They are impatiens of the pointy leaved variety, and will become half wilted and look depressingly vesicular within a week, because that set up doesn’t offer partial shade and even if it did, they would look awful and then die after looking grotesque and clammy, even if perfectly cared for so it doesn’t matter. Nothing you can do will ever fix the gloom of impatiens. Nothing. You invested in despair.

Btw that’s an astonishing waste of $235 dollars at the home and garden store assuming you bought the impatiens on discount since they are usually on discount now.

It’s fixable.
Next season start a month or so earlier and carefully while wearing gloves, eye protection and a breathable face mask, along with a long shirt and leg coverings, use grass killer on the fence row grass seen behind that concrete lined veil of disappointment that you have there.

You’ll want to kill the grass growing in your yard by your fence to make a no-dig border garden. To do this, begin 6 weeks to a month before going to the garden store, by killing the grass on your side of the fence only, in a border beside the fence that is the size you want to turn into a no-dig garden.

Then while you are at the home and garden store, you will buy radish seeds in a packet of radish seeds, and a packet of zinnia seeds mixed with fertilizer and vermiculite, plus a packet of wildflower seeds mixed with vermiculite and fertilizer, a pair of gloves, and a few bags of the same color mulch. I recommend dark brown natural wood mulch for beginners. Red mulch is usually a mistake. I know you want to use the red mulch but consider that dark brown mulch will be forgiving of mistakes and try it my way first this time.

Once you arrive home where you have already previously prepared the fence row border by intentionally killing the grass on your side of the fence in the size border you want for a border garden, you will place newspaper or cardboard at the edge of your border garden to be on top of the dead grass in a tidy shape. Then apply mulch only to the cardboard. Then throw a few handfuls of mulch into every square meter of dead grass.
Then use a bowl or bag and mix your radish, zinnia, and wildflower mix seeds together, and then broadcast sow (this means evenly throw small handfuls of radish seeds mixed with the premix zinnia and wildflower seeds) over the dead grass area where there isn’t any mulch and water it every day for two weeks then 1/2 weekly. After three weeks you will add a handful of mulch wherever there aren’t lots of tiny green plants growing including where there’s already some mulch just to make it look extra posh.

And btw there’s no point in keeping multiple bird baths full of water.
Birds like food and gardens, not grass, they will not like your yard enough for two bird baths worth of bathing and birds do not segregate when bathing.
Using two birdbaths won’t fix the lack of a bird friendly garden either, although you can fix that by following the above instructions.

Instead of maintaining two birdbaths, although that displays a healthy and optimistic attitude towards bird hygiene, use one of the birdbaths for a birdbath and the other for a bird feeder displaying birdseed by drilling a drain hole or several to keep it from being a birdbath, and then set it up as a feeder using a small plate for the fresh seed and small pieces of fruit, and possibly spoonfuls of jelly that you’ll want to put out every three days conveniently at the same time when you water your new garden and while you refresh the remaining birdbath with clean water.

It appears by the pic that your probably depressing landlord said in the contract that there is to be no digging and on request for exemption suggested you choose impatiens in pots instead of having a garden.

Word to the rebellion.

It’s not digging if you first used grass killer on your grass (or to be environmentally kind, apply a cardboard or black plastic cover to the area you want to turn into garden, in order to remove grass, at least a month prior to going to the home and garden store) and then you by broadcast sowing which means tossing out very small handfuls of plant radish seeds (buy a packet of them) mixed with zinnia and wildflower seeds purchased in those package mixes complete with fertilizer and vermiculite. So you can fix it and then you’ll at least have butterflies if not two birdbaths worth of birds, and any weeds that appear you may truthfully call wildflowers that are very good for pollinators.

The depressing landlord can argue that it had to have been dug, because it will certainly grow into a garden like thing that other lesser mortals might have to dig to attain but you did not (if you follow the above instructions), but your landlord will probably fail at the argument if you save receipts (to expedite this saving receipt process, take photo of receipt and of the no-dig garden purchases and send the photos to an online email account where you will archive the project as “garden receipts and photos) to avoid losing the receipt for possible inquiry by landlord) and also take (and similarly save/curate) photos of the garden creation process as outlined above.
No digging is needed if you follow the above instructions.

The radishes are a surprising tool for subversive gardening because they will form a radish root and also send up a tall flower that if you don’t harvest the radish root will grow then produce attractive and edible seed pods in the warm months, and when the plant fades it will eventually leave holes where the radish root had been, that will stay as radish sized holes and next year you can fill with sun loving seedlings, all without using a trowel. It’s called bio-drilling and everybody who is anybody is doing it. You can be cool like that too. To be a step cooler you might purchase a mix of Daikon, horseradish and smaller radish seeds to mix into your zinnia and wildflower mixes, because the daikon and horseradish seeds will produce larger holes for varying sized seedlings all without using a trowel or committing any digging.

You’ll never need to buy impatiens again: you will have flowers all summer into the autumn and will have a garden with interesting winter seed pods for the birds to discover if they actually do venture that far into people box land.

Since you’ll want to remove that horrible concrete structure after realizing that it’s horrible, you can easily reuse the blocks as a stacked side edging (not front edging) (as a small wall effect, at the height for sitting on as you food harvest the radish seed pods that you’ll recognize on how to safely harvest them and not mistake them for an inedible seedpod, after researching it) for your upcoming “by the fence, as a lovely border, instead of grass” garden. The concrete will make it look slightly more intentional, and give you an extra classy pillar on which to esteem the plaster garden gnomes and flamingos you will buy with your newly freed garden budget (along with dark grey pavers and a pair of garden gloves, plus concrete glue with which to follow the instructions while wearing gloves and eye protection, to affix the dark grey pavers to the concrete block top edge (before placing the delightful plaster decorative ornaments your whimsical nature demands), as to hide that traditionally fashionable yet possibly not entirely practical concrete block hole pattern.

That is all.
