Annual Flowers for a Raised Bed

10 years ago

I am growing annuals in a raised bed. In the past two years, I grew marigolds. For some reason the stems dried out and looked unhealthy.

Please suggest other annuals that I can grow that will get about 12 inches tall and stay healthy all summer.

thomas.. it would be better.. if you figured out why they failed.. rather than moving on to something else ...

marigold is near bulletproof ... so i wonder what went wrong ...

i suspect improper watering.. or poor soil as backfill in the raised bed .. and do note.. one is a function of the other ...

you didnt happen to take any pix of them .. this summer??? .. if so.. post them.. and maybe we can help ...

otherwise... buy one of everything offered in spring.. and experiment.. with them all ...

growing seed of one kind.. it will take you decades to find the perfect plant...

more info.. if you want more help ...

otherwise.. simply google 12 inch annual flowers... and you will get long lists of possible plants ...

it would help to know what big city you are near ...

Michael, I'm one of those who won't grow marigolds anymore. Perhaps it's more of a southern issue, but marigolds are enormous spider mite magnets for me....hopelessly so. Plus, there's that deadheading thing. I don't do deadheading, anymore, lol.

I'll recommend little Zinnia angustifolia, one of my stand-bys year in and year out. It's very easy to grow from seed and will absolutely for you from spring until the first heavy frost.

Though it only comes in white, yellow, and orange, the colors are sparkling bright all season, never fading or getting tired looking in the hottest part of the summer.

( For some reason, I'm assuming that your beds are in the full sun, but that may not the be case. Let us know.)

Raised flower bed question

If you don't want to undo all the work you've already done - another solution is to pile up a deep layer of good soil on top of your raised bed. You can smother the grass and rot out the thatch and roots, but not with 3 inches of soil. It would have to be a foot deep at least and you wouldn't be able to plant anything for a year. Not only is there grass turf under there but plenty of weeds and weed seeds, so everything is going to spring to life in a mad dash to overtake your mound of good soil. Smothering all of them means burying under a deep layer of soil and mulch or turning the soil/mulch like it is a compost pile and let nature break down all that matter. If you don't want to wait then you have to remove what you've done and start over by either killing the grass with chemicals or digging it out. No matter what you do, weeds are going to show up in this bed anyway, so you'll be doing a lot of work either way. Weeding is a part of gardening. A battle that never ends. But if you start out right you can keep things under control.

What is the "wall" material and construction method. If it is leaky, you wouldn't need to consider drainage. I would add some type of drainage for any wall tall enough to fall over. Much depends on what it is and how you build it. What you need for a base also depends on that.

Wow -- that's a beautiful planter! I would do something like in the first example you posted; soft leafed yuccas, and some sort of hardy palm, or what ever is similar that would not die back in winter. Someone from your area can probably give you names of specific plants. And then for summer color plant something that will take reflected heat like plumbago, as suggested above, portulaca/purslane, gomphrena and such. I'm surprised at well my Serena angelonia are doing in all day sun including blast furnace afternoon sun. You probably know to use mulch to help keep the soil cooler. Also be aware that you are probably going to have to water the planter every day in the heat of summer. Eventually you may want to install drip irrigation there. Check out Texas Superstar Plants for more ideas. Good luck. It's going to be beautiful.

Yes I did some internet research and I thought it could have been spider mites.

I grew zinnias and they were beautiful but the leaves kept turning brown. Thanks for your comments. I will follow up on them.

Thomas, as you probably know, there are many, many different kinds of zinnias. Some are notoriously susceptible to diseases but others are happily carefree. Any plant that I grow has to be adaptable to the hard clay soils native to this area.

The little zinnia I mentioned is a baby rock star, as far as zinnias go.

I want some of these Zinnias too!

Having any single plant look good all summer at a certain height is very tricky, especially in a long growing season like where you are (7b.) I don't think there's enough info here to suggest much. How's the soil? Does it tend to stay dry or moist? Do you want to water, or neglect? Would you be interested in occasional trimming to keep plants a little shorter? Also assuming full sun.

Purpleinopp., I do not want to water very often, the raised bed is in full sun, and I do not mind some trimming. The soil is excellent.

You have a good point. I should be looking at several annuals the stay about 12" high.

Some that I have had very good results with here in east Central MS are: Zahara, Magellan, or Profusion zinnias, Angelonias (Serena and Serenita are easy to start from seeds), Cataranthus (Vincas) of all kinds and sizes, Gomphrena, especially Buddy, Victoria Salvia, lantana (sometimes perennial). I love Marigolds in the fall. I start them in pots from seed the first or second week of July. They go into beds to replace things that are pooped (usually because of not getting a mid summer cut back) in late August or early September. They bloom non stop until frost in November. I have never had problems with spider mites on them at that time of the year. And yes, they do need deadheading, so I don't overdo the number of plants I put out. Their colors just work so well for fall, so I am willing to pay the price.
You probably know, but just in case you don't, use a good organic mulch on your beds to minimize the amount of watering the plants need. Keeps down weeds too.

Could your soil be TOO "excellent"? I have burned both zinnias and marigolds with overfeeding. Too much nitrogen and dry soil is rough on any small flower.

Hi Thomas,

Growing in a raised bed is also similar to growing in pots. Nutrients get used up more quickly and many annuals, due to their free and heavy flowering nature require A LOT of feeding. Once a month is standard in garden beds, but in containers or raised beds you might have to feed twice a month. I suggest Jungle Flora. It has always worked really well for me and is safe to use anywhere!

You should probably also test the pH of your soil and amend it as needed.

Enjoy your garden!
