Q. Height of Parade Rose

What height do the miniature Parade roses grow? Does each one need its own 10- to 12-inch round planter, or can two or three miniature roses be planted in the same container? They will be growing outside.

The height of the Parade mini roses can vary from plant to plant; however, I believe most of them get to be 15 to 16 inches tall. You could put two in a pot and they would fill out nicely, making for a wonderful display. I am providing a link to Poulsens website as they are the hybridizers for the Parade line of miniature roses. If you know the name of your Parade roses, such as Apollo or Fiesta, you can click on the name for more information about your particular little rosebush. I do believe most of them do get bushy, so they should fill in a 10 to 12 inch pot nicely. Just remember that you do not want them to fill in too tightly, as that limits the airflow through the bush and creates a fungus breeding ground for black spot and others. http://www.poulsenroser.com/

Q. Rose Blooms Do Not Last?

Our rose blooms do not last, we get plenty of blooms but after a day or so the petals start dropping off. Water every 2-3 days, feed every 7-10 days. What might the problem be?

I am not sure where you are but if you are in an area where the temperature is very hot right now, that can cause the blooms to open quickly and then fall apart. Many yellow blooming roses have this problem. I have had some that are in a nice opening bud stage when I leave for work and then are totally done when I get home from work on hot summer days. The feeding at 7 to 10 days is a bit heavy unless it is all foliar feedings. Even then it can be a bit much causing heavier foliage growth and less blooming with weak blooms when you do get them. I would cut back on the feeding and use a moisture meter to check the soils moisture around your roses. They may need more water than they are getting if it is hot where you are. They may also be getting too much water if it is not hot where you are. Too much water can make the soils heavy and thus lock out the oxygen that does actually move into and through the soils, this will cause lack lustre performance as well.

Q. Dog Tearing Up Plants

I am looking for some plants that my dog will not rip, tear, chew or pull out of our yard. So far she has pulled out most of our plants and pulled out three rose bushes. I was also told about using Liquid Fence repellent. There has to be some plants dogs will not chew. We live in the state of Washington.

Q. Tips of Stems

The tips of the stems of my rose bush have turned black, no spotting on the leaves. It’s just on the stem. What do I need to do?

It sounds like you have a little bit of what is called Rose Canker or die back. Sometimes it gets into the canes when pruning the roses or deadheading them if the pruners are a bit dirty. I would recommend wiping down your pruners with some Clorox or Lysol disinfectant wipes, then prune out the blackend ends and seal them with Elmers or some good white glue, but not school glue. This article should also help: https://www.gardeningknowhow.com/ornamental/flowers/roses/pruning-roses.htm

This blackening can also happen if pruners are a bit dull and squeeze the cane or stem a lot before actually cutting it.

Q. Powdery Mildew on Roses

I have a limited budget. I would like a recipe to make spray that removes powdery mildew. I heard that you can use Murphy’s Oil Soap and baking soda. Not sure the ratio of the ingredients, so if you could help me, I would be grateful.

There is a product called Green Cure, and here is a link to their website to learn more about it: http://www.greencure.net/.

If this is still too costly, then here is a recipe you can try: 3 tablespoons baking soda plus 1 tablespoon of Murphy's oil soap or a lightweight horticultural oil in 1 gallon of warm water. Mix well and let cool. Mix or shake up well again just prior to spraying. Apply this spray every 7 to 10 days until the powdery mildew is gone. Be sure to spray under the leaves as well.

Q. Small Insect Infestation

I have found on my roses and columbine large numbers of a small black insect, at most 1/8 inch long and very thin. I had never seen them before; they do not look exactly like thrips. For all I killed with a spray, more appeared and did damage, also on new citrus leaves and flew in swarms. There was also balling of some of my rose buds.

It sounds like thrips to me. They can be extremely tough to get under control and many times the use of a systemic insecticide is needed. There are also some sticky yellow pads that you can buy to catch many of the adult thrips so that they cannot make more thrips. They are attracted to yellow. Here is an article that will help as well: https://www.gardeningknowhow.com/plant-problems/pests/insects/controlling-thrips.htm

Q. Rose Plant Mushrooms and Mold

I noticed this morning that my potted rose plant had a mushroom growing out of it and mold on the topsoil. I took off the mushroom, but I’m not sure what to do now. Can you give me any advice?

Sometimes the outdoor use potting soils will be less sanitized than some of the other indoor or even indoor & outdoor use potting soils. Remove two to three inches of the potting soil from the pot (depending on the size of the pot), being careful not to disturb the feeder roots. Then replace the removed container soils with some indoor or duel use indoor/outdoor potting soil. That will usually stop the mold and mushroom problems.

One other thing to note though. If your potted rose does not have a drainage hole in the bottom of the pot, the soils are possibly staying too wet due to no drainage, which leads to mold once the soils are saturated and have set for a while. This same thing can happen if the pot is in a tray or saucer at the bottom to catch the water that runs through the soils in the pot and that tray is not drained after 30 to 45 minutes. Saturation of the soils will eventually kill the rosebush as well.
