot with yellow bee balm and the other shows the larger size in one of my raised beds. It's mid-spring here in Tucson, so I've already covered my raised bed with shade cloth. One can just see the beginning of summer seeds popping up and 2 Wooley Milkweed plants under the black shade cloth. The yellow bee balm is doing quite well in the container. The milkweed and summer seeds were just recently planted so they are still small.
LOVE THEM! They will be used in my grow bags. I am very familiar with this product and have approx 10+ Oya’s in-house that I have been using for the past several years for my raised above ground planters. Also, the large size Oya keeps my two rose shrubs very happy. No over watering! PS: my son who lives in Washington State, just purchased 4 large Oya’s for his raised garden bed - he keeps hearing me talk about how great they are.
These are absolutely fabulous for pots!
Great product, easy to use, fast shipping!
I live in an apartment without any exterior water. Using a water can from my kitchen I can bring water to my planters on my small patio and it keeps staining water from going on to the patio . Perfect ! thank you
I’m in the process of planting spring seeds. These spikes are a gift of water in the AZ desert.
Growoya helps hanging baskets thrive.
Love it! I consistently kill plants - mostly through worrying over them and over-watering. With the oya spikes it's just like filling my own glass of water - I check how if my plant's "cup" is empty and refill as needed. My orange trees have happily thrived!
Nice color. Blends in with the garden.
Great to use
I'm experimenting with grow bags and containers this season, but seem to struggle with the watering needs. I've added GrowOya to the containers of the unhappy plants. I'm happy let my plants recover from my mistakes with a watering system that is designed to give them what they need.
This is a birthday girft for my daughter. I am looking to purchase a couple for my self as well soon when these are on sale.
I love the Growoya ollas and have had good success with the pots and the spikes. In general they work better than my homemade ones and some cheaper ones I’ve found on Amazon. My only complaint is the confusion on the website regarding shipping. Some of the items say free shipping over $50 but when you put >$50 in your basket it tells you that you need $x more to be greater than $125 to get free shipping. Basically what I see and understand is that you have to order more than $125 for free shipping. The seller should probably revise the website to reflect the correct info. Other than that I will continue to buy these ollas.
I have been a Grow Oya fan for years, using them in my outdoor planters to grow flowers, herbs and even trees! But my indoor houseplants have been suffering. I have actually had the thought multiple times that I wish there was an Oya I could use inside my house. And now there is!! The Oya spike is the perfect solution to keeping my indoor plants healthy and thriving. I love that I only need to fill it up once a week or so and it looks so pretty too. In my plant pot, it sticks up just a little bit and looks really beautiful nestled amongst the green leaves. Thank you GrowOya for continually bring us new and amazing products!
Love these & so do the plants.
Finally some help for my beds during the blazing heat and strong winds out this way! Thank you Growoya :)
Love them so far. I am using them in crates that I am trying to grow potatoes in. We are going away for a week. I have no doubt that my potato plants will have plenty of water while we are gone.
These are great. I had some outdoor potted plants in the bright sun that were drying out too fast. If I forgot them for a day, they were in trouble. The growoyas are definitely making the situation more forgiving!
I have a couple finicky indoor plants that I forget to regularly water. These help keep the soil moist. They’re also the perfect size for small outdoor pots. I plan to buy more next garden season for my herbs etc. that I put in small pots.
Great for small gardens or pots!
Great addition to our potted blueberries and grow bags!
Small but keeps plants watered
Love these- they’ve already gotten my herb pots through a heat wave, leaving everything (including starts) healthy and thriving. I will be getting more, and gifting them to friends.
I am loving the new smaller size, using in outdoor smaller pots, strawberries are loving them. Have never had a breakage during shipping for any of the sizes I have purchased.
My indoor plants are often forgotten. The new Spikes have added some reassurance that they will survive! Plus, they look good in the planters!!
This is an excellent product for house plants in large pots. Quality is exceptional. I purchased 4 of these spikes recently. Love them! I've also purchased several of the medium and large Ollas for my outside gardens. This is a wonderful product! Jane B.
We live in the mountains in Arizona. The Oya has come in particularly handy as a watering method. It keeps our plants hydrated so we don't have to worry.
Much better than the spike which requires a glass bottle.

We don't recommend putting fertilizer IN the Oya as most fertilizers are not 100% soluble, so this could clog the porosity of the Oya. Instead, add fertilizer when you surface water.
Is dark growth on the exterior normal?
Some dark, natural growth can occur naturally on the exposed area of the Spike. If this is bothersome, it can be easily wiped off with a damp cloth.
