Meiwa kumquat grafted Flying dragon will ripens in 4-8 months. The ripening timing might be off.

That is a good idea. What do you mean might be off? Like they will all ripen at random times, or all the fruits will ripen at different times each year

They tend to flower early summer and might not ripen till November. planting them inground in the greenhouse would allow for warm soil to provide the root warmth to ripen the fruit. It is important to get them grafted to Flying dragon or poncirus trifoliata. Onegreenworld.com uses flying dragon.

I need the greenhouse for other crops in the spring to fall months. Is there a way I can manipulate potted trees to bloom at certain times? Im trying to figure out if I can make them bloom a certain time, if I would then be able to harvest in September and October. November here gets too cold and will damage the fruits on the trees I would imagine.

If you need Winter temperatures to be lower than 50°F for economic reasons, the trees can be induced into dormancy if they are on Poncirus rootstock. Covering the structure too early is ill advised, as is covering with clear film only.

I enclosed my trees at the last minute, usually in mid-November. Mine are covered earlier with clear greenhouse film. About the same time as the surface of outdoor soil slightly freezes for the first time, I totally enclose the structure will 70% opaque white overwintering film. This is installed on top of the clear film. The ends of the structure are enclosed with the white poly at this point. The white poly is the only end wall covering.

On unseasonably warm days the structure is vented to prevent overheating.

I have been working on early flowering trickery growing practice. So far no results. Kumquats Flower when the day is long with no change from day to day (summer) June 21. you can provide the tree light and warmth with artificial lights while lengthening the on period till April then set for same length for a month and hope the tree gets the message

The citrus tree pots can be set in a hole to keep the roots warm and then removed for spring planting. The hole can be placed in the walk way and can be covered during summer use.

Herman is there a way i can message you. I'd love to pick your brain. I'm at a loss.

So far i have considered growing Citrangequats, Sudachi, Early St Anne Satsuma, Xie Shan Satsumas. They all are ready to be picked in late Septembe to mid October. I was planning on putting them in the hoop house then putting a cover on them and adding Christmas lights when temps hit a certain
