1. Water

  • Don’t forget to water and mulch your plants. As we get into summer, watering becomes increasingly essential. 
  • In preparation for future water shortages, water plants more thoroughly but less frequently to promote deep roots.

2. Soil

  • To prevent weeds and keep the soil moist, spread a layer of compost and then cover the area with mulch.

3. Maintenance

  • Never let weeds go to seed by not keeping up with weeding.
  • Use fertilizer in accordance with the results of a soil test. 
  • Prepare flower and vegetable gardens for the summer by installing drip irrigation systems.
  • In the morning, take a stroll through the garden and remove any stink bugs or largus bugs you find. Their eggs can be found hidden under the leaves.
