The Rhododendron on the property I took over last year is struggling and has very few leaves this year. Also, avoid fertilizers with too much nitrogen since it promotes lots of leaf growth without blooms. In this case, you can wipe the mold off, but will need to get rid of the insects to prevent it from coming back. 0000009258 00000 n @G,R�����Pĕ`��i� �� �EOO���1�[ w�0�G�fbo� �.%� endstream endobj 60 0 obj 188 endobj 26 0 obj << /Type /Page /Parent 21 0 R /Resources 27 0 R /Contents [ 35 0 R 37 0 R 41 0 R 43 0 R 45 0 R 47 0 R 49 0 R 51 0 R ] /MediaBox [ 0 0 612 792 ] /CropBox [ 0 0 612 792 ] /Rotate 0 >> endobj 27 0 obj << /ProcSet [ /PDF /Text /ImageC /ImageI ] /Font << /TT2 28 0 R /TT4 29 0 R /TT6 39 0 R >> /XObject << /Im1 58 0 R >> /ExtGState << /GS1 55 0 R >> /ColorSpace << /Cs6 30 0 R /Cs8 31 0 R >> >> endobj 28 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 169 /Widths [ 254 0 0 0 0 0 0 0 0 0 0 0 328 379 328 0 701 490 626 625 0 599 648 554 676 648 367 0 0 0 0 0 0 758 757 715 0 0 671 0 0 0 0 0 0 1023 0 820 701 0 797 649 684 833 0 1126 0 0 0 0 0 0 0 0 0 596 646 0 663 572 0 577 680 354 0 0 344 1016 690 636 658 0 520 513 397 677 567 863 588 562 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 519 519 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 942 ] /Encoding /WinAnsiEncoding /BaseFont /IMLJEO+Georgia-Bold /FontDescriptor 33 0 R >> endobj 29 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 122 /Widths [ 352 0 459 0 0 1076 0 269 0 0 0 0 364 454 364 454 636 0 0 0 0 636 0 0 0 0 0 0 0 0 0 0 0 684 686 698 771 632 0 775 0 421 455 0 557 843 748 787 603 787 695 684 616 0 0 989 0 615 0 0 0 0 0 0 0 601 623 521 623 596 352 623 633 274 344 592 274 973 633 607 623 623 427 521 394 633 592 818 592 592 525 ] /Encoding /WinAnsiEncoding /BaseFont /IMLJHP+Verdana /FontDescriptor 32 0 R >> endobj 30 0 obj [ /ICCBased 57 0 R ] endobj 31 0 obj [ /Indexed 30 0 R 255 56 0 R ] endobj 32 0 obj << /Type /FontDescriptor /Ascent 1005 /CapHeight 734 /Descent -209 /Flags 32 /FontBBox [ -50 -207 1447 1000 ] /FontName /IMLJHP+Verdana /ItalicAngle 0 /StemV 96 /XHeight 546 /FontFile2 53 0 R >> endobj 33 0 obj << /Type /FontDescriptor /Ascent 916 /CapHeight 687 /Descent -219 /Flags 34 /FontBBox [ -190 -217 1295 912 ] /FontName /IMLJEO+Georgia-Bold /ItalicAngle 0 /StemV 133 /XHeight 484 /FontFile2 52 0 R >> endobj 34 0 obj 802 endobj 35 0 obj << /Filter /FlateDecode /Length 34 0 R >> stream 0000003485 00000 n All rights reserved (About Us).

Wash the leaves with insecticidal soap to get rid of the insects and the black stuff should go away. 0000060582 00000 n I'd wait until after this year's bloom to do the deed. So hopefully that helps. Hi Darlene…If you can scrape the black off, that is usually sooty mold which grows on the honeydew left behind by certain insects like aphids, whiteflies and scale.

It looks like it’s dying but it didn’t happen till after blossoming. Look for ones that specifically say Rhododendron fertilizer (or food) on the packaging. Reading your post I think that it can be the lack of water and the shade that is present almost all morning on our balcony.
