Things Needed
The satsuma mandarin orange – a tangerine tree which originated in Japan – arrived in the United States as observational planting caudex in 1878 . Well adapt to the semitropical part of Japan , the satsuma orange grows in regions of the United States too cold for other citrus fruit . When grafted to cold - stout trifoliated orange – a thorny shrub with bitter fruit – the satsuma live on wintertime minimums of 15 to 18 degrees F. Because satsuma oranges do not produce well in the hottest climates , commercial growers define output to the northern part of subtropical America . Outside that narrow-minded lot , household agriculturalist could still see regular crops from this hardy citrus tree .
Step 1
Chip - grafting satsuma orange scion to trifioliate orange rootstock in natural spring . In southerly growing regions bud grafting succeeds best from February to May . Collect healthy green twigs of satsuma orange as scion material .
Step 2
Make a horizontal gash on the trifoliate rootstock 8 to 12 inches above priming coat story . Cut straight across one side of the fore through the barque and cambium bed to the sapwood . The cut should be no longer than one - third the diam of the stem .
Step 3
Make a vertical cut downwards from the start cut . Cut through both layers of bark and make the cut 1 in long . utilise the decimal point of the knife to softly pry the corners of this MT - shaped baseball swing away from the sapwood .
Step 4
Select a satsuma orange bud from last yr ’s Sir Henry Wood . pick out buds just below the first new wood of the time of year in parliamentary law to employ the most vigorous scion material .
Step 5
slice up through bark and wood under the satsuma bud , starting 1/2 in below the scion bud and ending an inch above the bud . Cut the chip free of the sprig with a straight cutting across the twig at the upper terminal .
Step 6
Slip the bud under the bark , conform to the straight top of the carapace - mould Saratoga chip against the horizontal part of the T - shaped barque nick .
Step 7
Wrap the graft above and below the bud with grafting tape , prophylactic bands or electrical tape recording . Cover all edges of the wound .
Step 8
Remove the wrapper when the bud grafting heals – about 3 to 4 weeks in the spring . Cut through the wrapping carefully on the opposite side of the stem from the grafted bud .
Step 9
trim the top of the rootstock back to between 12 and 14 inches above the graft after the graft wholly cure . Do n’t clip off leaves or shoot on this short section of nursery branch until the graft bud grows several leaves of its own . curve the nursery branch off 1/8 in above the graft when the new scion shoot shows vigorous growth .
Tip
utilize only trifoliated orange rootstock . off-key orange tree – another plebeian rhizome – stunt scions of satsuma . Graft to rootstocks or branches of 1/2 in to 1 inch diam .
Warning
Where Satsuma orangeness trees could be killed back by wintertime cold snap , cover the rhizome and grafting junction with mounded soil in late fall . If cold conditions kills the orange tree back to soil stage , both scion and rootstock should survive .
