Clethra Alnifolia Germination

I’m trying to get a pkg. of summersweet clethra to germinate with no success. I have tried 3 inch peat pots and now getting ready to use a plant bed. What is the secret to getting it to sprout?

You would probably have better luck with taking softwood cuttings from the plant instead. This article will help: https://www.gardeningknowhow.com/ornamental/trees/tgen/how-to-root-cuttings-from-various-shrubs-bushes-and-trees.htm

When Do I Plant Clethra Alnifolia Outside?

We just purchased a clethra shrub and are wondering if it should be put in the ground right away. It is currently late September and we live in Maine, zone 5b. Would it be better to keep it indoors until spring? The shrub is 4 feet tall and 21 inches wide.

With proper care and protection, fall planting is fine. However, as long as it;s in a container and kept in an unheated area, like a garage or basement, you may be able to overwinter the shrub as it will need to enter dormancy. This article should also help with its care: https://www.gardeningknowhow.com/ornamental/shrubs/summersweet/summersweet-plant.htm

Summersweet Shrub Never Blooms

My summersweet shrub is very healthy, but never blooms. Any suggestions? The summersweet has been in my garden for at least 6 years and has never bloomed. It gets dappled shade most of the day with maybe a little direct sun in late afternoon.

You may want to have a soil test preformed as it does like the soil to be slightly acidic.
Here is a link that should help you pinpoint the issue.

Hummingbird Summersweet

Seems like I didn’t water my Clethra alnifolia quite enough during this terribly dry summer. It looks quite burnt. I’ve started to water it every other day now and I’m wondering about the chances of it coming back, if not this year, then next. Should I should fertilize at this point or wait for the spring? Should I snip the dead flowers off or leave them? Or should I just look into buying another plant and take better care next time? Thank you.

As long as the plant is not already too far gone and if it still has green, pliable branches/stems, then it should be okay, but you must remember to continue with its overall care. I would not fertilize while the plant is under stress, as this could actually do more harm than good. You can, however, cut back any dead growth and simply continue caring for it as usual. If the plant survives winter, you should begin to see new growth come spring, if not sooner.

Summersweet, Hummingbird

We have 3 summersweet, hummingbird, plants that were planted in the fall of 2016, along with many other perenials. I am not sure if they have survived the winter. There seems to be some sprouting at the base of the plants, but the branches seem dull colored and brittle. So, how do I tell if they survived?

ANSWERS

This shrub is zoned 3-9.
Check the branches, do the bend or snap off?
Dead branches will snap and break.
After danger of frost has passed, prune the dead parts of the shrub.
If your seeing new growth, the roots most likely survived and your shrub should recover.
Next winter you can add some mulch protection to the plant.
Remember, most reputable garden centers will guarantee a new shrub or tree for one year, so check your receipt if your shrub does not recover.
