My old rose bush
Comments (21)I second Kim Rupert's wisdom. He bred many hardy roses (down to zone 2), plus thornless roses. Check them out! I first bought a soil-test kit from HomeDepo - it showed neutral pH of 7. Then I bought a second one from Lowe's, the instruction asked for 1 teaspoon of soil! I'm laughing here since you can't tell much from that little soil. EarthCo. tested my soil pH to be 7.7 After much searching I found that the over $200 pH meter needs to be re calibrated before using. That's too technical for me, so I tried the red cabbage juice as pH indicator. A chemist in the Soil Forum thinks it's a good idea too. The fish-tank litmus paper sold at Walmart for $5 is accurate in the alkaline range, but not in the acidic range. It is used to test your water, and not your soil. With the red cabbage juice you can collect as many samples as you want, like from 10 different places in your garden. Place 1 heaping tablespoon of soil from different places in those plastic fruit cups - then you can compare the pH difference in different spots of your garden. Chop 50 cents of red cabbage, boil in DISTILLED WATER ($1 a gallon) for 10 minutes, discard the solids. Distribute the warm red juice equally in tiny fruit cups and test these separately: one drop of vinegar (pH 2 to 3) for the 1st cup, then 1 teaspoon of baking soda (pH of 9) for the second cup, MiracleGro potting soil (pH of 6.5), this should turn light pink. One heaping tablespoon of soil from different places placed in separate cups. If your soil is neutral, the juice will turn slightly blue, but still mostly purple. If soil is alkaline, the juice turns bluish green, like the baking soda at pH of 9. If the soil is slightly acidic, then it's the same color as MiracleGro. The range is more pink for more acidic, then neutral purple (color of cabbage juice), then blue (slightly alkaline), then bluish-green, and bright green is over pH of 10. Since red cabbage juice has a wider variation in colors, it is more accurate than lichen, used in litmus paper. I never try corn meal as fertilizer, although corn meal gluten is 10% nitrogen by weight. I found this interesting link on corn meal as a pre-emergence herbicide. My brother in Grand Rapids, MI has to apply lime to his acidic soil. Gypsum is the only one that is safe for BOTH alkaline and acidic soil. Alfalfa meal, in rabbit pellets, is acidic, pH of 5 to 6, peatmoss is acidic at 4 pH. It's best to test for your soil's pH before applying rabbit pellets. EarthCo, or drgoodearth.com tests your soil pH, organic matter, phosphorus, potassium, magnesium, and calcium for $20. For trace minerals you pay $10 more, or $30 altogether. You send in 1 cup of soil from your garden (postage paid by them). They give you a booklet of soil chemistry, it's worth it.

Comments (5)I suspect the rose bush it was purchased for has died and what is growing now is the root stock it was grafted onto. This root stock is a once a year blooming rose that only blooms on second year wood. The flower buds on these types of roses are formed the previous fall The fact that you cut it back means you cut off any canes that would have produced blooms this year. In zone 5 we often experience a lot of winter dieback that kills any canes that might have produced flowers. It could also be an old garden rose which also only blooms on year old wood. Either way by cutting it back you've removed any flower buds. My advice would be to remove the bush and replace it with a repeat blooming hardy shrub rose or one that you don't mind having to provide some winter protection. These bloom on new wood and even if they dieback or are cut back, they'll bloom....See MoreCan I relocate my antique rose bush now?
Comments (8)Now is not a good time to move a rose on Cape Cod. It is in the midst of its growing season and will be putting its energy into top growth not establishing roots. Are you certain that the problem is not enough sun? Right now roses on the Cape have been devastated by the winter moth and the other caterpillar that is devouring the new growth. I would guess that the rose is being badly damaged by these pests. Check the rose carefully and remove and destroy any caterpillars on the rose. Check every day for new ones and remove them. Give the rose lots of water; we have not had any rain in over a week and I noticed that all my roses are needing a good drink as I have been away for a week. Go to Country Garden or what ever garden center is close to you and buy fish emulsion with seaweed. Follow the directions on the label for feeding and give the rose a feeding every other week. Make sure you give it plenty of water. I have all my roses in pots in the shade because they don't dry out as fast and they are doing fine. I would wait to transplant the rose until the fall after it goes dormant or next April before it breaks dormancy. Make sure you dig a BIG hole and add an entire bag of composted cow manure or whatever you can get at the garden center to the hole along with a couple of cups of Rose Tone. Mix it well with the sandy soil in the hole and plant the rose.

Comments (22)You don't want to spray Roundup or any similar herbicides near your roses. The spray can drift far (20 - 30 feet), and the damage looks similar to your third photo. Not saying that it definitely IS herbicide damage, but I wouldn't do any more herbicide sprays around the roses. On the chili thrip front, in addition to the state ag folks, send a copy of the photos to Dr. Malcolm Manners at Florida Southern College (Google him). He stops by the forums from time to time (usually over in the Antique Roses forum), but a direct email would be best....See Morejardineratx
