Great question! Summer might be cutting it close for air layering plum and apricot trees, but it’s not necessarily too late to give it a go. June or early July are generally your safest bets, as these trees are actively growing during this time.

Here are a few tips to boost your chances of success:

1. Moisture Management: Summer can be hot and dry, so make sure the air layer remains moist—like keeping a sponge in perfect suspense.
2. Shading: Direct sunlight can be a scorcher. Provide some shade to the air-layered section to prevent it from drying out.

Happy air layering! If it doesn't work, you can always try again next year and give your tree its proper “haircut” earlier. Cheers from bonsaiz.com! 🌳🍑
