Some of my seedlings average heights so far:
Tomatoes 3 inches
Carrots 1-3 inchess
Broccoli 2 inches
The broccoli is not supposed to be growing at all because of the heat outside, but it seems to be doing well so far. I have been keeping the soil wet, and providing partial shade as much as I can to it to help keep it a little cooler.
My 2 starter tomato plants are producing green tomatoes, and a lot of them. They have grown over 2 feet since I planted them!
My blueberries are not yet blossoming, but I haven't researched much on when they blossom in Florida... I might have to do a little research on that soon :)
My 2 cucumber starter plants are doing well, one of them is over 10 inches tall, the other is about 8 inches. They are also almost long enough to start climbing their trellis.
Our starter strawberries are growing and we have a few red strawberries on them as well! I don't know if they will ever get all the way red because my kids keep picking them all before they have a chance to fully ripen! I love that my kids are so excited about helping out in the garden, and they run out there often to see if there are any red tomatoes or strawberries ready to be picked.
My celery is growing well in the window seal. It is about inches tall already! I have 2 stalks "re-growing" from the base (see previous blog on replanting celery). I have it indoors because it doesn't grow well in heat, and is a cold weather vegetable. It is growing great so far in my kitchen window. I have had to aerorate it frequently to avoid mold growing because it is growing indoors it needs a little extra treatment. I water it just enough to keep the soil moist, about every other day.
