The Garden Bug: Daffodils
By Brenda Weaver
To grow standard-size daffodils in a pot, select a 2-gallon size pot. For the soil mix, use 1 part perlite to 3 parts sterilized soil. In the bottom of the pot, over a little soil, place a pinch of 0-10-10 fertilizer (do not let the bulb come in contact with the fertilizer), then fill pot to within an inch of the rim. Try to place 3 or 4 bulbs about 1/3 of the way from the top of the pot. Water every day for the first week; after this, water when the soil appears dry. After blooming, add a pinch of 5-10-10 fertilizer to the pot. This helps build the bulb for next year's bloom.
