Karen, they have grown so much that watering is rather often. Especially now, as they
want very much to be outside. I suspect the roots are getting quite large.
The fertilize comes in a 50-lb bag, and is used for lawn, garden, fruit trees, shrubs, etc.
We buy from gardening stores. I don't know if the big box stores carry this. I haven't looked.
Anyway, the bag costs around $10-12.
Hubby just used a pinch of the granules, applying them to the top of the soil.
Then when watered, it gets down to the roots.
On Edit: I don't know the name offhand. We just ask for whatever 10-10-10 product
the gardening store carries in any given year. The brands can change depending on the store
from one year to the next. I'll check tomorrow to see the size of the bag and see if a brand name is on it.
