My Poncirus trifoliata is blooming today.....early due to a warm winter and spring.

Very nice Tim! Did you plant it yourself and, if so, how old is it?

Very nice, have you tried Flying dragon. It is unusual with the crooked thorns.

wow
I thought that they took a long time to come out of dormancy??

The Poncirus was seed grown from 2004? or so. Last summer was it's first year to set fruit. I planted it outside in it's second year of growth. It was less than 1 foot tall when I planted it outside.

I have not tried flying dragon yet........I need to find some seed!

Plants are blooming early this spring since temps have been so warm. Any citrus blooms for you Frank?

my satsuma is very close................that is it lol
I am colder than u!

I have P. trifoliata growing southern Vermont. The altitude is 1200 feet, so it may be colder than zone 5A.

The plants are growing all over the place, and they do well in some locations, and fail in others. The most important thing seems to be keeping them away from the wind. The best grow in a hollow surrounded by large trees. They get several hours of sun in the winter there, but seem to be able to tolerate it.

The Arnold Arboretum has P. trifoliata growing in dense shade at the bottom of a hill, so it may be a matter of keeping them from desiccating in the winter and not as much a problem with low temperature.

I am in Vienna, the capital of Austria in europe.

I know of 4 Poncirus trifoliata, that survived - 28 ° C last winter.

You just should grow it AT LEAST 4 years in a pot before plant it outside.
The longer you keep it in a pot and take in when it´s freezing, the better.

I planted outside three PT seedings I germinated this spring......this will be a nice test to see how hardy they are when young.

I think they will die without protection.

I think the PT seedlings should have a decent chance of survival. A couple years ago I planted a small FD outside. It was probably only 8-10 inches tall at the time, which may be a bit larger than your seedlings. I haven't seen any twig dieback and it was nearly evergreen the first winter, retaining 50-75% of its leaves. This past winter it held on to 10-15% of its leaves. Since we are in a very similar costal MA climate, I wouldn't be surprised if they are fine. Of course, this being MA, I also wouldn't be too surprised if they don't make it. How big was your large PT when you planted it, it really looks like it's doing well.

It will be interesting to see what happens with the seedlings.

Here is a pic of my FD, now about 2 ft tall. It has seen 3 winters and has never been protected.

I think they just have a chance when being covered at frost.

Leafes, soil, snow ... anything ...

Seedlings of Poncirus are very cold hardy. They only become weak when they are grafted and when the graft bears fruits.

It means they are very resistant when they are dormant. When there is a call for sap (new flush or fruits) they are weak.

My PT was planted outdoors in its second season. The first winter I kept it in the unheated garage. I believe I received the seed back in 2004 so I planted it in 2005.

I'm sure our winter snow's will help it survive when young.......unless we don't get much.

PS, your FDPT looks great!

Tim, that is a great looking tree. How tall is it?

Does anyone know if there are vigor differences between cultivars. I have two sources for my plants. Some were older when planted than others, so I can't tell if it is age or type that has made a difference in growth.

Also, I have sown them directly in the ground, but lost most of them to wildlife. They were hardy in Vt. from the start
