Looking for a light yellow rhododendron
Comments (3)rhodyman, ggardens is in PNW, cool summers and wet mild winters - not much in the way of heat to contend with other than some better temps in Aug and Sept when its typically dry - but I think you know that already :). Ggardens, if I were you in your location, I'd make a stop at Valley Nursery or Bainbridge Gardens and see what they have to offer in the way of yellows. You'll find experienced staff to advise and guide you towards disease and insect resistance at either, and either would be a fun place to spend an afternoon - I try to make a day trip doing that later in Spring each year....See MoreHelp! Stems of rhododendrons turning yellow
Comments (2)Rhododendrons and azaleas require only a smidgen of the trace element aluminum. Feeding it aluminum sulfate on a long term basis can be bad for them. Instead of that chemical, try using either ammonium sulphate, ground sulphur or ferrous sulfate (iron sulfate). I only use aluminum sulfate to acidify hydrangeas' soil and turn the blooms blue. The ARS suggests using 1.5 pounds of ground sulfur per 100 square feet mixed into "average" soil in order to lower the pH by 1/2 point. However, if your soil is sandy, use 0.5 pounds of ground sulphur instead; if your soil is clay then use more: 2.5 pounds. For specifics on these topics, you can also read the article on the link below. Luis Here is a link that might be useful: Am.

Comments (5)Hi Harborrose: My rhododendrons are 9 years old. They are right in front of my door - look the same every year until now, the leaves have pink streaks when I put espresso grounds (we have lots of rain). I don't know what's in the espresso that put pink stripes to the leaves - I tasted the espresso, extremely bitter compared to my hubby's ground. For the past month all my roses are great - dark green leaves with hubby's coffee ground from Sam's club. Hi Michael: Thank you very much for your info. I tested the acidity of both espresso and coffee ground twice: with red cabbage boiled in alkaline hard water, the second time with red cabbage boiled in distilled water. What happened puzzled me until you clarified - many thanks: Red cabbage indicator boiled in alkaline tap water: espresso ground and coffee ground both turned pinkish (acidic) within 10 minutes. After 4 hours the reddish water changed to CLEAR in the coffee ground solution (you are right about its instability, I also read that coffee ground is a buffer, rather than acidic). The solution above the espresso ground retained its pink color. I repeated the experiment again today, with red cabbage boiled in distilled water. Both coffee ground and espresso turned reddish brown. After 1 hour, I was surprised to see a CLEAR SOLUTION above the coffee ground -the espresso ground solution was still pink. I also tested red cabbage boiled in distilled water with at least 10 other samples. Here are the results: Purple indicator turns BRIGHT pink with a few drops of vinegar (reported pH 2.4) - Espresso ground is next in pink (my estimate pH 3 to 4) - Coffee ground is slight pink but turned CLEAR after 1 hour. The control red cabbage color is the SAME as indicator solution in Epsom salt (pH is neutral as expected). Previous wrong alkaline result with Epsom salt was from boiling red cabbage in hard alkaline water. There is no change in color with calcium citrate (it's just more whitish with calcium dust). Baking soda is bluish-green (reported pH of 9). Magnesium supplement (magnesium oxide) is bright green, and the most alkaline. Peatmoss is the same color as alfalfa meal within the first 5 minutes - but after 1 hour settling down the peatmoss is clearly darker pink. Reported pH of peatmoss is 4, my estimate of alfalfa is 5. MiracleGro potting soil is slightly pink (reported pH of 6.5). My amended topsoil is slightly bluish-purple (reported pH of 7.7, tested professionally by EarthCo.) - The bottom yellow clay is more blue, my estimate pH of 8, same as tap water tested with fish-tank litmus paper. Here's my big disappointment with HomeDepo's EarthGro bagged topsoil (the white/red bag). It's greenish blue, at least 8.5 pH. Horse manure is alkaline as expected, my estimate at 8.7 (others report a higher value). The Moo Manure (sold at HomeDepo) is the most alkaline, the same color as the baking soda solution (reported pH of 9). The most prolific bloomer in my garden is Radio Times, planted in Scott's Premium topsoil with peatmoss - I did not test this, but expect it to be neutral, or slightly acidic with peatmoss. Other roses amended with HomeDepo's Earthgro topsoil or Moo-manure don't bloom as much, with more yellowish leaves. Now I know why....See MoreBeware (rant), this is why good sellers HATE ebay!
Comments (19)I ordered from iyares before. I also got nothing! Ebay refunded me because they entered no tracking. Then they asked me why i filed....i didn't leave them negative because i gave them the benefit of the doubt....the person that gave me negative only did it because they didnt get their way. They said that the cactus separated in 3 places. I actually stated in my auction that it may not stay intact because it was a 9 tail large monkey tail cactus. She wanted a discount outside of ebay and without showing proof of any damage. i said i couldn't do that but that she was welcomed to return it for full refund. I never heard from her again until her negative fb. She lied! I package very carefully. I cant help how the mail handlers treat packages... I could easily reroot every bit of that monkey tail and so could she. She wanted it but wanted it for nothing...i will not give into con artists ever!...Ebay is so unfair to sellers. The bad buyers have totally taken advantage of this...I've even sold to tricky garden webbers that are amungst us. They brake leaves in the weirdest places and ask for me to send another plant...pfft, yeah right! I dont think so! These people are ruining ebay!...See Moremainegrower
