For the first time EVER both our beets and chard wilted at the stems and literally dissolved into the ground. Searching online our best guess is bacterial soft rot -- we square foot garden and the blocks were at opposite ends of the garden and all our other vegetables seem fine. Beets and chard come from the same family. We dug all the diseased plants up and put into garbage bags (not compost) and got rid of it lock, stock and barrel. Do you have any thoughts? Thanks!
There is a disease called beet vascular necrosis caused by Pectobacterium which is also referred to as bacterial soft rot. This could possibly be the cause, however this disease can infect other vegetables so I wouldn't expect the beets and chard to be the only ones hit.
You may want to check the website of your local agricultural college or its extension service to see if they have a guide to beet diseases with pictures. The most common diseases vary by region.
Overnight two nights ago, a yellow blob, foamy looking, appeared between an old rose and a bunch of lilies. It is about 25 cm (10 inches) long by about 7 inches wide. The color is light sand. Any one has an idea what this could be and come from? Thanks
This is a slime mold, a colony of unicellular creatures that many people mistake for fungus. It is actually more closely related to amoebas. This one is probably Fuligo septica, which can be white or yellow.
Fortunately, they are harmless. But if you want to get rid of them, this article has some ideas:

Do grubs eat flowers/plants also? I had beautiful (4) azaleas in the spring and (10) impatiens all summer long. The (1) azalea died early summer and had to be replaced and then an impatiens plant died, now another impatiens is dying for no apparent reason. The other azalea plants and impatiens are fine. Since the ones that are dying are in the same area of the bed, is it possible that grubs are eating the roots? Thanks so much for your input.
Have you seen the Grubs in the soil?
Plants can die off from many different reasons; pests, disease, or environmental issues.

Why am I having problems with my Cantaloupe plant and my Yellow Squash? I had to pull from the garden because it died. I am having problems with growing watermelon and they died. Everything I grew in the vegetable garden had some plants that made it but the ones I mention above.
It sounds like all the plants you are having problems with are cucrbits, members of the plant family that includes squash, melons, and cucumbers. These plants can be infected with many of the same diseases, so maybe a cucurbit disease struck your garden.
Check whether the symptoms of the plants match any of these descriptions:

In any case, remove all the dead plant material to make sure disease won't spread. If there is a disease, it is best to not plant any cucurbits for the next two years and focus on growing other plants.
Gorgeous large, lush, green leaves w/silver spots. However, only a few flowers in my container garden. I use a natural, organic fish-fertilizer of 5-1-1. I purchased the rhizomes from QVC, which sprouted quickly. Lots of blooms after a couple of months. Now only a couple. I plan on bringing them in for winter to replant next spring.
You may have to much Nitrogen in the soil. This will cause lots of lush greens and few flowers.
You can add Phosphorous with a Bone Meal fertilizer.
Here are a few links for you.

I have bought several plants that turn red in the fall and they don't turn. They just brown and die out - even the creeping ivy I took from an existing plant that turns red doesn't turn red in my yard. Is there something I can add to the soil that can help it along? ?
If your plants are turning brown and dying off, you may want to check the growing conditions that each particular plant needs and if your garden is meeting these requirements.
Check soil, sunlight and watering.
A soil test will help you determine if the nutrients in your soil are adequate or if you need to amend the soil.
Your nearest County Extension Office can help you with a soil test for a small fee.
I've included a link to help you find the nearest office.

If my perennials have powdery mildew now as they are dying back, does that mean they will have powdery mildew when they come up next year?
It is very likely that the Powdery Mildew will occur, due to growing conditions or plant type.
