They are vines, and they will lie down and crawl when they get top heavy. Even the bush varieties are just vines bred to be short. Seems to me that patty pans and Zephyrs don't have as thick of stems as the long Zucchs, and may flop sooner. Hope they bloom soon and give you squashes enough to make you a "bad neighbor" (JK) ;-D Good Gardening! :-)

transplanting can slow down squash, but I grow several every year and always transplant. Even my giant pumpkins get transplanted after it is 2 feet tall and wide. Transplant carefully and you should have no problem. It looks to me like maybe too cold and too wet. ? Where are you located? I am on the coast of British Columbia and this (last week of May or first week of June) is when I set my plants to ground from the green house. Don't fertilize until they show growth. If you can put a cover over them that will help to warm them up but DON"T burn them!. You need root growth in June. Taking off the first few flowers will let leaves and roots develop. Leaves and roots are what feed the fruit.

I've got lots and lots of plants from that family growing. They seem to do really well for me when planted in mounds of mushroom compost and provided with good drip irrigating to keep the roots moist and cool. Only struggles I seem to have with them is potassium deficiency which tends to make them more prone to powdery mildew and I'm trying to combat with maxicrop. I have also had some trouble with caterpillars, vine borrers and squash bugs (actually several types of bugs in the same general group squash bugs, stink bugs, and leaf footed bugs) but there is little to be done about them. The caterpillars I can battle with thruicide. The main problem I'm guessing for your poor little squash might be the vine borrers. They can kill off a whole plant pretty quickly. The moth (or whatever it is) lays an egg near the base of the plant or along the stem. When the larva hatches it eats into the stem and then eats along the inside of the stem killing any part of the plant above the larva within the stem. They can cause really quick death of a plant if they start boring in near the base of the plant. You may find a hole near where a leaf meats the stem and if the whole plant isn't already dead, you can use a pin to stab the larva inside the stem or just split open the stem to find the larva and kill it so it can't develop and re-produce. BT or thuricide isn't very effective against vine borrers since they only eat a small hold into the stem and then are safe inside the plant. BT only really works if the caterpillar eats the stuff. The comments about the sun are good. Most squash and cucs I've known don't like complete full day sun though I have some doing ok in mounds of mushroom compost with drip irrigation in my back yard (however they were direct seeded and not transplants.)

Welcome to the world of veggies! Never have much luck with zucchini. Always get taken by borers. (Blueridge - what kind do you grow? Mine usually seem to be a bush type rather than a rambler...but that may be because they die too soon.) I can generally get close to a couple of dozen peppers off of one plant. I cage my tomatoes, but I usually just grow a couple of romas and a few better boys. I generally pinch them in the beginning to make them bushier, but once they reach the top of the cage, I just let them tumble and go where they want. They're in a 4x8 raised bed. Tip here - toss a handful of lime in the hole when you plant them. It will help to prevent blossom end rot. Also, if you want more plants, don't go buy them. Just cut off a branch, stick it in a jar of water and in about a week you'll have roots and you can't plant it.
