How Much Mulch?


Ever wonder how many bags of mulch, soil, compost or gravel to buy? Would it make more sense to have a yard of material delivered? Or will you need that much? End the guesswork.  Measure your space and use this table to calculate how much to buy.

How Do You Say Yucca?

When I was studying landscape design, most of my fellow students regarded Yucca plants (Yucca filamentosa) with contempt. YUCK-a, they would say.
And with good reason. The foliage can look pretty ratty and grooming is difficult because the leaves are sharp and tough. If you decide that you want to remove the plant altogether, you have your work cut out for you. If you don't get all of the fibrous root out of the ground, it will sprout "babies," and you'll have to go at it again. I suspect that one reason we see so many unkempt clumps of Yucca plants is that people get tired of trying to dig them out, so they give up and let them continue to multiply. Thus adding to the YUCK factor.
But on the plus side, just look at these flowers! Borne on stalks that can reach 10 feet high, they are a striking addition to the landscape. In addition, yuccas are tough plants that can handle drought and salt spray.

Y. filamentosa, or Adam's Needle, is the cultivar seen in Seattle gardens. There are many other varieties, including Y. brevifolia or Joshua Tree, all of which require warmer climates than we have here.
