I live in Lithuania and now it's cold there only about 10-15 C in the kitchen,and before few weeks I've planted some seeds of mandarin,grapefruit and orange. Will they sprout later or it is too low temperature? In spring when weather was warmer I was planted lemon seed and now it's sprouted and it has 6 leaves and 3 baby leaves, little seedling doing well I think. But what about others citrus, will they germinate? Let me know any tips on growing citrus trees. Sorry for my bad grammary..
Citrus seed are normally germinated at 86 to 90F (30 to 32C). At these temperatures a citrus seed should germinate in approximately 16 to 23 days. Citrus seed will still germinate at lower temperatures, but will take longer. At temperatures below 64F (18C), the seed might rot before they are able to germinate. Good Luck. - Millet (1,189-)
