    I don't believe the garlic played any role in the loss of your Rhubarb.
    Did the plant go to seed? This can rob the rhubarb of nutrients.

    Here is a link about Rhubarb.

    Overcrowding will significantly reduce yields and even lead to other issues, such as fungal problems from lack of air circulation. Therefore, digging them up and dividing the plants will greatly help, keeping them spaced apart at least 3 feet between one another. This article will help you with dividing:

    It depends on the variety. Some varieties should be red when harvested, while others should be harvested when green because the stalks never turn red. If you have a red variety, wait until the stalks are red to harvest. Here is an article that you may find helpful: https://www.gardeningknowhow.com/edible/vegetables/rhubarb/harvesting-rhubarb.htm

    You should be able to find both liquid and or granular forms of copper compounds.
    Your local garden centers or garden sections of a home improvement center will carry these products.

If you have a red variety, wait until the stalks are red to harvest. After harvesting, you can trim the plants back or leave them alone until after winter.

    Not all rhubarb stalks turn red. There are many cultivars of rhubarb - the color depends on both the cultivar and how it was grown (rhubarb favors cool temperatures and abundant sunlight). Here are some links with more information:
