How To Grow Nasturtiums In Outdoor Planters ~ Easy to grow from seed nasturtium blooms make a stunning outdoor display trailing down outdoor planters!
You may be wondering why I am posting an article about how to grow nasturtiums in outdoor planters even though it’s just the month of March and Spring hasn’t officially arrived yet. But if you’re a gardening enthusiast like me this is also the time where we start to plan our gardens. I now start to browse through seed catalogues and check out the garden shops for possibilities! I was hoping to inspire you to grow nasturtiums in outdoor planters this summer. I actually took these photographs last summer when the nasturtiums were at their blooming best and saved them to share with you now. They are super easy to grow and create a stunning effect! This how to grow nasturtiums in outdoor planters…
A few years ago I bought tall planters to stand in front of the three pillars in the lower patio. I tried several different types of annuals in these planters over several years and was never happy with what grew. Whatever I planted never got full and lush even though they had lots of sun and were watered regularly.
Then I got the idea of planting nasturtiums. They are so easy to grow from seed and they create a beautiful sunset palette with their red, yellow, orange and pink flowers. Don’t they look fabulous spilling over the tall planters? How did I achieve this look so you can too?
How To Grow Nasturtiums In Outdoor Planters
The first thing you need to know is that I planted ‘Climbing Vine – Nasturtiums – Tall Climbing Mix’ seeds. Instead of having the nasturtiums climb up a trellis or along a fence I had them grow by spilling over the sides of the tall planter. They grew so well that you could hardly see the planter.
After the seeds were planted, the nasturtiums were so easy to maintain. They’re drought tolerant but I gave them daily watering because they faced south and it can get pretty hot in our backyard in the summer. They also got a monthly dose of fertilizer and I pulled off the dead flowers to encourage new blooms to come.
I filled the planters two thirds full with peat moss and the top third with quality potting soil mixed for outdoor planters.
I also soaked the seeds in water overnight just to help get things going.
I planted ten seeds per container about the beginning of May. The seeds can start to do their magic in the soil even though our weather may still be chilly at night. I gave them a bit of water everyday just to give them a bit of a drink.
Three weeks later I bought six nasturtiums bedding plants and planted two plants per container. You may be asking why I did that? Where I live in Canada it’s a Zone 3 growing area. As a rule of thumb we can’t plant anything till after our Victoria Day May long weekend because we still may get a night frost up until that time. I have put out annual bedding plants before that time just to have them freeze. I bought these established nasturtiums to get going so I can enjoy the planters sooner. Eventually the seeded plants caught up to the purchased plants and the nasturtium planters looked fabulous!
The nasturtiums bloomed beautifully all summer and at the end of the growing season the blooms went to seed. Nasturtiums seeds are nice large ones, easy to collect for next year’s growing season and that’s exactly what I did!
This is how one of the nasturtium planters looked up close. You will notice a trellis at the back with some spindly plants trying to grow. I also planted Red Runner Beans thinking they could grow up the trellis creating a really neat affect. That plan didn’t work very well because I think the nasturtiums took up most of the growing space, sun and soil’s nutrients.
As I start my garden planning for this summer I’m thinking I will have most of the nasturtiums spill over the planter but train some of them to grow up the trellis. If that works, it will look amazing!
Here’s a photograph I took of the nasturtiums up close for my Garden Directory I am developing. I am photographing every plant growing in my yard. If you are interested in learning more about how I am doing this you can read about it in What’s Blooming In My Garden In June? and What Bloomed In My Garden In July?.
Here are two other photographs I took of our lower patio showing the nasturtiums container gardens standing in front of the pillars. In the summer I often sit here to read with a cup of coffee in the morning or a glass of wine in the evening!
Final Comments: The back of the nasturtiums seed package describes it as an old favourite with a delightful fragrance that is very easy to grow. I so agree and I love plants like these that are low maintenance and best of all, super showy for the summer season! It is so easy once you know how to grow nasturtiums in outdoor planters!
Hope I inspired you with your garden planning for this summer! Here is another pinnable image for future reading!
