Not all of our online products can be ordered together. This is because they become available at different times during the growing season. For instance, if you already have a product in your cart that will be delivered to you in late April, you won't be able to add another product that will be available in mid-May..
What we are asking is that you place two separate orders, with two separate delivery dates.
