Comments (45)Absolute zero for foliage is different for different varieties. Anywhere from 32 to 15 degrees.Consider absolute zero for foliage to be when the leaves freeze to death. Absolute zero or 55.4F pertains to citrus roots. At 55.4F citrus roots cease to function. You are correct WLD is not a serious problem for trees grown outside. However for trees grown indoors in an artificial situation WLD can be a problem as many, many hobbiest can attest. You seem to generally have a good understanding of the problem. When a citrus tree is placed in a cool room and the foliage is directly in front of a southern exposure a problem can occur. Direct sunlight can easily raise the leaf surface 18+ degrees above the ambient air temperature, depending on the duration of time the tree is subjected to these conditions. If the tree's roots are at 55.4F degrees or lower the citrus roots cannot and do not function. They cannot sent the required water up to the foliage for evaporation to cool the leaves. Even at temperatures closely above 55.4F the root's ability is many times insufficient to properly cool the tree. Many times WLD happens after a very sunny day. WLD rarely happens after cloudy days. Stressbaby, your correct in your thinking. The value of the lights for a tree in the situation that I described above is to keep the growing medium's temperature high enough so that the roots can operate. If your greenhouse conditions are such that the temperatures can keep the roots approximately at 64 degrees then you should not need the extra protection that lights can afford. Unless you are only trying to obtain the maxium growth out of your trees all year around. An example an orange tree in Florida might take 10 years from seed to produce fruit, but the same tree in the tropics might only take half the time. BTW nice home and greenhouse. Your an interesting person, I'm glad you joined the citrus forum. Take care. - Millet...See MoreHanging xmas lights on a 25' spruce tree
Comments (4)I realize I'm a bit late here, but I still haven't hung lights on my 25' spruce. I use a long bamboo pole attached to an old broom handle. On the end I made a fork out of two pieces of bamboo that is wide enough to catch the wire easily but narrow enough that the lights don't slip through. If you email me I'll gladly send you my address so you can send your monetary thanks for keeping your limbs unbroke and your holiday trappings frustration to a minimum. I'm quite certain the plan will work so well that generations from now your offspring, with their 100 foot light-hanging poles will still be sending my offspring money and gifts in gratitude. And since I accept responsibility for both the good and the bad, metal mop handles should not be substituted for old wooden broom handles (ya gotta have the lights on to see how your'e doing) and goggles should be worn when installing and viewing the light display....See MoreHow to safely hang x-mas lights on a tall outdoor tree
Comments (6)I did a search on the net and this is the only store that I could find that sells something for hanging lights in a high tree. You can order it online or go to one of the two stores in VA if you live near there. I'd be surprised if one the home improvement stores you mentioned wouldn't sell something for this or give you a suggestion on where else to look. You could always print from this site and take it to the store when you ask them. http://www.merrifieldgardencenter.com/products.php?pid=99014422&openparent=1523 Here is a link that might be useful: Decorating Pole for hanging lights in trees...See MoreDoes your x-mas tree have a theme?
Comments (16)Should it? Well, I've been working with a interiorscape company for businesses decorating themed trees for the last month - they look fabulous to the point where I'm now thinking of redoing mine. I'm tired of my mish mash but there are those ornaments that just mean way to much to exclude. Things learned while working: Prelit trees - by year 5 the lights get blown, and you have to get concerned at this point of overheating the tree. Yes you could replace the bulbs if you can find the right ones. Too bad I know this now - got one of these babies last year and found it too bright - the space shuttle can be guided in for a landing with this tree! The company has rescued some of the client trees with wire cutters to take out the lights but given the time required and manhours, it's cheaper to buy a new tree. BTW, the charity shops right now are putting out their xmas stuff and you can get good trees really cheap, along with wreaths. Got one for $1.99. It was all flat with dead decorations - remove all that stuff, refluff it and dust it off with a soft brush and you can redo it yourself. The dollar stores have terrific ornaments at a good price. Also, the first weekend in Dec the ornaments start getting reduced dramatically if you're looking for bargains....See More- last year
