Jasmine plants not growing

I live in Seattle and planted three jasmine seedlings in April. I planted them near a chain link fence in a west facing spot that receives plenty of afternoon sun. They have not grown much at all since then. They are still green and look healthy. I gave them a dose of slow releasing vegetable organic fertilizer about a month ago (it was what I had on hand), and still nothing. Since planting, they have not even doubled in size. They are still only about 6 inches tall, and it's almost August!

We have had a very cool summer here, with it only getting into the 80's two or three times. It usually doesn't rain in the summer here, but this year it has rained at least once a week, and we've had many cloudy days (but also many sunny ones).

Does anyone have any ideas on what might be causing their slow growth, or ideas of things to try even if I don't know the cause? Thanks!

I have a few Confederate Jasmin, it did the same thing here to. Next year in early Spring, it took off and now after 3 years I have to trimm it few times a year. I use them on the trellis, to block the messy neighbor out. I have also planted 4 in the back in mostly shady area and they are doing well, but probobly will not have as much flowers as the front one because of the shade. You will see the Jasmin in the background of the picture.

As long as they look healthy don't worry about it--plants will always spend time getting their roots going first before they do much else so you just need to be patient.

Just remember this little poem regarding perennial plants

First Year they sleep (forming roots)
Second year they creep (still forming roots)
Third year they LEAP.

Thanks for the info! I was just worried that the plants weren't getting established enough to survive the winter here. I'll keep the area weeded and wait to see what happens next spring.

I would agree that your plants are OK, some plants take a while to get used to there new area especially if they have been settled in a pot then planted out to a season that has not been the ideal, however, plants have a way of adapting to there new garden with a little help.
The plant feed you used will have done no harm and had it been unsuitable you would have seen signs of that by now. As you are a bit worried about getting the plant through the winter ( I have no idea of what your zone is) it might help to add a mulch around the plants but several inches away from the plant stems, add a florist cane to the soil beside the plant and use sort twine and gather the stems up and gently tie to the cane.
Cut the bottom off a large juice bottle and remove the stopper/ cap, then place this over the plant so it works like a mini greenhouse, it will offer protection from the real cold weather and prevent the wind (if any) burning the soft growth of the plant, you will not need to water the plant but make sure you have sunk the bottom of the plastic container down so it wont be blown away or secure it with wire from say a wire coat hanger hooked over the top of the container acting like a tent peg. By removing the cap from the plastic bottle this will allow air to circulate and IF some condensation is seen, it will drop into the soil watering the root area.
Soon as the weather is right in spring, you can remove your baby green house maybe for a few hours to begin with then all-together and care for the plant as normal, just make sure the foliage is not resting on the plastic hence the reason for tying the plant to cane loosely.
Hope this helps you get your plants through the winter, I have had great success doing this to new plants till they can support themselves, so good luck, lets hope the winter is kind to you. WeeNel.
