Dig In: Garden checklist for week of Sept. 4

Killer heat scorches Labor Day weekend; plan accordingly

Don’t let slightly cooler temperatures on Friday and Saturday fool you; this heat wave hasn’t hit its peak.

According to the National Weather Service, conditions for the next four days will be downright “dangerous.” An “extreme heat warning” is in effect for the Sacramento Valley and Sierra foothills from 11 a.m. Sunday through 8 p.m. Wednesday. A high of 115 degrees – which would be an all-time high for Sacramento – is possible.

“Very high risk of heat stress or illnesses for the entire population,” the weather service said Saturday. “Stay hydrated. Avoid being outdoors in the sun 10 a.m. to 6 p.m. … Stay in a cool place especially during the heat of the day.”

Those conditions are unsafe for animals of all kinds; keep pets indoors, too.

As for your garden, the best plan is to water early and deeply. Give plants the moisture they need to cope with this high heat. Container plantings are especially at risk; move pots to shady areas if possible.

With this heat also comes high fire danger. Do not use power tools or anything that could cause a spark to fly.

How hot can it get? The weather service predicts 112 degrees for Monday and Tuesday in Downtown Sacramento, although that could creep higher. Little relief will come after dark with overnight lows forecast in the mid 70s.

Temperature records likely will be set. Before this week, Sacramento’s hottest September day on record: 109 degrees.

Triple-digit highs will continue through Thursday before finally “cooling” to a mere 98 degrees Friday, says the weather service.

During this heat spell, take it easy outdoors and plan for cooler days ahead – like next week. The long-range forecast calls for low 90s by next Saturday and Sunday.

This week in the garden:

* Harvest tomatoes, peppers, squash, melons and eggplant. In this heat, pick sooner than later; they can turn overripe in a hurry.

* Compost annuals and vegetable crops that have finished producing.

* Deep-water shrubs and trees. Be on the lookout for plants stressed by this heat.

* In the morning, give plants a shower – especially if you see signs of spider mites. Take a hose and blast their webs off vines and bushes.

* Watch out for tomato hornworms. They love this heat, too.

* Indoors, start seedlings for fall vegetable planting, including bunching onion, cabbage, broccoli, cauliflower, kale, radicchio and lettuce.

* Sow seeds of perennials in pots for fall planting including yarrow, coneflower and salvia.

* One good thing about hot days: Most lawns stop growing when temperatures top 95 degrees. Keep mower blades set on high.

Dig In: Garden Checklist

For week of March 3:

* Celebrate the city flower! Catch the 100th Sacramento Camellia Show 3 to 6 p.m. Saturday, March 2, and 10 a.m to 5 p.m. Sunday, March 3, at the Scottish Rite Center, 6151 H St., Sacramento. Admission is free.

* Between showers, pick up fallen camellia blooms; that helps cut down on the spread of blossom blight that prematurely browns petals.

* Feed camellias after they bloom with fertilizer formulated for acid-loving plants.

* Camellias need little pruning. Remove dead wood and shape, if necessary.

* Tread lightly or not at all on wet ground; it compacts soil.

* Avoid digging in wet soil, too; wait until it clumps in your hand but doesn’t feel squishy.

* Note spots in your garden that stay wet after storms; improve drainage with the addition of organic matter such as compost.

* Keep an eye out for leaning trunks or ground disturbances around a tree’s base, a sign of shifting roots in the wet soil.

* Fertilize roses, annual flowers and berries as spring growth begins to appear.

* If aphids are attracted to new growth, knock them off with a strong spray of water or insecticidal soap. To make your own “bug soap,” use two tablespoons liquid soap – not detergent – to one quart water in a spray bottle. Shake it up before use. Among the liquid soaps that seem most effective are Dr. Bronner’s Pure-Castile Soaps; try the peppermint scent.

* Pull weeds now! Don’t let them get started. Take a hoe and whack them as soon as they sprout.

* Prune and fertilize spring-flowering shrubs after bloom.

* Cut back and fertilize perennial herbs to encourage new growth.

* Make plans for your summer garden. Once the soil is ready, start adding amendments such as compost.

* Indoors, start seeds for summer favorites such as tomatoes, peppers and squash as well as summer flowers.
