Gaillardia aristata

Welcome to another episode of macro monday, a weekly event hosted by Lisa.Visit her blog for more stunning macro shots. Gaillardia is very tough perennial here standing in the extreme summer heat of lahore. This plant is not common for sale in nurseries, may be because it has committed the sin of being COMMON.

Can you believe these species are not available at nurseries, seeds are available though with the name 'bicolor'.

The parent of all these species is probably gaillardia grandiflora. Various varieties are sold in other countries but the ones in this post have gone wild and self sow easily.

Protecting Container Plants from Summer Heat

Protecting container plants in extreme summer heat is a challenge many gardeners face. Note that the plants in soil bed do not feel that much heat as compared to the ones in containers. In my case, i have got majority of my container plants on my terrace, the floor heats up in summers and the roots of plants at bottom of container are stressed. I had to water every second day to protect them. Last year i lost some of my plants because of that. Here is what i am doing this summer and this is going good so far.

Mulch: The best mulch components are leaf mold, coco peat and some organic matter or humus. You can also include, shredded newspapers and card boards. Remember, leaf mold cools the soil more than anything else. See the following arabian jasmine, though in soil bed, i have mulched it with leaf mold and coco peat around 2 inches depth.

This is how it will look closely. Don't forget to keep the mulch away from the main stem. Mulch will protect the plant from outside heat but not the bottom heat which is coming from the floor and stressing the roots.

Humidity: If your containers are at your terrace, the bottom heat will stress the roots of the plants. To handle this, place your container in a tray of pebbles soaked in water. But don't forget, your pot should not be standing in water, just the pebbles should be soaked and not the lower portion of your container. It is also useful for those plants which like humidity e.g. Arabian Jasmine etc.

Type of container: If you see below, this is my murraya exotica plant in an 18 inches clay pots. If you use terracotta pots, the terracotta color will protect the plants from heat however plastic pots heat up in direct sun. I like clay pots and they provide better protection from heat as well. The mulch of leaf mold and coco peat is 2 inches deep.
And last but not least container gardeners should try to plant drought tolerant plants as much as possible. The plants which are native to south africa, brazil, australia and mexico are very suitable to our sub tropical hot climate. The temperature outside temperature on my terrace right now is 110F which is quite challenging. But the mulch and pebbles tray are doing a great job till now.
