Helen Chesnut's Garden Notes: How to give potting soil 'staying power' through season

For adding substance, look for an “all-purpose” soil that specifies that it is suitable for indoor use and for seeding as well as for potting in general.

Dear Helen: In the last few years, I’ve been disappointed with the quality of the potting soil I buy, for both indoor and outdoor use. It seems to be without much substance. Can you recommend ways to augment these thin, wispy potting soils?

L.S.

I’ve had many comments just like yours complaining about not being able to find potting soil that suits them. Some types that people had come to rely on became hard to find in recent years.

I’ve always made it a practice to add some sterilized soil with substance to any standard potting mix that I started out with as the base of a completed blend. I agree, most basic mixes lack substance. Adding a weightier soil blend gives outdoor container plantings added “staying power” through the growing season.

For adding that element of substance I look for an “all-purpose” soil that specifies that it is suitable for indoor use and for seeding as well as for potting in general. A potting mix labelled “multi-purpose” is not the same. Always check for “all-purpose” and look also for seeding directions.

Currently, to a mix such as a general-purpose Pro-Mix, I add either, or both, of these two products: Cinnabar Valley Farms Premium Organic All Purpose Potting Soil, which is more peat-like than the other, heavier one — Island’s Finest Professional Premium Sterilized Potting Soil — Tout Usage (all-purpose).

Dear Helen: In a recent column you mentioned harvesting carrots last month and making a carrot cake with them. Would you consider sharing the recipe?

D.J.

I’ve been making this carrot cake from the time my children were tiny tots. The original recipe called for one cup sugar, which I have reduced to one-third cup. The carrots are already sweet and I routinely cut the sugar down or out of almost all recipes. Here’s the version I use. Add more sugar if you want.

Carrot Cake

1/3 cup sugar

1 cup oil (I use grapeseed)

3 eggs, added one at a time while beating

1 to 2 tsp vanilla

1/2 tsp salt

1/3 tsp baking soda

1 1/2 tsp baking powder

2 tsp cinnamon

1 1/3 cups flour

2 cups grated carrot

Mix sugar, oil, eggs and vanilla in a large bowl. Combine dry ingredients in another bowl and add to oil and egg blend. Add carrots. Bake for one hour at 300 F in a nine by nine pan. Optional: Add pecans to the batter.

Icing: Again, I avoid “sugar bombs” such as the usual cream cheese and icing sugar blend. Instead, I mix a little maple syrup (and cream if needed) with cream cheese for topping individual slices of the cake.
