How do I get the best yield of veggies from a planter garden?

I would make sure that u keep the soil airated since tilling isn't needed. Make sure water amount meets the suggested level for each plant variety.

Hello Noreen, Start with proper drainage in your pots. They should have holes in the bottom for extra water to escape. If they don't have holes, you can put rocks in the bottom of the pot and put a layer of newspaper over the rocks. Then the soil and the plant. If roots sit in water, the plant will fail. Your tomatoes should have a cage over them. They need that structure for support as they grow. Most vegetable plants need full hot sun. Hope this helps you. Good luck and Happy Gardening.

you may have to fertilize a bit more often as water will wash it out.

i like a time release fertilizer for my veggies. There a varieties that will feed for 6 mo. I generally mix my own potting mix as it's less costly when I'm filling 20 to 40 planters. I mix the recommended ratio of fertilizer to potting mix. The one I use instructs to use 1scoop for a 2 gallon pot And will feed for 6 mo. just follow the package directions for what fertilizer you have. To much may burn your plants. Tomatoes, egg plant may need a boost of calcium...tums, bone meal, lime are all calcium. A table spoon of epsom salt will help set blossoms that start the fruits. It's magnesium...not table salt. Don't reuse the potting mix at the end of the season For more tomato plants next year. Use the old potting mix to fill in low spots in the yard. If you get black or brown spots on the blossom end of the tomato. Add the extra calcium.

the fertilizer has number nitrogen, phosphorous, potassium 20-20-20 is the ratio.

for a more complete understanding, the site www.cleanairgardening.com as a good article.

the 20-20-20 is ok. the numbers stand for how much nitrogen phosphorus potassium in the fertilizer. these are micro nutrients. gardeners supply co. has an easy to read article "fertilizer basics" it may help.
