Hi there, I may have gone a little overboard for someone new to gardening and over the last few weeks purchased five small Japanese maples. They're between 14 and 36 inches tall. Atropurpureum in a 1 gallon container from a garden center Sango Kaku in a 1.5 gallon container from a garden center at a home improvement store Golden Full Moon or Autumn Moon, not sure exactly, in a small container from a local nursery and Shigarami and Aka Kawa Hime in small containers from acer1987 on eBay My biggest worry so far is overwatering them and so up until today I've been sticking my finger in the first few inches of soil to feel if it it's dry and then watering fully until the water runs out of the pots I moved them into. Each pot has at least 8 drain holes that I drilled in and the soil mix I'm using (3 parts potting mix, 2 parts pine/fir bark, 1 part pumice) seems pretty loose, and so the water drains out very quickly. I'll put a picture below of them in their pots with the containers they came in for comparison, in case the pots I chose are too large. I think the pot sizes I chose are pretty good except for maybe the Atropurpureum. The pot isn't much deeper than the one it came in, but is maybe too wide? Anyway, I wasn't happy with my finger sensor so I purchased a pretty cheap soil meter and used that today to check the moisture. In the small pots, the moisture reading pretty uniform from top to bottom between 4 and 5 out of 10, which seems about right based on the moisture I could feel with my finger. It's the same in the upper level of soil for the two larger pots, but at the bottom it jumps up to 10. I was worried that they were sitting in standing water or muddy soil or something, so I dug up some dirt from the bottom to see what it looked like. It's definitely damp and moist, but not "wet" - there's no actual water visible. If I squeeze the soil into a very tight ball I can feel moisture beginning to come out, but nothing really visible on my fingers at all. Definitely no standing water or mud or anything close to that. So long story short, my question is, is that level of moisture okay? I'm guessing it's that much higher according to the meter at the bottom of the larger pots because the roots haven't grown enough to absorb it from that low yet. Should they be moved to smaller pots? They've been in the two larger pots for 5 days or so and have only been getting a few hours of sun in the mornings since the weather lately has been a little unpredictable in terms of heat, so I left them in shade rather than risk them being in hot sun all day while I'm at work. My other question is about some crispiness on the leaves of the Sango Kaku and Aka Kawa Hime. There's a picture of the leaves on the Aka Kawa Hime below, the Sango Kaku has a similar look to its leaves. The Sango Kaku was out in the heat at the garden center and so I think that's why the leaves got a bit cooked. The Aka Kawa Hime was in shipment for 4 days so maybe that's why that one has some browning. Is there anything I should do other than keep making sure to water when the soil gets dry? Thank you so much for taking the time to read what became a fairly long post and for any advice you might have for me!
