The Tropical Fruit Forum

Thank you.  I Know that every Kumquat graft had extreme problems starting growing.  They all had to have their main trunks cut before any amount of growth of the scion started.  I don't remember whether last years graft were this yellow, but I do remembering if any of them was going to live or die.

This tree has lost most of its leave.  I think I am going to put it in the unheated basemen and provide some light till spring grow time.

I have 4 varieties,  Meiwa, Fukushu, New Zealand lemonade, Valentine Pomelo.  I have grafted my own buds to different rootstocks.  CCPP is far to expensive.  I  live in Ohio where grafting of non certified citrus wood is legal.  All four of the original tree cultivars were gifts from friends.  Citrus is so difficult to grow up north of the Mandarin - Dekopon line it is not wort purchasing trees of any citrus cultivar.  Grafting is free.  go buy a Seville sour orange and you got seed to seedling to grafted trees to grow.

10F this morning. 12F tonight and mine are under 4 layers of glass with an 72 watt heater.

Mine is however a kumquat.

The tree still looks good and will go outside tonight for the 9F low.  I will remove several high branches to root.  If they truly survived 15F I will know in 2 weeks.  If the tree dies tomorrow morning but survived the 15F we will all know the limitations of full hardened NZL

Very little visible damage.  A few leaves' stem collapsed.

Tree is in position and the pot, roots and first 3 inches of trunk are insulate with cold 30F'ish leaves.

Just brought my Seed grown New Zealand lemonade tree inside So far it has seen 22F, 22F, 20F, 25F, and many hard frosts. to date. I am warming the roots up to hibernation temperatures for that of an in ground tree so I can put it back outside for the up coming 17F, 13F to determine cold hardiness of this cultivar 01-02-2022



It is now down in an unheated basement to prevent coming out of dormancy.  It has seen 2 months with most nights below freezing.

I have Ammonium sulfate 21-0-0  Do I have to worry about BIURET in my feed

Head start is everything when starting from seed.

Merry Christmas everyone and to the trees too.

Harvey lemon is reported to be able to take cold to 10F.  My New Zealand lemonade has sail through 2 nights at 20F and 3 more night around 22F and more frosts than I have fingers and toes.  I have them all still.

It is interesting to note that according to the most recent research, urine is actually not sterile.

Nothing is sterile.  That is why we rot from the inside out when we die.

Pump sprayer 1 gallon from Home Depot. adjustable mist.  Urine is premix by drinking excessive water before collecting.

Before and after a repot of my Fukushu kumquat tree on Flying dragon.  The top part is 14.5 months old since the T-Bud started growing and the FD roots will be 3 years old 1-1-22.  I guess the big question is If the roots are Flying Dragon and the top is Fukushu and I were to trim the top and transplant the roots Am I  trimming a Fukushu while transplanting a Flying dragon.
