PlantFiles is getting a new look! Just in time for spring, we're rolling out a new look for the best online plants database. It will also work with your smart phones and mobile devices, so now you can take it with you on garden center visits or botanical garden tours. Questions or comments? Please post them here.
Yes, a little small to transplant...BUT I would do it before the roots get into that mesh and remove the mesh completely when you transplant them. I am of strong believe that those mesh things hinder plant growth. If you keep the mesh, trim the top as much as you can and slice the sides & bottom.
I have found that the mesh does not decompose and the root system remains very small. Also, over the summer, the soil compacts and the mesh will eventually be above soil level and act as a wick. The roots will remain dry as a bone in the mesh and the rest of the pot will be saturated. All the bedding plants that the nurseries sell have that darn mesh. I trim & slice all of them.
Since I went a nutso with seed orders this year, I went to a wholesaler & bought a case of 72 cell trays and a big bail of professional seed starting mix. I like the trays because I can seed a ton of stuff in one tray & they have a nice size drain hole in each cell that the eraser end of a pencil fits thru to pop out the plug when transplanting. Lee Valley sells a similar tray (deep-root), but they are very expensive. I reuse all my trays.
Ok guys I'm wading in here too.
I take a deep container and bulk seed my larger seeds and when they spout I move them with a bamboo stick, prick them out, to the 72 or 32 deep root trays from Lee Valley. I had my hubby cut off a large nail so I can use the head to push out the plant when I transplant them to bigger pots..
I too use the pro starting mix and have had great success with it.
DawnLL I'm not sure if you moved your lights up to take your photo's but I have found that by keeping the lights as close to my plants as possible I reduced the "bolting" that can happen. I try for 1 inch above and I am doing 14 hr timers. That may help contain your plants in their current state. After they are all gong I also have a fan to move the air around, not pointing at the plants.
Everyone I have talked to has a suggestion and I try to use what works for me.
yep or when the supertunias send out long shoots , by pinching them off you do make a stronger plant it will also force branching at each leaf site that is still attached to to the plant.
It sure helps with the longer branches being taken off because they get twisted with each other when they are all growing together.
my sister told me I was nuts because last year as I was planting my annuals I pinched all of them so she had a bloom ten days before me but I had three times more blooms than her at the end of three weeks lol
Well I do have some longer branches but they are down low at the bottom...do I pinch those back? I don't find there is much height to them but they sure are branching out at the bottom...not sure what to do...
in zone four you should not put the petunias out till the first week or second week in june since your frost date is about that time check to make sure since annuals do not do well planted before a week after last frost and perennials can start to go out mid may Im zone 5 and I just started to plant the perennials that are bigger like about six inches tall so a bit of cold wont do much to them now but kept the small ones inside and will not put them out till the end of next month
JUNE!!!, No Way. I can't wait that long. I put them out by (the latest) the 2 week in May. They actually can handle -1ºC if they are hardened off. Been doing that for years. I usually have all my containers planted & placed by Mid-May. Of course I do cover them or haul them into the garage if we get near freezing temps.
