By the month of June, all northern hemisphere gardens are in full throttle. Even the coldest zones have been planted and are ready for a bit of maintenance.
Warmer climates are still ahead of the game, shifting into a transition period northern gardeners don’t experience. But crops are still growing, insects are still feasting and, despite the heat and humidity, this is not the time to rest.
Spring is a mad dash to get the garden cleaned and planted. Come June, it may be tempting to simply sit back and enjoy your garden, but now is the time to turn to the true aspects of gardening -- tending to your plants and reaping the rewards. Keep in mind that you are not the only one who enjoys what you've planted. We're entering peak pest and problem season. So start (or refuel) your gardening engines and choose a few tasks from June's to do gardening list.
Task for All Hardiness Zones
- Work outside when it's less humid (early morning, late afternoon / evening).
- Keep new plants well watered.
- Check your mulch and reapply on bare spots before the weeds move in.
- Side dress with compost or manure or feed with fish emulsion, for mid-season pick-up.
- Check plant leaves for signs of nutrient deficiency.
- Give the compost a turn.
- Give your houseplants a summer vacation, by moving them outdoors.
- Make sure the birds have fresh water in birdbaths or shallow dishes in the garden.
- Stop harvesting asparagus and rhubarb. Let them build up reserves for next season.

- Get any remaining warm season vegetables (tomatoes, peppers, eggplant...) in the ground.
- Keep up on blanching your celery, cauliflower and tender greens.
- Plant a new batch of bush beans every couple of weeks.
