Rhubarb season is almost over but it is time to mulch tomatoes, continue deadheading flowers and fertilizing pots of annuals.
Patches of dead grass from the drought last summer are likely to fill in on their own if they are smaller than 6 inches. It is good to fertilize by mid-June to thicken the grass, shade weeds and add nutrients for roots and shoots.
Apple trees need pollen from a different variety to grow fruit. If there are other apple trees nearby in your neighborhood — even crabapple — one tree may be all you need to plant.
Gladiolus provide a favorite cut flower in summer, but the plants are susceptible to thrips. The plants can be sprayed, but the best control methods are applied to the corms when stored over the winter.
Award winners are hostas that are good garden plants in all regions of the country, are widely available in sufficient supply and retail for about $15 in the year of selection.
There is no official stance from the University of Minnesota on adopting a "No Mow May" approach to your lawn, in order to provide food for early pollinators. Both Wisconsin and Iowa Extensions recommend adopting a “Mow Less in May” routine.
Garden tools should be cleaned up now if that was not done last fall. Pots for annual flowers should have new soil each year, and the old soil can be worked into the garden. And soil tests aren't a bad idea either. Local Extension offices can help. It's also time to start hardening off any plant started indoors.
