davidgoodrich,
Welcome to our gardening community and thanks for the post. We are glad that you found us.
It sounds like you are starting the bulbs in pots and would like to transplant them outside. In regards to transplanting them, that will depend on your area. You generally want to plant them in the ground after the last frost in your area (if you have frost in your area). Ideally, the outside ground temperature should be between 50 and 70 degrees. You will want to make sure that they have started sprouting above the soil before you plant them.
If you have started the plants indoors or in a greenhouse, you will want to transition the plants to the outside elements. This is a process called hardening off the plant(s). If you don't do this step, the rapid temperature / climate change is often too much for the plant(s) to bear. It is recommended to start the process about a week and half before you plant your items in the ground. For the first couple of days, place your potted material in a shaded spot outside (under a tree or even on a covered porch) for a couple of hours (2 to 4) and then bring them back inside. After the first 2 or 3 days, you will want to increase the time that you leave them outside and you will want to incorporate sunlight. You might want to put the plants in a sunny spot in the morning for an hour or so and then back into the shade for the remainder of the outside time (still bringing them inside at night for the first few days). After about a week of doing this, your potted plants will be getting sun for a few hours and shade for several hours in the afternoon. If your temperatures are staying about 50 degrees or above, you can even leave them out overnight toward the end of the week or so of conditioning. If it is very warm in your area, make sure that the plants are not getting too dry. After this process you will be ready to plant. It is often recommended to try and plant on a cloudy day so that the plants are not overwhelmed by the sunlight.
This brings us to your next question, where do you want to plant your newly sprouting bulbs. Hyacinths are rated to grow in full sun through full shade, but they seem to do better in sunny areas. Hopefully this answers your questions. Good luck with the transplanting!
