July jobs

Plant and sow

Sow fall carrots, beets, turnips and kohlrabi. West-side valleys
Set out fall broccoli, cabbage and kale starts late in the month. West-side valleys
Sow fall peas and bush beans early in the month. West-side valleys
Sow lettuce in a spot with afternoon shade so it doesn't bolt.

Start indoors

Start more brassicas for overwintering west of the Cascades: purple sprouting broccoli, winter cabbage. West-side valleys

Harvest

Garlic when the lower third of the leaves turn brown. Cure it somewhere shady and airy.
Zucchini every day or two, before they turn into marrows.
Beans, cucumbers, early tomatoes and raspberries.
Onions once the tops flop over. East-side valleys

Garden care

Water consistently. Uneven watering causes blossom-end rot on tomatoes and splits in cabbages.
Mulch thickly to keep roots cool.
Shade new seedlings and transplants during heat waves.

Pests and problems

Watch for powdery mildew on squash and cucumbers; improve airflow and water at the base.
Check tomatoes for late blight after any cool, wet spell. West-side valleys
Spider mites show up on stressed plants in hot, dry weather. East-side valleys

Fruit, berries and flowers

Cut summer raspberry canes that finished fruiting down to the ground.
Order garlic seed now for fall planting; good varieties sell out.
Keep picking flowers; dahlias bloom more the more you cut.
