A galvanized planter is easy to use and maintain, making it an efficient and cost-effective way to grow plants.
It can be used for both indoor and outdoor gardening. Its small size also makes it ideal for apartment dwellers with limited gardening space.
Creating a unique container gardening idea, old vintage galvanized planters can be loaded with annuals or perennials, forming a brilliant season-long vivid arrangement.
Placed on the front porch or in the yard, galvanized planters are beautiful in any location.
At the very end of March, flowers filled the greenhouse tables with vibrant colors of annuals tucked in tiny black planters. I knew, living in Missouri, I was taking my chances that tender annuals could be lost to a cold frosty morning.
The long dark days of winter had lingered, and the charming warmer days of spring had me desiring to plant all the growing things.
One particularly sunny day, I strolled through the large front door of a local greenhouse. I was greeted by an employee who remembered me from years past.
“Here for the white geraniums and black petunias,” she asked.
“Yes, of course,” I answered with a smile and chuckle. She led the way down through the gravel walkway, pointing out just what I was on the hunt for.
I gathered a box from the top of the shelf and filled it with tall white geraniums. Then, walking back to the front of the store, I placed my box on the corner of the small store counter.
Up and down the gravel walkway, I wandered, reading tags, picking up plants, putting them back, making decisions for just what I wanted in each of my old flea market find washtub planters.
Eventually, I paid for my purchase, and with the help of the store employee, we loaded the plants in the vehicle, and I headed for home. Shopping for plants is a great idea any day and is like therapy for my soul.
Arriving home, I unloaded all of the plants and sat each box on the ground. Then, standing back, I admired the combination of plants that would spend the summer thriving in old charming washtub planters as rustic decor for the garden.
I arranged and rearranged the potted plants with joy until I was satisfied with how they would fill, spill, and thrill inside their new home for the season ahead in my garden space.
Below, I have shared detailed information on my thought method as I plant flowers in old metal buckets or better known as wash tub planters. As well as sharing which flowering annuals and perennials are used in the metal tub containers.

- Potting Mix: healthy soil matters, and when planting in containers, use a high-quality potting mix. The Organic Potting Mix I use is a mixture of peat moss, composted bark, and perlite.
- Gardening Gloves: while not a necessary item, gardening gloves help keep dirt from under fingernails.
- Wash Tub Planters: Gathered over the years from yard sales, flea markets, and antique shops and passed down to my grandmothers, my collection has grown. I have a double square wash tub planter with sturdy legs, two round wash tub planters on stands, and several single squares and round ones. Washtub reproductions can be found online in various sizes and styles.
- Plants: depending on the size of the galvanized planters, plant annuals, or perennials in the container. I share some of my personal beloved plants farther down in this post.
How to Make a Galvanized Planter
Large and long-lasting, galvanized planters, such as old wash tubs, make my favorite projects for container gardening easy with these easy-to-follow tips.
Once galvanized tub planters are filled with potting mix and flowers, they will be heavy and burdensome to move. Before filling the washtub, consider the needs of the flowers.
Do they need shade or sun? Plan accordingly, and place the large galvanized tubs where you can enjoy them all season long.
Most of the old galvanized tubs that I have acquired on flea marketing adventures or passed through generations already have large drainage holes in the bottom.
Without proper drainage, plant roots can rot, causing the plant to die. If there are no drain holes, drill a few small holes in the bottom. The holes only need to be large enough that allow excess water to drain out the bottom.
Add potting mix, which is specifically designed for planters. To reduce the amount of soil needed to fill the container, add rocks to the planter’s bottom before adding potting mix.
However, when planting perennials in old galvanized tubs, fill it full of the potting mix so that the plant has plenty of soil to root in.
Advice for Planting in Galvanized Tubs
Sun or Shade
When purchasing flowers for planting in galvanized tub planters, consider the needs of the flowering plants.
Reading the labels will help to distinguish if sun or shade is needed and the amount of water each one will need to receive.
A wide assortment of colors and textures are available to choose from for planting flowers in containers. In years past, I have used all white flowers.
This year, I chose to combine black, white, and a bit of purple. Proven Winners shares an informative post on color design ideas.
My preferred way of planting flowers is the “Thriller, Filler, Spiller” method.
Thrillers are plants that add height. Spillers drape over the edge of the container, and fillers make the container look complete.
Save Plant Tags
Tuck plant tags into the soil at the back of the pot or store them in a place that is easily referenced back to.
This helps identify the plants during the growing season and what you may want to purchase or not purchase the next year.
Growing flowers in galvanized tub planters require feeding. I have had great success using Oscomote Plus at the time of planting.
When planting, add 1 teaspoon for each bedding plant-sized plant. For a 4″ pot, use 2 teaspoons.
Work the fertilizer into the hole with the dirt and then plant. Water and rain will slowly release the fertilizer and feed the plants all season long.
To keep flowering plants looking pretty through the seasons, remove broken leaves, and spent flowers. If the plant gets leggy, prune it back.
Watering will be essential during the blazing days of summer. Flowers growing in galvanized tub planters will dry out quickly, and many times, the flowers will need to be watered on an everyday basis.
How Do You Plant Flowers in an Old Galvanized Tub?
Clean up Annuals
Before planting, remove any dead leaves or flowers on the plants. If any weeds are present in the flower pots, remove them before planting.
Slide Plants out of Pots
Tenderly slide plants out of the pots by pressing on the sides of the container. Never pull the plant straight out of the planter as this can break off stems and damage the plant.
Loosen Plant Roots
Roots can become bound if the plant grows in the container for a long time. This will cause the roots to grow in the shape of the container and be bound around in the soil.
To loosen the roots, use your fingers to divide the roots. This will help ensure that the plant begins to root properly in the washtub planter.
Tuck Plants in the Soil
It is always a good idea to tuck the plants into the soil at the same depth originally planted in the pot. Add the soil around the plant and lightly firm the soil down to keep the plant upright.
After planting, water the plants in the container. Use a watering can to gently water the plants as a garden hose can apply too much pressure, resulting in damage to the flowering plants.
It is essential not to let the soil in washtub planters dry out completely. Adding mulch one inch from the base of the plants will help to preserve moisture.
How do You Arrange Plants Planter
Arranging flowering plants in a washtub planter will depend much on particular preferences. When potting plants, the reality is, that plants are highly versatile, and there is no “right” answer.
Nevertheless, here are a few considerations to consider arranging those plants for the greatest impact.
Plant by Spacing Suggestion
Examine the data on the plant tag that came with the plant. Plant flowering plants in the container by the suggestion on the tag to allow for enough space.
Planting where enough spacing is given among the plants requires patience while waiting for the planter to look extravagant.
In addition, plants are commonly healthier in less crowded containers as greater airflow is available, allowing the foliage to dry more quickly, helping to limit disease.
Crowd the Plants
Putting as many plants as possible into the container is another idea for arranging plants. In doing so, the planters look complete instantly.
This is often a great plan if you need a container planting to look wondrous right away.
Yet, if not given enough room, the roots can become restricted or have more disease problems from reducing airflow amongst the plants.
How many plants are placed in a washtub planter may depend on the spreading habit of the plant? Some types spread quite vigorously, growing swiftly and overflowing in the entire planter.
Other types are more compact and have upright characteristics, which may require more than the suggested amount to make the planter seem full.
Thrill, Spill and Fill
Thrillers are frequently placed either in the center or at the back of a container. Thrillers are plants that add height and an upright element to the planter combinations.
Fillers are essential for making planters look full and placed in front of or around the thriller plants. Spillers are placed at the edge and spill over the side of the planters.
Galvanized Planter Ideas
Flowering annuals and perennials can be planted in old vintage wash tub planters. For wash tub planters filled with annuals to remain charming all season long, look for annuals that bloom all summer or have foliage that remains attractive.
Hardy perennials and compact shrubs can also be planted in washtub planters and will grow back from year to year.
Utilizing perennials helps curb the expense of purchasing annuals each year and some provide year-round enjoyment.

While there are many annuals available to purchase in garden centers, these are the plants that I seem to be drawn to year after year. So, here are some washtub planter ideas for annuals.
