DB Community Garden's last class in our Spring Gardening Series - Tomorrow (Friday, April 12 at 10am - 11:30am). Come learn how to help your plants in your garden deal with the extreme heat we get here in Diamond Bar. The tendency is to just water more, but is that really the answer? Some plants fair better than others when temperatures soar. For example, we here have a tough time growing the big steak tomatoes, but the small cherry tomatoes do better; ever wonder why (if you guess that heat might be a contributing factor, you're right).
And speaking of tomato plants, ever notice around 3 or 4 pm the plant is wilting and looks like it is in desperate need of water? It might, but it might not. Before you panic and run for the hose, put your finger or a soil moisture probe in the soil and check if the soil is dry or has enough moisture (just because the top 2" is dry, doesn't mean the plant needs water - you got to check the root zone). Plants sometimes take a break from the heat. I call it taking a seista; just like us, when we get over heated our bodies start to shut down. Well the plants are doing the same thing; its a way of coping - after all they don't have the luxury of getting up and moving to a shady spot to cool themselves down.
This is just one example of part of our topic tomorrow. Learning which plants are more sensitive to the heat, how to maybe pick plant varieties that are more heat tolerant, what is going on in the plants physiology when the heat is turned up and more.
We will discuss some techniques that you can incorporate into your summer gardens that will help you reach a successfully gardening experience.
