While each species has different watering requirements, it is critical to hydrate your plants thoroughly and deeply. Though overwatering is the most common way to kill a houseplant, the summer heat causes water to evaporate from the soil at a much faster rate. As a result, water your plants deeply and slowly. If you pour a lot of water into the soil, it does not have time to soak and simply drains through the drainage holes at the bottom, whereas if you water sparingly, only the topsoil is wet while the lower roots are dehydrated. Remember that by watering slowly, the water is actually absorbed..
Plants that require high humidity, such as tropical plants, must be misted frequently during hot periods. Fill your planter's base plate with pebbles or empty cans, fill it with water, and place your pot on top, or group your plants together and place a bucket of water in the middle to create a little humid microclimate for your plants that will provide humidity and help them through the summer. Shade-Resistant Plants:
Plants on a balcony facing south or west are especially vulnerable to leaf burn due to increased sunlight. As a result, it's critical to relocate them to areas that don't receive full-day direct sunlight and to water them thoroughly every morning.
You should try grouping plants together and shade more delicate varieties like ferns behind hardier and larger varieties.
When was the last time you gave your houseplants a drink? If the answer isn't recent, it's time to bring out the fertilizer and thoroughly mix it with the soil. Because of the longer days in the summer, plants are exposed to more sunlight, necessitating the need for additional nutrients to stay healthy and generate new growth. Water-soluble fertilizer once a month is sufficient for its health.
Always try to repot before the summers because if it's done during peak summertime, all of the activities of repotting like trimming of the root mass and leaves will put the plants at risk of shock and stress. So, save your repotting for cooler seasons when your plants' survival isn't a priority.
