The peas definitely look sunburned. They could really benefit from the shade cloth you purchased.

With the squash, I see two problems: first, you've planted them really close together. I would give Black Beauty zucchini 3-4' feet of space for each plant. As for the yellowing leaves, how have you been fertilizing? Squash are heavy feeders anyway, and when you grow in containers you typically need to fertilize more often than you would when planting in the ground.

You'll find the best help for container gardening over on the Container Gardening forum here. It is a very different kind of gardening with its own rules and regs so you really need to check out that forum.

But I agree that your plants appear to be very over-watered and anemic looking as a result. But that appearance could also be from the mix you used to fill your beds as it is not intended for use in containers but to be mixed with native soils in ground. It drains poorly, compacts, and often leads to root rot and stunting. Unfortunately it also contains a great deal of uncomposted wood which binds up the nitrogen the plants need. So they are nitrogen deprived.

There are numerous past reviews here about that particular product and the problems associated with it. Like other garden soils you may find that it says somewhere on the label "not for use in containers". If it doesn't, it should.

But your plants can be salvaged with VERY careful and limited water applications only when the soil knuckles deep is dry and with regular feedings of a well balanced fertilizer - preferably a liquid - to off-set the nitrogen issues. Keep in mind that dry organic fertilizers can only work if there is an active soil food web to digest them. That doesn't exist in a container. So if you wish to only use organics then you will need to find a couple of different organic liquids to provide all the needed nutrients for the plants.

Agree with watring issue. I bought one of these and it really simplified things. Since I bought this four or five years ago, now see them at various hardware, lawn&garden, etc. places. Neat idea, the probe is two dissimilar metals, add soll and moisture and it becomes a battery, the meter reads the voltage produced only converted into % moisture.

Those plants look just about dead to me...only because mine looked the same before they died. The squash leaves grow small and vertically and then die. Start over with less watering and warmer weather perhaps? Good luck?

I don't always water twice a day, only when I feel the dirt with my finger about 1/2 inch down and it is dry, that has been only a couple of days when it has been very hot. I do have a meter, which checks the light, moisture and ph. Light is great, moisture is in the medium range and the ph is also where it should be. I have not given any fertilizer. Thinkin that the organic soil I am using is good enough. Guess I have to re-think the soil mixture....thinking with organic you are doing the right thing, may need to read, right.? Feeling really stupid. Well.....learning as we go. Feel for those poor little dudes, they count on me taking care of them and I'm killing them with kindness....too much. Thank you for your advise.....taken wisely, I will not water every morning, check out my dirt and see if it's too much and keep you posted. I will let ya'all know how we are doing. BUT, my potatoes, carrots and beets are thriving.

You did not buy potting soil. You bought "Garden Soil" which is not a container medium, but is instead blended as an amendment for outdoor garden beds. It has more sawmill scrap ("forest products", as they are euphemistically noted on the label) than the potting soil and none of the perlite, rice hulls, and peat moss to lighten the medium. People get confused all the time because the bags are similarly labeled and right next to each other.

So what to do now is a tricky question. It looks like the seedlings are still small enough that if you chose to you could go get actual potting soil and replant the containers.

Also, you have too many squash in that container. Two plants will barely fit. Don't worry, two plants will provide plenty of vegetables for your family (and neighbors!)
