For the floor inside the box, we wanted to have good drainage. We could have made the floor out of wooden slats or wire mesh, but we chose instead to use two old stainless steel refrigerator racks. These are perfect because the nursery flats can drain easily, and air circulation can come up through the racks. And, the metal racks should last longer than wooden slats, which would have a tendency to rot.
The first year we used polyethylene plastic film for the walls of the misting box. This proved to be a bad choice because the film did not hold up and within one year had to be replaced with rigid corrugated siding -- a much better choice.
Materials We Used Schedule 40 irrigation pipe, the length will depend on how far you locate your box from your water source. Misting Head Saddle to attach mister to pipe Timer or Mist-A-Matic Unit Wood for the frame and legs: Four 2" x 4" x 5' (legs) Four 2" x 4" x 20" (sides) Four 2" x 4" x 36" (front/back) Wood for the doors: Two 25" x 19-1/2" pieces of 3/4-inch plywood Latch and hook for the door Clear corrugated plastic: Two 26" x 13" (sides) One 26" x 39" (back) One 33" x 23" (top) Scalloped wood braces for attaching the corrugated walls: Four 12" pieces for the side walls Two 26" pieces for the back wall 32 screws for the scalloped wood Nails Two 18" x 18" plastic nursery flats Hinges for the doors Screws for the hinges Old refrigerator racks, or wooden slats, or wire mesh for the floor
Tools Needed Hammer Drill Screw Driver Saw Tape Measure
Building the Box 1) Start building the frame by nailing the four 5-foot legs onto the four 2" x 4" x 20" side braces, placing two braces at the top, and two positioned at about 32" from the ground.
2) Next, securely attach the legs and side braces onto the 36" front and back cross braces.
3) Attach the clear corrugated walls to the sides, top, and back, leaving the front open until you build the door. We used scalloped wood braces, which fit over the corrugated walls to hold it into place with screws.
4) Now attach the two doors with the hinges and screws.
5) Place the wire refrigerator racks onto the floor of the box (or you will need to attach a slatted wood floor or wire mesh if you don't have wire racks).
6) Place the plastic nursery flats on top of the flooring.
7) Now bring the misting box to its location and prepare to install the plumbing, misting head, and timer.
Plumbing/Irrigation You will need to run some Schedule 40 PVC irrigation pipe from your water source to your misting box. So the length needed will depend on how far your misting box is located from the water source. The pipe will then run up to the top and then inside of the misting box. You will have to cut a hole into the side of the box into which the PVC pipe will be placed. Then drill a hole into the center of the pipe, where you will install the misting head.
Misting Head At first we tried those little misting heads that you use on your patio to keep it cool. These plugged up often and proved to be too much trouble as we were often cleaning them out -- a waste of time and money. We eventually changed over to a Dramm Misty-Mist #34-MI/36 PSI. They were purchased from the Geiger Company for 73 cents each and only rarely need to be cleaned out (maybe twice a year). We used only one misting head for our small box because each head covers a 3-foot area. Geiger has a free 300-page catalog which includes all kinds of nursery supplies; contact them at 800-443-4437.
The Timer When we first set up our mister, we looked through catalogs and took many trips to various hardware stores to see what kinds of timers were available. At first we installed a pair of battery-powered timers, as each one only had four times per day that they could turn on, and we wanted the mister to come on once every hour from 9 A.M. to 4 P.M. Each timer runs on two 9-volt batteries, which need to be replaced twice a year. Another model we tried could not handle our very high water pressure of 120 psi and kept exploding. Other models we experimented with were just not dependable in coming on every hour, and the batteries often failed. These battery-powered timers cost about $45 each.
Eventually we switched over to the Mist-A-Matic system, and we like it a lot. It automatically turns on by sensing the moisture level. It is more expensive and has to be hard wired. But it will be well worth the money as we will not have to buy a timer and replace batteries nor bother with resetting the times throughout the year. We got ours as a hand-me-down from an elderly rosarian friend who retired to a nursing home. But, you can buy a new one from E.C. Geiger for about $198. Geiger's web page can be viewed at http://webserver.hortnet.com/ecgeiger/mist-a-matic.html. Another supplier is Morton Horticultural products in Tennessee, who sells the Mist-A-Matic for $175. A one-inch solenoid valve will cost an additional $20. Their web page is mortonproducts.com, e-mail mortonprod@blomand.net, telephone 1-800-473-7753. The Mist-A-Matic is shown at http://mortonproducts.com/page.cfm/5207. You can locate other suppliers of the Mist-A-Matic on the Internet just by typing in Mist-A-Matic in your favorite search engine, such as google.com or yahoo.com.
Here's how the Mist-A-Matic works: A special stainless steel screen on the handle of the unit raises up when it is dry. When this happens, it throws the mercury switch, which opens the solenoid valve and starts the misting cycle. When this stainless steel screen accumulates enough mist, the weight of the water drops it down again, shutting off the mercury switch, closing the solenoid valve. It needs practically no care or maintenance and can be left on, unattended day and night. This control unit is a very practical instrument, which will have a long lifetime of carefree maintenance. There are no clocks to adjust, and it is not affected by water conditions. It works simply on the weight of water. The major benefit of the Mist-A-Matic is to control the misting cycle according to weather conditions. Too much water promotes disease and wastes water. Too little water causes leaves to wilt and failure to root. The Mist-A-Matic distributes the correct amount of water. In hot weather, the unit will turn on more frequently as the water evaporates. In cooler weather, the unit turns on less frequently. For operation, you will need to plug the unit into an electrical outlet. You need to hook it up to a water source and a misting head.
How to Take Cuttings So now that our mister is finished, let's take some cuttings. Take a 6-inch cutting from any type of rose (except a patented variety). Remove all sets of leaves except the top two. Fill a 2-inch pot with potting soil. Poke a hole with a pencil, halfway down in the pot. Dip the end of the cutting in a rooting hormone such as Hormex, RooTone, or Dip 'n Grow. I like Hormex the best! Insert the cutting in the soil and tamp the soil tightly around it. Water it well, but do not fertilize it. Place the cutting in the mister, and it should begin to take root within 6 to 8 weeks.
Planting Mediums The planting medium that I have found to be the most successful for rooting rose cuttings is a 50-50% blend of sterile potting soil and perlite. This is a very light blend that encourages the roots to grow.
Whatever planting medium you decide to use, the soil needs to stay moist and yet have good drainage.
Other Tips for Rooting Cuttings: o Use sharp cutters to prevent crushing the stem. o Rooting hormone is optional; it works with or without it. o Label your rose cuttings with their proper name. o It takes 6 to 8 weeks for the cutting to root, depending on the weather. o Keep the cuttings moist at all times, with good air circulation, drainage, and sunlight. o You can make slits in the bottom inch of the stem to encourage more rooting, but I have found that it works much better with the slits. o Make sure that the pots you use are very clean. If they are being reused, they must first be washed out with soap and water. An automatice dishwasher works well for this task.
When to Take Cuttings The best time of the year to take cuttings in Southern California is April, May, June, or September, October, and November. July and August are usually too hot as the temperature sometimes soars to over 100 degrees, but I have done it and the success rate is much lower then. I have also taken cuttings in December when our nighttime temperatures sometimes reach freezing, but again, the success rate is lower because it is too cold, and the cuttings take much longer to "strike." This timing should work well for most southern states, but in the colder northern states, spring and summer will be the best times to take cuttings.
Winter & Summer Protection If you're going to take cuttings in summer or winter you will need to take some extra precautions. In winter, we cover the top and sides of the misting box with heavy blankets at night to prevent the cuttings from freezing. In the summer (July, August, and sometimes into September) we cover our misting box with green meshed shade cloth to keep the cuttings cooler. It will depend on your local weather conditions.
Getting the Most Out of the Misting Box I use my misting box year-round, so it is always set up and ready to go. It really comes in handy for those times when I come across some rare and unusual roses. When I visit my friends' homes, or go on garden tours, I'm not shy about asking for a cutting of some rare old garden rose, or other unusual, hard-to-find varieties. They know that I will happily reciprocate by giving them cuttings from my garden. When we go on fishing trips, I've been known to bring home cuttings of wild roses such as rosa woodsii, which I have found along the riverbanks. And, since I help to produce two roses shows each year, I always make a beeline to the old garden rose table to grab the stems before they are thrown out at the end of the show. With my misting box I've had the pleasure of growing various types of unusual roses, and I also put many on the raffle tables of my local rose societies for others to enjoy.
