green algae growing inches into the soil?!

<p>So I planted a baby rosebush in about April in this transparent organiser box … think the type of organiser box your child would use to store things away from college – 4 - 6 gallon box? </p>

<p>The thing is, I made it transparent so I could check the condition of the roots. Punched some holes into the bottom of the box. It was difficult to do, I was being stingy, so the holes are quite small (5 about evenly spaced, about 7 mm in diameter each), but it does drain … copiously sometimes, the thing I don’t know if it’s enough. From the color of the soil, there’s always wet soil at the bottom and sometimes it takes days for the wet/not-so-wet boundary to go down.</p>

<p>Anyway, putting it into a transparent box is an interesting diagnostic tool … but I don’t know if allowing sunlight to reach the soil makes for interesting soil conditions. Recently I’ve been spotting green algae-like growth growing in the soil and at some portions it appears to intersect with the roots! And I only have a 2D view so I can’t tell if there’s root rot or not. The plant doesn’t show symptoms of it yet (other than holes due to lots of aphids and caterpillars I didn’t catch earlier) – no leaf dropping, no yellow leaves. </p>

<p>Also, are there easier ways to take care of aphids other than manually wiping them away by hand with a wet paper towel? Sometimes I have to reach really tough-to-reach spots … like the joints of two stems.</p>

<p>I think malathion (?sp) will take care of aphids.</p>

<p>Do you burry the box in the ground? If not, be careful about having the roots bake in the sun. It can get quite warm in the box. Roots are not designed to take the heat.</p>

<p>I’m guessing since you are getting algae that the box is not buried. Allowing sun to reach the moist below ground soil will encourage algae growth that otherwise would not happen.</p>

<p>Damp soil is ok. Prolonged Wet soil could be a problem - mold growth, air not getting to roots down there, etc.</p>

<p>algae growth is a result of light & moisture. Aphids use a spray of soapy water not detergent or you can use trained ladybugs or orthene spray.</p>

<p>I like to take small plants into the shower with me to give them a good bath. Or use the sink sprayer.</p>

<p>Alge = Light + water.</p>
