Cover the cutting loosely, pot and all, with a plastic bag or plastic wrap and keep the soil moist. Putting a tall stake into the pot will hold the plastic away from the leaves. If the plastic touches the leaves, they remain wet and can succumb to a fungus disease. Along the same lines, make sure the condensation can escape from the plastic or the stem will rot.
as mentioned when I replied to Mick, the powder with be a fungicide as we’re trying to help prevent dampening off – although careful watering is always the best solution to this problem. The hydrogen peroxide mentioned in the blog will be the same as the hair bleach and is just an extra precaution taken by the author to sterilise her seeds. Using normal bleach in tiny quantities is usual practice in preventing harmful bacteria in seed processes, especially if they are prone to disease in the first place.
While your cuttings take root, keep them covered and moist. In a garden bed, a simple DIY mini greenhouse does the trick. Just place a bell jar, a garden cloche or an overturned mason jar over the cutting. A clear plastic bottle with the bottom cut out and the cap removed works, too. Water the soil regularly to keep it moist, but not soggy. Your mini hothouse will keep the humidity high inside.
The Baggie Method: This was the first method I ever tried. Here you fill 2-inch plastic pots with potting soil, insert the rose stem halfway inside the pot, then put the pots into a one-gallon plastic zip-lock bag. You can get four 2-inch pots into each gallon bag. I didn't like this method because it caused many of the cuttings to rot since the bags tended to fold over and therefore prevented the air from circulating. The success rate of this method is not very good. It may be helpful to place a couple of small sticks inside the bag to help keep it upright and full of air.
Allow rose hips to develop by leaving dead flowers on the plant. The flowers are typically pollinated by insects, or pollinate themselves in some varieties, so there is no need to pollinate by hand unless you are breeding specific plants together. Leave the flowers on the rose plant without cutting them. After they wither, small fruits known as rose hips will develop in their place.
Plant the rose bush seeds approximately ¼ inch deep in a seed-planting mix in seedling trays or your own planting trays. The trays need not be more than 3 to 4 inches deep for this use. When planting rose seeds from various rose bush hips, I use a separate tray for each different group of seeds and label the trays with that rose bushes name and planting date.
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 with misting nozzles.
Roses are usually grouped into one of two broad categories: old roses and modern roses. Old roses are those varieties discovered or developed prior to the introduction of the hybrid tea rose in 1867. But like everything else in the world of roses, when it comes to determining how a particular rose should be classified, it’s not always crystal clear.
I bought hybrid tea roses last year. Not long after the first blooms, we moved one because it was interfering with the sprinkler system. It looked unhappy at first, but continued to bloom throughout the season. This year, it does not have so much as one leaf, no new foliage whatsoever, however, there is still green inside the stem towards the base of the cane. Is it done for, or is there a chance it will come back in it's second rear?
