|I wouldn't mix the fertilizers. Both contain nitrogen which, if applied in large quantities, can burn your plants. Use one or the other in the spring just as new growth begins. Apply in amounts as recommended on the package. You can then make a second application of fertilizer in mid-summer. Hope this clarifies things for you.
