Welcome to container gardening. Much of your gardening experience growing in the ground will have to be relearned as you find it does not apply when growing in containers. You have found the right place for getting the help needed. The use of compost and compost tea and worm castings, though still useful will be used a little different. The leaves of your plants are telling you their needs are not being met. The container plant is completely dependent on everything needed being provided by the gardener, with no reserves being available from the ground. All you need is available on this site. Al

I find that my red worms who live outside do really well, so long as the soil is kept moist and they are fed often with vegetable/fruit trimmings. I often will add some partially composted leaves from my compost bin. Although, I find that they do well without much attention in my raised beds that have lots of organic compost, I like to keep one 4ft square bed that is shaded and kept covered with cardboard to add my veggie/fruit trimmings/composted leaves. I go clockwise around the bed to add food and to remove the vermicompost as needed to use in my containers/other beds. There are so many worms in the bed that is necessary to spread the vermicompost out to let it dry out and get the worms to move back to a moister section. Try to use unchlorinated water to moisten the rest of the bed or some that has sat out for 24hrs so that the chlorine has mostly evaporated. Red worms will eat the bacteria from the decaying foods, and I never have a problem with offensive odors ....actually, the compost in this bed smells really good and the plants seem to really thrive on it. I agree that getting these worms from someone in your area may be better as they will have adapted to your local weather conditions. I live in a desert area that has temps from the 20's to the 110's and they have survived many years outside this way.

You can brew worm tea but I have found a better method. It takes months to make worm castings. I have 5 worm bins made from Kitty litter buckets and 2 inside bins (rubbermaid containers). I have a lot of potted plants and hated tossing the spent potting soil (expensive) into the garden. I have 2 compost tumblers and when the exothermic reaction is done I add worms to speed up the process. All bins are raised and have collecting trays. The drippage is the best worm tea. I collect it daily using a turkey baster,bulb syringe, or toomey syringe if you have one. You can collect the tea long before the castings and pour it on your potted plants. I have a 5 foot cilantro that really loved it and have brought back many nutrient deficient plants. Recycling potting soil in worm bins really works too and the worms love them.

Mike, much of the nutritional value comes from the microorganisms growing on the organic material. The tea making process washes away many of those microbes, but not all. If you throw that material back into an active worm bin, I'm sure the microbes will quickly grow and the worms will be attracted to ingest the particles again. Andrew
