Since indoor plants do not go through dormancy, continue feeding. Pay attention to their lighting needs as you live in a very northerly state.

Outdoor plants are those who must go dormant, especially in your zone.

Based it will increase buds. But if it was high in nitrogen you'll just gett more leafng


You could still give it a shot of banana water or some other potassium rich water. I put banana peels in a bucket of water and let it sit out in the heat covered with a lid to brew a potassium tea.i smells disgusting but the buds it produces are plumb. I'll still be feeding one more time jn sept

Yes, you should stop fertilizing houseplants in the fall and winter because they are going dormant and don't need as many nutrients. In fact, fertilizing during these months can be a waste of time and money, and could even harm the plant.
Plants only use nutrients when they are actively growing, which is usually from April through September. During the fall and winter, plants are exposed to less light and lower temperatures, which causes them to slow their growth and enter a rest period. Without enough light, plants don't grow extra things like fruits and flowers, which also require more nutrients.
However, some plants may still need a half-dose of fertilizer during the fall and winter, so you should check the instructions on the plant tag or do some research about your specific plant. You can also adjust your care methods so that your plants can thrive in their dormant state.

my husband gave me a year ago May. I am so thankful my Schefflera, is even alive. I have black thumbs so having this plant even be alive is a miracle. It was a plant someone gave for my sisters funeral in 2010. So I will stop the fertilizer until next March or April. The thanksgiving cactus, is fine it’s just 2 years old, and my husbands plant is nearly holding on. But I’ll stop fertilizing them as well. Thanks.
