I am particularly interested in finding the soil PH levels for flowering plants such as the Korean lilac, Burning Bush and roses. Thank you
Thank you. I'm mainly interested in the ph requirement for lilacs and more importantly the Korean Lilac.
Lilacs generally do best with fairly high pH (7-8). What do you mean by 'Burning Bush'? That can mean several different plants (or a political statement!)
Sorry I don't know the technical name. The bush I have has dark green leaves during the summer which turn bright red in the fall. Thank you for the information on the lilac's ph. My soil is about where you said it should be. Some of the leaves have dark spots and are curling up and turning a grayish brown. It can't be lack of water since we have had above normal rainfall this summer. I just planted 3 of these lilacs this year and I hope I'm not going to lose them.
Hi Navaf, I think your burning bush is Euonymus alata aka Euonymus alatus aka winged Euonymus. http://home.howstuffworks.com/define-burning-bush.htm http://www.hcs.ohio-state.edu/hcs/TMI/Plantlist/eu_alata.html http://tncweeds.ucdavis.edu/alert/alrteuon.html http://www.invasive.org/eastern/srs/WBB.html They like good drainage so I suspect you have some type of leaf spot from the rain. Clean up all fallen leaves as often as you can and don't leave any on the ground over the winter. Provide good drainage. Here's a picture of the coral spot nectria canker on the bark mentioned in the second link above. http://johab.nong21.co.kr/bh/pic/cd06_bb.jpg Winged Euonymus scale can also be a pest, but the leaves tend to turn yellow. Take a look at pg. 10 here. http://www.mortonarboretumphc.org/PHC report pdfs/050605 Issue 3.pdf#search="Winged Euonymus scale" It can tolerate a wide range of pH. http://64.233.161.104/search?q=cach...+Euonymus+alata+++pH&hl=en&gl=us&ct=clnk&cd=3 You might find this helpful in determining the pH levels plants prefer. http://www.extension.umn.edu/distribution/horticulture/components/1731-29.html http://msucares.com/pubs/infosheets/is0372.pdf http://www.humeseeds.com/soilph.htm http://www.gardenguides.com/TipsandTechniques/ph.htm http://www.ranchomondo.com/compost/phfactor.htm Newt
