Addilyn Daniel's Answer · I've seen this problem on roses, azaleas and other types of plants. Aphids could be the problem. When the new growth was emerging in spring did you notice if there were small bugs all over the foliage? Often green but occasionally light-brown, and sometimes with wings, aphids may cover the complete growing tips of the rose. Aphids are most active in spring and summer and multiply at a prodigious rate feeding on the sap of the plant. In large quantities they may seriously retard the growth of the plant and ruin buds. They are particularly damaging to the new shoots with subsequent damage to the emerging leaves which become malformed.)
