Hi
@Huicho! You may consider using a physical barrier, I've managed to build some great protections with plastic bottles (for seedlings), or using tarpaulin around stakes for bigger plants. If you want to prevent slugs & snails from eating your baby, a beer-trap would be a good way to attract them away. You need to mix some flour in beer in a shallow container (split a yoghourt pot in its height) and push it into the ground, so the invaders can fall into. For thrips & spidermites, neem-oil is one of the best organic repellent, mix 12~15 drops of pure neem-oil in a liter of water and spray this solution onto your baby at night or in the early morning. Finally, you can plant some flowers & aromatics in your garden to attract everything away from your Blueberry. Prevention is the key. By multiplying your approaches, you'll win this fight and be rewarded soon ;-) Hope this will help, keep us up-to-date and happy growing! 👊
