So, I am trying to root some cuttings and I am looking for some guidance...
I have cuttings from Thompson Seedless and Flame grapes, Wonderful pomagranates, kadota fig, and several different types of southern highbush blueberries.
Everything but the blueberries were taken from dormant wood cuttings. All that was available to me for the blueberries was green softwood cuttings.
I used a rooting hormone and put them directly into a moist growing medium in pots on my potting station that gets filtered sunlight throughout the day. I am keeping the pots moist. I have not put a plastic cover on anything because I was worried that they would fry. So far everything seems to still be living, but nothing has rooted yet. They have been in about 4 weeks.
How long do I wait before I know if they are going to root? Should I pull them and try to root them in a plastic bag with a moist paper towel?
I root my fig cuttings first wrapped in wet paper towels and placed in a ziplock bag. It usually takes a few weeks or so to root. Then I put them in a soil/perlite mix to continue developing. I did this last year and they grew fine. I tried just putting them in the soil and that didn't work for me.
Thanks Cricket. I think I will pull them and try that!
Are you giving away cuttings again this year?
If I have luck with them rooting I should have a bunch. I have black mission, and 2 types of green fig (probably Kadota and Conandria, I might be able to tell better after they leaf out.) I will post here if I have some to share! Was hoping to have them ready for the seed/seedling swap, but it doesn't look like they will be ready in time. ;(
I've had better luck in getting cuttings to root by increasing the humidity with a clear plastic "tent" over the pot. A bag from the produce department works well. You can support it so that it does not touch the cutting with 2 or 3 chopsticks (or branches for longer cuttings) stuck into the soil of the pot. Bottom heat can also help. If you don't have access to a soil heating cable, try using an old heating pad set on low. Set the pots on the heating pad but be very careful about watering. You will need to check soil moisture levels more frequently. Also, you may want to put the heating pad on a timer so that it is on only at night since it has been warm during the days. The blueberries are tricky, so don't be too disappointed if the success rate is low. You should have good root formation with the others. Let us know how things work out.
Either way should work as long as at least one bud is present on the cutting and it never dries out. You seem to have done everything well.
With regard to blueberries, remember that the soil must be around a pH of 4 to 5.5. And they like a lot of uncomposted organic material present... though I doubt that would effect rooting. They are also sensitive to one or two molecules that are relatively common fertilizer ingredients that should not be present...can't remember what they are but I think aluminum sulfate used to lower pH was one.
I know that blueberries are sensitive to pH and nitrates...hadn't heard about aluminum sulfate. Like you said, it shouldn't affect rooting as much as the development of the plant. I am going to move these into a rooting bag and see if I get better results.
I used the method found here for rooting fig cuttings and the results were amazing. I had rooted cuttings ready to plant in about 2 weeks, I gave some to a friend which he planted directly in the ground and his produced a good quantity of figs at about 7 months after planting. http://figs4fun.com/Rooting_Bag.html
I also acquired pomegranate cuttings which were wrapped in damp towels, put in a bag and refrigerated for about 3 months. I also put them in clear cups in the same potting mixture from the fig site and got two of maybe half a dozen to root and grow. I like using the clear cups so you can see root development.
I have no experience with grapes or blueberries. Good luck.
Judy, so it sound like figs are pretty easy to root, but that pomagranates are harder... Yeah, I aquired a few more fig cuttings, from 3 different types of fig and I am going to try rooting them in the bag as that site shows and I will compare to the results I get from rooting them directly in growing medium. Love an experiment!
That's the only way to find out, experiment! I just read that grape cuttings should be planted in good fertile soil with half the cutting buried and keep well moist. Hope they work out for you.
Fig, filbert, olive, pomegranate, gooseberry, bramble, grape and mulberry can be grown well on their own roots...no rootstock needed. All should do well as a cutting, except gooseberry and filbert nuts are unlikely to fruit here (too hot and not enough chill hours (800) respectively).
On the issue of rooting olives, my neighbor has a few olive trees with TONS of shoots coming off it. What's the best way to remove those from his tree (with permission) and make a tree grow in my yard?
