At GreenShack, we typically advise reserving a temperature between 65 and 85 degrees F. Of course, avoid positioning your Acer palmatum’Bloodgood’ close to air conditioners, radiators, or other sources of hot or cold air.

Keep your ‘Bloodgood’ Japanese maple Dust-Free

For your ‘Bloodgood’ Japanese maple, this would be a true descent into hell, and it would also appease the pests.

Take a microfiber cloth and gently massage the plant’s leaves to get rid of the dust. Use a damp cloth to make dust removal easier, but avoid using corrosive materials like rubbing alcohol!

Keep drainage in mind

If you have a tendency to overwater, you should be mindful of your drainage, and if they don’t already have them, we suggest selecting a saucer and a pot with drainage holes.

If your pots don’t already have holes in them, you can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the meantime. This will assist in creating a channel and keep the water from pooling there for an extended period of time, protecting the roots from decay.
