Avocado Plant

The winters in MN are way too cold. You will have to bring them all in, or you will loose them. I have a hibiscus I bring in and put in the basement in a room that faces south and gets a sun light. I let it go dormant and only water it about once a month. Once spring comes I bring it up stairs and start fertilizing it and water regularly. I would google the 3 on how to over winter in doors. Good Luck! I would love to hear how you grew the avocado seed. I have tried but was never successful.

Bring them in before the frost.

All must be brought inside ....any exposure for any lenth of time to temps below 32 farenheit will kill them

To root an avocado seed: you need a glass or vase just slightly larger around than the seed. Take 3 or 4 tooth picks and stick them into the seed in an X, about 1/ to 3/4 of the way up the seed ** Point side down ** Rest the tooth picks on the rim on the glass so the bottom, part is in water. Keep the water level up until the seed splits open and the new little tree is about 6 inches tall and has a good set of roots. PATIENCE is called for and keep the bottom of the seed in the water.

DEFINITELY BRING THEM INSIDE! Put them by a sunny window and only water when they begin to feel dry (it is easy to over-water indoors). Applications of CITRUS FOOD will do wonders for your lemons and other citrus. Citrus flowers and fruits in the WINTER MONTHS - and you will hopefully be rewarded with wonderfully smelling flowers and maybe some fruit - but thin fruit by half if needed so they will be nicer. You'll have to 'pollinate' the flowers yourself with a soft painters brush or a q-tip. We had a wonderful 3-foot lime 'bush' that was covered in key limes every season - during the winter. BTW - you can leave the fruit on a citrus tree for a long time - weeks or months - and it keeps much better than if you picked it and refrigerated it. Limes are much 'sweeter' and flavorful if you allow them to ripen to yellow. See lots of info on YouTube and Google for more about growing tropical/citrus plants indoors.

Just as an FYI you need 2 plants for avocados to bear fruit.

Repot every plant in the next size container.spray all the leaves over and under with horticultral oil,bring inside and place in the appropriate lighting locations

FYI.. you need 2 trees/plants for the avocado to produce fruit
