When filling back in around each seedling after planting it out into its fresh domicile , habituate compost if uncommitted — it helps provide nutrients for intelligent increment and prevents weed from taking over .
Once establish out into their lasting outdoor locations , give your seedlings some spare TLC . Fertilize them with a melted fertilizer soon after transplanting , water deeply every few days during dry spells ; mulch around them ; keep an eye on any pests or diseases that may arise ; stake tall motley like Lycopersicon esculentum if necessary ; prune off dead leave of absence and peak regularly ; and apply fertiliser every match week consort to software instructions .
