Thomasville is a good story, Yuzuquat is an unlucky story.


Ichangquat in begin of June, two sprouts I was happy  ;D

then a few days later, a snail killed me both sprouts :-\, so I repotted the plant and now Im still hoping/waiting. I had new sprouts but from the rootstock, which I had to remove.


Ichangquat today



Thomasville today, in good shape.

would it make any sense to to grow in a 5+/- gallon pot till it is 3+ feet tall before planting in ground early spring.

6 weeks since planting in ground, a 4.5 year old seed grown Meiwa kumquat with a  0.5cubic meter canopy is starting to grow flower buds as well as foliage.  It is unlikely that animals will do much damage.

Yes, I regret not to have taken the plant into pot directly after winter for recovery. But the last years we nearly had no snails so I didn' t took that into account.
But you are right, that bigger plants have no problem to loose a few leaves or sprouts by snails.

update of citsuma Prague and Ivia, which are grown, but not so much as Sanford and Yuzu.


Sanford for comparison, about 80 cm high


Citsuma Prague


Ivia

winter preparations are starting although no freeze annonced for the next 10 days.
This time will try to make bricks arround the plants and then wrap around cocos mats. Perhaps this time I still add one or two water bottles if place is enough. And finally I hope we not get again down to 3,2 ° Fahrenheit  ;).
<br /><br />
Yuzu, last year no protection was to optimistic, freeze nearly to ground,   ( but didn' calculated to get 3,2°)

<br /><br />
Citsuma Prague

<br /><br />
Ivia

<br /><br />
HRS 899A, new try at new location (plant last year died after winter and spring freezes)

Winter preparations (first step sun protection with fleece) finished.
For Ichangensisxsinensis and Satsuma Collot a 80 Watt heating cable is installed if temperatures exceed -8 ° Celsius for several days it will be connected and additional isolating material as now on the top will be wrapped around.




the hardier citrus with sun protection. If cold spells are deeper than -10 ° Celsius for several days are announced, an additional cocosmat will be also wrapped around.
This year there is a new citrus CitrumeloxYuzu in ground, lets see how it will go over the freezing period.
Last years January to March are the periods with deepest temperatures.

While up to now our winter is not to cold, the coldest period have been 4 days with temperatures at night with about 20 ° F (-7° C).
But this is still not the end of our winter, due experiences of the last years, the most challenging months in the last years have been January and February. Today and the next days we have temperatures of 48 - 57 ° F ( 9- 14 ° C ).
Nevertheless its always interesting to gather informations about winter protection strategies in our cold climate (for citrus), so quite interesting to read the article in the link  below, perhaps also interesting for some of you.
