While at first glance this may look like your classic excessive moisture symptom, after looking a little closer it actually appears to be quite the opposite. Considering the chlorosis is mainly present on the inter-veinal parts of the foliage I ruled this out to be a nutrient imbalance instead. Most likely deficient in either iron or manganese since the chlorotic areas are between the veins, while the veins themselves remain green. It's also common for manganese deficiency to cause dead spots and patches. <b>How could this happen?</b> I have a few theories:<div>1. Excessive rainfall could've washed away the nutrients from the soil.</div><div>2. Period of drought; plants need water present in order for the roots to extract available nutrients in the soil as soluble salts.</div><div>3. Nutrient cycle above ground could've broke. Right next to this small group of plants was a very large tree that was clearly deceased, with only some growth left at the top (probably 60 feet up). Since nutrients can come from dead leaves, wood, and animal droppings that break down in the soil- the presence of this matter being significantly decreased could've contributed to these symptoms.</div>
An indoor cactus likes nothing better then a good South facing window, and as you can tell I have definitely took advantage of mine! Did you know there is close to 2000 species of cacti out there in the world?! From desert, jungle, grafted, to hybrid species ranging from a diverse amount of colors, shapes, and structures.<br><br><b>Care Guidelines to Follow:</b><br><ul><li>Light is key! Make sure your cactus has plenty of exposure to full sun, or at least bright indirect light.</li><li>Best to only water once the soil has dried out completely, however, some jungle species may need to be watered when half the soil has dried out (considering they are from a more tropical region).</li><li><b>Tip</b>: If your cactus is exposed to full sun for most of the day it'll be best to check the soil often to monitor how frequent it takes up water. As soon as it has dried out it'll be ready for a drink; although they may be drought tolerant they can certainly decline from too much sun and not enough water (especially smaller specimens).</li></ul><br><br>
Out of the 60+ plants I have in my home these guys seem to get all the attention. The Marimo Moss ball- but actually not a moss at all! These guys are actually a form of macro-algae, like aquatic algae or seaweed. Commonly found in cold, freshwater lakes throughout the Northern Hemisphere. Within its natural habitat this algae gets its shape as floating pieces are caught within the current which rolls them around; ultimately resulting in the spherical shape you are use to seeing. But did you know that this is not the only way they grow? A large number of them can also be found growing on lake beds creating almost a carpet like appearance; covering everything from rocks to debris. <br><br><b>Care Guidelines to Follow:<br></b><ul><li>Keep in an open container to allow fresh air exchange.<b></b></li><li>Low-bright indirect light will do just fine, but avoid direct sun as this can scorch the filaments.</li><li>Always use cold water, and replenish every 1-2 weeks depending on algae growth (dirty water).</li><li>I always recommend rotating these guys daily, or every other day. This will ensure that all parts are actively photosynthesizing, and will also help maintain its shape. </li><li>When changing the water I also rinse each Marimo to get rid of any debris that might be on them. I then roll them in my hands to help encourage the round shape in case any have started to unravel (which is perfectly normal since we can't provide those natural currents that roll them). Therefor, we gotta do what we can do help them out!<br></li><li>Ever notice the Marimo browning? This could occur if one side hasn't been exposed to light long enough. Or if it's very dirty. Adding some aquarium salt to the water may help bring back it's greener hue! </li></ul>
My button fern(<i>Pellaea</i> rotundifolia) has recently moved into my shower! Since ferns love humidity and crisp up very quickly this is the only place in my house during the winter where she stays a little happy.<br><br>Any other humidity ideas?
The clearance section in most garden centers is a good place to find inexpensive plants that are otherwise overlooked! Once you address how much damage is done, and what you can do to cure it, you can save a plant!<br><br>This elephant bush(<i>Portulacaria</i> afra) was severely dehydrated and had compacted soil. Simply aerated and saturated the soil and was back to good health!
