My Knockout Rose Bushes- Did I kill my rose bushes?
Comments (2)Right, don't fertilize until they have recovered and have put out plenty of leaves. Bloom Buster is the wrong kind of fertilizer--regular Miracle Gro or Miracle Gro for Roses is fine, or any reasonably balanced fertilizer such as 10-10-10 or 18-6-12. Watering correctly is the most important thing. Keep a 2" mulch of leaves or bark around the roses. When the soil under the mulch feels dry-ish, water thoroughly with 2-3 gallons for small plants or 5 gallons for larger, plus or minus for extremely hot or very mild, cloudy weather. Usually once a week is fine. For new plants, I divide the ration in half and water twice a week....See MoreDid I kill my knockout rose bush?
Comments (4)KnockOuts and other shrub roses bloom just fine with two feedings, one early in the season as soon as you see signs of growth and again about 4 weeks later. The timing of any fall feeding depends on your zone. KnockOuts are typically on their own roots (not grafted to another rootstock). Since it gets so hot here (8a) so quickly, I usually use liquid fertilizer on my own-root roses the first year. I like organics (fish fertilizer, alfalfa tea etc) but have also used Mills Liquid feed. As a rule, don't feed a stressed plant. Make sure it gets adequate water; water more frequently when weather is dry and windy. Mulch it well to keep the roots cool. I give all my roses a cold water shower during hot dry periods....See MoreHelp with my knockout roses!
Comments (9)The first thing I would do is pull the mulch back from the base of your roses. It may not be a problem yet but it does cause rose cane problems. Then hurry and water that rose if you have not already done so. There is of course the possibility that the water is not draining well in that spot. That is something you can check by digging down a bit. Either problem can cause the leaves to brown so it is important to check. Be sure to check the other rose as well to see how its soil is to give you an idea of why it is happy. Then with a gloved hand check to see how solid the rose is sitting in the ground compared to the other rose. The canes are still green so she will leaf back out once the problems are solved. Sometimes it is as simple as air pockets. For this you can step on the soil around the rose a bit to firm it up. I'll stop here as to me any way it looks like a soil water issue. I would also give the rose some shade while it recovers. Leave the leaves on for now so they can also help shade the canes. Try to remember to pull the mulch back from the canes. Good luck with your rose baby....See MoreWill my knockout rose plant that i bought last year revive?
Comments (11)That's the attitude. It's hard, but not impossible to overwinter them. Was this unheated garage attached to your house? If not, it's unlikely to ever work in your zone. As suggested, raise them off the floor and use a bigger pot which will give the roots more insulation as well. You could also wrap the pot in bubble wrap or something insulative. That, plus water will give them a fighting chance. I've done this for a few years now, but will admit to some losses this year, but only because I didn't realize outside air was entering the space due to some structural changes. I'll be fixing that. Any chance you can put a rose in the ground?...See Moreyork_rose
