Why am I losing many blossoms from my veggie plants?
Blossom drop is usually caused by stress. Too much water or too little will upset the plants natural rhythm. High temperatures can also cause problems. Finally, poor pollination can lead to blossom drop. If the plants are not properly pollinated, their blossoms/small fruit will drop off.
I have a small garden that my daughter and I created and we would like to plant some vegetables. Is there anything we can plant now?
Yes, it does depend on your location. These articles should help: https://www.gardeningknowhow.com/edible/vegetables/vgen/fall-vegetable-gardening.htm

Obviously, it depends on where you live. I'm in zone 6, in Washington state. I have lettuce, spinach, kale, cabbage, carrots, beets,onions, mizuna (a type of mustard), and will plant some mache (also called corn salad) in a few weeks when the weather cools down. Most of these plants were started in my kitchen from seed about 4-6 weeks ago, and have been transplanted into the garden. It may be too late to start something from seed at this late date and could be difficult to find seedlings in nurseries this time of year. Most cool weather crops sprout and start to grow in warm weather but need cool weather to mature. When the nights start to be cool, I make hoops and cover with fabric row covers, then when the weather gets cold I cover with a second layer of clear plastic. Usually I have veggies well into January.
How do you rid unwanted volunteers from previous crops in your vegetable gardens?
You don't say what kind of plants are volunteering. The general answer is don't let the plants re-seed. For example, don't let tomatoes or peppers stay on the ground if they fall off the vine. They will re-seed easily. There are some veggies that you eat before they flower, onion, carrot, garlic, etc. if they flower you should pick off the blooms so they don't set seed. Also, if you make compost be sure it gets hot enough to kill the seeds. A mulch of grass clippings or shredded leaves will retain moisture and reduce weeds, including volunteers.
They are about 3" high already. I know they'll get top heavy. I want them to leaf out, but I just have top and stem now.
It sounds like your seedlings may be leggy. This is caused by a lack of sunlight. This article will help:

I just started a garden, first attempt. They have yellow leaves. We water the garden on a set time 2 times a day.
How to distinguish between bacterial wilting and fungal wilting in vegetables.
You would need to have the vegetable in question tested for pathogens. Contact your local agricultural extension office.
I already know of legumes, but I don't remember the other families. I want to know this so I can order my crops into these groups for my own crop rotation plan. A list of common plants with their families would be very helpful. I also know there is more than just four, as stated by the 4-year plan, and that if we know of all the families we, the home gardeners, can organize our crop rotation. I'm sorry if I have repeated myself. I just want to make sure I cover the bases I'm after.
