Re: Healthy Roses

Yellow leaves with green veins typically indicates an iron deficiency. Other
trace elements may also be lacking, but any good trace-element fertilizer
should cover those as well. Even if these minerals are present in your soil
severe pH imbalance in either direction can render them unavailable to your
plants. Since your soil is alkaline, use Miracid, both as a drench and
foliar spray. You should see results within 3 days. Re-apply every 2-3 weeks
during active growth.
