Finding God in the garden
Chillin' In The Garden
More likely that they didn't have the root systems to mine for water deeply when it got really hot. I never water anything here....don't know how dry your spring weather gets where you live, but here we get spring rains and then they taper off, causing the plants to put down deeper root systems to mine for water and nutrients.
Folks who water from the beginning usually have to keep watering, as the root systems stay shallow and small because of it. For trees, in particular, this can be a death knell in these parts...then again, not sure what it's like where you live or the nature of your soils, but around here we have clay based soils, which holds a good bit of moisture down deep...the roots have to be strong to get through it, so watering them early and too often prevents a strong root development.
The use of good compost and a deep mulch should hold enough moisture for potatoes to survive without watering unless you live in a very arid, dry climate...even then, the BTE method is supposed to help preserve moisture to the roots of the plant.
Not sure about milkweed bugs...never heard of them...from what I could find, they are a beneficial bug in the garden, so maybe they weren't eating your spuds? Around here we usually get flea beetles or the Colorado potato bug, along with Japanese beetles, that prey on taters. A good spray with soapy water or a dusting with lime really helps with all of those.
They only have to be inside long enough to germinate, which for tomatoes means a couple of days. Depending on your weather where you live, you can then transfer them to a place outside where they get a lot of sunlight for most of the day and cover them with something like I've done...Agribon or a white sheet, which will protect them from getting too cold and/or too hot. Some people will use 4 mil opaque plastic but it won't let the rain through like the cloth. The white covering gives them a better exposure to the sunlight~maybe diffuses the light?~ than they will get on a windowsill, so you won't get plants quite as leggy as you would otherwise.
I even did pepper plants outside this year under that tunnel and they did better than I've ever seen any of my peppers do before.
We had temps down in the 40s and even a couple of times into the 30s when mine were out there this spring, but the Agribon kept them protected and warm.
Another question I have is I'm not sure what "normal" dying back on mature potatoes looks like vs. an infection or some other problem? When do I attempt to harvest? Most of my early variety potatoes have started flowering already too.
We are mostly clay here too in Oklahoma. I think we're like a silty clay on our property at least. It's difficult to get things mature enough around here before it gets hot. I've heard tomatoes won't produce well over 95 degrees which might be a problem here. Many times the highs here are in the 90's 90% of the month of May and then June, July, and August we have 90's and 100's then starts a gradual cool down from September on. Usually May and June are the rainy months here but haven't had a whole lot of rain this May. That's why I've been so surprised about all this fungus I've had on my apples and potatoes.
The only reason I watered was because they looked to be getting a little yellow-green (maybe they were just nutrient deficient or something but Ill try not to water as much next year and for the rest of the year on my remaining potatoes.
There were large numbers of what I believe were Milkweed bug larvae all over my potato plants. The first time I caught them I pulled off probably 50 of them and plants that were infested had large amounts of leaf damage. The only other culprit could be the pill bugs/sow bugs/Rollie pollies. We have no joke probably 10's of thousands of them in the garden and right around the garden and I've heard some people blame destruction of some crops on them but most info I read says they generally only eat rotting stuff or dead stuff but don't actually kill anything.
