Best Hanging Planters Outdoor: Seven Models, Their Chains and Their Reservoir Claims

As an Amazon Associate we earn from qualifying purchases. Details

The best hanging planters outdoor are the ones whose chains, drainage and watering setup suit how and where you will hang them. This guide compares the seven hanging planter models in our research set. Each model has chains or a chain rack in its listing, and most describe UV or weather resistance. Only two mention frost resistance, and none gives a hook load limit or a measured watering interval. This article compares what each listing says and marks where the listing stops.

Quick answer

• All seven models come with chains or a chain rack, so each is a hanging planter and not a pot for a stand. Two list frost resistance, from zople and CNLBO.
• Iowa State University Extension says hanging baskets may need water once a day on hot, sunny days. The reservoir claims run from 7 to 14 days on one fill, so treat the reservoir as a backup and check the soil by hand.
• The reservoir sizes differ. The UOUZ listing gives 50 oz and the CNLBO listing gives 43 oz, which is 50 minus 43 = 7 more on the UOUZ.
• Check the chain and hook before anything else, because none of the listings gives a load rating.

What the hanging hardware is asked to carry

A hanging planter carries the weight of the pot, the wet soil, the plant and any water in a reservoir. The listings describe chains with S-hooks or chain racks, and only the zople and UOUZ bullets state a chain length. The rest describe chains or racks without a length.

• zople: an iron chain with an S-hook, adjustable up to 24 inches.
• UOUZ: two 23.5 inch electroplated chains with S-hooks, described as rust-resistant.
• CNLBO: rust-resistant metal chains, with the cotton wick in the pot.
• WSMKSZ: triple chains that the bullets call heavy-duty and adjustable in height.
• SQKH 13 inch, SQKH 12 inch and WUCEIAUU: chain racks, two in each set.

The Penn State and Iowa State pages we opened do not address hook strength or chain load, so the hardware checks in this article rely only on the listings. Weight also depends on the soil. A large pot of wet mix is heavy, and no listing states the weight of a filled planter.

Outdoor wording and reservoir claims, model by model

Table 1 sets out what each model’s listing says about size, reservoir and outdoor use. Where a listing has color variants, we show the variant in the card and name the others here.

Table 1: what each listing says about size, reservoir and outdoor use

No.	Listing	Size as listed	Reservoir or watering claim	Outdoor wording
1	zople 12 in, 2 pack	12 inch	Reservoir said to keep plants hydrated for up to 2 weeks	UV- and frost-resistant plastic
2	CNLBO 12 in, 2 pack	12 inch, 43 oz reservoir	Cotton rope wick; 7 to 14 days on one fill	UV-resistant polypropylene; frost-resistant material
3	SQKH 13 in, 2 pack	13 inch	Water reservoir with a removable saucer; no interval stated	Withstands harsh weather without fading or cracking outdoors
4	UOUZ 13 in, 2 pack, black	13 inch, 50 oz reservoir	Removable reservoir; 7 to 14 days watering-free	UV-resistant, weatherproof plastic
5	WUCEIAUU 13 in, set of 2	13 inch	Recessed base acts as a reservoir; “for weeks”	UV-resistant, weatherproof plastic; sunlight, rain or snow
6	WSMKSZ 13 in, 2 pack	13 inch	No reservoir; drainage holes with rubber stoppers	Indoor and outdoor use
7	SQKH 12 in, 2 pack	12 inch	Self-watering reservoir; no interval stated	Withstands harsh weather outdoors for a long time

Color variants: the UOUZ listing comes in black, black with brown and white with brown. The WUCEIAUU set comes in black-brown and pure black. The listings give the same bullets for each variant, so we show one card for each model.

The reservoir arithmetic

Two reservoir sizes are stated in the same units, and the difference is simple. The UOUZ reservoir is 50 oz and the CNLBO reservoir is 43 oz, so 50 minus 43 = 7. The UOUZ holds 7 oz more, according to the listing figures. The listings do not say whether the ounces are fluid ounces, so we compare the numbers as written and do not convert them.

The pot size gives a second difference. The 13 inch models are 13 minus 12 = 1 inch wider in diameter than the 12 inch models. That is a small gap, but it can matter for a plant that has grown into its pot.

Watering: what Iowa State says and how a reservoir fits

Iowa State University Extension says hanging baskets often hold several closely spaced small plants, that frequent watering is necessary especially in summer, and that on hot, sunny days it may be necessary to water once a day. Its guidance is to water until water runs out the bottom of the container, so every root gets moisture. If the soil dries and pulls away from the side, the extension suggests a tub soak of a couple of hours, and warns against longer soaks because they can cause root rot.

A reservoir is a different routine from watering from above. The CNLBO listing describes a cotton rope wick that draws water from the reservoir to the root zone. The UOUZ listing describes a wick and reservoir that move water into the soil by capillary action. The zople listing says the reservoir keeps plants hydrated for up to 2 weeks. The WUCEIAUU listing says the recessed base maintains humidity for weeks, and the SQKH and CNLBO listings describe water reservoirs. Those are the sellers’ figures.

Iowa State describes once-a-day watering on hot days, while the reservoir claims cover 7 to 14 days on one fill. Those are different situations, so the reservoir figures do not change Iowa State’s advice. Check the soil with a finger each time, and refill the reservoir when the soil is dry.

Drainage and saucers

Iowa State’s hanging-basket FAQ says that when you water from above, most of the water flows between the soil ball and the container and out the drainage holes, leaving much of the mix dry. That is a reason to check drainage on every model. The CNLBO listing describes multiple drainage holes, side ventilation slots and a detachable saucer that collects excess water. The SQKH 13 inch listing describes drainage holes between the planter and its tray. The UOUZ and WUCEIAUU listings describe mesh bottoms for airflow and drainage.

The WSMKSZ listing includes two rubber stoppers for its two drainage holes, which it says ease overwatering concerns. The listing does not say when to use the stoppers, so leave the holes open unless you have a reason to close them.

A saucer or drip-free spot matters outdoors. CNLBO says its saucer protects indoor surfaces and outdoor areas. For any model, hang the planter where the drips will not fall on a surface you care about.

Winter and freezing

Penn State Extension says roots of above-ground container plants can be the same temperature as the winter air. A hanging planter is above ground, so that point applies to it. Penn State’s advice is to go two zones colder when choosing plants for containers, to water the plant well before the soil freezes, and to provide some protection. Its warning about clay, ceramic and glazed pottery is about materials that may crack, and these seven planters are plastic.

Two listings state frost resistance: zople and CNLBO. The other five describe UV or weather resistance and, in the case of WUCEIAUU, snow and rain. None states a temperature limit, a freeze-thaw count or what happens to the water in a reservoir when it freezes. Colorado State University Extension describes containerized plants as exposed to extreme cold, drying winds and frequent freeze-thaw cycles, so a hanging planter in a cold season faces the same conditions, and the listing does not say how well any model handles them.

Size, plant fit and the lightweight claims

The 12 inch models are zople, CNLBO and the SQKH 12 inch listing. The 13 inch models are UOUZ, SQKH 13 inch, WUCEIAUU and WSMKSZ. The CNLBO bullets say the 12 inch diameter accommodates herbs, succulents, ferns, ivy, trailing vines and houseplants.

The plants named in each listing differ. The zople bullets name pothos, ferns, ivy, herbs, flowers and spider plants. The SQKH 13 inch bullets name ivy, herbs, ferns, philodendrons, succulents and flowers. The WSMKSZ bullets name ferns, pothos and spider plants. The UOUZ and WUCEIAUU bullets name no specific plants, and the SQKH 12 inch bullets name the same plants as the 13 inch model.

Several listings call the planters lightweight. The WSMKSZ bullets say the planters are light enough to hang anywhere, and the UOUZ and WUCEIAUU bullets describe them as lightweight yet robust. The WSMKSZ bullets also say the plastic reduces the hanging load and the risk of injury if a pot falls. That is the seller’s statement, and the listing gives no figure for the load.

For a plant that needs a larger root zone, the 13 inch models give more soil than the 12 inch models, because the diameter is larger.

Other ways to get the same planting

If you would rather mount a box to a rail than hang a pot, our DIY planter box for deck railing guide covers that option. If you water hanging pots from a hose, our hose attachment guide for watering plants covers the tool, which can make it easier to reach a high pot.

Feature checklist

Table 2 records what each listing states for the features that matter when you hang a planter. “Not stated” means the bullets say nothing about that feature.

Table 2: features stated in each listing

No.	Listing	Chains	Reservoir	Saucer or tray	Frost wording	UV or weather wording
1	zople 12 in	Iron chain, adjustable to 24 in	Yes, up to 2 weeks	Not stated	Yes	Yes
2	CNLBO 12 in	Rust-resistant metal chains	Yes, 43 oz	Yes, detachable saucer	Yes	Yes
3	SQKH 13 in	Chain rack, two per set	Yes, no interval	Yes, removable saucer	Not stated	Harsh weather
4	UOUZ 13 in	Two 23.5 in chains	Yes, 50 oz	Not stated	Not stated	Yes
5	WUCEIAUU 13 in	Chain rack, two per set	Yes, recessed base	Yes, tray	Not stated	Yes, sun, rain or snow
6	WSMKSZ 13 in	Triple chains	No	Not stated	Not stated	Indoor and outdoor use only
7	SQKH 12 in	Chain racks, two per set	Yes, no interval	Yes, removable saucer	Not stated	Harsh weather

All seven listings state chains or a chain rack. Six state a reservoir, four state a saucer or tray, and two state frost wording. The CNLBO listing is the only model that states both a saucer and frost wording, so it is the one to check first if both matter to you.

Reading a reservoir figure

The reservoir claims in this set come in three forms. The zople listing says up to 2 weeks, the CNLBO and UOUZ listings say 7 to 14 days, and the WUCEIAUU listing says for weeks. Only the first two give numbers. The 7 to 14 day range spans 14 minus 7 = 7 days, so a planter that needs a refill at day 7 is still inside the claim. Plan your checks for the short end of the range, because the listing does not say how the reservoir behaves in hot weather. The word “weeks” has no number, so it cannot be set against the other two claims.

Checking a planter before you hang it

Before you buy, read the listing for four things. First, the chain length, which zople states as adjustable up to 24 inches and UOUZ states as 23.5 inches per chain. Second, the hook: none of the listings states a load, so check the hook where it will hang, using a pot filled to its planned weight. Third, the drainage holes and whether a saucer or tray is included, using Table 2. Fourth, the diameter, since the 12 inch and 13 inch models differ by 1 inch. A planter that meets all four is a reasonable match for the outdoor use the keyword describes.

How we chose

We started from the ten listings in the research set. Each one has chains or a chain rack, so each is a hanging planter and none was dropped for the wrong type. Three of the ten are color variants of models already in the set, so the seven distinct models are the picks. The UOUZ listing has three colors, and the WUCEIAUU listing has two.

We compared the seven on what each listing states: hardware, size, reservoir or drainage feature, and outdoor wording. We did not use price, star ratings or sales data, because the research set does not hold them and this article does not use them.

What we could not verify

• Hook and chain load. No listing gives a load rating for the chains or hooks, so we cannot say any model will hold a given weight.
• Weight of a filled planter. None of the listings states it.
• Reservoir intervals. The 7 to 14 day, 2 week and “for weeks” figures are the sellers’ statements. We could not compare them with a measured interval.
• Freeze behavior. Two listings say frost-resistant. None gives a temperature limit, and none says what a reservoir does when its water freezes.
• The black UOUZ listing used for the card has only one bullet, so its details come from the title and that bullet.
• Stopper use. The WSMKSZ listing does not say when the rubber stoppers should be used.
• Long-term UV and weather life. The listings describe UV or weather resistance but give no period of outdoor use.

FAQ

Do hanging planters outside need watering every day?

Iowa State says hanging baskets need frequent watering, especially in summer, and that on hot, sunny days it may be necessary to water once a day. A reservoir can extend the time between refills, but the listings claim 7 to 14 days or up to 2 weeks, and those are seller figures. Check the soil by hand, especially in heat.

Are self-watering hanging planters better than plain ones?

The listings describe reservoirs as a way to keep the soil moist and reduce overwatering. We cannot confirm those claims, and the extension pages we opened do not compare self-watering and plain hanging planters. The WSMKSZ model has no reservoir in its listing, so its soil needs a hand check every time.

Can hanging planters stay outside in winter?

Penn State says the roots of above-ground container plants can be as cold as the winter air, and a hanging planter is above ground. Two listings say frost-resistant, and none gives a temperature limit. Penn State advises protection for containers, and it recommends watering well before the soil freezes.

How do I hang a planter so the water drains?

Iowa State says that when you water from above, much of the water runs out the drainage holes. Choose a model with drainage holes and a tray or saucer, such as CNLBO’s detachable saucer or the SQKH tray. Hang the planter where drips will not land on a surface you care about.

Bottom line

Choose a hanging planter whose chain and hook you can check, whose drainage suits the spot where it will hang, and whose reservoir claim you treat as a backup. Check the soil by hand, especially on hot days, because Iowa State says a dry mix pulls away from the sides and water can run out the bottom without soaking in.
