Title: Rooting cuttings
Post by: Zarafet on August 15, 2017, 09:17:28 PM

Has anyone tried rooting cuttings from CCPP? If successful, what was your best technique?

I have rooted CCPP cutting after I have used the buds I needed.  Do not skimp on quality of the ingredients for the rooting medium  Oxygen is necessary for root respiration at all times, but oxygen plays an even more critical role in the initiation of new roots on a cutting.  For example, for rooting of cuttings, drainable pore space in the medium should be 45 to 50 percent.   Once the cutting has rooted drainable pore space in the medium should be about 20 to 25%.   Use a container with a depth NO less than 4 inches.  There is no ideal rooting medium, but several combinations of materials can provide a good workable medium with a drainable pore space of 40 to 50 percent.  Good quality peat and coarse perlite, or peat and ground pine bark, on a 1:1 or 1:1.5 or 1:2 basis by volume works well in propagation containers approximately 4 inches deep.  CLEAN, CLEAN CLEAN.

Thanks boss. Did you remove the cambium layer at the lower inch to allow roits to grow from there?

I wound all cutting that I root, by scraping a line about 1 inch long at the cutting bottom.   One note, a cutting must have energy in it to root well,  weak skinny cuttings generally do not root.

It's the (only?) source of clean budwood in California. It's illegal to get budwood from anywhere else for those of us living in citrus ACP quarantined states.

I have been able to get it to work, but it was difficult. I am planning some more experiments. I wrote an article about it here:

A small greenhouse with bottom heating set at 23C, humidity 90%, use of IAA 2g/l and NAA 0.2g/l will give you roots in 2 weeks. Potting mix should be 1 part vermiculite, 1 part peat. Sterilize the peat at 121C, 15 psi for 15 minutes. Vermiculite should be sterile.
This is what I do, success rate 100%.
