Hot Weather Tips

In the hot weather, outside work continues, although I start earlier (sometimes 7am) so I can finish up by noon and retreat inside during the hottest part of the day.  I've been drying lots of culinary herbs - mints, basil, tarragon, thymes, catnip, chamomile, and savory.  I'm also drying flowers for use and sale in the shop - lavender is done, along with yarrow, love-in-a-mist seed pods, larkspur and cornflower.  Now I'm working on annual statice, showy kent beauty oregano and herrenhausen oregano.  These are both wonderful plants -grown not for flavor, but for their pretty flowers.

After perennial flowers have bloomed, it's a good idea to cut them back.  After blooming, they often decline in appearance.  Cutting them back hard - usually to a few inches above the ground, encourages the emergence of new growth.  You'll often see new growth at the base or in the middle of the plant.  This indicates the plant will benefit from hard trimming.  Some perennials will rebloom later in the season if they are cut back after their first bloom.

Lots of people have been admiring our hollyhocks once they bloomed.  They did not reseed particularly well this year.  I think many seeds rotted or washed away with last fall's flood.  But the ones that did come back are lovely.  So many people talk about a relative having hollyhocks in their yards.  Most do not remember them having rust.  Rust is a fungus disease caused by spores which proliferate in hot, humid weather.  Rust and other fungal diseases like powdery mildew must be treated with a fungicide.  Remember, it will not remove the fungus on the plant, it will only prevent it from getting worse.  In order to have clean plants, you must treat them before you see any signs of rust, and continue through the hot, humid weather.

Starting to see some more, larger butterflies - a couple monarchs, black swallowtails, and red admirals.  I saw a monarch feeding on butterfly weed.  This is a 'cousin' to wild milkweed and also swamp milkweed, which are host plants for the monarch caterpillars, as well as nectar sources for butterflies.

Our plant sale continues.  Lots of good prices!  Try a new plant or tuck in another in an empty spot in the garden.
