I have a 8' pentagon shape garden where I planted 4 blueberry plants and 7 sweet cherry bush (dark fruit), I did nothing to my red clay soil and the plants were ok for their first year (planted in fall 20110,but they are not yielding desired amount of fruit, I know the plants are still young, is there anything I can do to the soil to help with the growth?I have a bag of fertilizer and some alpaca pellet from friend, can I add them to blueberry and bush cherry plants?
Thanks!
