How to start a terrace garden from scratch in July?

Buy 10–15 litre pots, fill with 60% cocopeat, 30% compost, 10% perlite mix. Sow okra, chilli, brinjal, and bush beans directly. July rain reduces watering effort significantly. Within 60–75 days you will have your first harvest. Add a nitrogen liquid feed at two weeks after germination.
