Favorite Fragrance in the Garden
Comments (45)I'm going out of my mind (easy for me to do) trying to figure out what this tree is that I have. I want to name it here because for about 1 month in spring it permeates the air everywhere on my property with the most magnificent fragrance. Huge tree, 1 leaf stem has multiple small leave groups with 1 leave apiece at the end, then they go to 5 leaves, then 7 leaves then connect with other same groups. Flowers are larger than lilacs but less bulky with similar fragrance - a lavendar/pinkish color. Seeds are absolutely distinctive, round hard as rock, and about the size of a dime in diameter. The seeds are grouped on the tree, but drop individually. It makes a horrible mess, and walking over the seeds is like skating on unsteady roller skates. When I first moved here I couldn't figure out where that fragrance was coming from. Took a while to figure out to look up!...See MoreWorm castings - miracle cure for diseases and pests?
Comments (32)This is a long winded thread and Im glad. I started vermicomposting last april 2013 . I didnt get enough castings to use last summer . But I did have enough to put in some cuttings I over wintered and I used nothing but castings and liquid seaweed. The cuttings are doing well and leafing more than I remembered other cuttings doing. This year I will have enough to try on my roses and honeysuckle and others. Plus I will be trying worm tea, in fact Im brewing a batch at present which Im going to test on my cuttings and seedlings. Hopefully all will go well and I can report back in detail....See MoreOrganic solutions to pests and diseases in plants
Comments (15)My getting horse manure mid-summer this year was worth it: Only 1 rose-slug out of the entire garden (50+ roses), that's on the hill where I could not apply horse manure. Previous year of NO horse manure I had at least a dozen rose slugs. High-phosphorus ATTRACT pests. Yves Seedling got DOUBLE-DOSE of Dr.Earth NPK 4-10-7 ... I was absent-minded so I applied that twice. That's the only rose which was attacked by thrips ... I killed 5 thrips on that rose, after seeing one deformed bloom. Yesterday I saw one grasshopper on that rose, so I chopped that pest into half with a scissor. I was cutting blooms for the vase, so I inspected all my roses: none of them have grasshopper, except for Yves-seedling. Yves Seedling is in its 3rd year, no thrips whatsoever in previous years .. it's a dark-red rose. Re-post the info. Here's an Abstract from Cornell University, entitled "Effects of manure and chemical fertilizers on insect pest populations on collards." http://www.researchgate.net/publication/223371840_Effects_of_manure_and_chemical_fertilizers_on_insect_pest_populations_on_collards Department of Entomology, Comstock Hall, Cornell University, Ithaca, NY " This proposition was examined using collards grown in five treatments: two with fresh manure at two levels (12 and 220 ha−1); one with ‘sheet composted’ manure at 220 ha−1; a chemical fertilizer treatment (785 kg ha−1 of 13:13:13 NPK); and a control treatment with no added nutrients. Population densities of two flea beetles and two lepidopteran pests were monitored weekly. During population peaks, flea beetle densities were significantly higher on plants receiving chemical fertilizers than on plants receiving similar amounts of macronutrients from manure. Flea beetle, imported cabbage worm and diamondback moth densities were significantly higher on untreated plants than on plants receiving any added nutrients. Flea beetle densities were also significantly higher on plants grown with ‘sheet composted’ manure than on those grown with fresh manure. " *** From StrawChicago: As to rose-midge, the only time I had that was when I did my oat-meal experiment in 2013 fall: mixing oatmeal with fluffy potting soil, and topped Golden Celebration with that in the fall. That created a perfect moist & fluffy environment for rose midge to hatch. I saw midge flying around that rose, plus deformed blooms, so I read Cornell University research which stated that too dry, or too wet would stop midge. So I put my soaking-wet-clay on top, and FLOODED that area many times per day. That took care of rose-midge for good. No other roses affected, and no midge in my 2 decades of growing roses. This year I topped my roses with DRY & alkaline RED-LAVA-ROCK and pea-gravel. Here's a good article on Rose-midge control: http://www.pghrosesociety.org/rosemidge.html "The only reported effective non-chemical control for rose midge would be daily removal of affected new growth tips and destroying the debris. This prevents of larva from dropping to the ground and pupating into new insects. Do not compost the remove plant material for this will allow the life cycle to continue in and around your garden. This requires diligent daily inspection of the new growth to detect the infestation and remove the plant part before the larva (sometimes referred to as maggots) fall to the ground. There is some anecdotal reports that removal of any mulch and loose soil around the plants in late fall will remove the embedded larva which burrows about 1-2" below the surface. Again this material must be removed from the garden or anywhere within 150 feet to prevent return of the insect. The only scientific study published in the horticultural literature on in subject of rose midge control appeared in 2006 authored by Dr. Janice Elmhirst ... The two biologicals tested are commercially available, one being AVID (with the active ingredient abamectin derived from the soil microorganism Streptomyces avermitilis and the other DOKTOR DOOM®, a ready to use permethrin formulation. The predators were a nematode (Steinernema feltiae) and a predatory mite in the form of an unidentified Hypoaspis species. The chemical control was Matador (lambdacyhalothrin), which is similar to the active ingredient in the Bayer chemical products mentioned earlier. The results of this study were interesting in that the predatory insect approach actually had a higher level of midge damage than the untreated controls. The best result came from the Doktor Doom product with less than 2% damaged rose growth. The next best was the chemical control with approximately 4% damaged tips. The Avid did better than the control but not by a significant amount." http://www.pghrosesociety.org/rosemidge.html...See Morefragrance disease resistant and compact roses for my garden.
Comments (39)rosecanadian Thank you for your excellent observation. Rose tissue analysis done by U of CA at Davis showed 2.5 to 3 part nitrogen, 2 part potassium, 1 part calcium, 1/10 phosphorus and 1/10 magnesium. Each year I grow 20+ OWN-ROOT roses in pots before transferring into my rock-hard & high magnesium clay. Clothilde Soupert balled badly in a 7-gallon air-pot, there's NOT enough calcium for its zillion petals. I transferred it into my clay (made fluffy ahead with tons of gypsum OR pelletized lime plus decomposed organic matter), and NO MORE BALLING !! I grow OWN-ROOT Firefighter 4 times since 2012 with different methods of fertilizing. The first time in 2012 was a success with frequent toppings of horse manure (rich in calcium & potassium), and the 1st bloom was 5 inch. across, see below. That Firefighter gave 40+ blooms as 1st-year own-root: My 2nd Firefighter back in 2015 was only 1 foot tall & gave 3 blooms max, fertilized with MG-soluble for roses, NOT enough calcium for form its canes & blooms. My 3rd Firefighter in 2019 was a wimp at less than 6 inch. tall, and gave only 2 blooms. I burnt it with wads of high phosphorus chicken manure, plus too much high phosphorus cow manure in the planting hole. I violated the principle of 3 part nitrogen & 2 part potassium & 1 part calcium and 1/10 phosphorus. My 4th Firefighter I learned my lesson and put 8 cups of pelletized lime in 12-gallon pot WAY AHEAD of time, and let rain-water dilute the calcium throughout the soil. I fertilize with alfalfa tea for nitrogen and sulfate of potash. Zero balling despite tons of rain plus using rain water only from my 7 rain-barrels. It gives 20+ blooms so far as gallon-size own-root received from Roses Unlimited this May 2022. Pic. taken this August, it's over 3 feet tall but slender and doesn't occupy much room....See Morestrawchicago z5
