Keep your garden well watered during the hot seasons and ensure minimal water wastage. You can get a hose nozzle and a sprinkler to get the job done. Most sprinklers are adjustable and they can be set to work at different times even when you are away. This makes it less involving and more productive.
Use ice covers to your plants when it gets cold. Frost may cause small ice crystals to make within your plant and eliminate the normal, delicate skin of the place. Milk jug containers and other pockets might help assist you in making a closed environment around your place.
