What type of grow light is best for growing fig cuttings?

10 years ago

I usually post my questions about growing fig trees on the fig forum, but after searching this subject this forum appeared. I am rooting some fig tree cuttings, and once they are rooted I will transplant them to cups and I would like to put them under some type of grow lights indoors.
I would appreciate some recommendations and suggestions. Thanks, Terry

Terry-

Depending on quantity (like several rows or just a few starters) I would vary my response from a few CFL's to whichever sized T5/T8 setup would work.

From what I understand 6500K CFL's would do the trick for small scale starting.

Hope this helped, I'm 'newer' in this area of growing myself.

Terry,

I started a few dozen figs last year from UCDavis cuttings as well as trades.

Initially, the cuttings were put in Root Riot plugs inside 72 cell inserts in a 1020 tray (no holes) with a 7" plastic dome on top of a heating mat. (How's that for a lot of info in one sentence-like fragment?)

The cuttings don't really need light at this point (perhaps ambient light) because the point is to get roots to develop, not to grow leaves.

After they rooted, the figs were put into 16 ounce cups and kept under the dome with basic shop lights. Again, here the idea is to keep the humidity up and get the plant going.

As soon as it was warm enough, the figs go outside (keeping the humidity up until the plant has stabilized). Make sure you don't bake the plant under a plastic bottle, though. Ease them from shade into the sun over the course of a week. Gradually remove whatever you are using to keep the humidity up (such as a 2 liter soda bottle with the bottom cut off).

Any growth you get indoors is incidental for rooting. I had a great success rate on getting them started and then transferred to 1, 2 and even 5 gallon containers within the first year.

For overwintering, you can either supply them with the shop light or just let them go dormant and keep them in the dark and above freezing.

It is too bad you don't know what the fig was. I have a naturalized fig coming up all over the property that is a persistent weed. If you let the old trunk grow new growth you would find out quicker if it was a decent fig or if it would even fruit in SF. A lot of people on the coast have planted the mission fig that will only very rarely bear a crop that has time to ripen in the cool climate. Al

Matt here is a link to the spectrums if you read thru carefully its explains the different ones for sifferent stages of growth, then the last link to a site that has grow lights for different stages and bulbs . Maybe this will give you some idea;s and needed info. http://en.wikipedia.org/wiki/Grow_light http://www.specialty-lights.com/960320.html Martin

You might not want to keep the best plants in the window for very long. The lights can actually produce a more robust plant than the window, that's one reason why a lot of people use them. If you don't have enough room under the lights and need to use the window for extra growing space, I would plan to rotate the plants every couple of days from one location to the other so that they all regularly spend some time under the lights. Rearranging them periodically will also help them grow a straight stem, since plants tend to lean toward the direction that the strongest light is coming from. For your window this will be the outdoors and for the light fixture it will be the center of the fluorescent tubes, because even though you may not be able to see it, the light intensity falls off dramatically as you go from the center toward each end of the tube.

Hi Cincinnata, and thank you for your reply. Funnily enough we watched a rat make its way right to the top of a fig tree whilst out walking just the other day but I didn't realise it was such a common occurance. While spanish rats seem to be smaller and prettier than their english counterparts they are still my least favorite vermin and I certainly don't want to encourage them into my garden. Luckily the figs already planted are in the far corner of the garden well away from the house. You seem to have sized my friends Pepe and Mateo up perfectly and I am guessing you may have a few similar type neighbours! So I will try to keep everybody happy and do no more on the fig planting front.

Andrew,
Could you explain in easier terms please? I don't understand
what you meant:

"Initially, the cuttings were put in Root Riot plugs inside 72 cell inserts in a 1020 tray (no holes) with a 7" plastic dome on top of a heating mat."

My husband can help me build a light cabinet or something. Right now we just have our cuttings in cups in front of our windows for light. I think they will need more light later.

Terry,

Root Riot is a small, sponge-like 'plug' into which the cutting is inserted. This gets dropped into a tray filled with (for example) a bunch of empty 6 packs. A tray with 12 empty 6 packs would hold 1 'plug' per cell for 72 cuttings.

The cuttings don't need light initially - they need a humid environment in order to put out roots. That's what the plastic dome over the tray does - it keeps the moisture in.

If you have the cuttings in some kind of mix, that will work also - just maybe not as high a success rate in rooting.

Once the cuttings are putting out roots, you can put them into a larger container if you are using Root Riot or leave them in the container you are using if it is large enough.

Now, you want the 'tree' to put out leaves. It may already have leaves (but we are hoping for roots first in order to feed the tree). Even now, I keep the plants away from direct sunlight.

Cut the bottom off a liter or larger plastic soda bottle or the bottom off a gallon milk jug. Place it over the plant to keep the humidity high. Keep the young plant out of direct sunlight - it can overheat. Gently acclimate (harden off) the tree to outdoors and remove the cover over time. I put them under a very shady part of the deck for a few weeks and remove the cover for a few hours and slowly move them out into the sun. Go slowly here - better to get less than optimal results than to kill the plant.

Eventually you should have a healthy baby tree throwing off roots and branches. By the 2nd summer you should be picking a fig or two (after over wintering - a whole different pain in the bottom - and transplanting into a larger container or two).

My favorite resource for figs is the figs4fun.com forum/community. Very active and very knowledgeable.

Hope this helps.

Andrew
