We at Great Swamp Greenhouses hope that you and your families remain safe during this trying time. We are very grateful that we were allowed to remain open and thank you for your patronage! We have made the following changes in our store to ensure the safety of both our customers and employees.

  • Main aisle in greenhouse widened to 10ft
  • Two mobile/handheld registers to ring up Trees/Shrubs, Perennials and Bagged Mulch/Soil which is all spread out outside
  • Moving existing registers farther apart and installing plexiglass dividers
  • 6ft taped spacing for customers waiting to checkout
  • New POS system which allows you to use apple pay or insert your credit card without us touching it
  • Sanitizing carts, registers, and most surfaces multiple times a day
  • All staff wearing masks when in proximity of each other or customers.


In Store Changes

Yes you are allowed to shop both inside and outside our store. We have widened all the aisles (so even carts passing will still be 6ft apart) and have respaced all our registers. We also have two mobile registers and can ring you up outside if you prefer not to come in the store. We are past our busy season so you generally don’t need to worry about “crowds” this time of year.



We are happy to deliver Trees and Shrubs, Bulk Mulch and Topsoil, and other large ticket items within a wide local range.

We know many of you are trying to limit your time in store, so we have made this pre-shop list to help answer some of your questions as to whether we grew certain items or not.

Please note this is by no means an extensive list of what we carry, so if you are looking for something, please ask when you come in the store.

Warm Weather Vegetables

These veggies can not take a frost and there is always a chance in this area until around mid to late May. General rule of thumb is to wait until Mother’s Day and if the 10 day forecast will be above 40F at night, you are good to plant then.
