Thanks for that detailed reply to my question regarding propagating zucchini. I live on Koh Samui, Thailand where everything seems to thrive in the ground. I’ve attached two photos of the zucchini plant I was referring to. Could you please indicate, with the help of my photos, which section of the plant I should try to graft? Many thanks and kind regards Bronwyn

You will, first have to prepare a vine with a few leaves on them. These will die off before they are rooted, but having them will give them some energy to make an attempt at rooting. Then you need to prepare about 20 to 30 cm of the vine by stripping off all flowers, and keeping them off. Flowers will prevent rooting, as this hormone inhibits this action. It is important to note that the stems are typically hollow. This poses most of the issue with rooting. Whenyou cut the segment off, you will want to apply the methods mentioned before. Make sure to keep these covered to raise humidity, and remove the leaves as they dry up. If you do not have roots before the entire vine dries up, then you will have to try again. Most attempts will be unsuccessful, so be prepared for this.
Now, on some occasions the plant may root a portion of itself down the length of the vine. If this happens, then digging us that small rooted portion will do the rooting part for you. You will then be able to transplant, and treat it as a young plant. If this person will let you dig up a portion then this will be the best method. If these are not available then you will have to try rooting a branch.
If all else fails- go for a seed on the best looking fruit. It may not be the same, but it can get close.
