A question came in this week about scale:
"I have two large tree mallows (grown as shrubs) with a very heavy scale infestation. A local nursery recommends using a petroleum oil spray. Is there another effective, greener solution?"
Yes, I can definitely suggest an alternative to petroleum sprays, but first - a little understanding about what scale is:
Scale is an insect, but it looks and behaves more like a mollusk. There are soft ...
Here's a recent question that came in last week:
"I have lots of shade but some sun in my front yard. Combination of city trees, large bushes I don't want to part with etc. I seem to remember a device that one can put in a spot to determine the amount of sun it gets per day. I want to try to incorporate veggies into the landscape and this would help tell me where. Do you know where I might find this and ...

It's getting busy here at Ask Gardenerd this week. Here's another question that came in:
"Is there an easier way to keep the weeds down in my flower garden besides using preen covering, & then putting wood chips on top of the preen?"
Hi there,
I'll admit, I actually had to look up Preen because I'd never heard of it. I see that you're talking about a corn based weed suppressant, correct?
Okay - so there are two things that help weeds grow: water ...
A really interesting question came across my desk today:
" Hi I am not sure how to put this but I think I got ripped off. I hired a guy from a well known garden center to help me build a raised 8x10 garden that I had last summer (not raised) so he advised me to buy 36 total bags of soil including manure,etc. Yet there was not enough and had to buy more, ending up with 50 bags and cinder blocks. The soil is ...
Here's a question from a former student: "Hey Christy,, I took your Organic Gardening Class at SMC a few months back and I am well on my way to creating my first Organic Garden!

I think i will grow garlic also."
Thanks Theresa, we had fun putting that garlic braiding video together. Now, about your picket fence...

It's spring, and everyone is out in the garden. This question came in this week:
"What type of material do you use for constructing raised beds? We've done some raised beds in redwood, but we are concerned that they will rot. What is a safe and long lasting sealer to use for wood raised beds? or are there other economical composite materials to use in constructing beds? Thanks, Yasi"
Great question, Yasi. I've built raised beds out of many different ...
Another great question came in this week:
"Hello, I have a worm bin that I use to throw all my compostable items in such as veggies,eggshells, paper etc. I also have a big compost bin next to my worm bin, it is about a quarter full. I throw junk mail and grass clippings, tree clippings, whatever is too big for my worm bin goes in this big bin. Could I add worms to this big bin as well to aid in the speed of the ...
It must be that time of year again... here come the questions about aphids:
"The leaves on Russian kale plants have a gray aphid looking bug on them. They cluster on the leaves. How to get rid of them and keep them off. Water doesn't seem to do much."
First of all I have to say that if you planted your kale in fall, the plants are probably just finished for the season and should be pulled. My kale plants bit ...
