Gardening Know How recommends lifting patio planters off paving or decking in fall so drainage holes can release excess water. The report says waterlogged soil can deprive roots of oxygen and contribute to rot; it does not provide trial data showing how much the method improves plant survival.
Gardening Know How recommends raising patio planters off paving or decking this fall to help drainage holes release excess water, a quick maintenance step the outlet says can reduce the risk of waterlogged roots during fall and winter. The report suggests lifting pots by about one inch and removing saucers that hold water beneath them.
The report describes the task as a short, low-cost intervention: slide pot feet, risers, a plant stand, or suitable flat stones or bricks beneath each planter. The gap is intended to give water a route out through the pot’s drainage hole rather than letting it collect at the base. The article says the job takes only a few minutes, though the time will depend on the number and size of pots.
Gardening Know How explains that saturated potting soil contains less air, leaving roots with less access to oxygen. It says prolonged wet conditions can contribute to root decay by creating conditions favorable to fungi and bacteria. In freezing weather, water held in the soil may also freeze and expand, potentially damaging root tissue. These are the report’s gardening explanations; the supplied material does not include experimental measurements or survival-rate comparisons.
The outlet recommends removing saucers outdoors and checking that each pot remains stable once raised. It says all outdoor container plants may benefit from improved drainage, with particular relevance for plants that prefer well-drained soil, including lavender and santolina. For large or heavy containers, it describes risers as a broader-support option than small individual pot feet; the support must suit the planter’s base and weight.
Keeping Roots Clear of Standing Water
The advice addresses a practical risk that can be easy to overlook: a container’s drainage hole may be present but still have little space to release water when the pot sits directly on a flat surface. In wetter weather, restricted drainage can leave the growing medium saturated for longer. Lifting the pot creates clearance without requiring a change to the plant or its soil.
The report also links the measure to protecting patios and containers. It says raising pots may reduce rings or algae marks on paving and decking and may help protect containers, including terracotta, from cracking. Those are potential benefits described by the source, not guaranteed outcomes. Results will vary with rainfall, the pot’s drainage, the surface beneath it, and the plant’s needs.
For readers with several outdoor pots, the recommendation offers a simple maintenance check rather than a promise that plants will survive winter. Drainage is one factor in plant health; plant hardiness, exposure, watering, and container condition also matter. The source supplies no comparative data establishing that lifting pots alone prevents winter losses.

Why Fall Changes Pot Drainage
During warmer, drier periods, the Gardening Know How report says water may evaporate more quickly, making pots sitting on paving less likely to remain wet. It presents increased fall rainfall as the reason to revisit that arrangement: water can accumulate when a container’s drainage opening is pressed close to the ground or another flat surface.
The recommendation is part of the outlet’s Weekend Win gardening series and is framed as a fall container-care task. It does not call for repotting or buying a particular product. The article lists pot toes, pot risers, and plant stands as options, and also suggests using suitable materials already on hand. It advises using at least three pot toes per planter and more for larger pots, while noting that risers can provide broader support for heavier containers.

How Much Protection Pots Gain
The supplied report does not name a publication date, cite horticultural studies, or provide measurements of how much raising pots changes drainage or winter survival. Its claims about root damage and the benefits of pot risers are presented as gardening guidance, not as quantified results.
It also does not specify a single riser type for every container. The right support depends on the pot’s size, weight, base shape, and the stability of the surface. Gardeners should check that the container cannot wobble or tip and that the drainage opening remains unobstructed. The recommendation is aimed at outdoor patio pots; the report does not set out separate instructions for indoor plants or every climate.

Check Pots Before Wet Weather
The immediate step in the report is to inspect outdoor planters before wetter fall conditions continue: remove any saucers that retain water, clear blocked drainage holes, and raise pots on stable supports. Recheck the setup after placing each container, especially for large or top-heavy plants. Use supports suited to the planter rather than assuming every pot toe or lightweight riser can carry its weight.
The source gives no follow-up test, deadline, or further announcement. Gardeners can monitor whether water drains freely after rain and adjust the support if a pot remains unstable or its base still sits against the surface. The report’s central point is a preventive maintenance recommendation, not a guarantee of winter survival.

Key Questions
How high should outdoor pots be raised?
The Gardening Know How report says about one inch is enough to create space beneath a planter for drainage. The pot must remain stable, and its drainage hole should not be blocked by the support.
Should I leave a saucer under a patio pot in fall?
The report recommends removing outdoor saucers because they can hold water around the pot’s base. It does not provide separate guidance for every plant or watering setup, so gardeners should account for local conditions and the plant’s needs.
Can I use bricks or stones instead of pot risers?
Yes. The source suggests using suitable flat pebbles or old bricks as alternatives to purchased pot toes, risers, or stands. Any material used should support the pot securely and leave its drainage opening clear.
Will raising a pot guarantee that the plant survives winter?
No. The report presents improved drainage as a way to reduce the risk of waterlogged roots, not as a guarantee. It provides no survival-rate data, and a plant’s outcome also depends on factors such as its hardiness, exposure, watering, and container condition.
