Why is my Japanese black pine still yet so small?
They will be 2 years old in March(germinated myself) and they haven‘t even topped a foot tall yet. Could they possibly be a dwarf? The color is also not lush green, it’s more yellowish and it’s like that the whole year.

Comments (3)As soon as they've sprouted, but don't stick them straight into Texas sun til they're a bit older - Oct. might be good, in light shade at first, then only at midday after about 10 days and watch out because they'll dry out fast (even if mature ones prefer a drier mix). They should only ever be in the mix to begin with, never in water, and always watered from the top. Remove the cover as soon as they're a couple of inches tall. If you want to keep up humidity around them (I might not have undertstood your set-up) by all means do so, but don't let the roots ever sit in water. Hard to say about the broken ones.... generally another top branch will take over once you tie it to what's left of the trunk, but your trees are way too small for that, so just be patient....See MoreWhy is my Japanese maple turning green?
Comments (46)I’ve read all the comment from the beginning in 2010. Found some Tamukeyama Japanese maple at Costco that are being stored inside in a corner. 10 gallon pots. The leaves are partially green and it is looking like it’s not getting enough water or sun. Not looking great. My question is if will it come back to red if I plant it in the right conditions. ( next to another Tamukeyama that is doing great)? Thanks!...See MoreJapanese Beetles, bizarrely small crop this year so far...
Comments (36)This article does not have a date. "Several natural predators eat Japanese beetles. Among birds, only starlings eat the beetles, but several others eat the larvae in the spring. Several beneficial insects including Assassin bugs and Tiphia wasps attack Japanese beetle larvae." "Alternatives to pesticides for lawn grubs include: (1) Milky spore disease. However, it is not very effective in New York State except on Long Island, since our cold winter temperatures kill off the spores in winter and successful treatment depends upon a build-up of the disease. (2) Although research is not yet totally conclusive, a better choice to try is the parasitic nematode, in the Steinernema species, which seem to provide some control. Watch for information on beneficial nematodes becoming available for Japanese beetle control, as future research progresses." ----------------------------------- H. Kuska comment: In northern Ohio I use both Milky Spore and beneficial nematodes. I get some beetles but not enough to be concerned about. Here is a link that might be useful: link for above...See MoreJapanese Black Pine
Comments (6)A few years ago we had a couple small mugo pines on our property. One year I noticed one of them was covered in small, 1" long green and black worms. Turned out to be sawfly caterpillars. We used an insecticide and got rid of them. Or so we thought. The next year ALL of the mugo pines were covered with them. Used insecticide again on all the mugos, killed all the caterpillars. Third year they came back again. We decided to simply get rid of the mugos. Have not seen any sawfly caterpillars since (knock on wood!). TYG...See More

3 years agoI germinated them in March of 2019 and repotted in Spring of 2020 in 5-1-1 mix. I had to bareroot it because the 2 seedlings we’re all tangled up in their original pot that they were in. The root system was massive and deep so I chose the 1 gallon container to repot. I kept them in more shade than sun for the beginning of the season because they were just repotted but put them out in full sun later on. I made sure the media didn’t dry out but did take it away from forecasted rain if they were still moist as these species like dry better than wet. I never fed them yet because they were still in their first year after being repotted.
I bring up my concerns with this because in 2017 I ordered several 1 year old pinus thunbergii seedlings from a nursery and they were definitely bigger than my pines now. Why were their pines considerably bigger than mine right now when my pine is older than their‘s from back then? Here is a pic of that 1 year old pine seedling I received 4 years ago.
