Title: Grafted Citrus
Post by: will2358 on June 27, 2019, 08:09:39 PM
If a citrus is hardy why is it grafted to a hardy root stock. If it is hardy to 10 degress shouldn't it be hardy to that temp without grafting?

Being grafted onto an even hardier rootstock can increase its hardiness a little more, and being grafted on trifoliate (usually the hardy rootstock of choice) can force the top into dormancy, helping to protect it from freeze damage.

Also, a rootstock that didn't suffer the slightest bit of damage will help the top grow more vigorously and recover after the winter.

Generally citrus trees on rootstocks that promote slower growth produce fruit that are sweeter with better flavor, than citrus trees growing a root stocks that promote rapid tree growth.

Some hardy citrus grow well on their own roots therefore don't need to be grafted, like yuzu.

I guess it is easier to graft then to wait years for the first flower on a seedling. Cuttlings doesn`t work reliable on most Citrus, even hybrids.
In my eyes it is simply easier.

Why do cuttings not work. I have some Lisbon lemon cuttings that I have rooted. I have never grafted before but I do plan on trying. Right now I have 2 Artic Frost satsuma and 1 Owari Satsuma. I have Changsha coming in the mail. I have less than an acre so I plan on doing the Dave Wilson High Density planting.
