Despite our best efforts to manage our soil
correctly and add the nutrients we need, we may still notice some nutrient deficiencies
in some of our plants. In particular one I’d like to talk about today is something called
iron chlorosis. The symptoms of iron chlorosis are yellowing of the leaves while the veins
still stay green. It’s also called inter-venal chlorosis. Now it’s different than nitrogen
deficiency, in that nitrogen deficiency the entire leaf turns yellow or a pale shade of
green, including the veins. Nitrogen deficiency also shows up more typically on the older
tissue. Iron deficiency will show up on the newer growth. Manganese and zinc deficiency
has a very similar symptom to iron deficiency, but it will also show up on the older tissue.
This you may see on trees, you may see it on strawberries, and sometimes other plants
in the garden. So what can you do about it? One is to make sure you don’t overwater
in the spring. Overwatering in the spring can really make the conditions worse. It’s
important to adjust your watering system seasonally. Another thing that can make iron deficiency
worse is compacted soil or low organic matter. So by adding compost as a mulch or incorporating
it into the garden, can make a big difference as well over the long term. Another option
is to either fertilize with iron or attempt to lower the soil pH in your garden. So take
your soil from an alkaline down to a more acidic soil. If you’re going to attempt
to do either of those it is very important to do a soil test first. I’m Caitlin Youngquist,
